Coming down from Douglas Pass on scenic 139 we drove through the Canyon Pintado (Spanish for painted canyon) Historical Conservation Area. This area was the home to Native Americans from 0 to 1300 AD. Several stops along the way provided access to various features. This one I wanted to hike in and see for it had pictographs (painted symbols) rather than petroglyphs (etched in the rock).
I don't get to see many pictographs.
I found it amazing how well the colors have held up for all this time.
It was situated under a ledge so I doubt rain ever gets it wet.
The key word here is "theorized". They don't know.
You already know what I think from previous postings of Native American doodling.
