d, filling up all the lower
space, was a sheet of green water, some twenty miles broad
(Pyramid Lake). It broke upon our eyes like the ocean. The
neighboring peaks rose high above us. One peak, on the eastern
side of the lake, rises nearly forty-four hundred feet above
the lake, and on the side (toward which Fremont was looking)
one peak rises 4925 feet above the lake; and we ascended one
of them to obtain a better view.

The waves were curling in the breeze, and their dark-green color
showed it to be a body of deep water. For a long time we sat
enjoying the view, for we had become fatigued with mountains,
and the free expanse of moving waves was very grateful. It was
set like a gem in the mountains, which, from our position,
seemed to inclose it almost entirely. At the western end it
communicated with the line of basins we had left a few days
since; and on the opposite side it swept a ridge of snowy
mountains, the foot of the great Sierra. 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. The next morning the snow
was rapidly melting under a warm sun. Part of the morning was
occupied in bringing up the gun; and, making only nine miles,
we en
