Ollajaya Pata is a large Pacajes-Inka site located in the modern community of Ñacoca. The sherd scatter is quite dense and continuous, covering some 4.2 ha (population index: 228), and the soil is dark and stained with organic material. I would imagine that there are preserved subsurface features and deposits. The site is located in the gentle slope immediately above the lakeshore. The locality is used for agriculture at present, and the modern surface consists of plowed and fallow fields. A small group of springs is located nearly, in a quebrada to the west of the site itself.
This site would appear to be a small village, though large by post-Middle Horizon standards. A small Late Pacajes farmstead (sector B) is also present on the site, covering only 0.36 ha.
