Its position at first inclined us to believe it Mary's Lake, but the rugged mountains were so entirely discordant with descriptions of its low rushy shores and open country, that we concluded it some unknown body of water, which it afterwards proved to be.
On January 13th we followed again a broad Indian trail along the shore of the lake to the southward.

For a short space we had room enough in the bottom; but, after traveling a short distance, the water swept the foot of the precipitous mountains, the peaks of which are about 3000 feet above the lake.

The trail wound around the base of these precipices, against which the water dashed below, by a way nearly impracticable for the howitzer.

During a greater part of the morning the lake was nearly hid by a snowstorm, and the waves broke on the narrow beach in a long line of foaming surf, five or six feet high.

The day was unpleasantly cold, the wind driving the snow sharp against our faces; and, having advanced only about twelve miles, we encamped in a bottom formed by a ravine, covered with good grass, which was fresh and green.
We did not get the howitzer into camp, but were obliged to leave it on the rocks until morning.
