but center, so both down to a meadow at about -> 12,000 ft + just off of the Cajones-Torquay Road. Spent the day there, set traps among boulder talus below the road: bushes, trees, weeds, some grass but not bunchgrass (4048 m castola + richu). In spite of the abundance of defidophyllum + several bunches, the absence of bunchgrass and abundance of shrubs and other such little annuals makes this seem lower than altflora. The dominant animal is thousands of woolly caterpillars crawling everywhere. April 3 night cloudy + warmer; morning all cloudy. We had about 50 museum species and 24 small Sherman out and caught 3 Bolomys leiposthi, 1 Ph. magister, and 12 Ph. darwini. Most of the darwini had truncated tails. Everybody pregnant. Left down river and grand up the hill, following signs to things but horrible red soil no other care on it. Eventually get to Soap Rocks. = 13,360 ft altimeter check: at benchmark 4048 m altimeter said 12,800 ft a benchmark at Soap Rocks said 4451 mm, altimeter said 14,140. Here: altimeter's reading 550 ft too low. When we made camp altimeter read 13,380 = 13,930 came past our old two camps, then on a new road, hopefully toward Santa Rosa but queer soil, saw no troutweed, no meadows, no rhass. Camped along a stream and Boobasis, defidophyllum, Festuca, and ayarita & cloudy all day. April 4 morning mostly clear, afternoon all cloudy. Spent the day dissecting owl pellets and manufaturing
