Interesting Description of What Is Known as Yellowstone National Park: 16th () -Mr. Bridger came up with the remainder of the party. 18th-The whole camp moved down the east shore of the lake through thick pines and fallen timber about eighteen miles and encamped in a small prairie. 19th-continued down the shore to the outlet about twenty miles, and encamped in a beautiful plain which extended along the northern extremity of the lake. This valley was interspersed with scattering groves of tall pines, forming
shady retreats for the numerous elk and deer during the heat of the day. The lake is about 100 miles in circumference, bordered on the east by high ranges of mountains whose spurs terminate at the shore and on the west by a low bed of piney mountains. Its greatest width is about fifteen miles, lying in an oblong form south to north, or rather in the shape of a crescent. Near where we encamped were several hot springs which boiled perpetually. Near these was an opening in the ground about eight inches in diameter from which hot steam issued continually with a noise similar to that made by the steam issuing from the safety valve of an engine, and could be heard five or six miles distant.
