Photograph by O.F.Cook TERRACED VALLEY BOTTOM AT OLLANTAYTAMBO All the open fields are broad, artificial terraces. A large aqueduct or causeway, about a mile long,carried onwalls 15to30feet high, seen in the middle of the picture, crosses the valley in a nearly straight line. A part of the town is seen in this view from thenorthern bank ofelevated terraces or hanging gardens. In the lower right-hand corner is the end of the projecting ridge thatcarries thehanging gardens. The town is surrounded on three sides by large agricultural terraces (see pages 438 and 440). The valley at thispoint isabout amile broad and overhung by steep mountains about a mile high. Several banks of terraces, their true size dwarfed by the mountain above, can bemade outalong thebase of the rocky slope. This view is from the slope above the hanging gardens.
