Navajo Sandstone is a geologic formation and particularly prominent in southern Utah, where it forms the main attractions of a number of national parks and monuments including Zion National Park. These unique sandstone cliffs range in color from cream, to pink, to red. They could be described as sand castles crowning desert canyons.
The geology of the Zion canyons area includes nine known exposed formations. Together, these formations represent about 150 million years of mostly Mesozoic-aged sedimentation in that part of North America. At various periods in that time warm, shallow seas, streams, ponds and lakes, vast deserts, and dry near-shore environments covered the area.
