On the right side of the picture you'll see a line that runs along the top of the plateu. This was a trail I took into the canyon. The pt. that the trail leads to is an overlook above the Colorado River. It was 7.3 miles from the brim to this overlook. Keep in mind, it is all down hill in and all up hill on the way out. Very backwards from most hikes people do where it's just the opposite. There is a lot of search and rescue in the park because of this. People underestimate their phyical condition and then add 90*+ heat to that and no shade. Dehydration is the biggest issue the rescuers have to deal with.
