PEARSON 1955 a fox or dog dropping containing mouse jaw, well up on hill. Went polelighting among Tillandsia at 8:30 but saw nothing except one Pearsonwill. aug.23 Still no fog in a.m. although whole valley is misty clammy. Fog banks crawl down the valley. Trap line of almost 2 bags of carefully placed traps produced only one mouse, a young [illegible] P-thrills. No birds seen while running traps at 7 a.m., no mice also. There are widely scattered fragments of human? bone and pottery on the slope, and a few obviously separated graves. One east-facing slope beside Tillandsia had lots of small tufts of branched stelaion lichen. This locality to be 2 mi. E Chocan, 2000 ft., Chillon Valley, Dept. of Lira. For future reference there is good Tillandsia flora at km 32 on Santa Road. Right by road, off-the-road climbing place, 3 or 4 species of Tillandsia, many small shells, but saw no mouse droppings. After passing through Lira drove up to 1 mi. W Suero, 6000 ft. (Dodge billboard) and set traps in a slide of huge granite chunks plastered out of the railroad above. Vegetation includes the valley tree, Centium plant, fuzzy stick cactus, a small yucca, weeds, and the red-flowered leafless "fig". Then drove down to 1 mi. E. San Bartolome, 5200 ft., and set traps on the steep cliff above the place where found the phyllosteg and young DOR. It is a few hundred yards east of the Zubirga rat trap line in the weeds. It is also about 1 mi. W of the famous Puente Carim.
