The Kayenta Formation frequently appears as a thinner dark broken layer below Navajo Sandstone and above Wingate Sandstone (all three formations are in the same group). Together, these three formations can result in immense vertical cliffs of 600 metres (2,000 ft) or more. Kayenta layers are typically red to brown in color, forming broken ledges.
The Kayenta Formation pinches out and disappears to the north, in the Uintah Basin, and the Wingate Sandstone and Navajo Sandstone become indistinguishable. These remaining eolian beds have sometimes been mapped as simply Glen Canyon Formation, but they correlate with the Nugget Sandstone further north, and it has been recommended that they be ...

Fossilized footprints of dinosaurs and the crocodile-like tritylodonts can be found in this 350 foot (107 m) thick ledgy-slope forming formation, called the Kayenta. [7] The Kayenta weathers into three units; a lower ledge and middle cliff that are dominated by cross-bedded sandstone and an upper slope that has relatively more siltstone.
Kayentasuchus (meaning "Kayenta Formation crocodile") is a genus of sphenosuchian, a type of basal crocodylomorph, the clade that comprises the crocodilians and their closest kin. It is known from a single skeleton found in rocks of the Sinemurian-Pliensbachian-age Lower Jurassic Kayenta Formation, northeastern Arizona.
The next member in the Moenave Formation is the thin-bedded Whitmore Point, which is made of mudstone and shale. [11] The lower red cliffs visible from the Zion Human History Museum (until 2000 the Zion Canyon Visitor Center) are accessible examples of this formation. [3] Kayenta Formation
Dilophosaurus is known from the Kayenta Formation, which dates to the Sinemurian-Toarcian stages of the Early Jurassic, approximately 196–186 million years ago (187–190 mya has also been suggested, and the age of the Kayenta is considered complex).
Parting lineation, from lower right to upper left; Kayenta Formation, Canyonlands National Park. The Glen Canyon Group of formations includes (from oldest - lowest - to youngest) the Wingate Sandstone, Kayenta Formation, and the; Navajo Sandstone; These formations are most prominently exposed in the western and northern sections of the park.
