ELevat. 700*. Biatom ridge at mouth of side canyon extend-
ing s.e. from Panoche Canyon l/2 m. from its mouth (at
point where Hiway 180 swings out around a knob extending
from s. wall). Biatomaceous earth (thick vertical strata)
being mined from snout of ridge on e. side - considerable
disturbance up to couple months ago. Only woody plant is
Atriplex polycarpa in crk. bottom. This Amsinckia seems to 1
be an introduction - only on disturbed portions and where
tractors have packed soil. Another species (see 924a and
924b) seems native and grows in masses. This species ia
.plentiful but not massed. Much Matricaria suaveolens alsn.
