Mayhew 1958 Aug. 5 Journal 94. Colorado Desert, Calif. tigris were already active when we arrived. We drove into the area about as far as the car would go, then walked into the mouth of Deep Canyon for about ¼ mile. By this time (0800) only Uta were seen moving, and not many of them. One Uta moavensi was seen about 20 feet above the canyon floor just inside the mouth of the canyon. The remains of an adult Sauromalus obesus we found at the same place in a crevice about 10 feet above the floor. Water had come down the canyon from last week's rains, so there were still damp spots in depressions near boulders in the stream bed. Fresh mountain sheep tracks were seen in nearly every one of these damp depressions, but we saw no sheep. Ocotillo are again in leaf in this area, and Belleperone is in bloom. Some new leaves were also seen on the palo verde. Nearly all of the perennials are quite green. We then proceeded down highway 99 past the Salton Sea to highway 78. San Felipe Creek had water flowing under 99, but not under 78. However, one could see where it had been flowing quite recently there.
