Relatives of the general population who manufactured the Inca trail, Peruvian developers know their stuff. Yet, it's the tracery, the oversaw stream of force, that has our regard. The street rises old seabeds, slopes secured with bone, cracked dry edges with cornices etched via avalanches. Late morning, we wind up on a high pampas possessed by a large number of vicuña and alpaca. Out there, our first sight of snowcapped pinnacles. There are stone corrals on adjacent slants, one-room cottages. Amidst this goliath no place, a solitary shepherd strolling in favor of the slope.
