Bordered by steep cliffs cut by rugged ravines, this is
the largest volcanic mesa in the Mojave Desert. Sloping gradually from the north to the south, the
vegetation changes from a pinyon-juniper woodland (Pinus monophylla and
Juniperus osteosperma) in the higher northern elevations to a creosote bush
scrub in the lower south. There is
also some sagebrush scrub on the mesa. Noteworthy
species found here include Yucca baccata, Krameria erecta, Thamnosma
montana, Lycium spp., Eriogonum spp., and Opuntia spp.
Rare species include Agave utahensis var. nevadensis, which is nearing
the southern limits of its range here, and Tetradymia argyraea. There is a rich desert fauna including the desert
bighorn sheep, Ovis canadensis, and mountain lion, Felis concolor.
Porcupines, Erethizon dorsatum, have been sighted here. The basaltic mesa cap and other rock formations date
from the late Miocene. Opal and
petrified wood have been found here. Natural
tanques and intermittent streams occur in the area.
Traces of Indian cultures are common. Integrity: Though there has been some logging, the
inaccessibility of the area has prevented extensive grazing; consequently the
mesa vegetation is virtually undisturbed. Vandalism is occurring since the
opening of a campsite nearby. Use: Educational, research, observational. December 1975
