Yanapata is another major Formative Period site that lies on the boundary between the modern communities of Nachoca and Ñacoca. The bulk of the site lies in Nachoca. It is located at the base of the Taraco hills, approximately 200 meters to the south of the modern road. The site covers 8.0 ha, and is visible from the road as an area of dark soil.
The site has a large terrace, 50 by 40 meters, similar to that described for Chiaramaya, above. This terrace was apparently once faced with stone on its downslope side. One large limestone pillar remains in place in approximately the center of the terrace wall. I was informed by the landowner that a great deal of worked stone was pulled from this area and taken by truck to Taraco to be used in repairs to the church there. Apart from stone-robbing, modern disturbance of the site in minimal, and is limited to a single house immediately to the east of the main terrace.
Sector A covers a single hectare located south and west of the main terrace. With a population index of 43, this is one of the smaller Early Chiripa sites.
