Geology

The summit spire of Brady Peak is composed of cream-colored Permian Coconino Sandstone.[4] 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. Precipitation runoff from this feature drains east into the Colorado River via Nankoweap Creek.
