July 6, 1863: Tuolumne Meadows
[Today] Hoffmann and I visited a peak about four miles north of camp, to complete our bearing for this region. It is a naked granite ridge, about 10,500 feet high, and like all the rest commands a sublime view. We found mosquitoes on the very summit, and on a table-land at about nine thousand feet, in an open forest, they swarmed in myriads. On this table we found a pretty lake, of very clear water, about a mile long—a most picturesque sheet of water. These little lakes abound here in the higher Sierra.Specimens collected: Viola pinetorum subsp. pinetorum; Microseris nutans; Juncus chlorocephalus; Hemizonia minima; Cassiope mertensiana subsp. californica; Luzula divaricata; Oxyria digyna; Raillardella scaposa; Monardella odoratissima subsp. glauca; Lonicera conjugialis; Carex raynoldsii; Saxifraga californica; Saxifraga bryophora.
