TROW DIRECTORY PRINTING AND BOOKBINDING COMPANY NEW YORK ^cioft Library PREFACE-DEDICATION Co A. M. C. After the making of Eden came a serpent, and after the gorgeous furnishing of the world, a human being. Why the existence of the de- stroyers ? What monstrous folly, think you, ever led Nature to create her one great enemy — man ! Before his coming security may have been ; but how soon she learned the meaning of fear when this new (Edipus of her brood was brought forth ! And how instinctively she taught the fear of him to the rest of her chil- dren ! To-day, after centuries of association, every bird and beast and creeping thing — the wolf in the forest, the antelope on the plain, the wild fowl in the sedge — fly from his ap- proach. They know his civilization means their destruction. Even the grizzly, secure in the chaparral of his mountain home, flinches as he crosses the white man^s trail. The boot mark VIU PREFACE-DEDICATION in the dust smells of blood and iron. The great annihilator has come and fear travels with him. " Familiar facts/^ you will say. Yes ; and not unfamiliar the knowledge that with the coming of civilization the grasses and the wild flowers perish, the forest falls and its place is taken by brambles, the mountains are blasted in the search for minerals, the plains are broken by the plow and the soil is gradually washed into the rivers. Last of all, when the forests have gone the rains cease falling, the streams dry up, the ground parches and yields no life, and the artificial desert — the desert made by the tramp of human feet — begins to show itself. Yes ; everyone must have cast a backward glance and seen Nature^s beauties beaten to ashes under the successive marches of civilization. The older portions of the earth show their desolation plainly enough, and the ascending smoke and dust of the ruin have even tainted the air and dimmed the sunlight. Indeed, I am not speaking figuratively or extravagantly. We have often heard of " Sunny Italy'' or the ^^ clear light'' of Egypt, but be- lieve me there is no sunlight there compared with that which falls upon the upper peaks of PREFACE-DEDICATION IX the Sierra Madre or the uninhabitable wastes of the Colorado Desert. Pure sunlight requires for its existence pure air, and the Old World has little of it left. When you are in Eome again and stand upon that hill where all good roman- ticists go at sunset, look out and notice how dense is the atmosphere between you and St. Peter^s dome. That same thick air is all over Europe, all around the Mediterranean, even over in Mesopotamia and by the banks of the Ganges. It has been breathed and burned and battle-smoked for ten thousand years. Eide up and over the high table-lands of Montana — one can still ride there for days without seeing a trace of humanity — and how clear and scentless, how absolutely intangible that sky-blown sun- shot atmosphere ! You breathe it without feel- ing it, you see through it a hundred miles and the picture is not blurred by it. It is just so with Nature^s color. True enough, there is much rich color at Venice, at Cairo, at Constantinople. Its beauty need not be denied ; and yet it is an artificial, a chemical color, caused by the disintegration of matter — the decay of stone, wood, and iron torn from the neighboring mountains. It is Nature after a poor fashion — Nature subordinated to the will PEEFACE-DEDICATION of man. Once more ride over the enchanted mesas of Arizona at sunrise or at sunset, with the ragged mountains of Mexico to the south of you and the broken spurs of the great sierra round about you ; and all the glory of the old shall be as nothing to the gold and purple and burning crimson of this new world. You will not be surprised then if, in speaking of desert, mesa and mountain I once more take you far beyond the wire fence of civilization to those places (unhappily few now) where the trail is unbroken and the mountain peak un- blazed. I was never over-fond of park and garden nature-study. If we would know the great truths we must seek them at the source. The sandy wastes, the arid lands, the porphyry mountain peaks may be thought profitless places for pilgrimages ; but how often have you and I, and that one we both loved so much, found beauty in neglected marshes, in wintry forests, and in barren hill-sides ! The love of Nature is after all an acquired taste. One be- gins by admiring the Hudson-Kiver landscape and ends by loving the desolation of Sahara. Just why or how the change would be difficult to explain. You cannot always dissect a taste or a passion. Nor can you pin Nature to a PREFACE-DEDICATION XI board and chart her beauties with square and compasses. One can give his impression and but little more. Perhaps I can tell you some- thing of what I have seen in these two years of wandering; but I shall never be able to tell you the grandeur of these mountains, nor the glory of color that wraps the burning sands at their feet. We shoot arrows at the sun in vain ; yet still we shoot. And so it is that my book is only an excuse for talking about the beautiful things in this desert world that stretches down the Pacific Coast, and across Arizona and Sonora. The desert has gone a-begging for a word of praise these many years. It never had a sacred poet ; it has in me only a lover. But I trust that you, and the nature-loving public you represent, will accept this record of the Colorado and the Mojave as at least truthful. Given the facts perhaps the poet with his fancies will come hereafter. John C. Van Dyke. La Nokia Verde February, 1901. CONTENTS Chapter I.

For days I have been watch- ing them change color at sunset — watching the canyons shift into great slashes of blue and purple shadow, and the ridges flame with edg- ings of glittering fire. They are lonesome look- ing mountains lying oif there by themselves on the plain, so still, so barren, so blazing hot under the sun. Forsaken of their kind, one might not inappropriately call them the ^^ Lost Mountains '^ — the surviving remnant no doubt of some noble range that long centuries ago was beaten by wind and rain into desert sand. And yet before one gets to them they may prove quite formidable heights, with precipitous sides and unsurmountable tops. Who knows ? Not those with whom I am stopping, for they have 1 Desert moimtcnns. THE DESERT Unknown ranges. Early morning on the desert. Air illu- tions. not been there. They do not even know the name of them. The Papagoes leave them alone because there is no game in them. Evidently they are considered unimportant hills, no- body^s hills, no man^s range ; but nevertheless I am off for them in the morning at daylight. I ride away through the thin mesquite and the little adobe ranch house is soon lost to view. The morning is still and perfectly clear. The stars have gone out, the moon is looking pale, the deep blue is warming, the sky is lightening with the coming day. How cool and crystalline the air ! In a few hours the great plain will be almost like a fiery furnace under the rays of the summer sun, but now it is chilly. And in a few hours there will be rings and bands and scarves of heat set wavering across the waste upon the opalescent wings of the mirage ; but now the air is so clear that one can see the breaks in the rocky face of the mountain range, though it is fully twenty miles away. It may be further. Who of the desert has not spent his day riding at a mountain and never even reaching its base ? This is a land of illu- sions and thin air. The vision is so cleared at times that the truth itself is deceptive. But I shall ride on for several hours. If, by twelve THE APPEOACH 3 o^clock, the foot hills are not reached, I shall turn back. The summer heat has withered everything except the mesquite, the palo verde,* the grease wood, and the various cacti. Under foot there is a little dry grass, but more often patches of bare gravel and sand rolled in shal- low beds that course toward the large valleys. In the draws and flat places the fine sand lies thicker, is tossed in wave forms by the wind, and banked high against clumps of cholla or prickly pear. In the wash-outs and over the cut banks of the arroyos it is sometimes heaped in mounds and crests like driven snow. It blows here along the boundary line between Arizona and Sonora almost every day ; and the tailing of the sands behind the bushes shows that the prevailing winds are from the Gulf region. A cool wind ? Yes, but only by com- parison with the north wind. When you feel it on your face you may think it the breath of some distant volcano. How pale -blue the Lost Mountains look under the growing light. I am watching their edges develop into broken barriers of rock, and * The use of Spanish names is compulsory. There are no English equivalents. Sand forms in the valleys. Winds of the desert THE BESEET Sun shafts. The beauty of sunlight. even as I watch the tallest tower of all is struck with a bright fawn color. It is the high point to catch the first shaft of the sun. Quickly the light spreads downward until the whole ridge is tinged by it, and the abrupt sides of porphyry begin to glow under it. It is not long before great shafts of light alternating with shadow stretch down the plain ahead of me. The sun is streaming through the tops of the eastern mountains and the sharp pointed pinnacles are cutting shadows in the broad beam of light. That beam of light ! Was there ever any- thing so beautiful ! How it flashes its color through shadow, how it gilds the tops of the mountains and gleams white on the dunes of the desert ! In any land what is there more glorious than sunlight ! Even here in the desert, where it falls fierce and hot as a rain of meteors, it is the one supreme beauty to which all things pay allegiance. The beast and the bird are not too fond of its heat and as soon as the sun is high in the heavens they seek cover in the canyons ; but for all that the chief glory of the desert is its broad blaze of omnipresent light. Yes, there is animal and bird life here though it is not always apparent unless you look for it. THE APPROACH Wrens and linnets are building nests in the cholla, and finches are singing from the top of the sahnaro.* There are plenty of reptiles, rabbits and ground squirrels quietly slipping out of your way ; and now that the sun is up you can see a long sun-burned slant-of-hair trotting up yonder divide and casting an appre- hensive head from side to side as he moves off. It is not often that the old gray wolf shows himself to the traveller. He is usually up in the mountains before sunrise. And seldom now does one see the desert antelope along the mesas, and yet off to the south you can see patches of white that come and go almost like flashing mirrors in the sun. They are stragglers from some band that have drifted up from cen- tral Sonora. No; they are not far away. A little mirage is already forming over that portion of the mesa and makes them look more distant than they are in reality. You can be deceived on the desert by the nearness of things quite as often as by their remoteness. These desert mountains have a fashion of ap- pearing distant until you are almost up to them. Then they seem to give up the game of decep- tion and come out of their hiding-places. It is ♦ Properly Saguaro. Desert life. Antelope. The Lost Mountains. THE DESERT Mountain walls. The ascent. Deer trails. just SO with the mountains toward which I am riding. After several hours they seem to rise up suddenly in front of me and I am at their base. They are not high — perhaps fifteen hundred feet. The side near me is precipitous rock, weather-stained to a reddish-black. A ride around the bases discloses an almost com- plete perpendicular wall, slanting off half way down the sides into sloping beds of bowlders that have been shaken loose from the upper strata. A huge cleft in the western side — half barranca half canyon — seems to suggest a way to the summit. The walking up the mountain is not the best in the world. It is over splintered rock, step- ping from stone to stone, creeping along the backbone of bowlders, and worrying over rows of granite blocks. Presently the course seems to slip into a diagonal — a winding up and around the mountain — and ahead of me the stones begin to look peculiar, almost familiar. There seems to be a trail over the ledges and through the broken blocks ; but what should make a trail up that deserted mountain ? Mule-deer travelling toward the summit to lie down in the heat of the day ? It is possible. The track of a band of deer soon becomes a THE APPROACH beaten path, and animals are just as fond of a good path as humanity. By a strange coin- cidence at this very moment the sharp-toed print of a deer^s hoof appears in the ground before me. But it looks a little odd. The im- pression is so clear cut that I stoop to examine it. It is with no little astonishment that I find it sunk in stone instead of earth — petrified in rock and overrun with silica. The bare sug- gestion gives one pause. How many thousands of years ago was that impression stamped upon the stone ? By what strange chance has it survived destruction ? And while it remains quite perfect to-day — the vagrant hoof-mark of a desert deer — what has become of the once carefully guarded footprints of the Sargons, the Pharaohs and the Caesars ? With what contempt Nature sometimes plans the survival of the least fit, and breaks the conqueror on his shield ! Further up the mountain the deer-trail theory is abandoned — at least so far as recent times are concerned. The stones are worn too smooth, the larger ones have been pushed aside by something more intelligent than a mule-deer^s hoof ; and in one place the trail seems to have been built up on the descending side. There is Footprints, The stone path. THE DESEET FoUovnng the trail. Defensive walls. The summit. not the slightest evidence, either by rub upon the rocks, or overturned stones, or scrape in the gravel, that any living thing has passed up this pathway for many years ; and yet the trail is a distinct line of lighter colored stone stretch- ing ahead of me. It is a path worn in the rocks, and there is no grass or vine or weed to obliterate it. It leads on and up to the saddle of the mountain. There is a crevasse or chasm breaking through this saddle which might have been bridged at one time with mesquite trunks, but is now to be leaped if one would reach the summit. It is narrow only in one place and this is just where the trail happens to run. Across it, on the upper side, there is a horse- shoe shaped enclosure of stone. It is only a few feet in diameter, and the upper layers of stone have fallen ; but the little wall still stands as high as one^s waist. Could this have been a sentinel box used to guard the passage of the trail at this place ? Higher and still higher until at last the mountain broadens into a flat top. I am so eager to gain the height and am expecting so much that at first I overlook what is before me. Gradually I make out a long parapet of loose stone on the trail side of the mountain which THE APPROACH 9 joins on to steep cliffs on the other sides. A conclusion is instantly jumped at, for the im- agination will not make haste slowly under such circumstances. These are the ruins of a once fortified camp. I wander about the flat top of the mountain and slowly there grows into recognizable form a great rectangle enclosed by large stones placed about two feet apart. There is no doubt about the square and in one corner of it there seems an elevated mound covered with high-piled stones that would indicate a place for burials. But not a trace of pottery or arrow-heads ; and about the stones only faint signs of fire which might have come from volcanic action as readily as from domestic hearths. Upon the side of one of the large rocks are some characters in red ochre ; and on the ground near a pot-hole in the rock, something that the imagination might torture into a rude pestle for grinding maize. The traces of human activity are slight. Nat- ure has been wearing them away and reclaim- ing her own on the mountain top. Grease wood is growing where once a floor was beaten hard as iron by human feet ; out of the burial mound rises a giant sahuaro whose branching TheforHfied camp. Nature's reclamO' tions. 10 THE DESERT Mountain dwellers. Invading hosts. arms give the look of the cross ; and beside the sahuaro rests a tall yucca with four feet of clustering bellflowers swinging from its top. And who were they who built these stone walls, these primitive entrenchments ? When and where did they come from and what brought them here ? The hands that executed this rough work were certainly untrained. Indians ? Very likely. Perhaps some small band that had taken up a natural defence in the mountains because too feeble in numbers to fight in the open. Here from this lookout they could watch the country for a hundred miles around. Here the scouts could see far away the thin string of foemen winding snake-like over the ridges of the desert, could see them grow in size and count their numbers, could look down upon them at the foot of the mountain and yell back defiance to the challenge coming up the steep sides. Brave indeed the invaders that would pluck the eagles from that eerie nest ! Climb- ing a hill against a shower of arrows, spears, and bowlders is to fight at a terrible disad- vantage. Starve them out ? Yes ; but the ones at the bottom would starve as quickly as those at the top. Cut off their water supply ? Yes ; but THE APPKOACH 11 where did either besieged or besieger get water? If there was ever a spring in the mountain it long ago dried np, for there is no trace of it to- day. Possibly the mountain-dwellers knew of some arroyo where by digging in the sand they could get water. And possibly they carried it in ollas up the stone trail to their mountain home where they stored it in the rocks against the wrath of a siege to come. No doubt they took thought for trouble, and being native to the desert they could stand privation better than their enemies. How long ago did that aboriginal band come trailing over these trackless deserts to find and make a home in a barren mountain standing in a bed of sand ? Who can tell ? A geologist might make the remains of their fort an il- lustration of the Stone Age and talk of un- known centuries ; an iconoclast might claim that it was merely a Mexican corral built to hide stolen horses ; but a plain person of the southwest would say that it was an old Indian camp. The builders of the fortification and the rectangle worked with stone because there was no other material. The man of the Stone Age exists to-day contemporary with civilized man. Possibly he always did. And it may be that Water and food sup- plies. Theah
