A typical chaparral community is found on the moderately sloped sides of this long canyon, with chamise, Adenostoma fasciculatum, scrub oak, Quercus berberidifolia, and manzanitas, Arctostaphylos spp., prominent. Along the creek bed there is a riparian community. The area is inhabited by a wide variety of animals. Populations of three species of kangaroo rats are found here, Dipodomys agilis, Dipodomys merriami and Dipodomys stephensi, the latter being a rare species. Among the reptiles are the collared lizard, Crotaphytus collaris, leopard lizard, Crotaphytus wislizenii wislizenii, and the zebra-tailed lizard, Callisaurus draconoides. There is also a population of the Southwestern toad, Bufo microscaphus, which is uncommon and has a spotty distribution. A variety of rock formations is found in the canyon, ranging from pre-Cenozoic granitic and metamorphic rocks to the Pleistocene fluvial or lacustrine deposits of the Bautista formation, which contain numerous vertebrate fossils. Integrity: Relatively undisturbed, though there is an off-road vehicle trail along the creek bed. Use: Research, educational, observational, light recreation, public section; remainder, private.
