My son, Curtis, waits for me to catch up during the descent from Green Mountain at Black Canyon of the Gunnision National Park, CO. I was stopping here and there to take a few pictures. Curtis is perched atop Painted Wall. That's more than a 2,000' drop to the canyon bottom, making it the highest cliff in the state. Some of the rock coloration that gives Painted Wall its name is visible on Exclamation Point at the top, left of the image. Taken in August 2006.
