Hayden Butte (also called "A" Mountain) is the local "mountain" for Arizona State University and stands 1,495 feet tall. It gets its nickname "A" Mountain from the giant, painted "A" on the side of the hill. The name Hayden Butte is the official name of the summit. The trail can get pretty busy, but it's fun to run and power hike to the summit early in the morning before the crowds and heat get going.

Once you navigate this point, you'll be rewarded with a pleasant resting area to enjoy.
