In the Maymeja portion of the Chivay source all surface archaeological materials diagnostic to time periods prior to pastoralism belonged to multicomponent sites with a substantial pastoralist component. This settlement pattern reflects the exposed, windy nature of the Chivay source: all sheltered areas that may have had overnight occupation were reused. No sites that could be termed "residential bases", using the same criteria as the other blocks of the Upper Colca project survey, were identified in this area.

Projectile points dating to the Archaic Foragers period were located in course of the survey of Block 1. Unsurprisingly, these points were virtually all obsidian, and most appeared to have been broken during manufacture with longitudinal breaks and incomplete scar coverage. In addition, it appears that broken non-obsidian bases were occasionally abandoned at the obsidian source, perhaps in the process of reusing the haft with newly fashioned obsidian points. For example, the base of a chert point with evidence of pressure flaking [A03-122] was recovered on the southern slopes of the Maymeja area during the survey work.
