Dr. Patrick O’Grady of the University of Oregon will lecture on April 1 at Oregon Museum of Science and Industry on artifacts discovered at Rimrock Draw Rockshelter in southeastern Oregon. The artifacts, discovered during the past three years, date back to 4,000 to 12,000 years ago.

O’Grady’s lecture begins at 7:45 p.m., following a 7 p.m. general business meeting; both are open to the public.

He will cover the past three years of excavations in Rimrock Draw, where he runs a field investigation workshop for students during the summer. Topics will include stone tool assembly, stratigraphic layering and dating volcanic ash layers. His main areas of research include human settlement and mobility patterns, hunter-gatherer subsistence practices, zoo-archaeology and Holocene trends in North America.

Rimrock Draw Rockshelter has prime archaeological conditions such as sedimentary depth, stratigraphic integrity and intermittent volcanic ash lenses that facilitate preservation.
