BOTTLERS' RANCH TO GARDINER'S RIVER.

At Bottlers' Ranch the wagon road terminates. For the first ten miles beyond, the trail runs along the west bank of the river through the wildest imaginable scenery of rock, river and mountain. The path is narrow, rocky and uneven, frequently leading over steep hills of considerable height. From the top of one of these, a bold mountain spur coming down to the water's edge, the view up the valley is very fine, embracing the river fringed with cottonwoods, the foot hills covered with luxuriant, many-tinted herbage, and over all the snow-crowned summits of the distant mountains. Above this point the valley opens out to a "bottom" of large extent and great beauty. Across the river the steep lava mountains come close to the stream, their lofty fronts covered with stunted timber. A large portion of the bottom land is subject to overflow by the numerous mountain streams that come in from the right, and bears an abundance of grass, in many places waist high. The river is skirted with shrubbery and cedars, the latter having thick trunks, too short for ordinary lumber, yet of beautiful grain for small cabinet work, and susceptible of exquisite finish.

At the head of this valley is the second caÑon of the Yellowstone, granite walls rising on either side to the height of a thousand feet or more, and the river dashing through the narrow gorge with great velocity. Seen from the lofty mountain spur over which the trail is forced to pass, the bright green color of the water, and the numerous ripples, capped with white foam, as the roaring torrent rushes around and over the multitude of rocks that have fallen from above into the channel, present a most picturesque appearance. Above the caÑon, which is about a mile in length, the valley widens slightly, then narrows so as to compel the traveller to cross a ridge, on whose summit lies a beautiful lake. Descending to the valley again the road traverses a tract of level bottom land, a mile or two wide, covered with a heavy growth of sage-brush. Throughout all this portion of its course, the Yellowstone is abundantly stocked with trout of the largest variety known this side the Rocky Mountains.

Some ten miles above the second caÑon on the edge of the river valley is Cinnabar Mountain, whose weather-beaten side presents one of the most singular freaks of nature in the world. Two parallel vertical walls of rock, fifty feet wide, traverse the mountain from base to summit, and project to the height of three hundred feet for a distance of fifteen hundred feet. The sides are as even as if wrought by line and plumb. The rock between the walls and on either side has been completely worn away. Speaking of this curious formation, Mr. Langford says:

"We had seen many of the capricious works wrought by erosion upon the friable rocks of Montana, but never before upon so majestic a scale. Here an entire mountain-side, by wind and water, had been removed, leaving as the evidences of their protracted toil these vertical projections, which, but for their immensity, might as readily be mistaken for works of art as of nature. Their smooth sides, uniform width and height, and great length, considered in connection with the causes which had wrought their insulation, excited our wonder and admiration. They were all the more curious because of their dissimilarity to any other striking objects in natural scenery that we had ever seen or heard of. In future years, when the wonders of the Yellowstone are incorporated into the family of fashionable resorts, there will be few of its attractions surpassing in interest this marvellous freak of the elements."

According to the observations of Dr. Hayden, the mountain is formed of alternate beds of sandstone, limestone, and quartzites, elevated to a nearly vertical position by those internal forces which acted in ages past to lift the mountain ranges to their present heights. Standing at the base and looking up the sides of the mountain, the geologist could not but be filled with wonder at the convulsions which threw such immense masses of rocks into their present position. Ridge after ridge extends down the steep sides of the mountain like lofty walls, the intervening softer portions having been washed away, leaving the harder layers projecting far above. In one place the rocks incline in every possible direction, and are crushed together in the utmost confusion. Between the walls at one point is a band of bright brick-red clay, which has been mistaken for cinnabar, and hence the name Cinnabar Mountain. The most conspicuous ridge is composed of basalt, which must have been poured out on the surface when all the rocks were in a horizontal position. For reasons best known to himself, one of the first explorers of this region gave these parallel ridges the title of "Devil's Slide."

"The suggestion was unfortunate," writes the historian of the Expedition, "as, with more reason perhaps, but with no better taste, we frequently had occasion to appropriate other portions of the person of his Satanic Majesty, or of his dominion, in signification of the varied marvels we met with. Some little excuse may be found for this in the fact that the old mountaineers and trappers who preceded us had been peculiarly lavish in the use of the infernal vocabulary. Every river and glen and mountain had suggested to their imaginations some fancied resemblance to portions of a region which their pious grandmothers had warned them to avoid. It is common for them, when speaking of this region, to designate portions of its physical features, as "Firehole Prairie,"—the "Devil's Den,"—"Hell Roaring River," etc.—and these names, from a remarkable fitness of things, are not likely to be speedily superseded by others less impressive."

These "impressive" titles stand in curious contrast with the fanciful names bestowed in this region by Capts. Lewis and Clarke,—Wisdom River, Philosophy River, Philanthropy Creek, and the like.

From the Devil's Slide to the mouth of Gardiner's River, twelve miles, the ground rises rapidly, passing from a dead level alkali plain, to a succession of plateaus covered slightly with a sterile soil. Evidences of volcanic action begin to be frequent: old craters converted into small lakes appear here and there, prettily fringed with vegetation, and covered with waterfowl. Scattered over the hills and through the valleys are numerous beautiful specimens of chalcedony and chips of obsidian. Many of the chalcedonies are geodes, in which are crystals of quartz; others contain opal in the centre and agate on the exterior; and still others have on the outside attached crystals of calcite.
