Mile 72.5 - Unkar Delta and Rapid

Under the direction of archaeologist Douglas Schwartz, sites along the delta overlooking the rapid were excavated as well as dated showing settlement at two different times in 200 years from 950 to 1150 AD. At the height of occupation, the delta was home to several families who lived a seasonal and diverse lifestyle; gathering wild plants, practicing agriculture, and hunting wild game. The subterranean structures with their wall and room remnants, agricultural terraces, and pot sherd and lithic scatters; compose the largest archaeological site in close proximity to the river in the entire canyon.
