There are a few low shrubs which appear to be deciduous.
The lower edge of the forest contains a few clumps of a species
of Ceanothus. Young pines are quite sparse, but there are
a few clumps of very young trees under the canopy of larger
ones. The same is true of the Bigcone Spruce. There are
very few if any outcroppings of rock on the summit area,
but the ground is covered by a coarse soil, apparently of
granitic origin.
The weather was clear and sunny but
cold and windy all day long. In shaded areas the frost
remained all day long. About noon the wind increased
in velocity and remained very strong all afternoon. It
was from the north and west. Birds were not in very
great evidence. Oregon Juncos were the most abundant
and were feeding in flocks throughout the area,
particularly in the open campground. Acorn Woodpeckers
were also much in evidence. Nearly all of the seed
pine trees contained very many of their storage holes,
many full of acorns. They were calling frequently in
the morning but less often in the afternoon (correlated
with the rising wind & falling temperature?). They were
quite shy and I failed to collect one although I
passed up chances during the morning. Pymy Nuttall's
were seen several times in both oaks and conifers, usually
in groups of about 6. I collected a solitary individual
from an oak. In the lower area I saw 2 White-breasted
Nuthatches in the oaks & Digger Pines and collected one.
Mountain Chickadees were common and were seen
