Nature
O'Neill Butte is a prominent summit on the South Rim of the Grand Canyon near Grand Canyon Village, Mather Point, and Yaki Point, with the South Kaibab Trail passing its east slope. Its importance comes less from absolute height than from its dramatic rise above the Colorado River and inner gorge. The butte also reveals a compressed cross section of the canyon’s geology, from Permian Esplanade Sandstone and the Supai Group down through Redwall Limestone, the Tonto Group, and the ancient Vishnu Basement Rocks at river level. It was named for William Owen “Buckey” O’Neill, whose Grand Canyon work and later fame linked his name to the canyon.
