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.
The fossilized plants and animals in the Moenkopi are evidence of a climate shift to a warm tropical setting that may have experienced monsoonal, wet-dry conditions. [8] The Red Canyon Conglomerate, the basal member of the Moenkopi, fills broad east-flowing paleochannels carved into the Kaibab Limestone. [9]

Moody Canyon is informally sub-divided into two units: [10] a lower slope-forming 200 to 300 foot (60 to 90 m) thick unit of reddish-brown siltstone and; an upper cliff-forming 120 to 130 foot (37 to 40 m) thick unit of reddish-orange siltstone.
