Here is a collection of photos taken in various locations, showing historic and prehistorical marks of humans upon the land.
This amazing petroglyph panel spans 2000 years in its creation. Location: near Canyonlands NP, southeastern Utah.
Found on the wall of a protected alcove formed from sandstone, this was the most elaborate of the designs. Location: Canyonlands NP.
Likely built by the Fremont in the 8th or 9th century, I believe, these small mud-and-stone structures were designed to store and protect grain and corn from damage from pests and weather, as the nomadic people traveled from season to season.
Historical hunt(?) scene
A herd of bighorn sheep are shown surrounded by riders on horseback, dating these petroglyphs to at least the mid to late 16th century. They are skillfully executed.
Location: along trail to Delicate Arch, Arches NP.
What is that figure on the lower right side supposed to be? This panel predates Picasso, suggesting that Cubism was perhaps invented by the Navajo living or passing through Chaco Canyon, NM ;). It is believed to post-date the Anasazi who lived in the area in the 9th through 12th century, however.
Birds and animal quadrupeds are seen, along with a few sun spirals. These panels are unreachable except with a ladder, suggesting that the lower rock the artist(s) used has fallen away.
