There are also many examples of pre-Hispanic Pueblo rock art (both petroglyphs and paintings) depicting fighting warriors, human-stick figures, a flute player, footprints, handprints, bird tracks, plants, and geometric motifs, including mainly spirals and concentric circles, and possibly also historic Navajo petroglyphs. Additionally, several of the sites had plastered walls with painted murals on them with geometric motifs, including dots, zigzags, triangles, and birds. On almost every rock art panel historic inscriptions, named and dates are also present. Our second research area is Sandstone Canyon located roughly 16 kilometres northwest from the Sand Canyon locality. There we started initially to document huge rock art panels and dated to different periods, from ca. 500 B.C. until the turn of the twentieth century A.D.; they were created by various Native American cultures and tribes, mainly pre-Hispanic Pueblo and possibly Fremont cultures and historic Utes. All these canyons are part of the Canyons of the Ancients National Monument, a legally protected area managed by the U.S. Bureau of Land Management, Department of the Interior.
