(April 2 cont.) Perognathus penicillatus - 3 P. spinatus -1 (only animal caught in rocks) Perognathus sp. - 2 Utah Shot a Socalophorus around camp while shining & also an interesting slender lizard (#1778) which was on the shaggy back of the mesquite tree in our camp & matched it perfectly. It even "froze" with its head arched upward which made it look just like a strip of bark. We broke camp about 1530 & returned to San Felipe where we purchased some pan & then headed N after attempt to find the dirt road which goes W from San Felipe to Valle de San Felipe & Valle de la Trinidad, 7.6 mi. N San Felipe (by rd) we saw a Swainson's Hawk (observed perched as well as flying). We turned W. on the dirt road to El Valle de la Trinidad & went down this road 1.6 miles & made camp at sunset (31 mi. N, 7 mi. W San Felipe). I set 46 traps & NIL set 25. There was quite a bit of old deserti - sign, but nothing fresh. There was some fresh warren sign. The soil here was still very sandy but not as dry. Beaver came to look for water. The vegetation was sparser with fewer mesquite & palo verde & slightly more cactus the last camp. The day had been very hot (well over 100° F.). The night was also warm, mostly clear, with almost no moonlight.
