Rimrock Draw Rockshelter

            In the summer of 2016, the BLM Burns District continued its partnership with the University of Oregon Museum of Natural and Cultural History and the Oregon Archaeological Society and conducted archaeological excavations at the Rimrock Draw Rockshelter site in southeastern Oregon.

The site, discovered in 2009 by BLM Archaeologist Scott Thomas, has hosted archaeology field schools since 2011. In 2015, it became internationally known after archaeologists found a small stone tool under a layer of volcanic ash from a volcanic eruption about 15,800 years ago.

This tool suggests one of the oldest known human occupations in the western United States.

The 2016 excavations encountered significant rock and boulder debris, resulting from at least two occasions of portions of the rock wall calving or breaking off – probably around 8,000 and 10,000 years ago. These rocks limited access to the ground beneath them, and many were removed only after drilling and splitting reduced them to removeable sizes.

In coordination with the BLM’s Scott Thomas, Dr. Patrick O’Grady with the University of Oregon Museum of Natural and Cultural History directed excavations for the fifth year in 2016, and Jordan Pratt, graduate student at Texas A&M University, served as the excavation’s site supervisor. Volunteers from the Oregon Archaeological Society, students from the University of Oregon, and archaeologists from the BLM conducted the excavations.
