A relatively large percentage of obsidian cores were observed at this site, particularly in the southern sector by the houses and chulpasshown on Figure 6-79. It is notable that one half of the fifteen Ob1 cores found in Block 3 were found here, and they are relatively large cores for Block 3.

It appears that obsidian cores were being transported here from the Maymeja area disproportionately to the rest of Block 3. The other site with a large number of Ob1 obsidian cores (n=6) is Taukamayo [A02-26] that was tested with the A02-26u1 unit and the u2 profile.
