June 25, 1863: Tenaya Lake
Camp 116 [Today] we came on to Lake Tenaya, a most picturesque alpine lake, about a mile long and half a mile wide, of clear, cold, ice water, lying 8,250 feet above the sea. Its clear waters are very blue and very deep, no fish live in it, it is too high for the water to have air enough in it to support them. Scattered pines are around the lake, or grow in the crevices of the granite. Above rise domes of granite, many of them naked, while patches of snow lie around on every side. Of course it freezes every night.
