On the road into the the Needles District of Canyonlands National Park there is an archaeological site with more than 650 petroglyphs known as Newspaper Rock. The information given at the site says:
"Newspaper Rock is a petroglyph panel etched in sandstone that records approximately 2,000 years of human activity in the area. Prehistoric peoples probably from the Fremont, Anasazi, Navajo and Anglo cultures etched on the rock from B.C. time to A.D. 1300. In historic times Ute and Navaho people, as well as European Americans made their contributions.
In interpreting the figures on the rock, scholars are undecided as to their meaning or have yet to decipher them. The Navajo term for the rock is 'Tse' Hone' (Rock that tells a Story). Unfortunately we do not know if the figures represent storytelling, doodling, hunting magic, clan symbols, ancient graffiti or something else. Without a true understanding of the petroglyphs, much is left for individual interpretation."
