Cedar Mesa Sandstone is the remains of coastal sand dunes deposited about 245–286 million years ago, during the early Permian period.[3] Coloration varies, but the rock often displays a red and white banded appearance as a result of periodic floods which carried iron-rich sediments down from the Uncompahgre Mountains during its formation.[3][4]

Named after topographic Cedar Mesa near the San Juan River in Utah,[2] exposures of Cedar Mesa Sandstone form the spires and canyons found in the Needles and Maze districts of Canyonlands National Park,[3] the inner gorge of White Canyon,[5] and the three natural bridges of Natural Bridges National Monument.[6]
