Black and Opal Mountain This large area supports a sparse creosote bush scrub
community which includes Larrea tridentata, Ephedra sp., Atriplex sp.,
Bebbia juncea, and Ambrosia dumosa. There
is a small amount of Joshua tree woodland. The
relatively restricted Psorothamnus arborescens occurs in the area. Animals are comparatively abundant, particularly birds.
A number of raptors nest in the area, including the red-tailed hawk,
Buteo jamaicensis, and the uncommon prairie falcon, Falco mexicanus. Reptiles
are found in fair abundance here. Geologically, the area includes some Mesozoic granitics
but much of the region is of Miocene or Pleistocene volcanics in origin.
There are nonmarine Miocene sediments bearing the fossil Barstovian
fauna. A variety of minerals is also
present. Numerous sites of archaeological interest are found
here. Integrity: There
are several roads in the area and some off-road vehicle damage has occurred.
Some of the archaeological materials have been defaced or removed. Use: Research,
educational, observational. Some
private holdings. A sizeable portion
of the area has been tentatively designated an Outstanding Natural Area. December 1976
