A substantial Archaic presence in Block 2 takes the form of diffused, low density scatters with associated diagnostic projectile points along the edge of the pampa and frequently close to water sources. These finds are very difficult to differentiate from the pastoralist site occupation pattern and therefore these features will be described as a group, followed by generalizations about the characteristics of the environmental and cultural features of sites of this type in Block 2.

While the Archaic Foragers use of space largely overlaps with pastoralist occupation areas in Block 2, the use of lithics appears to differentiate the two. As was discussed in Chapter 3 (Section 3.4.4), the use of obsidian for projectile points expands dramatically at the end of the Archaic Foragers period both near the Chivay source and in the consumption zone.
