Jacha Winto is a substantial, dense sherd scatter, located on the slopes of a large quebrada in the modern community of Huacullani. The scatter covers 3.23 ha, with a population index value of 170. Near the center of the site is a substantial terrace (50x50 m) which may represent some for of corporate construction.
Like Titicachi (T-415), Jacha Winto is unusual in being a single component Tiwanaku site. It is further distinguished by being only Tiwanaku Period village located more than 2 kilometers from the modern lakeshore. In fact, it lies almost 5 km from the lakeshore, more than twice as far as the next most distant Tiwanaku village in the survey area (Pichuria K'ucha, T-160). The quebrada in which the site is located is unusual in that it is the only place between Taraco and Tambillo (a > 40 km stretch of the Taraco hills) that is a major thoroughfare between the lakeshore and the Tiwanaku Valley. The modern road passes through the community of Rosa Pata and connects Huacullani with the Tiwanaku Valley town of Pillapi, and is passable by motor vehicles year-round. This was almost certainly an important road in prehistory as well.
Jacha Winto has a third distinction: it is the only Tiwanaku site in the Taraco Peninsula survey area on which I found non-local Middle Horizon ceramics. One fragment of a ring-footed vessel of the Mojocoya Tricolor style - possibly from the Cochabamba region - was recovered from the surface. This specimen, not illustrated here, is almost identical to one published by Janusek in his dissertation ([Janusek 1994]:Figure 10.26).
