Guided by the on-the-ground efforts of Dave Page (Desert Research Institute) and Daron Duke (Far Western Anthropological Research Group), FGV source studies in Utah have been largely tied in with archaeological projects carried out in Tooele County at the Utah Test and Training Range (UTTR). In addition to artifacts from the project area sites, the Utah FGV sources identified during these investigations have also been found at Danger Cave (42-TO-13) and Bonneville Estates Rockshelter.
