Tributary to Trabuco Canyon, this canyon
has an almost perennial stream that begins near the summit of Santiago Peak . Three plant communities are present in the canyon. The
dominant is chaparral. Along the
stream bed there is an excellent riparian community, with white alder, Alnus
rhombifolia, the most prominent element. Near the head of the canyon there is a
coniferous forest with big-cone Douglas fir, Pseudotsuga macrocarpa, and
madrone, Arbutus menziesii. This
canyon is one of the very few places in the County that the madrone occurs. Geologically, the lower portion of the canyon is
underlain by the upper Jurassic Bedford Canyon formation which includes
argillite, slate, quartzite and graywacke. In
the upper section the Jurassic Santiago Peak volcanics are well exposed. Integrity: Near
the mouth of the canyon there are some cabins and a dirt road, and there is a
well-used trail in the area. Most of
the vegetation is relatively undisturbed. Use: Research,
educational, observational, light recreation. March 1977
