P. PEARSON 1952 Then left for Mazorung, Santa Rosa. About an hour to camp up Mazorung - a process involving makeshift cans, rubber hoses, cardboard funnels, short measure etc... as in other parts of Peru. Put 7 "latas" in my 30-gallon tank. Then to just behind Santa Rosa for night. Road alarmingly no signs of tracks of Rio's a Tutupaca truck. April 16 Drove to the river Colan-Sojo, lunch and stopped there for lunch, bainent, wash, etc., in preparation for dry camp at Tutupaca. Just leaving when Steinways drove up behind me in their Jeep pickup on way to Condorane. Dropped off, then to our two camp at Tutupaca where I put out trees (rafts) at 5 p.m. about 12 fresh digging's on the cerano area.

Probably because of the volcanic nature of the soil (ash, gravel, etc.) the vegetation does not mount very high. No streams from melting snow, no green stuff. Lost trees at 15,800 ft. Lizards here too. Some up to a way quite bare at 15,900 ft., first snow about 16,000 ft. The miner's shocks (camphirents)
