Navajo Sandstone is a geologic formation in the Glen Canyon Group that is spread across Arizona, northwest Colorado, and Utah. Navajo Sandstone frequently occurs above the Kayenta Formation and Wingate Sandstone, the other formations of the Glen Canyon Group. Together, these three formations can result in immense vertical cliffs of up to 2,200 feet (670 m). Atop the cliffs, Navajo Sandstone often appears as massive rounded domes and bluffs that are generally white in color. It can be distinguished from adjacent Jurassic sandstones by its white to light pink color, meter-scale cross-bedding, and distinctive rounded weathering
