CLARKE, Director Museum Bulletin 152 GEOLOGY OF THE HONEOYE-WAYLAND QUAD- RANGLES By D. DANA LUTHER The Honeoye-Wayland quadrangles are included between the lines of latitude 42° 30' and 43° north, and of longitude 77° 30' and 77° 45' west and contain one-eighth of a degree, or about 441 square miles of territory. The rocks of these quadrangles have an estimated aggregate thickness of about 2660 feet, of which 1510 feet are surface rocks because of the difference in altitude between the lowest outcrop, which is on Honeoye creek near Sibleyville at 590 feet A. T., and the highest, at the top of Sand hill near the south line of the Wayland quadrangle at 2100 feet A. T. Eleven hundred and fifty feet of strata are brought to the surface by their elevation toward the north at an average rate of about 33 feet per mile. These rocks embrace the following geological subdivisions or formations, twenty-four in number, which are represented by dis- tinctive colors on the accompanying map. 333205 "NfiW YdRK STATE MUSEUM Devonic Senecan Erian Ulsterian Ontario Cayugan or Siluric Chemung shale and sand- stone Wiscoy shale Nunda sandstone Gardeau flags and shale Grimes sandstone Hatch shale and flags Rhinestreet black shale Cashaqua shale Middlesex black shale West River shale Genundewa limestone Genesee black shale v.

GEOLOGY OF THE HONEOYE-WAYLAND QUADRANGLES 7 The Camillus strata are entirely covered on these quadrangles, but are exposed at Victor on the Canandaigua quadrangle and at Wheatland and Garbuttsville on the Srockport quadrangle. — BERTIE (AND COBLESKILL?) WATERLIME The Camillus shales are succeeded by 85 to 100 feet of water- limes varying in character from hard, flaggy layers to beds of soft dolomite in which lines of deposition are very obscure. At the top of this formation, in the vicinity of Honeoye Falls, there are exposed 35 feet of waterlime, of which 3 feet 6 inches at the top are in uneven layers 2 to 6 inches thick and break easily into small rough blocks. It is quite probable that this stratum, which some- what resembles the " bullhead " of Erie county, should be correlated as Cobleskill waterlime, but no fossils are found in it. Next below these are 20 feet of hard waterlimes showing faint lines of bedding. Some parts have no regular fracture. In this vicinity, this bed has been quarried quite largely for building purposes. The underlying ten feet of rock are flaggy and at one or two horizons quite shaly. The lower beds are generally softer, and in some parts shaly, but there are thin hard layers separated by thin partings of black bituminous matter and heavier strata of softer waterlimes that have no regular fracture. The contact with the Camillus shales is not exposed on this quadrangle. The waterlimes are exposed along the Hemlock outlet in the village of Honeoye Falls below the milldam east of the high school building, and along the stream to below the Lehigh Valley Railroad bridge. There are quarries in the upper beds east and west of the south end of this bridge, where the contact with the Oriskany hori- zon also appears. There are good exposures of forty feet of the upper beds along Spring creek two miles west of Honeoye Falls, and in the large old quarry one- fourth of a mile south of the New York Central Railroad bridge over this stream. There is a small exposure of waterlime near an old limekiln one and one-half miles west of Spring creek with the Onondaga limestone five feet higher, and small outcrops of this rock occur in the bed of Stony brook at Five Corners. In the central part of the State and in Erie county the waterlime beds contain fossils of several species, but the strata exposed on this quadrangle are almost barren. Leperditia alta (Con- rad) and Whitfieldella laevis (Whitfield) are the only forms observed. 8 NEW YORK STATE MUSEUM In the salt shaft near Livonia on the Honeoye quadrangle the following fossils were found in these beds : Spirifer vanuxemi Hall Stropheodonta varistriata (Conrad) Liopteria rugosa Hall Leperditia alta (Conrad) and a small Favosites DEVONIC ORISKANY SANDSTONE This formation is represented here by eight inches of gray cal- careous sandstone containing no fossils. It is exposed in the rock wall along Hemlock outlet at the dam east of the high school at 634 A. T. in Honeoye Falls and also at the south end of the Lehigh Valley Railroad bridge one-half mile northwest of the village. In the Livonia salt shaft there were at this horizon five feet of coarse, green and gray conglomerate containing eight species of brachio- pods, suggestive of a commingling of the faunas of the Oriskany sandstone and Schoharie grit of the eastern part of the State. They are Pentamerella cf. arata (Conrad) Atrypa reticularis (Linne) Orthis cf. propinqua (Hall) Hipparionyx proximus Vanuxem Stropheodonta sp. Pentagonia unisulcata (Conrad) Spirifer cf. arenosus Conrad ONONDAGA LIMESTONE. The Onondaga limestone is composed of layers or tiers of blue gray limestone, separated by partings of dark shale or black bitum- inous matter. Dark chert or impure flint in nodules or nodular layers is un- evenly distributed throughout nearly the entire formation, but is in larger proportion in the lower part, except for an uneven stratum two to five feet thick at the base, which is largely composed of corals and from which chert is absent. The cherty lower beds supply the material for the crushed stone used in roadmaking and for ballast, while the basal stratum and the layers clear from chert found in the upper part of the forma- tion furnish an inexhaustible supply of valuable building stone and quicklime. GEOLOGY OF THE HONEOYE-WAYLAND QUADRANGLES Q The entire section of this formation is exposed along Honeoye creek from the Monroe milldam in Honeoye Falls to the north side of the bend half a mile south of North *Bloomfield, except for a small hiatus in the middle of the formation between the two villages. The lower beds may be seen along the bed of Spring creek and the upper tiers in the quarry of the Genesee Lime Company two miles southwest of Honeoye Falls. The basal layer, specially rich in corals, outcrops over an area of half an acre near an old limekiln three miles west of Honeoye Falls near a north and south road one and one-eighth miles west of Spring creek. Some of the lower tiers outcrop in the road south of Five Corners, and there are several field outcrops farther south in the region drained by Stony brook. The fauna of the Onondaga limestone is very large ; a list of species found in this formation, given in State Museum Bulletin 63, contains 3 fishes, 39 crustaceans, 13 cephalopods, 3 pteropods. 38 gastropods, 15 lamellibranchs, 48 brachiopods, 4 crinoids and 30 corals ; total 193. MARCELLUS BLACK SHALE The blue Onondaga limestone is succeeded by black, carbonaceous shales and soft, dark impure limestones to the thickness of 41 feet in the Livonia salt shaft but somewhat thinner on the line of out- crop. On these quadrangles this shale is terminated at the top by the Stafford limestone, and it constitutes the lower division of the " Marcellus shale," as described by Hall and Vanuxem. The lower beds are mostly calcareous and fossiliferous, while the upper are composed mainly of densely black bituminous and pyri- tiferous shale in which occur spherical concretions six inches to one foot, six inches in diameter. This formation is rich in hydrocarbons and is the source of the natural gas produced by the shallower gas wells of this region. Many of the concretions are septaria and the cavities within them occasionally contain- a small quantity of petroleum. On account of the compact character of this rock, gas wells terminating in it are not very productive except when a crevice or large pocket is penetrated. Fossils are abundant, specially in the lower more cal- careous part on this formation. The following species were found in the Marcellus shale and limestone in the Livonia salt shaft, in the upper black shale and concretions : IO NEW YORK STATE MUSEUM Plates of Aspidicthys and Dinichthys halmodeus (Clarke) Orthoceras nuntium Hall O. subulatum Hall ' Tornoceras uniangulare (Conrad) Cyrtoceras citum Hall Pleurotomaria rugulata Hall Styliolina fissurella Hall Panenka lincklaeni Hall P. equilatera Hall Nuculites nyssa Hall Pterochaenia fragilis (Hall) Liopteria laevis Hall Pterinopecten dignatus Hall Actinopteria muricata Hall Orbiculoidea minuta Hall Liorhynchus limitare (Vanuxcm) Chonetes mucronatus Hall The following additional species occur in the more calcareous beds near the base of the formation: Phacops rana Green Orthoceras incarceratum Clarke O. lima Hall Tentaculites gracilistriatus Hall Pleurotomaria lucina Hall Aviculopecten cf. fasciculatus Hall Modiomorpha subalata (Conrad) M. concentrica Hall Cypricardinia indenta (Conrad) Microdon bellistriatus (Conrad) Nuculites oblongatus Conrad Palaeoneilo plana (Conrad) Tropidoleptus carinatus (Conrad) Spirifer audaculus Conrad Ambocoelia umbonata (Conrad) A. praeumbona Hall Athyris spiriferoides (Eaton) Coelospira Camilla Hall Terebratula sp.

STAFFORD LIMESTONE This formation takes its name from Stafford, Genesee county, where it is well exposed. It is eight feet three inches thick at Lancaster, Erie county, but diminishes gradually toward the east, and at its extreme eastern exposure on Flint creek, Ontario county, is but four inches thick. On this quadrangle it is a hard blue limestone, in one stratum 14 to 1 8 inches thick with a few inches of calcareous shale above and below. There are no exposures of the Stafford limestone on these quad- rangles but it may be seen below the second dam on Conesus outlet west of Ashantee, and in the bed of Little Conesus creek east of the Erie Railroad bridge. The Stafford limestone is rich in fossils at every exposure and a list published in State Museum Bulletin 49 contains the names of 118 species which have been collected from it. This stratum occurs in the Livonia salt shaft at the depth of 823 feet and contained the following forms: Phacops rana Green Orthoceras aedipus Hall O. cf. marcellense Hall Loxonema delphicola Hall Pleurotomaria sulcomarginata (Conrad) P.itysHall P. lucina Hall Meristella barrisi Hall 12 NEW YORK STATE MUSEUM Camarotoectu'a sappho Hall C. horsfordi Hall Chonetes scitulus Hall C. mucronatus Hall Strophalosia truncata Hall Ambocoelia umbonata (Conrad) Orthothetes arctostriatus Hall Spirifer subumbona Hall S. audaculus (Conrad) Atrypa recticularis Linnc Panenka lincklaeni Hall P. aequilatera Hall Pterinopecten exfoliatus Hall Actinopteria muricata Hall Aviculopecten bellus Conrad Styliolina fissurella Hall CARDIFF SHALE The shales succeeding the Stafford limestone and formerly known as upper Marcellus, are richly bituminous, though in a somewhat less degree than those below, for about sixty feet gradually becom- ing more argillaceous and lighter colored, and passing into the next higher formation. The only exposure of the Cardiff shale on this quadrangle is along Little Conesus creek between the Erie Railroad bridge and the Avon reservoir. In the Livonia shaft section these beds were penetrated at 753 to 823 feet and the following species were found in them : Tornoceras uniangulare (Conrad) Orthoceras subulatum Hall O. nuntium Hall Cyrtoceras sp. Pleurotomaria rugulata Hall P. capillaria (Conrad} Bellerophon leda Hall Liopteria laevis Hall Modiella pygmaea (Conrad) Pterochaenia fragilis (Hall) Actinopteria muricata Hall Buchiola retrostriata v.

It is 145 feet thick and is terminated at the top by a stratum of hard calcareous sandy shale containing cyathophylloid corals in abundance. Skaneateles shale is exposed along Little Conesus creek below the Avon reservoir, but is not seen elsewhere on these quadrangles.- Its place in the Livonia shaft section is 608 to 753 feet below the top. The following fossils occur in these beds : Phacops rana Green Cryphaeus boothi Green Tornoceras uniangulare (Conrad) Orthoceras exile Hall « Gomphoceras sp.

Cal- careous concretions are quite common, and 65 feet above the base and near the top there are even layers of limestone one to two feet thick. The Ludlowville shale is terminated at the top by the Tichenor limestone. The basal hard layer, which is a coral reef at Centerfield, Ontario county, and a calcareous sandstone in the Livonia shaft section, is exposed at an old mill site on Littl£ Conesus creek near the Avon reservoir, but is almost entirely devoid of fossils. Along Gates creek two miles north of Aliens Hill 15 to 20 feet of the shales next below the Tichenor limestone are exposed. This formation was named from its exposure along the shore of Cayuga lake near Ludlowville, Tompkins county. It extends across central and western New York and is everywhere richly fossilifer- ous. Lists of the fossils composing its fauna may be found in volume i of the Report of the State Geologist for 1893 and in State Museum Bulletin 63. TICHENOR LIMESTONE A stratum of limestone about one foot in thickness overlies the Ludlowville shale from Cayuga county to Lake Erie. It was known by the geologists of the early State Survey as the Encrinal lime- stone and serves as a bench mark in the stratigraphy of the western part of the State. The name Encrinal limestone was applied to the stratum on account of the abundance of c/inoid fragments which it contains and of which it is, at some localities, almost entirely com- posed. A calcareous stratum of somewhat similar appearance to the Tichenor limestone which occurs at the base of the Ludlowville shale and outcrops at Centerfield on the Canandaigua quadrangle, on the Attica quadrangle and other places in western New York, has some- times been erroneously identified as the Encrinal, hence a more specific name has proved desirable. The favorable exposure in Tichenor gully on the west shore of Canandaigua lake suggested the present name. A small exposure on Gates creek near the old mill- dam is the only one on these quadrangles where Tichenor appears. The following is a partial list of the fossils that occur in it : Phacops rana Green Orthoceras caelamen Hall GEOLOGY OF THE HONEOYE-WAYLAND QUADRANGLES 15 Diaphorostoma lineatum (Conrad) Lyriopecten orbiculatus Hall Spirifer mucronatus Conrad Sp. granulosus (Conrad) Heliophyllum halli Edwards & Haime Favosites argus Hall F. arbusculus Hall Eridophyllum sp. Heads of Megistocrinus and other crinoids are sometimes found in the soft shale that immediately overlies the limestone. MOSCOW SHALE Succeeding the Tichenor limestones there are 147 feet of shale, in which calcareous concretions and thin calcareous lenses, com- posed largely of crinoid and other fossils, are common. The principal part of the shale is light bluish gray and quite calcareous, but at some horizons it is quite dark. Iron pyrite in nodules is common, specially in the upper beds and occasionally occurs in the shape of casts of small fossils. East of Canandaigua lake the upper limit of this formation is the base of the Tully limestone which does not extend west of the town of Gorham, Ontario county, but in its place there is found at some exposures a thin layer of iron pyrite separating the blue Moscow shale from the black Genesee. The upper part of the Moscow shale, with overlying pyrite layer and Genesee shale, is exposed along Hemlock creek south of Rich- mond Mills, and the base of the formation on Gates creek (some- times called Beebe brook). Its place in the Livonia shaft section is 280 to 427 feet from the top. This formation is very rich in fossils. For lists of species see 1 3th Report of the State Geologist, volume i, 1893, and State Museum Bulletin 63. PYRITE LAYER. HORIZON OF TULLY LIMESTONE The formation ot hard limestone, named from its best develop- ment at Tully, Onondaga county, where it has a thickness of 28 feet, thins out toward the west and disappears on the east side of Canandaigua lake. Westward across the Canandaigua and Honeoye quadrangles lentils of iron pyrites from one to four inches thick and 1 6 NEW YORK STATE MUSEUM two to ten rods across, occur in the horizon of the Tully limestone so frequently as to appear at nearly every exposure of the Moscow- Genesee contact. When freshly exposed the stratum is extremely hard and refractory, but it softens and disintegrates in very old exposures, its position in the walls of ravines being usually indicated by a thin rust-colored band. Fossils of 48 species have been identified from this layer in On- tario and Livingston counties. A full description of the pyrite lentils and a list of its fossils may be found in State Museum Bulletin 69, 1903. GENESEE BLACK SHALE Overlying the pyrite layer or, in its absence, the Moscow shale, there is a bed of black bituminous shale similar in appearance to the Marcellus shale 500 feet lower in the strata. As commonly used, the term applied to these strata has included the succeed- ing Genundewa limestone, the dark West River shale and the black Middlesex shale above it. As here used, the term Genesee black shale designates the strata between the Tully horizon and the Genundewa limestone, which on these quadrangles have a total thickness of 85 to 90 feet. The shales are mostly densely black and contain a proportion of hydrocarbons sufficiently large to produce, when freshly broken, a natural fetid odor. Pyrite in small nodules is common. Rows of spherical concre- tions and a few thin flags of fine grained calcareous sandstone, also occur. Fossils, except a few plant remains, are almost entirely absent from the black shale and are rare in the lighter beds. The follow- ing have been obtained from the Genesee shale in this region : Conodont teeth Pleurotomaria rugulata Hall Probeloceras lutheri Clarke Bactrites aciculum (Hall) Styliolina fissurella Hall Pterochaenia fragilis (Hall) Lingula spatulata Hall Orbiculoidea lodensis Hall Liorhynchus quadricostatus Hall , Exposures of Genesee shale may be found on the Honeoye quadrangle in two ravines on the east side of the valley two miles north of the village of Honeoye, along the Hemlock outlet one to GEOLOGY OF THE HONEOYE-WAYLAND QUADRANGLES I/ two miles north of Hemlock village, and in the ravine on the west side of Conesus lake near Eagle point, GENUNDEWA LIMESTONE This designation has been applied to a band of thin impure lime- stones separated by partings of a few inches or feet of black shale, the whole having a total thickness of six to eight feet. Some of the limestone layers are very uneven and somewhat nodular, while others are even and compact; one of the latter, twelve to fourteen inches thick, has been utilized to a limited extent for building purposes. The limestones are composed principally of the minute shells of the pteropod Styliolina fiss-urella Hall and the forma- tion was formerly known as the " Styliola band." These shells give the limestone a sandy appearance after long exposure. This forma- tion is exposed in two ravines two miles northeast of Honeoye and in the bed of Whetstone brook two miles northwest of Honeoye. It may be seen in a gully near the first bridge over the Hemlock outlet below Hemlock village, and in a larger ravine half a mile farther north. It appears fifty feet above the lake level in the ravine near Eagle point, Conesus lake. Fossils are abundant in this formation, and the fauna is of pecu- liar interest owing to the appearance of many forms not known to occur in the rocks below. A list of fossils numbering forty-eight species, obtained from the Genundewa strata, may be found in State Museum Bulletin 63. WEST RIVER DARK SHALE Succeeding the Genundewa limestones there are 65 to 75 feet of dark gray shale in which there are interstratified beds of black shale one to three feet thick, at intervals of three to eight feet, which, in walls of ravines, give this formation a broadly banded appearance. Calcareous concretions are common; some of these are septaria and have been known under the names " petrified tur- tles," " niggerheads " and others of similar character. A few thin flags of calcareous sandstone also occur. At the top the passage to the succeeding black Middlesex shale is through several alternations of dark and black shale in a few feet. The West River shales are exposed along Whetstone creek two miles northwest of Honeoye; in all the large ravines toward the l8 NEW YORK STATE MUSEUM west to Hemlock lake; on Conesus lake in the ravines between Old Orchard point and McPherson point, on the east side, and between Eagle point and Long point on the west side. Fossils are rare in the West River beds. A few individuals of the following species occur: Bactrites aciculum (Hall) Gephyroceras sp.f Pleurotomaria rugulata Hall Buchiola retrostriata v. Buck Pterochaenia fragilis (Hall) Lunulicardium curtum Hall Panenka sp. Lingula spatulata Vanuxem Orbiculoidea lodensis Vanuxem Melocrinus clarkei Hall MIDDLESEX BLACK SHALE A bed of black shale similar in appearance to the Genesee beds, succeeds the West River shales to the thickness of 30 to 35 feet. As the transition to the adjacent formations is gradual both above and below, the assigned thickness is somewhat arbitrary. It may be recognized beneath the lighter Cashaqua shale as far east as Cayuga county, where it ceases to be separable from the West River shale. Toward the west it is more distinctly differentiated from the adjacent formations and on the shore of Lake Erie it is a homogeneous band of black slaty shale six feet thick. This formation is exposed in the ravines in the Honeoye Lake valley and in the region two miles south of Richmond Mills. It is finely displayed on the road one-half mile southeast of Hemlock and in the ravine at Glenville. It also appears in all of the ravines on both sides of Conesus lake in the vicinity of McPherson point. Fossils are exceedingly rare in the Middlesex shale. The follow- ing occur: Plant remains Fish remains Conodonts Sandbergeroceras syngonum Clarke Ontaria suborbicularis (Hall) GEOLOGY OF THE HONEOYE-WAYLAND QUADRANGLES IQ CASHAQUA SHALE The black shales are succeeded by nearly 200 feet of light col- ored bluish gray or olive shale, in which thin flags occur occa- sionally, and a few thin layers of black shale are interstratified. Calcareous concretions, and thin concretionary layers, continuous for but a short distance, are common in the higher portion of the formation. Occupying a position between two heavy beds of black shale it is easily recognized by its lighter color and peculiar structure, wherever it is exposed, from Seneca lake to Lake Erie, and its peculiar and interesting fauna has made it the subject of careful study, the results of which, with a list of its fossils, may be found in State Museum Bulletin 63 and Memoir 6. The Cashaqua beds are abundantly displayed in a very large number of ravines on these quadrangles. Among the more favor- able and accessible exposures are the uppeV beds of Whetstone creek two miles west of Honeoye and the lower along the road half a mile southeast of Hemlock ; along Canadice outlet above the Glenville mills ; in Shurger's glen two and one-half miles west of Hemlock; in all of the large ravines on both sides of Conesus lake, and the upper beds at the mouth of the two large ravines on the east side of the valley half a mile south of the head of the lake. RHINESTREET BLACK SHALE „ The band of black shale that succeeds the Cashaqua shale and has a thickness on these quadrangles of 30 to 40 feet, was formerly known as the " upper black band." It was designated as above in State Museum Bulletin 63, from its exposure at the locality in the Canandaigua lake valley known as Rhinestreet, where it is 22 to 25 feet thick. It increases rapidly toward the west and on Lake Erie is 150 to 185 feet thick. It is a well-defined band of slaty, bituminous black shale between formations of much lighter color, and, having greater power of resistance to erosive forces than those beds, it frequently produces cascades in the ravines along the line of outcrop. . It appears at most of the exposures of the upper Cashaqua beds in these quadrangles. It is seen to great advantage in the walls of the amphitheatre in the ravine of Whetstone creek half a mile south of the Honeoye-Hemlock road. It is also well exposed in Shurger's gully two and one-half miles west of Hemlock ; in the two ravines half a mile south of the head of Conesus lake, east 2O NEW YORK STATE MUSEUM side, and in a Delaware, Lackawanna & Western Railroad cut, at the west line of the Wayland quadrangle. The fauna of the Rhinestreet shale is very limited. The follow- ing list shows the species that have been identified from it: Polygnathus dubius Hinde Prioniodus spicatus Hinde P. erraticus Hinde Palaeoniscus devonicus Clarke Acanthodes pristis Clarke Spathiocaris emersoni Clarke Lunulicardium velatum Clarke Pterochaenia fragilis (Hall) Leptodomus multiplex Clarke Lingula cf. ligea Plant remains are common, sometimes occurring in masses. HATCH SHALE AND FLAGS Next above the Rhinestreet shale there is a partial return to the conditions in the Cashaqua beds below, though the light shales are harder and less calcareous, and flags and thin sandstones are more frequent. A few bands of black shale are interbedded, but on the whole the principal lithologic difference between this forma- tion and Cashaqua shale is in the proportion of sandy sediment, which is* considerably larger in these beds and increases upward to the top, where they are succeeded by the Grimes sandstones. About 200 feet of strata are embraced within this formation, which was named from its abundant exposure on Hatch hill at Naples, Ontario county. There are many small exposures of these rocks in fields and ravines and along the highways, but only a few are sufficiently extensive to afford opportunity for satisfactory examination of them. The best are along the road* side and in a small ravine two miles southwest of Honeoye; in some small gullies on the west side of Canadice lake; along the roadside two miles north of Cemetery hill; in the north ravine near the head of Conesus lake, and the Calabogue ravine at Cone- 'sus, where the entire formation may be seen under favorable con- ditions. In the Canaseraga creek valley the lower part of all the ravines on the east side between West Sparta and Dansville show Hatch shales and flags. They also appear on the west side north- ward from Cumminsville. GEOLOGY OF THE HONEOYE-WAYLAND QUADRANGLES 21 Fossils are very rare here. The softer shales in the lower beds contain a few forms like those found in the Cashaqua. The sandier beds are quite barren except of plant remains. The col- lector may expect to find: Manticoceras pattersoni (Hall) Probeloceras lutheri Clarke Lunulicardium, ornatum Hall Honeoyea desmata Clarke Buchiola retrostriata (v. Buck) Palaeotrochus praecursor Clarke Bactrites GRIMES SANDSTONE This formation is composed principally of even layers of sand- stone from six inches to three feet thick, some of which are rather soft and shaly, while others are hard and calcareous. The aggregate thickness is not far from fifty feet. It appears on the next quadrangle toward the east in the Grimes gully at Naples, where it contains a small brachiopod fauna allied to the Ithaca fauna and other forms not known elsewhere. Though these sandstones outcrop in many places on the Way- land quadrangle there are very few good exposures of the entire formation. The entire section is shown in the Calabogue ravine below the lower bridge in the village of Conesus. The sandstones are quite barren of fossils except at the top, where a 14 to 16 inch layer is very hard, calcareous and concretionary and contains large irregularly shaped concretions so frequently as to almost form a continuous layer. It bears a close resemblance to a stratum in this horizon in Tannery gully, Naples, and like that one, contains brachiopod shells quite abundantly, but mostly in so fragmentary condition as to preclude identification. Entire valves of a small Rhipidomella and Productella spinulico^ta occur and loose spines of a larger Productella are abundant. Fragments of Liorhynchus may also be recognized. The Grimes sandstones may be seen at the Delaware, Lacka- wanna & Western Railroad culvert in the Culberson gully three and one-half miles north of Dansville, in other ravines and quarries in the east side of the Canaseraga valley, and on the west side at the mouth of the Bradner creek ravine half a mile northwest of Woodville. 22 NEW YORK STATE MUSEUM GARDEAU FLAGS AND SHALE Light bluish gray sandstones and flags separated by beds of blue, olive or black shales succeed the Grimes sandstone for about 500 feet. In general stratigraphy this formation is much like the Hatch shale and flags, but many of the sandstones and some of the shale beds are thicker than are seen in that formation. It is the surface rock over a large area on these quadrangles, the drift cover of which, except in a few localities, is quite thin, and field outcrops are frequent. Almost innumerable ravines and small gul- lies on the hillsides show rock sections e:nbracing some part of the Gardeau beds. Among the best exposures on these quadrangles are : in Reynold's gulf, three miles north of Springwater ; along Calabogue creek- above the mill at Conesus ; the Culberson ravine above the railroad ; the Bradner creek ravine north of Woodville ; and at Stones Falls and Stony brook glen south of Dansville. Fossils are rare, but a few brachiopods known in the Ithaca fauna occur in some of the sandstones, and a few lamellibranchs and cephalopods common in the Cashaqua shales are found in soft shales, especially in the upper part of the formation. The following is a partial list of the species occurring in the Gar- deau beds : Manticoceras oxy Clarke Palaeotrochus praecursor Clarke Grammysia elliptica Hall Leptodesma robustum Hall Productella lachrymosa Hall P. spinulicosta Hall Ambocoelia umbonata (Conrad) Atrypa hystrix Hall Orthothetes chemungensis Conrad Liorhynchus mesacostalis Hall Hydnoceras tuberosum Conrad Aulopora sp. • Crinoid stems NUNDA SANDSTONE (Portage sandstone of early reports) A heavy band of light bluish gray sandstone succeeds the Gar- deau flags in central New York. It is a strongly marked feature of the stratigraphy of the region and is of considerable economic value as the source of fine building stone. GEOLOGY OF THE HONEOYE-WAYLAND QUADRANGLES 23 The formation is nearly 200 feet thick in the Genesee river sec- tion, but thins out toward the west and barely reaches Lake Erie. It is less homogeneous toward the east, some parts becoming shaly, but it is traceable to the Seneca lake valley. On the Genesee river and farther west fossils, except plant re- mains, are extremely rare, but on the Wayland quadrangle and eastward, there are found lenticular masses of crinoidal limestone that contain brachiopods and other fossils in large numbers. Except in the southern part of the Wayland quadrangle, the position of these sandstones is too high to permit of good ex- posures, but they are well displayed for nearly a mile along the Pittsburg, Shawmut & Northern Railroad two miles southeast of Perkinsville. Extensive quarries on the hill east of Dansville are in these beds, and they have also been quarried on the south face of the hill one and one-half miles north of Perkinsville. Blocks from a fossiliferous lentil at the south end of the hill four miles east of Wayland have been utilized as firestone in that vicinity. Calcareous slabs from this lens, or possibly another one, lie on the north face of the hill one and one-half miles southeast of Wayland. The fossils contained in these lentils have not been listed, except in the case of the large one on High point on the Naples quad- rangle three miles east of this quadrangle, from which 32 species have been obtained. For list, see State Museum Bulletin 63. WISCOY BEDS About 200 feet of light and dark shales and soft sandstones that contain a fauna bearing some resemblance to that of the normal Portage and on that account have been considered as a separate formation, succeed the Nunda sandstone on the Genesee river. Though acquiring an increase of sandy material and appearing mainly as a bed of rather soft -olive sandstone, on the Wayland quadrangle this formation is readily distinguished from the harder, lighter colored and usually more fossiliferous sandstones and harder shales of the normal Chemung beds by which it is overlain. There is a small exposure of Wiscoy beds by the side of the Pittsburg & Shawmut Railroad where it crosses the south line of the quadrangle, and a more extensive one from two miles south of Patchenville to the south line of the quadrangle. Crinoid stems, small brachiopods and a small Orthoceras occur here. The large cephalopod Manticoceras oxy Clarke appears occasionally in these beds. • 24 NEW YORK STATE MUSEUM 9 With the increase of sand in the sedimentation toward the east, a few brachiopods which are not found at Wiscoy appear. CHEMUNG SHALE AND SANDSTONE About 450 feet of the lower beds of this formation compose the surface rock on the high land in the extreme southern part of the Wayland quadrangle. In lithologic character they are not materially different from the Gardeau beds, except that the sand- stones are lighter colored and more micaceous. Fossils are rare in the lower 300 feet but are in very great abundance in the higher sandstones exposed on this quadrangle. These may be seen to good advantage along the roadside three- fourths of a mile northeast of Loon lake, where the rock is crowded with large brachiopods. Hydnoceras nodosum Hall occurs here also. The rock lies near the surface over this region and small field exposures are frequent, but there are no extensive outcrops. DIP The aVerage dip of the base of the Onondaga limestone be- tween Honeoye Falls and the salt shaft at Livonia is about 33 feet per mile toward the south. On an east and west line, though made variable by frequent undulations of the strata, this lime- stone is on the whole nearly level. As all of the formations above the Onondaga up to the Wis- coy shale, except the Stafford limestone and the Rhinestreet black shale, thin out more or less rapidly toward the west, the dip in that direction varies also with the contact line used as a base, but is nowhere appreciable except on careful measurement. The deep and narrow valleys partly occupied by Conesus, Hemlock and Honeoye lakes are blocked at the south ends by enormous beds of gravel, sand and clay which compose a part of the great moraine of the second glacial epoch. The areas intervening be- tween the lakes and the moraine are level beds of rich alluvium. The Genesee river valley in the northwest corner of the Honeoye quadrangle; the Canaseraga valley near Dansville; the bed of a small lake near Wayland and another at South Lima, are of similar character. A striking exhibition of the force of glacial action occurs in a small amphitheatrical valley of Stony brook at Five Corners, four miles west of Honeoye Falls. The bed rock, Bertie waterlime, is GEOLOGY OF THE HONEOYE-WAYLAND QUADRANGLES 25 but slightly exposed, but a very large quantity of Lockport dolo- mite has been transported southward a distance of al/ least twelve miles and deposited here. The sloping bank on the east side of the little valley is almost covered by blocks of the brown scraggly rock, some of which are twelve to fifteen feet across and six to eight feet thick. They lie so close together that they present the appearance of a broken escarpment, extending toward the north for 60 to 70 rods. Large blocks of the dolomite are common in this vicinity and a morainic mass of this rock covers several acres half a mile west of this locality, but is mostly in smalkr blocks.
