Long hike to get to this place but it was worth it! I think this is my favorite rock art.

This art was created by the Fremont culture sometime between 1100 and 1300 AD.

The white, shield-like drawings are typical of Fremont art, although there is no evidence that the Fremont people ever established permanent dwellings in this area.

Of even greater interest and historical value is the very faint collection of reddish-brown paintings beneath the Fremont's work. These pictures are thought to have been made by the Archaic People who lived here between 2,000 and 8,000 years ago.
