R. MOON 1987 Journal 48 3 May Bull Canyon, Granite Mountains (near Kelso), San Bernardino co., CA. I led a hike with UCSC's mammology class, into Bull Canyon from Cottonwood Canyon and the old road up to Silver Peak. We were supposed to open two sites of pitfall traps at two springs in the canyon. On the old dirt road to Silver Peak, in cottonwood Canyon, we saw several Desert Marigolds growing singly and in clusters in the soily and rocky areas on the way up to the base of the steep hills. We also saw a Desert Spring Lizard where the trail to the saddle on the ridge begins. Up on the ridge we saw a Panamint Chipmunk on a piñon pine among the granite boulder peaks. We all trail blazed down into the canyon and made our way to a spring in the upper canyon that we call Columbine spring (since there are columbine plants there). I opened 14 traps at the spring while everyone else ate lunch in the shade of the pines. By the time we finished there it was getting near the time we said we'd be cont'd.
