• coordinate based on unpublished field data

Collection methods: Brian Anderson and Roger Wagerle, students at the University of California at Riverside, discovered the site in 1992 while conducting a geological study of the Book Cliffs area. Together with their advisor Mary Droser, and another graduate student, Reese Barrick from the University of Southern California, they pursued an excavation permit. William Stokes at the Utah BLM Office suggested they use BYU as a designated repository with Ken Stadtman’s collection expertise
