Workings of moles were found on the Pacific slope of the mountains from
1600 feet at Claremont up to 7500 feet on Blue Ridge, and on the Pacific
slope beneath basin sagebrush in Cajon Canyon one mile from desert slope
Joshua-tree flats, but not on the desert slope, although moles probably
occur on that slope in some of the places where there is suitable
habitat.
Near Camp Baldy in the sandy soil beneath groves of alders moles seemed
to be especially abundant. Although common on the coastal face of the
range, moles shunned compact, dry, or rocky soils. In the greasewood
chaparral one-half mile west of the mouth of Palmer Canyon, where the
soil was hard and rocky, mole tunnels were in soft soil that had
accumulated at the edge of a fire road beneath a steep road cut. The
assumption is that this accumulation contained insects attractive, as
food, to the moles.
