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
