The Kayenta Formation
The Kayenta formation was formed during the late Triassic period stretching to the early Jurassic period. During a time of receding waters, a great erg was formed, a massive sand sea stretched over much of what is now western America. These sands eventually compressed into the cross-beds of red sandstone and silt-stone that make up the Kayenta formation today. The Kayenta is a bench former. Somewhat more resistant to erosion than wingate & Navajo It is above the Wingate and below the Navajo formations. The rocks are a pink salmon color and thicken westward. It spans all the way from the South West Arizona into South West Colorado, and stretches through Zions National Park.
