R.E. Johnson 1967 Journal 14 May 29 Castle Peak area, Nevada Co., California (cont.) rodent, ex. marmot?). These were surrounded by orange lichen. The remainder or the rock was covered by black lichen & occasional patches of green lichen. The orange lichen only occurs around the white deposits. A pika was heard calling in the rocks between the upper & lower set of cliffs_ on the south slope of Castle Peak at 3:50 pm. In summary of the rosy Finch situation, Very few were seen (5 sightings) on the two peaks The only cliffs that appear occupied or occupiable are those on the N face of Castle Peak. No rosy finches were seen among the lower south facing cliffs. Neither peak, nor the ridge between them, provided any sizeable areas of moist ground with small brooks of melt water and tender fresh sprouts of vegetation (locations of this type are common on Emigrant Peak & rosy finches commonly feed at these sites). [Insects were abundant in the snow however.] & west South slopes at high elevations are snow free & dry. North & east slopes are solid snow. Ridge tops receive little or no melt water, thus no moist ground, etc. This may be the factor most restricting the rosy Finch on these peaks.
