The Redmond Canyon quadrangle is in the transition zone between the Colorado Plateau and the Basin and Range physiographic provinces, and includes parts of the Valley Mountains and the adjacent Sevier Valley. Small knolls, known locally as the Redmond Hills occur along the eastern border of the quadrangle. Consolidated strata exposed in the Valley Mountains are over 4,000 feet thick, and include the North Horn Formation, which may be Paleocene or Eocene in age; the Flagstaff, Colton, Green River, and Crazy Hollow Formations, which are probably Eocene in age; and the Sevier River Formation of Miocene to Pliocene age. Small outcrops of Jurassic Arapien Shale and Miocene Osiris Tuff, and larger exposures of bentonitic clay and travertine of probable Oligocene age crop out in the Redmond Hills.
