Map Satellite 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
