About three miles from the divide the road strikes the valley of Trail Creek, a small-sized trout-stream of great clearness and purity, flowing southeastward to the Yellowstone, between high hills wooded at the summits. Approaching the river, the country becomes more and more volcanic in appearance, masses of basaltic lava cropping out from the high ridges on the right and left. Many of these masses show a perpendicular front of several hundred feet, with projections resembling towers, castles and the like. Several miles away on the right, is Pyramid Mountain, a snow-capped peak. Farther to the south is a long range of mountains, also covered with snow, even in midsummer. On the left of the valley the foot hills bear abundant verdure, the highest summits being covered with a vigorous growth of pines. Trail Creek enters the Yellowstone about thirty miles from Fort Ellis. Ten miles further up the Yellowstone is Bottlers' Ranch, the last abode of civilized man in this direction. The Bottler brothers, who have established themselves here, belong to that numerous class of pioneers who are satisfied only when their field of operation is a little in advance of civilization, exposed to privation and danger, yet possessing advantages for hunting, trapping and fishing not enjoyed by men content to dwell in safety. These, however are not their only occupations. They have under cultivation large fields of wheat, potatoes and other crops, possess extensive herds of cattle, and make large quantities of butter, for which they find a ready market in the mining camps of Emigrant Gulch across the river, which at this point is a very rapid stream, about three hundred feet wide and four feet deep on the riffles at low water.
