Morales [25, p. 117] estimates that if the residential areas are included, Pacopampa would cover an area 400 meters wide and 1000 meters long. Located ARCHAEOLOGICAL SITES TESTED roughly equidistant from the Pacific shores of northern Peru and the heavily forested tropical banks of the Marañon Pacopampa River, Pacopampa had strong exchange ties with coastal and eastern lowland peoples as well as the highland peoples Pacopampa is a large public center established during further to the south, and these links have been confirmed by the late Initial Period and occupied continuously through the archaeological research [13, 31]. Unlike the formative center at Chavin de Huantar, which is located at the bottom of a deep valley at 3150masl, Pacopampa is placed on the crest of a hill in the jalca zone (2000–2900masl), about 1000 meters above the deeply entrenched Chotano River. As a consequence, most of the agricultural land within Pacopampa’s catchment area is in the surrounding quechua zone or the lower yunga-like temple zone (1200–2000masl). These lands are suitable for FIGURE 14-1 Map showing archaeological sites in Peru with stable FIGURE 14-2 Panorama of the Pacopampa platforms and surrounding isotope analyses. environment. Photo: R.
