Cushenb Cushenbury Canyon cuts the northern scarp of the San
Bernardino Mountains, opening onto Lucerne Valley. Vegetation in much of the
canyon is primarily an open pinyon, Pinus monophylla, woodland with scattered
Joshua trees, Yucca brevifolia, scrub oak, Quercus turbinella, Western juniper,
Juniperus occidentalis, and Great Basin sagebrush, Artemisia tridentata.
At the lower end of the canyon there is a creosote bush scrub; in the
higher elevations the pinyon grades into a Jeffrey pine, Pinus jeffreyi, forest. Several rare or uncommon plants occur in the area,
Arenaria ursina, Calochortus striatus, Cordylanthus
and Erigeron parishii. Animal life ranges from typical desert to montane
species. In the mid-elevations the canyon cuts through the
Carboniferous Furnace limestone. The
upper reaches are Mesozoic granitics, the lower, Quaternary alluvium.
There are several springs in the canyon and an intermittent stream. Integrity: State
Highway 18 runs near the canyon floor and there are several buildings.
Near the mouth there is a cement plant.
The vegetation is virtually undisturbed save for several areas by the
creek and in the vicinity of the cement plant. Use: Research,
educational, observational, present. Some private. January 1981
