LUTHER All the formations represented on the area here considered belong to the Devonic system and except for a very minor part to the upper or Neodevonic division. The following formations are present: erautatnede Chemung sandstone and shale Prattsburg shale High Point (Portage) sandstone West Hill flags and shale Grimes sandstone Hatch shale and flags Rhinestreet black shale Cashaqua shale (including the Parrish limestone) Middlesex black shale Standish shale West River black shale Genundewa limestone Genesee black shale | Tully limestone Mesodevonic Erian Moscow shale These are considered in order from bottom to top. woe Neodevonic | Senecan 38 NEW YORK STATE MUSEUM The old group terms commonly employed in combining the units repre- sented in the above table have now entirely lost their value and hence do not appear here. In this and a previous paper the precise value of the geologic term Chemung is demonstrated and it now becomes a unit term in accordance with its original usage. Hence there is no place in the nomen- clature for the expression Chemung group, and its use involves an objection- able duplication of terms. On previous occasions also it has been shown that the High Point sandstones of the area next west are continuous with the original Portage sandstones of the Genesee valley; hence we can not wisely employ the term Portage group. Likewise the Genesee shales have been restricted to the lower measures of the group passing under this name and in accordance with the original intention the term becomes a unitname. Study of the typical sections of the Hamilton shale in Madison county makes it equally clear that the name Hamilton will not be advisedly employed except as a unit and not as a group term. Under the former grouping, the units here embraced under the term Senecan would be divided as follows from above down. (High Point sandstones | West Hill flags | Grimes sandstone Portave/ Hatch shale “©” \} Rhinestreet shale | Cashaqua shale | Middlesex shale | Standish shale ( West River shale Genundewa limestone Genesee shale Tully Tully limestone ) contain Chemung fossils in Ontario \ county Genesee MESODEVONIC Moscow shale The lowest formation exposed within the limits of these quad- rangles is the Moscow shale, of which there are a few small out- crops of its upper beds along the Keuka lake outlet between the Seneca paper mills and the east line of the quadrangle, half a mile below. In Bruce’s gully, a mile farther east, 40 to 50 feet of the upper part, capped by the Tully limestone, at the top of the falls, are finely exposed in the sides and bottom of the ravine. A vertical section of this entire formation is well shown in the gorge of Kershong creek at Bellona near the northeast corner of this quadrangle. It is composed of a mass of mostly soft, light bluish, gray cal- careous shales becoming darker toward the upper part. Thin layers of limestone usually extending but a few rods and irregular calcareous lenses, consisting principally of fossils, are of frequent occurrence. Normally the Moscow shale rests upon a stratum of limestone formerly called the Encrinal limestone but now known as the Tichenor limestone from its favorable exposure at and near Tichenor point, Canandaigua lake. In Ontario county the shale formation has a 5 GEOLOGY OF THE PENN YAN-HAMMONDSPORT QUADRANGLES 39 total thickness of 150 to 165 feet and the Menteth limestone, a stratum somewhat similar in character to the Tichenor and which has been sometimes mistaken for it, is interstratified 75 feet above the base. There are numerous exposures of the Moscow shale in central and western New York, among the most favorable of which eastward from this quadrangle are: along the east shore of Cayuga lake for ro miles north of Ludlowville; in ravines and cliffs at the south end of Skaneateles lake and Otisco lake; in the Fellows Falls ravine 2 miles west of Tully, and at Tinker’s falls near Fabius; and toward the west, in several ravines along both sides of Canandaigua lake between Tichenor point and Black point; along Little Beard’s creek at Moscow; along Murder creek and Ellicot creek near Darien; along Smoke creek at Windom, Erie co., and on Eighteen Mile creek and the Idlewild and South Baates cliffs on Lake Erie at North Evans. _ The characteristic fossils of the Moscow shale are listed in New York State Museum bulletin 63 to which the reader is referred. NEODEVONIC Tully limestone The Tully limestone is a bed of hard, dark bluish limestone that on exposure is inclined to separate into small angular blocks. It overlies the Moscow shale from Gorham, Ontario co. on the west to Smyrna, Chenango co. on the east and is exposed on the Penn Yan quadrangle at Seneca Mills on the Keuka lake outlet at 600 A. T., where it. produces a cascade 14 feet high. Here it occurs in several heavy layers that aggregate 12 feet in thickness. Some are compact and durable, but a large portion of the limestone, throughout the entire line of outcrop, has a sharp, brittle texture and, after exposure, breaks easily into small angular fragments. The extreme western outcrop of the formation is on Gage’s creek, 5 miles southwest of Gorham, Ontario co., and about 1 mile from Canandaigua lake. It is here 31 inches thick. It increases toward the east slowly to 28 feet at Tully, Onondaga co., and is not known east of Smyrna, Chenango co., where it consists -of several thin layers separated by shales. It is abundantly exposed along both sides of Cayuga lake in the vicinity of Ludlow- ville and northward to King’s Ferry and also on the east side of Seneca lake from Lodi Landing to Ovid. It appears in two small undulations on the west side of Seneca lake and -finally emerges from the water on the north side of Plum point. It is well exposed on the Keuka outlet, a mile below 40 NEW YORK STATE MUSEUM the outcrop at the Seneca mill, previously mentioned, and it forms the crest of the fall at Bellona. Fossils are usually found abund- antly in one or more layers at nearly all outcrops but the fossilifer- ous layers are not the same at all localities, and a large portion of the rock is almost barren. At Bellona the two upper layers are to a large extent made up of corals, many of them of great size. : The characteristic fossils of the horizon are: Hypothyris cuboides Sowerby and Schizophoria tulliensis Hall, with many species from the lower beds [see Mus. bul. 63]. Genesee black shale Lying next above the Tully limestone is a mass of densely black bituminous shale that on exposure becomes very fissile and splits into thin flat plates. Owing to their rigidity these shales are traversed by parallel series of joints from an inch to 3 feet apart intersecting each other at different angles and producing in cliff exposures striking effects like buttresses and bastions, and on surface exposures tessellations, triangles, rhomboids, diamonds and kindred forms. Rows of spheric concretions and thin calcareous layers occur, specially in the lower beds, and nodular masses of iron pyrites are common throughout the formation. Thin flags of sandstone appear in the upper part at some localities but they are not con- tinuous. The Genesee shale is abundantly exposed in the cliffs along the Keuka outlet between Keuka Mills and Seneca Mills and along the south branch of Kershong creek in the northeast corner of the Penn Yan quadrangle. On these quadrangles this formation is about roo feet thick. It diminishes gradually toward the east and disappears near Smyrna, Chenango co., and also toward the west, running out entirely in the town of East Hamburg, Erie co. It however reappears and is 12 inches thick on the shore of Lake Erie, 13 miles farther southwest at the mouth of Pike creek. The entire formation is exposed in numerous ravines and cliffs along the shores of Canandaigua, Seneca and Cayuga lakes and in the Genesee valley in Fall Creek ravine and in the ravine of Little Beard’s creek at Moscow, but not directly upon the banks of the Genesee river. Fossils are rare and poorly preserved in this shale. Lignites and conodont teeth occur very sparingly in the densely black beds 5 GEOLOGY OF THE PENN YAN-HAMMONDSPORT QUADRANGLES B41 -and the lighter shales carry a few specimens of Styliolina fissine tha Hal; Liorhynchts quadricostatum Pie herocwachia fragilas Halls Probelocerais lutheri Clarke; Lingula spatulata Vanuxem; Bac- Parres ache alam Hall: Orbiewloidea lodeén'si:s Hall; Pleurotomaria rugulata Hall. Genundewa limestone On the next quadrangle at the west and thence continuously to Lake Erie the Genesee black shale is overlain by a band of thin limestone composed almost entirely of the shells of a minute pteropod, Styliolina fissurella and designated the Genundewa limestone from its favorable exposure at Genundewa Point on Canandaigua lake. The horizon of this limestone is entirely covered by drift in the western part of the Penn Yan quadrangle and in the eastern part the limestones are not found although there are a*few exposures of the horizon. There is, however, a small outcrop of this rock in a small ravine on the east side of the Potter swamp, 14 miles north of the north line of this quadrangle and another 1 mile south of Fir Tree point on the west side of Seneca lake, 6 miles north of Watkins. On the west side of Seneca lake the horizon is plainly marked by a band of light gray calcareous shale 6 to 8 feet thick in which large flat concretions are common and near Fir Tree point form a con- tinuous layer. The representative fossils of the Genundewa lime- stone are abundant in the concretions and they also contain a number of additional species. The latter are in strong contrast to those of the preceding rocks and mark an invasion of an entirely new congeries of organisms into this region. This gray band may also be traced along the east side of Seneca lake and on both sides of Cayuga lake. It is finely displayed in the west bank of Salmon creek near the forks 2 miles south of Genoa. This formation is described and its interesting fauna cited in full in Museum memoir 6. West River black shale The West River shale, formerly known as the Upper Genesee shale, is composed of fine bluish black or dark gray shale with athin layer of black slaty shale at intervals of a few feet. Spheric and oblong concretions, many of which are septaria, are common throughout the beds singly or in rows and thin sandy flags occur specially in the upper part. 42° NEW YORK STATE MUSEUM These shales are contrasted with the Genesee shales below by their lighter color and less bituminous character, being mostly highly fissile and breaking into thin sharp laminae. The concretions are highly characteristic of these beds and in the region of their outcrop have been collected extensively on account of their curious shapes suggestive of turtle backs, human skulls and other rounded objects. Fossils are common but nowhere abundant. Fine specimens are occasionally found in the concre- tions. The following species occur in the beds: Bactrites aciculum Hall Pterochaenia fragilis Hall Gephyroceras sp. Lunulicardium curtum Hall Pleurotomaria rugulata Hall Lingula spatulata Vanuxem Buchiola retrostriata v. Buch. Orbiculoidea lodensis Vanuxem Panenka sp. : The West River shale is exposed on the Penn Yan quadrangle at the mouth of the Sartwell ravine 1 mile south of Penn Yan; also in a small ravine on the north side of the Keuka outlet 1 mile east of Penn Yan and on the east side of the Potter swamp along the road leading eastward to Voak. Other good exposures may be found in the ravine of Plum creek below Himrods; along the shore of Seneca lake at Smith’s point in the town of Starkey, and at Faucetts point 1 mile farther north . on the east side; in the Goodrich and other ravines in West River valley in the town of Middlesex; in several larger ravines on the sides of Canandaigua lake from Seneca point southward; in ravines along the sides ef Conesus lake; in the cliffs at the mouth of the Genesee River gorge at Mt Morris; in the ravine at Griswold 6 miles west of Attica and on the shores of Lake Erie near the mouth of Pike creek in the town of Evans, Erie co. On the western border of this quadrangle the West River shale has a thickness of r1ro feet and is overlain by a lighter colored and somewhat arenaceous band known as the Standish shales and flags, which are succeeded by a heavy bed of black shales called the Middlesex shales. By a gradual change in the character of the sedimentation the identity of these formations is lost before reaching the exposures of their horizons in the hortheastern part of this quadrangle, the Standish flags being eliminated from the rock section and the Middlesex black shale appearing, if at all, only as a few feet of darker and more bituminous shale at the top of the West River shales not separate from the latter formation, and the upper limit of the West River shale is not well defined. 5 GEOLOGY OF THE PENN YAN-HAMMONDSPORT QUADRANGLES 43 On the map a thickness of 100 feet is assigned to this formation. It is 65 feet thick on the Genesee river and 11 feet on Lake Erie. In the cliffs on the eastern shore of Cayuga lake, 4 miles north of Ithaca, the beds of this horizon are dark to black barren shales, next below the heavy sandstone that is in that locality the lowest member of the Portage group and about 35 feet thick. The Standish flags and shales, 15 feet thick, at the base of the Portage beds along Canandaigua lake and in the Middlesex valley are not accessible on this quadrangle. The formation is described in Museum bulletin 63. Middlesex black shale This is a well defined band of bituminous black shale overlying the West River shale and exposed in many outcrops in the Middle- sex valley 2 to 5 miles west of this quadrangle, and farther west to Lake Erie. It is 35 feet thick in the Middlesex valley and dimin- ishes to 6 feet on Lake Erie in the town of Evans, Erie co. There are no favorable exposures of this formation on this quad- rangle. It can be recognized in a few small outcrops on the east side of the Potter swamp in the vicinity of Voak, and at the mouth of the Belknap gully at Guyanoga. The formation is fully described in Museum bulletin 63. Cashaqua shale The Cashaqua shale is a heavy mass of light bluish gray or olive shales and sandstone appearing as the surface rock over a large area in the north part of the Penn Yan quadrangle and outcropping in the ravines and cliffs along the sides of both branches of Keuka lake and as far south as 1 mile north of Hammondsport on the west side and to a point opposite the village on the east side. At the base in the western part of the quadrangle there are 75 feet of laminated, rather sandy shales and thin flaggy sandstones that are succeeded by alternating beds of heavier, more compact sand- stones and soft argillaceous shales containing calcareous concre- tions, and, toward the south, more or less continuous concretionary calcareous layers. The entire formation becomes more arenaceous and less calcareous from west to east, but the upper beds on this quadrangle retain to a large degree the character and appearance of the beds in this horizon exposed along Cashaqua creek in Livingston county, the type locality of the formation, except that the sandstones are much heavier. One of the lowest of these com- A4 NEW YORK STATE MUSEUM pact layers has been quarried extensively in Cornwells gully, in the north part of Penn Yan and along the upper part of the Sartwell ravine 1 mile south of that village. These sandstones are broad lentils, usually becoming thinner and pinching out entirely in one direction and in the opposite after extending a considerable distance of perhaps several miles losing thickness by becoming shaly in the upper or lower part. They are the most prominent features in the stratigraphy of the formation and by their superior resistance to the eroding power of the streams as contrasted with the soft shales in the ravines have produced the numerous cascades and waterfalls that contri- bute so largely to the beauty of the scenery in the region about Keuka lake. In the Cashaqua shale is the Parrish limestone This limestone is interstratified in the Cashaqua shales 25 feet below the top in the western part of the Penn Yan quad- rangle, but the shale intervening between it and the overlying Rhinestreet shale thins out rapidly toward the south and east and disappears entirely a few miles beyond the east line of the Hammondsport quadrangle. ; This peculiar formation is an.impure concretionary limestone which, in the Parrish gully near Naples, is 4 inches thick and is rich in goniatites and other cephalopods. It does not extend west of the Naples valley but increases toward the east and south and reaches its greatest development, so far as exposed, about the head of Keuka lake. It is 6 inches thick in the gully at Friend, to inches in the Belknap gully at Guyanoga and in Wagener gully near Pulteney x: foot, 6 inches. In the ravine at Gibson Landing at 290 feet above the lake it is in four layers aggregating 2 feet, 6 inches. It dips under the water on the west side of the lake 50 rods south of Oak point and on the east side a mile farther south and directly opposite Hammondsport. In the small ravine on the east side at Rye point it is 100 feet above the lake, in the large ravine opposite Glen Grove 165 feet and in another, opposite Urbana, it is 6 inches thick and forms the crest of a 25 foot fall 211 feet above the lake level. It doubtless extends some distance farther north and east but changes in character to a calcareous nodular shale that does not resist erosion and rarely appears in outcrops. In Hewitts glen, 5 miles south of Penn Yan, it occurs as a shaly and lumpy limestone at 1000 A. T. 5 GEOLOGY OF THE PENN YAN-HAMMONDSPORT QUADRANGLES 45 It is exposed in the Big Stream gorge west of the Northern Cen- tral Railroad bridge, where it is a band of thin limestones and shales 5 feet thick overlain by the Rhinestreet black shale, the intervening light shales having thinned out and disappeared. Fossils are much less’ common in the Parrish limestone, on this quadrangle than in the Naples valley. MemuneoceLas pabtersonit Hallly Nornoceras wmromentare Conrad, Probeloceras-lutheri Hall and Orthocéeras pacator Hall are the more common cephalopods and Styliolina fissurella Hall is abund- ant. The Cashaqua beds are 230 feet thick on the Naples quadrangle. They are increased toward the north and east by the assimilation of the upper part of the Middlesex shales and lose by the thinning out of the soft shales between the Parrish limestone and the Rhine- street shale. The formation reaches its greatest thickness, 250 feet, in the region northwest of Penn Yan, and, decreasing gradually toward the southeast, is 207 feet thick in the vicinity of Watkins. Fossils are rare in the lower part of the Cashaqua beds, but occur in considerable numbers in a few layers, mostly in the upper part, of soft light colored shales. The fauna in this vicinity consists of species of 4 crustaceans, 16 cephalopods, 5 pteropods, 12 gastro- pods, 25 lamellibranchs, 4 brachiopods, 1 coral, 1 crinoid, 3 plants. The more common of these fossils are: Spathiocaris emersoni Clarke Buchiola retrostriata v. Buch. Manticoceras pattersoni Hall Ontaria suborbicularis Hall Probeloceras lutheri Clarke O. clarkei Beushausen Tornoceras uniangulare Conrad Lunulicardium acutirostrum Hall Hyolithus neapolis Clarke L. ornatum Hall Phragmostoma natator Hall - L. hemicardioides Clarke Loxonema noe Clarke Honeoyea major Clarke Paleotrochus praecursor Clarke H. erinacea Clarke Pterochaenia fragilis Hall Aulopora annectens Clarke Plumalina plumaria iscommonina 5 inch layer of shaly sandstone exposed in a small ravine west of the rock cut of the Northern Central Railroad 24 miles southeast from Penn Yan. See Museum bulletin 63 for full list of fossils. Rhinestreet shale This formation is a bed of black shale that overlies the Cashaqua shale from the Seneca lake valley where it is but 1 foot thick to the shore of Lake Erie in the town of Evans, Erie co., where it attains a thickness of 185 feet. It is 3 feet thick on the east line of these 46 NEW YORK STATE MUSEUM quadrangles and 15 feet on the western. In the exposure of this horizon in the Big Stream ravine it rests directly wpon the Parrish limestone, but. westward across these quadrangles a rapidly thick- ening bed of light shales intervenes and on the west side of Keuka lake it is 20 to 25 feet above that limestone and in the Naples valley 50 feet above it. East of the Genesee valley this formation is composed almost entirely of densely black bituminous shales, but farther west it includes several layers of lighter shales that contain a few of the fossils of the Cashaqua shales and rows of large spheric concretions. Fossils are exceedingly rare in the black shales but beds of land plants forming thin seams of lignitic coal are seen occasionally. The following species have been identified from the Rhinestreet shale in this vicinity. Paleoniscus devonicus Clarke Spathiocaris emersoni Clarke Acanthodes pristis Clarke Lunulicardium velatum Clarke Polygnathus dubius Hinde Pterochaenia fragilis Hall Prioniodus spicatus Hinde Leptodomus multiplex Clarke P. erraticus Hinde Lingula ligea Hall The Rhinestreet shale is well exposed in the ravine at Friend; in the Belknap gully at Guyanoga; in the Wagener ravine at Pulteney; at tooo feet A. T. in the small ravine 1 mile cast ar South Pulteney; in the Urbana ravine; along the lake shore south of Oak point and along the east side of the lake opposite Hammonds- port, also in the Rye Point and other ravines farther north to Grove Springs. In the region between Grove Springs and Crosby the Cashaqua shales and the lower beds of the Hatch flags and shales have an unusually large proportion of bituminous matter and the Parrish limestone does not appear. This condition together with con- siderable undulations of the strata makes identification of the horizon of the Rhinestreet bed somewhat uncertain, but its position is, approximately at least, as indicated on the map. Some of the best exposures of the Rhinestreet shale west of these quadrangles are along Rhinestreet and in Parrish gully at Naples; in Buck Run ravine at Mt Morris and in the Genesee River gorge in Smoky Hollow; in the ravine at Griswold 6 miles west of Attica; in the Eighteen Mile Creek gorge at North Evans; and along Big Sister creek below Angola, Erie county. The limits of the remaining formations shown on this map, though well defined on the Naples quadrangle, are very obscurely so on the , Hammondsport and Penn Yan quadrangles. 5 GEOLOGY OF THE PENN YAN-HAMMONDSPORT QUADRANGLES 47 Lithologically they all have the same general character and ap- pearance except as to the proportion of sandy sediments to the argillaceous and this is nowhere constant even in the same horizon. Very little assistance can be obtained in the determination of horizons from the fossils of these beds, specially in the Hatch shales and flags, for this is in the region, though on its western border, where extensions of the Naples fauna from the west and the Ithaca fauna from the east succeed each other, or are intermingled in afew thin layers. Correlation is therefore more a labor of careful tracing of formations from the type localities in the Naples valley than of detailed study of vertical sections. Undulations of the strata cause frequent changes in the dip and make accurate measurements of the thickness of formations well- nigh impossible. The figures given for these upper divisions are therefore estimates or arbitrarily assigned. Hatch shale and flags This formation is composed principally of shales, mostly soft and light blue or olive in color, but with frequent intercalations of layers of black shale from a fraction of aninch to 4feetin thickness. Flags and thin sandstones are liberally though very irregularly distributed. throughout the beds but appear more frequently in the middle and upper parts. These sandstones vary from an inch to 2 feet thick and are usually compact and hard on the lower surface but become shaly on the upper side. Some of them are laminated and on ex- posure separate into thin plates. Layers of this character occur in the Cashaqua shale and in all the formations on these quad- rangles above the Rhinestreet shale. The lower beds of the Hatch shale and flags are very much like the Cashaqua beds in appearance but in the upper part the changes from dark to light and hard to soft are more pronounced and in many old exposures the frequent flags projecting beyond the softer shales produce a coarsely stratified appearance. The proportion of sandstones is much gréater at some outcrops than at others in the same horizon. The formation is 300 feet thick on the western border of these quadrangles and increases slowly toward the southeast. It is the surface rock over a large area in the Penn Yan quadrangle but appears to be somewhat thinner and softer in the more northern exposures. It is well exposed in the upper part of the ravines at Friend; the Belknap gully at Guyanoga; the Wagener gully at Pulteney. The upper beds may be seen in the large ravine in the western part of Hammondsport and at that 48 NEW YORK STATE MUSEUM half a mile south of the village, also in the side of-the dugway road on the east side of the lake and in the Rye point and other ravines farther north. It outcrops in the road 4 mile southwest of Wayne and along the Bailey Gully stream and the highway a mile farther southwest. The drift sheet is thin over the large area where this is the surface formation, and small exposures are frequent along the sides of the roads and in the numerous small gullies on the hillsides. The Hatch shale and flags are abundantly exposed along the foot of Hatch hill at Naples, resting upon the Rhinestreet shale and capped by the Grimes sandstones, also in the Genesee River gorge from Smoky Hollow to the mouth of Wolf creek. They are softer and more calcareous in the vicinity of Lake Erie where they may be seen to good advantage in the ravine of Big Sister creek between Angola and Pontiac, and along the lake shore near Silver creek. On the Naples quadrangle the fossils occurring in the Hatch shale are all representations of the Cashaqua shale or Naples fauna, but much less in numbers. The following species may be found in the lower beds on this quadrangle: Manticoceras pattersoni Hall Lunulicardium ornatum Hail Probeloceras lutheri Clarke Honeoyea desmata Clarke Bactrites Buchiola retrostriata v. Buch. Paleotrochus praecursor Clarke On the Watkins quadrangle, adjoining on the east, a few repre- sentatives of the Ithaca fauna are found in the Hatch shale and flags. They are exceedingly rare here, though broken fragments of brachiopods too small for identification appear in some of the more calcareous sandstones. At 1250 A. T. in the Belknap gully a 6 inch sandstone contains: Spirifer mucronatus Covrad var. pos- Productella lachrymosa Hall terus Hall & Clarke Crinoid stems Schizophoria impressa Hall Grimes sandstone This formation is lithologically distinguished from the Hatch shale and flags only by the much larger proportion of arenaceous matter and consists of light blue-gray sandstones in layers from an inch to 3 feet thick separated by thin layers of hard, blue shale. The change in the proportion of sandstone and shale is very gradual at the bottom and also at the top of the formation, consequently its limits are very obscurely defined. This condition obtains through- out the entire extension of this formation across the western part of 5 GEOLOGY OF THE PENN YAN-HAMMONDSPORT QUADRANGLES 49 the State and is much emphasized east of the Naples quadrangle. The estimated thickness of the Grimes sandstones on these quad- rangles is 75 feet. It is not of great importance here except as a bench mark but at Naples it is a prominent feature in the stratig- raphy of the Portage rocks, producing high falls in the Grimes, Tannery and Parrish gullies, and escarpments on the hillsides. It is important there also as marking the close of the period during which sediments carrying the Naples fauna were laid down, and containing the earliest representatives of the Ithaca fauna in that locality. On the Watkins and Elmira quadrangles those faunas are inter- mingled in these beds, and it is probable that the same condition obtains here. _ The following species have been found in the horizon of the Grimes sandstones in the western part of the Penn Yan quadrangle or at Naples: Protonympha devonica Clarke L. quadricostatum Hall Schizophoria impressa Hall Leptostrophia mucronata Vanuxem Productella spinulicosta Hall Chonetes lepidus Hall P. lachrymosa Hall Ambocoelia umbonata Conrad Spirifer mesacostalis Hall Dictyospongia haplea Hall & Clarke Atrypa spinosa Hall Orbiculoidea sp.

Besides the exposures mentioned at Naples the Grimes sandstones may be seen in the cliffs at St Helena and at the mouth of Wolf creek in the Genesee River gorge and along the shore of Lake Erie between Silver Creek and Dunkirk. West Hill flags and shales The rock of this division consists of numerous thin, uneven flags, 2 to 4 inches thick and occasionally compact, even, blue sandstones 50° NEW YORK STATE MUSEUM t to 2 feet in thickness, separated by blue or olive shales. Layers» of black shale from an inch to 2 or 3 feet thick also occur. The proportion of sandstone decreases toward the east and south. Fossils are common in several of the heavier layers of sandstones lying 100 to 150 feet above the Grimes sandstones. In a small ravine that crosses the road leading to North Urbana 1 mile east of Hammondsport, there is exposed 4o rods above the crossing a cal- careous lens 1 foot, 6 inches. thick and several rods long almost entirely composed of brachiopods and crinoid segments, and several sandstones in the same horizon in the ravine 1 mile south of Ham- mondsport contain the same species. The more common are: Goniatites Atrypa spinosa Hail Orthoceras sp. Productella lachrymosa Hall Leptodesma sp. Ambocoelia umbonata Conrad Orthis tioga Hall Spirifer mesacostalis Hall Schizophoria impressa Hall Cyrtina hamiltonensis Hall Stropheodonta cayuta Hall Orbiculoidea sp. Leptostrophia perplana Conrad var. Crinoids nervosa Hall On the Hammondsport and Naples quadrangles the fossils of the West Hill flags and shales are mostly brachiopods, but in the Genesee river section and westward the fauna of the Naples beds prevails and brachiopods are absent. The West Hill flags and shales are exposed at the upper end of the ravine + mile south of Friend; the Belknap gully and the Wagener gully; and in field and roadside outcrops on the hill north of Hammondsport. The fossiliferous sandstones of this formation ° produce a series of low cascades in the ravine 1 mile south of Ham- mondsport at rr50 to 1200 A. T., and an exposure of the same hori- zon in the ravine near the corner of the Urbana road 1 mile east of Hammondsport includes the calcareous lens previously mentioned. There are frequent small outcrops of the West Hill flags at North Urbana and along the road to Wayne and the ravine at Bradford is in the softer beds in the middle of this division. There are exten- sive exposures of this formation on West hill at Naples and on East hill at Dansville. It is the upper part of the Gardeau flags in the Genesee river section and includes the strata displayed in the cliffs between the mouth of Wolf creek at St Helena and the high bridge of the Erie Railroad at the top of the Upper Portage falls. It appears in the cliffs along the shore of Lake Erie between Dunkirk and Barcelona. It is softer here and includes some heavy beds of black shale. GEOLOGY OF THE PENN YAN-HAMMONDSPORT QUADRANGLES. 51 High Point sandstone In structure and appearance the formation designated the High Point sandstone is on these quadrangles a repetition of the Grimes sandstone on a slightly enlarged scale. It is an arenaceous band about roo feet thick, in which the sandy layers are from 1 inch to 3 or 4 feet thick and the separating shales have the same range as to thickness and vary from light blue to black. The sandstones are somewhat lighter colored than those below and weather to a light gray except some calcareous layers that become rotten and rusty On exposure. The proportion of sandstone increases toward the west to the Gen- esee river where the formation is 185 feet thick and the proportion of shale is very slight. In the Genesee river section and westward to Lake Erie where it has gradually diminished to a few feet in thick- ness it is almost barren of fossils and no brachiopods have been found in it. At Naples, the typical exposure, the sandstones project from near the top of the formidable cliff at High Point and include a large calcareous lens composed of Chemung brachiopods and crinoids. The formation has been traced from Naples eastward and across these quadrangles to the vicinity of Elmira where lenses of similar character and appearance to the one at High Point are of frequent occurrence in it. The fossil contents of these lenses are exceédingly variable, no two of them being composed of the same species. The High Point sandstones are exposed in a small ravine 1} miles northeast of Italy Hill and acalcareous lensoutcrops three quarters of a mile north of that village. Small outcrops and a thin lens occur near the east and west road over the hill 2 miles north of Ham- mondsport. The sandstones outcrop at North Urbana and at Wayne Four Corners, also in a ravine and along the roadside 2 miles north of Sonora; near the mouth of the ravine 1 mile east of Savona and along a small stream that flows into Mead creek 1 mile north of Monterey. They are exposed in the quarries on East hill at Elmira and show an extensive calcareous lens.. West of the Genesee river they outcrop near Rock Glen in the Oatka valley and in Chautauqua county at Forestville, Laona and - Brocton. The horizon, with the sandstones almost entirely elimi- nated, dips under the water of Lake Erie 3 miles north of the State line. Fossils are not very abundant on these quadrangles’ except in the calcareous masses. 52 NEW YORK STATE MUSEUM The following are the more common species: Lyriopecten tricostatus Vanuxem Schizophoria impressa Hall Grammysia sp. Stropheodonta cayuta Hall Spirifer mesastrialis Hall Leptostrophia perplana Conrad var. Sp. mesacostalis Hall nervosa Hall Atrypa reticularis Linné Orthothetes chemungensis Conrad Productella lachrymosa Hall Tropidoleptus carinatus Conrad P. speciosa Hall Liorhynchus mesacostale Hall P. boydi Hall Chonetes scitulus Hall Orthis tioga Hall Lingula cf. melie O. carinata Hall Prattsburg shales and flags Above the High Point sandstones there is a partial return to argillaceous conditions and for about 250 feet the beds are mostly shales or thin, uneven, blocky or shaly sandstones. A few of the sandy layers are compact and hard and others are schistose or straticulate. In the Genesee river section at Wiscoy and vicinity these beds are soft, shaly and somewhat calcareous and contain only Portage fossils but eastward from that point they are harder and in the town of Prattsburg and on these quadrangles they contain many Chemung and very few Portage fossils. Toward the southeast they become softer again and at Elmira there is an approach to the conditions at Wiscoy. Although this formation is the surface rock over large areas on these quadrangles, outcrops that show more than a very few feet of the strata are rare owing to its elevation above the more deeply excavated parts of the ravines, except near the southern border where the drift mantle is quite heavy. It is partly exposed in the ravine 1 mile east of Savona and in another 2$ miles south of that Village, also in a ravine and along the roadside 2 miles north of Sonora. The more common fossils of the Prattsburg shales and sand- stones are: Paleoneilo filosa (Conrad) Hall L. spinigerum Conrad P. constricta (Conrad) Hall L. robustum Hall Lyriopecten tricostatus Vanuxem L. interplicatum Pterinopecten imbecilis Hall Spirifer mesastrialis Hall Macrodon chemungensis Hall S. mesacostalis Hall Mytilarea carinata Hall Productella lachrymosa Conrad Grammysia circularis Hall P. hirsuta Hall Leptodesma potens Hall P. speciosa Hail L. maclurii Hall Liorhynchus mesacostale Hall GEOLOGY OF THE PENN YAN-HAMMONDSPORT QUADRANGLES 53 L. multicosta Hall Atrypa reticularis Linné A. hystrix Hall Schizophoria impressa Hall Orthis tioga Hall O. carinata Hall Stropheodonta cayuta Hall Leptostrophia perplana Conrad var. nervosa Hall Stropheodonta demissa Conrad Orthothetes chemungensis Conrad Camarotoechia eximia Hall Ambocoelia umbonata Conrad Lingula spatulata Hall Chemung sandstones ~The Chemung sandstones and shales as defined in Museum bul- letin 81 are the surface rocks over the high lands in the southern part of the Hammondsport quadrangle, attaining in the extreme southeast corner in the town of Hornby a thickness of 560 feet. They are almost entirely covered by a thin mantle of drift or dis- integrated shale and sandstone, the few exposures being mostly the results of grading the highways. They are, however, uncovered sufficiently to show that, structurally, the formation is an aggre- gation of light and dark shales and blue gray sandstones, much like the West Hill flags and shales, except that many of the sand- stones are laminated or schistose and light gray or almost white in color. Calcareous lenses like those previously mentioned are more frequent and usually more extensive than those below. Fossils are abundant at all horizons and in nearly all outcrops of these beds, the more common species in this region being: Leptodesma longispinum Hall . billingsi Hall . shumardi Hall .spiniger (Conrad) Hall . disparile Hall . matheri Hall Paleoneilo filosa (Conrad) Hall P. constricta (Conrad) Hall P. emarginata (Conrad) Hall Lyriopecten tricostatus Vanuxem Microdon sp.

MUSEUM UNDULATIONS OF THE STRATA The aggregate thickness of the geologic formations and parts of formations represented on the map of the Penn Yan and Ham- mondsport quadrangles is approximately 2187 feet, of which 1535 feet are surface rocks by reason of the difference in elevation be- tween the point where the east line of the Penn Yan quadrangle crosses Keuka outlet 525 feet A. T. and the extreme southeast cor- ner of the Hammondsport quadrangle which is 2065 feet A. T. The total amount of the southward dip in the 34 miles across the two quadrangles from north to south is about 652 feet, an average of a fraction less than 20 feet a mile. The inclination of the strata is not constant in any direction ex- cept for short distances, and there are evidences of more or less disturbance throughout the whole of the area covered by the map. The sandstones of the beds that cover the southern part of the Hammondsport quadrangle are not reliable as bases for accurate determination of the size, shape and direction of the folds and un- dulations except in a general way. In the rock cut along the Northern Central Railroad 2} miles southeast of Penn Yan a com- pact sandstone 2 feet thick is exposed that is probably synchronous but not continuous with a stratum of similar character that appears at the mouth of Watkins Glen and the one assumed as the base of the Portage beds at Ithaca. In this cut the sandstone shows a strong dip toward the west, but at the west end it is 840 feet A. T. and in the Sartwell gully 2 miles farther west it appears at 880 feet A. T., 40 feet higher. It de- scends between this point and the quarry in the Cornwall ravine, 14 miles northwest, 35 feet and in the quarry dips northwestward at the rate of 52 feet a mile. The Tully limestone, from its outcrop at Seneca Mills, dips south- eastward to Plum point on Seneca lake at the average rate of 26 feet a mile and rises toward the north to Bellona at the rate of £6 feet a mile. Estimates based on other outcrops of the Tully zr mile east of that at Seneca Mills, where there is evidence of a con- siderable fault or very sharp fold, would give altogether different results. The strata show more disturbance in the region about Penn Yan than elsewhere on these quadrangles, and small anticlines or down- thrusts may be seen in nearly every ravine or outcrop in the vicinity. In a ravine on the west side of the lake 3 miles southwest from Penn Yan at about roo feet above the lake, a 4 foot sandstone that crosses the ravine is much broken and shows a diagonal fault or GEOLOGY OF THE PENN YAN-HAMMONDSPORT QUADRANGLES 55 downthrow toward the southeast of 9 feet. In the ravine at Crosby the sandstones dip toward the southwest at the rate of too feet a mile. The western side of the high ridge that separates Keuka lake and Seneca lake shows at all exposures a strong dip toward the west, that reaches in the north part of the quadrangles as far as the Naples valley. The dip is reversed in part at least on the Seneca lake side of the ridge as may be seen in the lower part of the Plum Creek ravine below Himrods where the strata dip toward the east for nearly a mile at the rate of 100 to 200 feet a mile. The Parrish limestone is exposed in a series of outcrops on the west side of the Keuka lake valley between Friend and Hammondsport, a distance of 13 miles on a nearly north and south line. In the ravine at Friend the lime- stone outcrops at 1095 feet A. T. and descends southward 45 feet or 18 feet a mile to the Belknap gully where it is roso feet A. T. This latter exposure is 11 miles directly east of the one in the Lincoln gully at Naples and 300 feet higher, an average descent toward the west of 27 feet a mile. From Belknap gully to the road leading west from Gibson Landing, which it crosses at 1005 feet A. T., the limestone descends 45 feet in 9 miles, a southward: dip of 5 feet a mile, and from this outcrop south and a little west to Oak point, where it disappears under the lake, it descends 296 feet in 6 miles, an average of 49 feet a mile. Owing to the western dip it is above the water about 14 miles farther south on the east side than on the west. From the place of its emergence on the east side of the lake to its outcrop in the ravine on the east side opposite Urbana, the dis- tance is 4 miles and the direction northeast. Between these points the limestone rises 165 feet or 41 feet a mile. The place where the limestone dips under the water opposite Hammondsport is 104 miles east and 14 miles south of the place where it is at the same elevation, 709 feet A. T. at Naples.

The heads of the several departments reported annually to the Governor the results of their investigations, and these constituted the annual octavo reports which were published from 1837 to 1841. The final reports were published in quarto form, beginning at close of the field work in 1841, and 3000 sets have been distribut comprising four volumes of geology, one of mineralogy, two botany, five of zoology, five of agriculture, and eight of paleontolog +e Sean Wa wy x w eore “INNO = ase a ie es 2 SY Uy = | = oe = w) a = \RIES SMITHSONIAN INSTITUTION NOILOLILSNI 4ES LIBRARIES S3IYVYGIT LIBRARIES SMITHSONIAN _INSTITUT = INSTITUTION NOILNLILSNI ww 2 AZ S3SIYVYNUSIT LIBRARI INSTITUTION NOILNLILSNI SSIY¥VYEITLIBRARIES Satuvugl \RIES SMITHSONIAN INSTITUTION NOILALILSNI NVINOSHLINS S3luVv x NVINOSHLIWS Tr JILSNI_NVINOSHLINS S3IYVYAIT LIBRARIES SMITHSONIAN _ INSTITUT NVINOSHLIWS NVINOSHLIWS = SMITHSONIAN SMITHSONIAN NOILNLILSNI LIBRARIES LIBRARIES NOILNLILSNI ARIES SMITHSONIAN INSTITUTION NOILALILSNI NVINOSHLINS S31uVvd INSTITUTION NOILNLILSNI INSTITUTION sa1uvugin ILILSNI NVINOSHLINS S3SIYVYUEIT LIBRARIES wf + INSTITUTION SMITHSONIAN INSTITUT NVINOSHLINS S3tuvudgl SMITHSONIAN NVINOSHLIWS NS ANG SY SMITHSONIAN SMITHSONIAN Wi artim fe) 6 6 AR EAITLIM PRAIA RS PRPC TRTTITRSUAT OCR PR EEF AE.
