A portion of this site is located under the modern town of Santa Rosa. The main architectural complex is a large platform, about 50 meters square, with terraces descending to the lacustrine plain below. The platform itself is adjacent to the Santa Rosa cemetery. The site lies on the boundary between the modern communities of San José and Santa Rosa. The platform lies in San José.
The entire site covers approximately 13.75 ha. The main occupations are from the Tiwanaku and Early Colonial Periods. However, the site's first occupation dates from the Middle Chiripa phase. The Middle Chiripa component, sector A, covers approximately 5.0 ha (population index value of 276), and therefore counts as the largest Middle Chiripa site encountered in the survey. This occupation is deeply buried by later deposits, however, and I am not entirely confident of its precise boundaries. This is a question to be resolved by subsurface testing. There can be no doubt, however, that this is a major Middle Chiripa site.
