First time on this one, was hoping for cloud cover to help with the heat. Well, it started out that way but the clouds disappeared and it got hot! My guess is about 90 degrees (hot for a Flagstaffian). Went to the cabin, and on up the next 3/4 mile to the other side of the mountain. This is a very up and down trail--starts high, down to a saddle, up Secret Mountain, down to the cabin, up to the lookout, across the mountain, up some more, then you are at the rim. I'm guessing at the AEG. Very buggy, too. Needed a couple applications of spray.
