General Account
while the valley region is given
to sage bush, and and and
another unknown bush having a
compound flower. Along the
river there are a few yellow
pines, a few willow (and
a border of green grass.
The grass has been well grazed
down by the cattle. The river
is not large about 15-10 ft
wide and not over 2 ft. deep.
At present the water is
quite muddy due to a cloud
burst yesterday. The soil
here is a coarse orangish
tan gravel. It is of granite
origin which had a predominance
of feldspar.
Last evening I set 100 mouse
traps, 5 rat traps, 13 gopher
traps and 1 mink trap.
Aug. 11 My catch this morning
consisted of 7 Thomomys bottae,
1 Neotoma fuscipes, about 30 Peromyscus
maniculatus. This afternoon
I caught 3 more gophers. Three
more gophers this evening.
Aug 12 Catch - 6 Peromyscus
maniculatus, 2 Dipodomys,
2 Reithrodontomys, 6 Thomomys
