According to the Köppen climate classification system, Masonic Temple is located in a cold semi-arid climate zone, with precipitation runoff draining south to the Colorado River via Hakatai Canyon from the west aspect, Burro Canyon from the south aspect, and Muav Canyon from the east aspect. This butte is an erosional remnant composed of strata of the Pennsylvanian-Permian Supai Group overlaying the conspicuous cliffs of Mississippian Redwall Limestone, in turn overlaying the Cambrian Tonto Group.Ralph Lee Hopkins, Hiking the Southwest's Geology: Four Corners Region, 2002, The Mountaineers Books, , page 91.
Etymology Masonic Temple was named by George Wharton James as a tribute to the Order of Freemasons, an organization to which he belonged.Gregory McNamee, Grand Canyon Place Names, 1997, Mountaineers Publisher, , page 80. To James, the immense angular walls below Dutton Point seemed to form a square, and the freemasonry expression "on the square" suggested to him the name.George Wharton James, In and Around the Grand Canyon, 1900, Little, Brown, and Company, page 98. This feature's name was officially adopted in 1908 by the U.S. Board on Geographic Names.
