Mount Hayden is an 8,362-foot (2,549 m)-elevation summit located in the Grand Canyon, in Coconino County of Arizona, United States.

[3] The first ascent of the summit was made in May 1978 by Joe Sharber, George Bain, and Abra Watkins via the north side (class 5.9 A2).

[5] The summit spire of Mount Hayden is composed of cream-colored, cliff-forming, Permian Coconino Sandstone caprock.

[6] This sandstone, which is the third-youngest of the strata in the Grand Canyon, was deposited 265 million years ago as sand dunes.

Below this Coconino Sandstone is reddish, slope-forming, Permian Hermit Formation, which in turn overlays the Pennsylvanian-Permian Supai Group.
