Block 2 survey area represents a transition from the rugged lava flow topography on the west side of the block to the open pampa on the east side of the block. In addition, residents in the Block 2 area are able to exploit the higher density off resources in the puna while maintaining access and, perhaps, social relationships with residents in the adjacent lower altitude portions of the Colca valley.

A number of obsidian projectile points in this area were produced in the same general forms as chert points and, particularly, as fine-grained volcanic points. These forms are most akin to those documented at Sumbay, 30 km to the south. Given the greater local variability in point forms during the Late Archaic (Klink and Aldenderfer 2005: 53), the data from the Block 2 area provides an opportunity to study the local projectile point styles, best known from the Sumbay style points, in conjunction with the regional interaction documented through obsidian distribution data.
