Tower of Set is a 6,012-foot-elevation (1,832-meter) summit located in the Grand Canyon, in Coconino County of Arizona, US.

Tower of Set was originally named Temple of Sett in 1879 by Thomas Moran, for the Egyptian deity of war, Set, because a niche worn into its wall evoked temples in the valley of the Nile.

[2] In 1919, Harriet Williams Russell Strong proposed connecting Hopi Point and Tower of Set across the river via an aerial tramway, an idea that never came to fruition.

[6] The top of Tower of Set is composed of the reddish Pennsylvanian-Permian Supai Group.

[7] Further down are strata of Mississippian Redwall Limestone, the Cambrian Tonto Group, and finally granite of the Paleoproterozoic Vishnu Basement Rocks at river level.
