Pearson 1971 Aug 27 Frost on ground atd ice in coffee pot outdo, temp at 6:30 am was 0° C. Took pictures of Carabos then off to Cruzos about 3 p.m. more of same kind of country. Cruzo different, probably because a center because of the proximity of large areas of level land low enough for cultivation. Aug. 28 off for machu picchu by train at 7 a.m. around 11 a.m. and reconsters for trafficking possibilities and for solanaceae. Everything rather dry, in fact the only water was in the four brooklets up in the larger trce, and because of the extreme steepness of the slopes we were only able to reach one good brooklet and - a couple of small or half dried ones. The good one contained water, debris, assorted spiders, [illegible] damsel, etc., plus one big dark indescrict earthworm. just before dark set 46 small folding thermans baited with crumbled sugar. Most sets were on the bouldered brushy slope along the ruins (south). Vegetation was bamboo, orchids, bracken ferns, assorted shrubs waist to shoulder high, dry scattered cobwebs along a boulders, a little grass. Pretty dry, woody-green trees well. Aug 29 picked up traps at 6:30 am, not one tawled. Trace of dew, but temperatures mild, even at night. Looked at Inca ruins and climbed to top of Humay Picchu, flipping rocks looking for solanaceae. Only zoogeol find was vampire bat dropping in a dark cave-like room under the tower in the ruins. Left for Cruzo 3:15 and 6:30. Gezards outof Humay Picchu,
