Doug Nering is getting to be a Grand Canyon expert! From a report sent by Deborah:
We found numerous petroglyphs (paintings on rock) and pictographs (pictures carved into a rock face), especially in Flip-Off Canyon. Doug also located a spring nearby, as well as an old “cowboy camp.” The last night we camped near an Anasazi (around 1200 AD) site. Our camp was underneath an overhanging Supai sandstone ledge which kept us totally dry during the rain throughout the night.
