Elevation is wrong,you will be claiming the hill,
At some point you will cross 8B trail which will take you some where else,stay on 8A it will face piestewa peak at the top of it ,
You can do a loop if you find the trail trough the parking at piestewa which should be at the hill facing piestewa peak,which should be harder to clim,then just an easy way down until you reach the trail you starter earlier,
Nice hiking all around about 1hr and 45 min to 2hr on a nice pace.
Note:
The picture of the trail posted is only half way of the loop,which mostly of the people do,you can go up to the top of the hill,it will be another 10 to 15 minutes,the mountain pictures were taken from up there
