Humphrey's Peak is the tallest in Arizona. When driving up Phoenix, it has quite the intimidating look to anyone who has never seen this mountain range. However, when going north from Phoenix, the mountain you are actually looking at is Agassiz Peak, not Humphrey's. It was windy at the summit. Some rangers even gave Keegan and me stickers for summiting in the conditions. I would almost take the wind, though, for zero bugs. Bugs are a big problem at the summit here.
