ASU’s Deer Valley Petroglyph Preserve is home to an archaeology museum, the largest collection of Native American rock art in the Phoenix area and 47 acres of Sonoran Desert preserve. A ¼-mile trail takes visitors into the desert to view the petroglyphs carved into the basalt boulders of the Hedgpeth Hills, as well as native plants and wildlife. The preserve is part of the Center for Archaeology and Society in the School of Human Evolution and Social Change.
