now mostly eroded away. Much of the drive from Tintupsoon above 13,000 ft is thin country rich in yucca's - mile after mile of yucca yucca country. Despite much boweating by the surfer boys. They gather only dead heads. Some yucca then cross out as low as 13,000 ft a couple of good quercus stands between 13-14,000 ft. Tried to count rings but could not - very close + indistinct; an [illegible]-inched tree is probably 50-100 yrs. old. Many seedlings at one spot. Down a ravine as low as 11,200 ft, down to Tarata. Jan 22 The Phyllotox in my hair, 2 minutes 's. Drove to Taena. Found the desert + the marshlands rather [illegible] boring this time. The lower vegetation sparse, dried or drying. Camped outside Taena, 3200 ft; some mild pineapple, dried burles, one little legume in front. Spider holes. Jan 23 Drove to Tarata, then just beyond it above to camp. Stuffed for photo about every 1000 ft; for vegetation etc. see photo record. Road goes over a pass about 11,500 ft, still desert, then drops down into the Tarata Valley, which is extensively terred + irrigated to a lush green with alfalfa, potatoes, 3/4 grown, corn, quinoa, a little grain; The arequias and malls totally grown with bushes & cactus. The road winds up the hill then the terred fields beyond Tarata, where we camped about 5 p.m.. A most beautiful and idyllic location: scattered step canyon + mountain scenery, green terred fields, level flats, a medley of bird songs (thrushes, cross sparrow, humming),
