Just southwest of the area of the obsidian workshop, on the south perimeter of Maymeja, an extensive construction area (1 Ha) was encountered on the rocky slope along the edge of the bofedal that was generally terraced although heavily eroded. This area is shown in more detail on the map in Figure 6-54.

The construction along the margins of the bofedal was curiously devoid of ceramics, as were the other terraces immediately adjacent to the A03-126 Maymeja workshop. A light scatter of obsidian flakes is found throughout the terraced area, however, and obsidian flakes are concentrated along the base of the slope although these concentrations probably reflect downslope movement of artifacts. In this sector, on the south-west edge of the bofedal, several Late Horizon "Collagua-Inka" plates were encountered, and it is possible that this entire sector was constructed at a later time. The corner of a structure with a possible niche that appears to be built using the Inka-influenced cut-stone masonry technique was found 70m southwest of the obsidian workshop [A03-126] inside the larger terraced site area [A03-275]. Unfortunately, the remaining sides of this structure are too eroded to permit an estimate of the structure size, or to discern if it was a residential or mortuary construction. A pattern discussed by Wernke (2003) in the Colca valley was for circular residential structures to be dominant among pastoral settlements above 3900m. Given this architectural pattern, the structure at A03-339 is perhaps a square chulparather than a residential structure.

The presence of diagnostic Late Horizon materials in the obsidian source area was somewhat unexpected because during the Late Horizon the regional distribution of Chivay obsidian was relatively restricted in comparison with any time period since the Terminal Archaic. It is possible that the Late Horizon occupation in this area, particularly the painted plates, result from ritual functions associated with the abundant spring that irrigates the bofedal in the southern of Maymeja area, and that spring emerges very close to this location. However, if the structure [A03-339] is a looted Late Horizon chulpa, then the plate could have been one of the grave goods.

A03-240 "Molinos 1"

The only local Middle Horizon evidence from Block 1 close to the Chivay source comes from a pastoral area part of the way up the Quebrada de los Molinos climbing up from Chivay, 350 vertical meters above the town. This site is found adjacent to several large breccia boulders near a bofedal where the trail climbing from Chivay levels out after a steep pitch. A partially eroded rim sherd [A03-242.1] was found here that is diagnostic to the local Middle Horizon style. The sherd is made of burnished brown paste and with traces of paint on the rim, but the rim was too small to take a measure of the vessel diameter.
