Mount Hayden is an 8,362-foot summit on the North Rim of the Grand Canyon near Point Imperial, rising prominently above Nankoweap Canyon with about 5,000 feet of relief. Also called Hayden Peak, it is named for Arizona pioneer Charles T. Hayden, a leading figure in the territory’s development, founder of Tempe, builder of Arizona State University, and father of U.S. Senator Carl Hayden; the name was officially adopted in 1932. Its layered profile reflects Coconino Sandstone over the Hermit Formation and Supai Group. Drainage flows east toward the Colorado River, and the peak later became known for technical climbing routes first ascended in 1978.
