Sacramento Mountains Most of this range of mountains is sparsely covered by
creosote bush scrub on a rocky substrate; however, in portions (see Bigelow Cholla Natural Area)
there are excellent stands of bigelow cholla, Opuntia bigelovii.
This cactus, which is more typical of the Sonoran Desert though it is not
uncommon in the southern Mojave, is found here in association with other more
typical Sonoran forms. Animal life is typical of the drier and lower desert
ranges. Geologically, the range is complex, with Pre-Cambrian
granitics, gneisses, and igneous rocks forming the main body.
There are some Tertiary intrusives and volcanics as well as some probable
mid-Miocene sedimentaries. These
latter are rich in fossils. Integrity: The
area is virtually undisturbed. Use; Research,
educational, observational. Some
private. December 1976
