R.E. Johnson 1967 Journal May 27 Squaw Valley, Placer Co., Calif. (cont). To Granite Chief Mtn (9006), an unnamed peak (8880 ft approx), and Needle Pk (8971 ft). From Emigrant Pk, these peaks look ideal for rosy finches (cliffs & snow) & they are higher than Emigrant (8774 ft.) & Squaw Peaks (8885 ft.), however as one approaches them it becomes clear that rosy finches are not as likely to occur there. The peaks are on an east- west ridge. The south slope receives more sun than major slopes of Squaw & Emigrant which lie on a North-south ridge, and it has little snow, no water, and is covered with low brush (1/2 to 1 ft.). The north slope is deep in snow, covering whatever extensive cliffs that may exist. The snow is as loaded with insects as the snow on Emigrant Pk, so food probably isn't limiting. However because of this arrangement of the mtns, there are no areas where snowmelt causes extensive, moist ground & snow margins-- these being favorite feeding places of the finches. The cliffs which are present have fewer fissures (nest sites) than the other peaks (however Needle Pk [illegible] is OK in this regard). The cliffs on the unnamed peak are directly under snow cornices which keep falling over the cliffs. These peaks are also a bit west of the main divide & may be a bit warmer on the
