Pichuria K'ucha is a large sherd scatter located in the modern community of Nachoca. The scatter is continuous and very dense, covering 4.25 ha. The site appears to be deeply stratified. At the time of my visit, a large portion of the site had only recently been plowed with a tractor for the first time. Large sherds and whole vessels had been exposed, together with many features such as hearths and burials. The site clearly represents a medium-sized Tiwanaku village, with a population index of 231 (Sector B). With the exception of the tractor-plowing the site seems to be reasonably intact. Only one modern house (of two stories) is located on the site itself.
The site is very unusual in one respect at least. It is located on a low terrace at the confluence of two perennial watercourses, at the bottom of a quebrada and at a considerable distance (> 2 km) from the lakeshore. It is one of only two sizable Tiwanaku sites on the Taraco Peninsula (the other being T-365, below) which is not located on the lake-facing slopes of the hills, and within 1 km of the lakeshore. The significance of this topographical distinction is uncertain, but probably indicates agricultural intensification in less-desirable locales.
There seems to have been a very ephemeral LF2 occupation on the site, as well (Sector A). This was a small farmstead, with a population index of only 6.
