Rock layers of the Moenkopi Formation in Zion National Park
The Moenkopi Formation is a geological formation that is spread across the U.S. states of New Mexico, northern Arizona, Nevada, southeastern California, eastern Utah and western Colorado. This unit is considered to be a group in Arizona. Part of the Colorado Plateau and Basin and Range, this red sandstone was laid down in the Lower Triassic[1] and possibly part of the Middle Triassic, around 240 million years ago.[2]
