Journal July 1 Palo Duro Tree, Left-6 Jun, Kern Not light until 6 am, a few mosquitoes during the night. Rat traps set by myself, Carol, and Roy. Drizzle overcast at 6:30 am. Trails were in stony and earthy desert with small sick columnar cactus (not planted) with lots of lichen on it. About 130 live traps baited with rolled oats. Caught four Phrylotus darwinii at the top of a hill above Carol's line--the vegetation got richer with sand, a mousecat, etc. At one place found some rat-sized droppings. This location is about 4 km ENE Pucsova, 15 am. Then drove about a km north to a patch of Tillandsia in earth + stone desert, including arranged stones of human origin. Saw large scorpion, no mouse tracks. A few of the Tillandsia are flowering. Then drove about 12 kms to a red area of Tillandsia along the highway. Saw a few mouse and bird tracks in the Tillandsia and lots of mouse tracks close to the highway, sometimes only a few feet from the parking. Further from the road we followed one mouse track 36 yds and another metered 80 yds--both ends not found. Lots of tracks & footprints seen in the three places mentioned so far. Then drove up the canyon east of Palo Duro Tree. Various branches of road going side canyon & we followed one to an area with large stony yellow
