APPENDIX D THE VALLEY OF THE UPPER YELLOWSTONE By C. W. COOK The country around the headwaters of the Yellowstone River, although frequently visited by prospectors and mountain men, is still to the world of letters a veritable terra incognita. Environed by mountain chains that are covered by a dense growth of timber, making all approaches to it seem difficult, it has no regularly traveled route, and no party of emigrants on their way to the Pacific slope have ever passed through it; nor has any expedition under the patronage of the Government yet attempted to penetrate its fastnesses. The hardy prospectors, searching in this region for new "diggings," have hitherto failed to find gold in paying quantities, but have always returned to repeat the tales of wonderful waterfalls a thousand feet in height, of innumerable hot springs of surprising magnitude, and of vast tracts of country covered with the scoria of volcanoessome of which were reported to be in active operation. Owing to the fact that this class of men had gained a reputation for indulging in flights of fancy when recounting their adventures, these reports were received with considerable incredulity, until it was noticed that, however much the accounts of different parties differed in detail, there was a marked coincidence in the descriptions of some of the most prominent features of the country. In 1867, an exploring expedition from Virginia City, Montana Territory, was talked of; but for some unknown reasonprobably for the want of a sufficient number to engage in itit was abandoned. The next year another was planned, which ended like the firstin talk. Early in the summer of 1869 the newspapers throughout the Territory announced that a party of citizens from Helena, Virginia City, and Bozeman, accompanied by some of the officers stationed at Fort Ellis, with an escort of soldiers, would leave Bozeman about the 5th of September for the Yellowstone country, with the intention of making a thorough examination of all the wonders with which that region was said to abound. The party was expected to be limited in numbers and to be composed of some of the most prominent men in the Territory; and the writer felt extremely flattered when his earnest request to have his name added to the list was granted. He joined with two personal friends in getting an outfit and then waited patiently for the other members of the party to perfect their arrangements. About a month before the day fixed for starting, some of the members began to discover that pressing business engagements would prevent their going. Then came news from Fort Ellis that, owing to some changes made in the disposition of troops stationed in the Territory, the military portion of the party would be unable to join the expedition; and our party, which had now dwindled down to 10 or 12 persons, thinking it would be unsafe for so small a number to venture where there was a strong probability of meeting with hostile Indians, also abandoned the undertaking. But the writer and his two friends before mentioned believing that the dangers to be encountered had been magnified and, trusting by vigilance and good luck to avoid them, resolved to attempt the journey at all hazards. We provided ourselves with 5 horses, 3 of them for the saddle and the other 2 for carrying our cooking utensils, ammunition, fishing tackle, blankets and buffalo robes, a pick and pan, a shovel, an ax, and provisions necessary for a six weeks' trip. We were all well armed with repeating rifles, Colt's six shooters, and sheath knives, and had besides a double-barreled shotgun for small game. We also had a good field glass, a pocket compass, and a thermometer. On the 6th of September we started from Diamond City, a mining town on a small tributary of the Missouri River 40 miles east of Helena. Our second day's journey brought us to Gallatin City, at the "three forks" of the Missouri. From Gallatin City a ride of three hours brought us to Hamilton, a post town situated near the center of the Gallatin Valley, where we camped for the night. From Hamilton to Bozeman, a distance of 18 miles, our route lay through a beautiful farming country, where generous stacks of grain or wide fields covered with golden sheaves indicated the propriety of calling this valley the Genesee of Montana. Bozeman is a thriving frontier town, pleasantly located in the eastern part of the Gallatin Valley. Bozeman Pass, the lowest pass in the divide between the waters of the Yellowstone and the Missouri Rivers, has been surveyed as the proposed route for the Northern Pacific Railroad. Two and one-half miles from Bozeman we passed Fort Ellis, soon after leaving which we took a trail leading up a creek which is one of the tributaries of the East Gallatin, and in a short time found ourselves traversing a deep ravine, bounded on the left by a perpendicular wall of limestone a thousand feet in height, while on the right the mountains rose in irregular steps or terraces, covered with a dense growth of spruce. In some places the mass of dark green foliage was unbroken from base to summit, at others it was relieved by beetling cliffs of fantastic shape, so characteristic of the limestone formation. On one of the highest points stood a huge rock that bore a strong resemblance to an old castle; rampant and bulwark were slowly yielding to the ravages of time, but the stout old turret stood out in bold relief against the sky, with every embrasure as perfect in outline as though but a day ago it had been built by the hand of man. We could almost imagine that it was the stronghold of some baron of feudal times and that we were his retainers returning laden with the spoils of a successful foray. As we approached the summit, the timber appeared only in patches and the hills on either hand were less abrupt and covered with a luxuriant growth of bunch grass, which affords fine pasturage for the numerous herds of antelope which roam there. Immediately after crossing the divide we struck the head of Trail Creek and followed it down 6 or 7 miles in an easterly direction to where it debouched from the foothills into the valley of the Yellowstone. Here we turned in a southerly direction over a low, rolling plateau covered with prickly pear, through which our horses gingerly picked their way, and arrived at the river about sunset. This valley is about 25 miles long and varies in width from 1 to 5 miles; at the foot of it the mountains close in on both sides, forming a canyon, below which is the Yellowstone Valley proper. We pushed on up the valley, following the general course of the river as well as we could, but frequently making short detours through the foothills, to avoid the deep ravines and places where the hills terminated abruptly at the water's edge. On the eighth day out we encountered a band of Indianswho, however, proved to be Tonkeys, or Sheepeaters, and friendly; the discovery of their character relieved our minds of apprehension, and we conversed with them as well as their limited knowledge of English and ours of pantomime would permit. For several hours after leaving them we traveled over a high rolling table-land, diversified by sparkling lakes, picturesque rocks, and beautiful groves of timber. Two or three miles to our left we could see the deep gorge which the river, flowing westward, had cut through the mountains. The river soon after resumed its northern course; and from this point to the falls, a distance of 25 or 30 miles, it is believed to flow through one continuous canyon, through which no one has ever been able to pass. At this point we left the main river, intending to follow up the east branch for one day, then to turn in a southwest course and endeavor to strike the river again near the falls. After going a short distance we encountered a canyon about 3 miles in length, and while passing around it we caught a glimpse of scenery so grand and striking that we decided to stop for a day or two and give it a more extended examination. We picked our way to a timbered point about midway of the canyon, and found ourselves upon the verge of an overhanging cliff at least 700 feet in height. The opposite bluff was about on a level with the place where we were standing; and it maintained this height for a mile up the river, but gradually sloped away toward the foot of the canyon. The upper half presented an unbroken face, with here and there a reentering angle, but everywhere maintained its perpendicularity; the lower half was composed of the debris that had fallen from the wall. But the most singular feature was the formation of the perpendicular wall. At the top there was a stratum of basalt from 30 to 40 feet thick standing in hexagonal columns; beneath that a bed of conglomerate 80 feet thick, composed of washed gravel and bowlders; then another stratum of columnar basalt of about half the thickness of the first; and lastly what appeared to be a bed of coarse sandstone. A short distance above us, rising from the bed of the river, stood a monument or pyramid of conglomerate, circular in form, which we estimated to be 40 feet in diameter at the base and 300 feet high, diminishing in size in a true taper to its top, which was not more than 3 feet across. It was so slender that it looked as if one man could topple it over. How it was formed I leave others to conjecture. We could see the river for nearly the whole distance through the canyonnow dashing over some miniature cataract, now fretting against huge bowlders that seemed to have been hurled by some giant hand to stay its progress, and anon circling in quiet eddies beneath the dark shadows of some projecting rock. The water was so transparent that we could see the bottom from where we were standing, and it had that peculiar liquid emerald tinge so characteristic of our mountain streams. Half a mile down the river, and near the foot of the bluff, was a chalky looking bank, from which steam and smoke were rising; and on repairing to the spot we found a vast number of hot sulphur springs. The steam was issuing from every crevice and hole in the rocks; and, being highly impregnated with sulphur, it threw off sulphuretted hydrogen, making a stench that was very unpleasant. All the crevices were lined with beautiful crystals of sulphur, as delicate as frostwork. At some former period not far distant there must have been a volcanic eruption here. Much of the scoria and ashes which were then thrown out has been carried off by the river; but enough still remains to form a bar 75 or 100 feet in depth. Smoke was still issuing from the rocks in one place, from which a considerable amount of lava had been discharged within a few days or weeks at farthest. While we were standing by, several gallons of a black liquid ran down and hardened upon the rocks; we broke some of this off and brought it away, and it proved to be sulphur, pure enough to burn readily when ignited. September 18the twelfth day outwe found that ice had formed one-fourth of an inch thick during the night, and 6 inches of snow had fallen. The situation began to look a little disagreeable; but the next day was bright and clear, with promise of warm weather again in a few days, Resuming our journey, we soon saw the serrated peaks of the Big Horn Range glistening like burnished silver in the sunlight, and, overtowering them in the dim distance, the Wind River Mountains seemed to blend with the few fleecy clouds that skirted their tops; while in the opposite direction, in contrast to the barren snow-capped peaks behind us, as far as the eye could reach, mountain and valley were covered with timber, whose dark green foliage deepened in hue as it receded, till it terminated at the horizon in a boundless black forest. Taking our bearings as well as we could, we shaped our course in the direction in which we supposed the falls to be. The next day (September 20) we came to a gentle declivity at the head of a shallow ravine, from which steam rose in a hundred columns and united in a cloud so dense as to obscure the sun. In some places it spurted from the rocks in jets not larger than a pipestem; in others it curled gracefully up from the surface of boiling pools from 5 to 15 feet in diameter. In some springs the water was clear and transparent; others contained so much sulphur that they looked like pots of boiling yellow paint. One of the largest was as black as ink. Near this was a fissure in the rocks, several rods long and 2 feet across in the widest place at the surface, but enlarging as it descended. We could not see down to any great depth, on account of the steam; but the ground echoed beneath our tread with a hollow sound, and we could hear the waters surging below, sending up a dull, resonant roar like the break of the ocean surf into a cave. At these springs but little water was discharged at the surface, it seeming to pass off by some subterranean passage. About half a mile down the ravine the springs broke out again. Here they were in groups, spreading out over several acres of ground. One of these groupsa collection of mud springs of various colors, situated one above the other on the left slope of the ravinewe christened "The Chemical Works." The mud, as it was discharged from the lower side, gave each spring the form of a basin or pool. At the bottom of the slope was a vat, 10 by 30 feet, where all the ingredients from the springs above were united in a greenish-yellow compound of the consistency of white lead. Three miles farther on we found more hot springs along the sides of a deep ravine, at the bottom of which flowed a creek 20 feet wide. Near the bank of the creek, through an aperture 4 inches in diameter, a column of steam rushed with a deafening roar, with such force that it maintained its size for 40 feet in the air, then spread out and rolled away in a great cloud toward the heavens. We found here inexhaustible beds of sulphur and saltpeter. Alum was also abundant; a small pond in the vicinity, some 300 yards long and half as wide, contained as much alum as it could hold in solution, and the mud along the shore was white with the same substance crystallized by evaporation. On September 21 a pleasant ride of 18 miles over an undulating country brought us to the great canyon 2 miles below the falls; but there being no grass convenient, we passed on up the river to a point half a mile above the upper falls and camped on a narrow flat close to the river bank. We spent the next day at the fallsa day that was a succession of surprisesand we returned to camp realizing as we had never done before how utterly insignificant are man's mightiest efforts when compared with the fulfillment of Omnipotent will. Language is entirely inadequate to convey a just conception of the awful grandeur and sublimity of this masterpiece of nature's handiwork; and in my brief description I shall confine myself to bare facts. Above our camp the river is about 150 yards wide and glides smoothly along between gently sloping banks, but just below the hills crowd in on either side, forcing the water into a narrow channel, through which it hurries with increasing speed, until, rushing through a chute 60 feet wide, it falls in an unbroken sheet over a precipice 115 feet in height. It widens out again, flows with steady course for half a mile between steep timbered bluffs 400 feet high, and again narrowing in till it is not more than 75 feet wide, it makes the final fearful leap of 350 feet. The ragged edges of the precipice tear the water into a thousand streamsall united together, and yet apparently separatechanging it to the appearance of molten silver; the outer ones decrease in size as they increase in velocity, curl outward, and break into mist long before they reach the bottom. This cloud of mist conceals the river for 200 yards, but it dashes out from beneath the rainbow arch that spans the chasm, and thence, rushing over a succession of rapids and cascades, it vanishes at last, where a sudden turn of the river seems to bring the two walls of the canyon together. Below the falls the hills gradually increase in height for 2 miles, where they assume the proportions of mountains. Here the canyon is at least 1,500 feet deep, with an average width of twice that distance at the top. For one-third of the distance downwards the sides are perpendicular; from thence running down to the river in steep ridges crowned by rocks of the most grotesque form and color; and it required no stretch of the imagination to picture fortresses, castles, watchtowers, and other ancient structures of every conceivable shape. In several places near the bottom steam issued from the rocks; and judging from the indications there were at some former period hot springs or steam jets of immense size all along the wall. The next day we resumed our journey, traversing the northern slope of a high plateau between the Yellowstone and Snake Rivers. Unlike the dashing mountain stream we had thus far followed, the Yellowstone was in this part of its course wide and deep, flowing with a gentle current along the foot of low hills or meandering in graceful curves through broad and grassy meadows. Some 12 miles from the falls we came to a collection of hot springs that deserve more than a passing notice. These, like the most we saw, were situated upon a hillside; and as we approached them we could see the steam rising in puffs at regular intervals of 15 or 20 seconds, accompanied by dull explosions, which could be heard half a mile away, sounding like the discharge of a blast underground. These explosions came from a large cave that ran back under the hill, from which mud had been discharged in such quantities as to form a heavy embankment 20 feet higher than the floor of the cave, which prevented the mud from flowing off; but the escaping steam had kept a hole some 20 feet in diameter open up through the mud in front of the entrance to the cave. The cave seemed nearly filled with mud and the steam rushed out with such volume and force as to lift the whole mass up against the roof and dash it out into the open space in front; and then, as the cloud of steam lifted, we could see the mud settling back in turbid waves into the cavern again. Three hundred yards from the mud cave was another that discharged pure water; the entrance to it was in the form of a perfect arch, 7 feet in height and 5 feet in width. A short distance below these caves were several large sulphur springs, the most remarkable of which was a shallow pool, 75 feet in diameter, in which clear water on one side and yellow mud on the other were gently boiling without mingling. September 24 we arrived at Yellowstone Lake, about 20 miles from the falls. The main body of this beautiful sheet of water is 10 miles wide from east to west, and 16 miles long from north to south; but at the south end it puts out two arms, one to the southeast and the other to the southwest, making the entire length of the lake about 30 miles. Its shoreswhether gently sloping mountains, bold promontories, low necks, or level prairiesare everywhere covered with timber. The lake has three small islands, which are also heavily timbered. The outlet is at the northwest extremity. The lake abounds with trout, and the shallow water in its coves affords feeding ground for thousands of wild ducks, geese, pelicans, and swans. We ascended to the head of the lake and remained in its vicinity for several days, resting ourselves and our horses and viewing the many objects of interest and wonder. Among these were springs differing from any we had previously seen. They were situated along the shore for a distance of 2 miles, extending back from it about 500 yards and into the lake perhaps as many feet The ground in many places gradually sloped down to the water's edge, while in others the white chalky cliffs rose 15 feet highthe waves having worn the rock away at the base, leaving the upper portion projecting over in some places 20 feet. There were several hundred springs here, varying in size from miniature fountains to pools or wells 75 feet in diameter and of great depth; the water had a pale violet tinge, and was very clear, enabling us to discern small objects 50 or 60 feet below the surface, in some of these, vast openings led off at the side; and as the slanting rays of the sun lit up these deep caverns we could see the rocks hanging from their roofs, their water-worn sides and rocky floors, almost as plainly as if we had been traversing their silent chambers. These springs were intermittent, flowing or boiling at irregular intervals. The greater portion of them were perfectly quiet while we were there, although nearly all gave unmistakable evidence of frequent activity. Some of them would quietly settle for 10 feet, while another would as quietly rise until it overflowed its banks, and send a torrent of hot water sweeping down to the lake. At the same time one near at hand would send up a sparking jet of water 10 or 12 feet high, which would fail back into its basin and then perhaps instantly stop boiling and quietly settle into the earth, or suddenly rise and discharge its waters in every direction over the rim; while another, as if wishing to attract our wondering gaze, would throw up a cone 6 feet in diameter and 8 feet high, with a loud roar. These changes, each one of which would possess some new feature, were constantly going on; sometimes they would occur within the space of a few minutes, and again hours would elapse before any change could be noted. At the water's edge, along the lake shore, there were several mounds of solid stone, on the top of each of which was a small basin with a perforated bottom; these also overflowed at times and the hot water trickled down on every side. Thus, by the slow process of precipitation, through the countless lapse of ages, these stone monuments have been formed. A small cluster of mud springs near by claimed our attention. They were like hollow truncated cones and oblong mounds 3 or 4 feet in height. These were filled with mud, resembling thick paint of the finest qualitydiffering in color, from pure white to the various shades of yellow, pink, red, and violet. Some of these boiling pots were less than a foot in diameter. The mud in them would slowly rise and fall, as the bubbles of escaping steam, following one after the other, would burst upon the surface, During the afternoon they threw mud to the height of 15 feet for a few minutes and then settled back to their former quietude. As we were about departing on our homeward trip we ascended the summit of a neighboring hill and took a final look at Yellowstone Lake. Nestled among the forest-crowned hills which bounded our vision lay this inland sea, its crystal waves dancing and sparkling in the sunlight, as if laughing with joy for their wild freedom, it is a scene of transcendent beauty which has been viewed by but few white men; and we felt glad to have looked upon it before its primeval solitude should be broken by the crowds of pleasure seekers which at no distant day will throng its shores. September 29 we took up our march for home. Our plan was to cross the range in a northwesterly direction, find the Madison River, and follow it down to civilization. Twelve miles brought us to a small triangular-shaped lake about 8 miles long, deeply set among the hills. We kept on in a northwesterly direction as near as the rugged nature of the country would permit, and on the third day (October 1) came to a small, irregularly shaped valley, some 6 miles across in the widest place, from every part of which great clouds of steam arose. From descriptions which we had had of this valley from persons who had previously visited it we recognized it as the place known as "Burnt Hole" or "Death Valley." The Madison River flows through it, and from the general contour of the country we knew that it headed in the lake which we passed two days ago, only 12 miles from the Yellowstone. We descended into the valley and found that the springs had the same general characteristics as those I have already described, although some of them were much larger and discharged a vast amount of water. One of them, at a little distance, attracted our attention by the immense amount of steam it threw off; and upon approaching it we found it to be an intermittent geyser in active operation. The hole through which the water was discharged was 10 feet in diameter and was situated in the center of a large circular shallow basin into which the water fell. There was a stiff breeze blowing at the time, and by going to the windward side and carefully picking our way over convenient stones we were enabled to reach the edge of the hole. At that moment the escaping steam was causing the water to boil up in a fountain 5 or 6 feet high. It stopped in an instant and commenced settling down20, 30, 40 feetuntil we concluded that the bottom had fallen out, but the next instant, without any warning, it came rushing up and shot into the air at least 80 feet, causing us to stampede for higher ground. It continued to spout at intervals of a few minutes for some time, but finally subsided and was quiet during the remainder of the time we stayed in the vicinity. We followed up the Madison 5 miles and there found the most gigantic hot springs we had seen. They were situated along the river bank and discharged so much hot water that the river was blood-warm a quarter of a mile below. One of the springs was 250 feet in diameter and had every indication of spouting powerfully at times. The waters from the hot springs in this valley, if united, would form a large stream, and they increase the size of the river nearly one-half. Although we experienced no bad effects from passing through the "Valley of Death," yet we were not disposed to dispute the propriety of giving it that name, it seemed to be shunned by all animated nature. There were no fish in the river, no birds in the trees, no animalsnot even a trackanywhere to be seen; although in one spring we saw the entire skeleton of a buffalo that had probably fallen in accidentally and been boiled down to soup. Leaving this remarkable valley we followed the course of the Madisonsometimes through level valleys and sometimes through deep cuts in mountain rangesand on the 4th of October emerged from a canyon, 10 miles long and with high and precipitous mountain sides, to find the broad valley of the Lower Madison spread out before us. Here we could recognize familiar landmarks in some of the mountain peaks around Virginia City. From this point we completed our journey by easy stages and arrived at home on the evening of the 11th. We had been absent 36 daysa much longer time than our friends had anticipatedand we found that they were seriously contemplating organizing a party to go in search of us.(Western Monthly, Chicago, July, 1870,)
