The site of Pausa 1 was initially visited in 2002 following consultation with Dr. José Antonio Chávez (2001, Pers. Comm.) who explained that this entire area had been visited, and partially collected, by his student groups in the 1980s. Despite the earlier collection programs by Arequipa students, the 2003 survey team was able to locate large quantities of projectile points and some ceramics of both local and non-local stylistic groups. As described above, the raised corral structures are found along the edge of a large pampa paralleling the base of a lava flow from Huarancante. The broadest of these corral structures, and the group with the most interesting wall-base constructions, were the oval structures of Pausa. With a permit from the INC to place up to four 1x1m test units in this site the 2003 field team spent a number of weeks testing this site as reported in [Section 7.5] These test units revealed an occupation spanning the Late Formative Period, but ceramics and mortuary structures from later periods were also encountered here.

The structures at the Early Agropastoralist base of Pausa include two large, raised corral areas that are most evident because large rocks form a circle that appear to be wall bases from old corral walls. The largest of these rings is oval [A03-559] and it contains a smaller, circular structure [A03-558]. The larger rocks that encircle these features and form the wall bases are between 50cm and 100cm across, and the rocks are partially buried. Interestingly, the ovals all have approximately the same number of these large rocks (between 26 and 28), such that encircling the larger ovals the spacing between the rocks is larger than it is around the smaller ovals. As is evident in Figure 6-58, the rock spacing around A03-559 is approximately 5-7m, the spacing in A03-558 is highly irregular, and the spacing between rocks in the A03-557 oval is approximately 2-3m between rocks. The rocks could have represented the foundation rocks for corrals, but these would have been very substantial corrals and far larger than any contemporary corrals that were encountered in the region.
