Isis Temple is a prominence in the Grand Canyon, Arizona, Southwestern United States. It is located below the North Rim and adjacent to the Granite Gorge along the Colorado River. The Trinity Creek and canyon flow due south at its west border; its north, and northeast border/flank is formed by Phantom Creek (Phantom Ranch, about ) and canyon, a west tributary of Bright Angel Creek; the creeks intersect about southeast, and north of Granite Gorge. The Isis Temple prominence (a short remainder caprock of bright-white Coconino Sandstone, on an erosion slope of brownish Hermit Formation), is only about lower than Grand Canyon Village, the main public center on Grand Canyon’s South Rim. Isis Temple is about directly north of Grand Canyon Village on the South Rim, Grand Canyon; the Village is the west terminus of Arizona Route 64 (East Rim Drive), and north terminus of U.S. 180, from Valle, Arizona, and Williams (about south). Isis Temple is part of an uplifted, and sub-faulted block (about long and wide), with a sub-peak landform, Cheops Pyramid , about lower in elevation, and southeast of the Isis Temple prominence. The Isis prominence is composed of erosion resistant cliff-forming Coconino Sandstone. Trails The North Kaibab Trail accesses the Bright Angel Canyon route. Views of Isis Temple, or routes to the region are from the middle, or lower Bright Angel Canyon-Phantom Creek region, the flatlands around Isis, Cheops and the block southeast, called Utah Flats; one of the trails leads to the viewpoint at the Isis-Cheops Saddle. From the North Rim, the Tiyo Point Trail has views of Isis Temple from the north. Geology The prominence of Isis Temple is composed of the Coconino Sandstone, at , (a similar elevation to the North Rim, Grand Canyon, Kaibab Plateau, and the Coconino is geologic member no. 2 of the 4 units of Permian age; unit 4, Kaibab Limestone makes up the Kaibab Plateau). Below the cliff-former Coconino Sandstone is eroded, slope-forming Hermit Shale, upon the uppermost Supai Group 'redbeds' member the cliff-forming, Esplanade Sandstone-(see Tuckup Trail). After the thick sequence of 'redbeds', the cliff-forming Redwall Limestone sits above highly eroded slopes of Muav Limestone and Bright Angel Shale. These slopes are deposited upon the cliff-forming unit of Shinumo Quartzite. The Shinumo Quartzite forms the cliff-base of Isis Temple, with highly erodable units forming the slopes below, the colorful, yellows, reds, and purplish colors from the Hakatai
