We now pass through a section noted for its wild and picturesque scenery and considered the pleasantest on the trip. In leaving the Upper Basin we follow along Firehole River to the mouth of Spring Creek, then along this creek to the Continental Divide. From there, travelling a few miles along the Pacific slope, we cross the Divide and descend the mountains into the valley of the Yellowstone. Near the central part of the park, encircled by a forest and elevated nearly eight thousand feet above the sea-level, lies a remarkable body of water supplied by ice-cold streams formed by the melting snow on the surrounding mountains. This body of water, of which the Yellowstone River is the outlet, is the famous Yellowstone Lake, thirty miles long and twenty miles wide; it is filled with trout. Here the fisherman can catch hundreds of trout in a short time, but unfortunately most of them are afflicted with a parasitic disease, rendering them unfit for food. Researches have been made seeking the cause of the disease in order, if possible, to apply a remedy, but so far to no purpose. It is conjectured that the superabundance of fish together with a dearth of suitable food lowers their vitality, thus rendering them liable to disease. Yellowstone stands next to Lake Titicaca as the highest large body of water in the world. The sunrise and sunset effects on the lake are most beautiful. A steamer plies on the lake carrying mail and passengers. The bird life on this body of water and its shores is represented by swans, geese, ducks, cranes, pelicans, curlews, herons, plovers, and snipe. For beauty and grandeur the lower falls and canyon of the Yellowstone River are unsurpassed. A body of water seventy feet wide rushes forward with impetuous speed and joyously takes a leap of more than three hundred feet to the rocks below, where, breaking into millions of particles, it forms a great cloud of spray. The water then dashes on with renewed vitality between the walls of a canyon fourteen hundred feet deep, and most gorgeously painted by nature in such a variety and lavishness of tints that they defy the most skilful artist to reproduce them. As one gazes from the edge of the chasm into and along the depths below, he attempts in vain to measure the fulness and beauty of this handiwork of nature. He is too amazed for utterance and remains spellbound, communing only with himself and nature regarding the unfathomable significance of such marvels. When the famous painter, Thomas Moran, desired to reproduce in colors on canvas this masterpiece of nature, he gathered his inspiration from Artist Point, and after he had finished the celebrated painting which now adorns the Capitol at Washington, he acknowledged that the beautiful tints of the canyon were beyond the reach of human art.
