Depending on the degree of re-occupancy in prehistory, the principal pastoral base sites with their associated corrals that were recorded are larger than one would expect given modern pastoralist behavior in the area. The herd sizes that noted in the Block 2 area during fieldwork between August and December 2003 were not carefully studied, but the herds seemed sufficiently large to use a corral 50m long corral as was noted at Pausa. However, herds would not require many corrals like Pausa in one area unless the herd sizes were significantly larger, perhaps growing and shrinking with the seasons. There are corrals of comparable size in the region, but the uncertainty lies in judging how many of these corrals were in use simultaneously.

It is possible that these corrals were used by passing caravans. As a perimeter settlement represented largely by groups linked to Colca Valley communities (as indicated by ceramics styles), it is possible that these larger facilities were designed to host passing caravans.
