Red Mtn, 5300 ft. 14 mi. S Hayford Trinity Co. Calif
Sep.8
Soon after dark I heard a screech owl in
camp & about 9:45-10 p.m. I spotted owls (see
species accounts). The evening was clear and
windless with a bright moon. Also saw 1
flying squirrel run into a hole, in a dead snag,
heard it come out again - got the flashlight on it
in time to glimpse it as it scurried up the
trunk. A moment later I heard the typical
"plop" of its landing on another tree, followed
by more rustling of its nails on the bark.
Sep.9
About 8:30 a.m. I started Southward along
the ridge toward Red Mtn itself, which is
2 1/2 mi. from our camp. The ridge trends ESE for
about half that distance. The vegetation along
the ridge is similar to that near our camp -
since I have not covered this in detail I will
list the associations recognized here & their
major component species:
1. Open pine forest - on most slopes, thinning
out toward the ridges or on serpentine ex-
posures. Dominants: Pinus ponderosa,
Pinus jeffreyi, and hybrids of same (abundant);
Larocedrus decurrens, Pines lambertiana (few).
Interstitial - understory: Quercus garryana
(more over 20 ft. high), Ceanothus cordulatus,
Arctostaphylos patulae, Ceanothus prostratus,
amelanchier alnifolia, Prunus emarginata,
Symlocarpous sp.
