Abstract: Rimrock Draw Rockshelter in Harney County, Oregon, has produced numerous artifacts, botanical remains, and sedimentary deposits indicative of both a nearby marsh and substantial stream. Crescentic stone tools are frequently associated with shallow desert lakes and plants like wapato, bulrush, and wada, are also found in similar settings. Massive rounded boulders in the channel adjacent to the rockshelter attest to long term and high energy stream flow. This presentation will focus on how the archaeology and sedimentology at the rockshelter guided us to search for and discover the ancient hydrologic system that made the site attractive between ca. 18,000 to 7,000 years ago.
