|---|---|
| Stratigraphic range: Early and early Late Mississippian[1][2] | |
 Redwall Limestone cliff, and upper platform of cliff extension (resting on very short Muav Limestone cliff), from Tower of Set, central Grand Canyon, adjacent Granite Gorge. The bottom of Redwall cliffs typically rest on sections of Temple Butte Formation-(locally), or attached sections of Muav Limestone cliffs (regionally exposed in Grand Canyon, elsewhere in Arizona, not always with surface exposure). | |
| Type | Geological formation |
| Underlies | Supai Group and locally Surprise Canyon Formation. The Surprise Canyon Formation fills local paleovalleys, caves, and collapse structures cut into the underlying Redwall Limestone. |
| Overlies | Muav Limestone and Temple Butte Formation |
| Thickness | 244 m (801 ft), at maximum |

The Redwall Limestone is an erosion-resistant, Mississippian age, cliff-forming geological formation that forms prominent, red-stained cliffs in the Grand Canyon. these cliffs range in height from 150 m (490 ft) to 244 m (801 ft). It is one of the most fossiliferous formations exposed in the Grand Canyon region.[1][2]
