The break between the two, a topographic unconformity,may be distinctly traced. Combined with these topographic features are certain climaticfeatures of equal precision. Between 7,000 and 13,000 feet is azone of clouds oftentimes marked out as distinctly as the belt offog on the Peruvian coast.^ Earely does it extend across the val-ley. Generally it hangs as a white belt on the opposite the up-valley winds of day begin to blow it drifts up-valley,oftentimes to be dissolved as it strikes the warmer slopes of theupper valley, just as its settling under surface is constantly beingdissolved in the warm dry air of the valley floor. Where the pre-cipitation is heaviest there is a belt of woodland—dark, twistedtrees, moss-draped, wet—a Druid forest. Below and above thewoodland are grassy slopes. At Incahuasi a spur runs out anddown until at last it terminates between two deep canyons. Noordinary wells could be successful.
