Aspen Shelter on the Old Woman Plateau in central Utah was a hub of deer hunting activity from 4,000 years ago until the end of the Fremont era, about AD 1200. Thousands of deer bones discarded at the site are evidence of these early hunters' success. Projectile points and miscellaneous butchering tools are common, as are milling tools and plant macrophytes. The Aspen Shelter occupation complements Sudden Shelter, a few miles south, where use ceased by the Late Archaic.
