Steamboat Mountain is a 7,410-foot summit on the Grand Canyon’s North Rim at the north end of Powell Plateau in northern Arizona. Nearly encircled by Galloway and Saddle Canyons, it stands out for its dramatic relief, rising more than 5,400 feet above the Colorado River in just three miles. Its runoff drains west to the river through Tapeats and Stone Creeks. The mountain’s name recalls Lieutenant Joseph Ives’s 1858 Colorado River expedition by the steamboat Explorer and was officially adopted in 1932. It also displays a clear sequence of canyon rock layers, from Kaibab Limestone and Coconino Sandstone down to Vishnu Basement Rocks at river level.
