This formation spreads across the Colorado Plateau province of the United States, including northern Arizona, northwest Colorado, Nevada, and Utah. Vertebrate tracks known as Chelichnus gigas from the Coconino Sandstone in Grand Canyon.
The Middle Permian Toroweap Formation is a thin, darker geologic unit, between the brighter colored units of the Kaibab Limestone above, and Coconino Sandstone below. It is a prominent unit in Grand Canyon, Arizona, Southwestern United States, found through sections of the South Rim, Grand Canyon, and the North Rim, of the Kaibab Plateau; also the Kaibab's southeast extension to Cape Royal ...
Coconino Sandstone, (prominence, Permian unit) Hermit Shale, Permian; Supai Group, (4 units, Pennsylvanian-Permian) 4 – Esplanade Sandstone, (Permian) (Typically forms a resistant (& thick) cliff, thickening in Western Grand Canyon) 3 – Wescogame Formation
As defined by Darton, the Supai formation included all Pennsylvanian-Permian strata, mostly red beds, lying between the Redwall Limestone and the Coconino Sandstone in the Grand Canyon region. In 1923, Noble [2] recognized and separated the strata now comprising the Hermit Shale from the top of Darton's Supai.
sandstone, unit-1, labeled in Tonto Group. The summit spire of Zoroaster Temple is composed of cream-colored, cliff-forming, Permian Coconino Sandstone with a small, remnant Kaibab Limestone and Toroweap Formation caprock. [9] The sandstone, which is the third-youngest of the strata in the Grand Canyon, was deposited 265 million years ago as ...
The summit dome is composed of cream-colored Permian Coconino Sandstone. [6] This sandstone, which is the third-youngest stratum in the Grand Canyon, was deposited 265 million years ago as sand dunes. Below the Coconino Sandstone is reddish, slope-forming, Permian Hermit Formation, which in turn overlays the Pennsylvanian-Permian Supai Group.
The summit of Manu Temple is composed of cream-colored, cliff-forming, Permian Coconino Sandstone, which is the third-youngest of the strata in the Grand Canyon, and deposited 265 million years ago as sand dunes. [7] Below the Coconino Sandstone is slope-forming, Permian Hermit Formation, which in turn overlays the Pennsylvanian-Permian Supai ...
The top of Chuar Butte is composed of Permian Kaibab Limestone, which overlays cream-colored, cliff-forming, Permian Coconino Sandstone. [7] The sandstone, which is the third-youngest of the strata in the Grand Canyon, was deposited 265 million years ago as sand dunes.
