R.J.Raitt 1956 Journal Jan.29 3 mi. NW Rabbit Peak area, Riverside Co. Calif. first two canyons entering the main Martinez canyon from the south upstream from us. We Got an early start leaving camp at 6:40 AM and headed for the northeast (downstream) corner of the elevated erosional surface (which has been cut into by pres- ent canyons to a depth of over 100'). We were agreeably surprised to find a trail ascending to the surface and then heading for a ridge which appeared to be a good one to ascend to reach the higher levels. When we reached this ridge about an hour out of camp the trail headed down into the canyon to the northwest so we left it and ascended the first peak on the ridge. When we got to the top of this peak we found that we had to go down on the other side to a low saddle in the ridge. As we got to the low point we again encountered the trail coming back from our right. From then on we followed this trail clear into the east-west canyon which we had descended two days ago and in which I had shot both a junco and a Titmouse. After we had climbed to the top of a high ridge and were more or less descending into this canyon of our destination we heard a Thrasher calling down a short distance in a small gully. We chased down after it and Dr. Miller shot it. Some distance farther on
