A03-1074 "Pokallacta"

This is a small, sheltered site that has evidence of occupations in both the Archaic Foragers period and subsequent times. The site is immediately to the west of a steep tuff outcrop approximately 100m high. The site is in the shadow much of the day, but it is a sheltered location that is protected and yet offers large views of the river valley.

The rock shelters are fronted by a flat area that today is a corral. This flat activity area is mapped as two Structure Loci though they are essentially one terrace. The two loci delimit the artifact spill zone for each respective rock shelter and each structure locus was assigned the same ArchID number as the rock shelter above it.

The bifacially flaked items are largely obsidian but notably the bulk of the grab sample of unmodified flakes was of chert and chalcedony. This reflects the location of the site on the north side of the Río Llapa, and is consistent with a raw material use pattern observed elsewhere on the survey.

This rock shelter has a very thick dung cap and it is difficult to see the ground. The slanting roof and open west side provides a large but only partly sheltered area. It appears that a protective wall was constructed on the west side in the past.

A03-1076

This rock shelter is the more protective residential shelter of the two, offering a view of the river valley and the surrounding terraces.
