Hot is right! There were some people that had no business at all down there. I am not one to question a person’s sense of adventure but when you are way overweight and barley make it by some miracle down there, you are going to be in trouble. Rescue is $4,000 if you can't get out on your own. It is not a recomended time to be hiking it but on top of the canyon (the rim) it was nice and clear with a gentle breeze.
