The rocks that make up this landscape formed in environments that are very similar to ones we can observe on the earth's surface today as well as ones that occur beneath the surface where tectonic plates collide to form mountain ranges.
The Kayenta Formation is a sandstone that is more resistant to erosion than many of the other sedimentary rocks in the park. The Kayenta Formation was deposited by a high-energy braided river system similar to the Rio Grande River in New Mexico.
The Wingate Formation is a tan sandstone whose sweeping tilted layers tell us that this rock was deposited in a desert environment where wind-swept sands accumulated and were buried. An environment like this can be found in the modern Sahara Desert of North Africa.
The Chinle Formation is primarily a reddish-brown mudstone that likely was deposited in densely-vegetated floodplains or mudflats with small ponds and streams. This environment is similar to the coastal environments in South America and Africa.
