The Glen Canyon Group is a geologic group of formations that is spread across the U.S. states of Nevada, Utah, northern Arizona, north west New Mexico and western Colorado. It is called the Glen Canyon Sandstone in the Green River Basin of Colorado and Utah. [1] There are four formations within the group.
The "Kayenta Fish Fauna" is the last one recovered from the Glen Canyon Group sequence and it is delimited mostly to the silty facies of the Lower-Middle Part of the formation. [8] This Fauna is rather scarce and delimited to several concrete locations with proper lacustrine or fluvial deposition, and are also scarce due to preservation bias. [8]

The Moenave Formation is a Mesozoic geologic formation, in the Glen Canyon Group. It is found in Utah and Arizona. The Moenave was deposited on an erosion surface on the Chinle Formation following an early Jurassic uplift and unconformity that represents about ten million years of missing sedimentation. [1]

Wingate Sandstone frequently appears just below the Kayenta Formation and Navajo Sandstone, two other formations of the Glen Canyon group. Together, these three formations can result in immense vertical cliffs of 2,000 feet (610 meters) or more.
Mud flats developed on top of the eroded surface of the Glen Canyon Group, forming the Carmel Formation. The massive cliff-forming Entrada Sandstone in turn was created on top of the Carmel. A long period of erosion stripped away most of the San Rafael Group in the area along with any formations that may have been laid down in the Cretaceous ...
Glen Canyon Group in southeast Utah. At top are massive beds of Navajo Sandstone separated by thinner beds of the Kayenta Formation from massive beds at bottom of the Wingate Sandstone. In geology, a group is a lithostratigraphic unit consisting of a series of related formations that have been classified together to form a group. Formations are ...
