Here is the "keyhole" trail of Longs Peak, the tallest mountain in Rocky Mountain Natl Park, at 14,259feet, one of the tallest mountains in CO. Its dangerous, but if you're prepared, it is an extraordinary climbing experience, according to National Geographic, and I agree. The "bullseye" red & yellow dots in the photo's bottom middle, were painted on the rock by rangers to mark the steep, snowy trail for climbers (wearing red.) At the top, chained to a rock is a pvc tube with climber registry
