Navajo Sandstone is a type of sedimentary rock primarily composed of quartz grains. It is known for its striking red and orange colors, which result from iron oxide in the rock. Formed during the late Jurassic period, this sandstone was created from ancient sand dunes that were deposited in a desert environment. This rock formation is most famously found in the Zion National Park and Grand Canyon areas of the southwestern United States. Its unique layering and texture make it a popular subject for geological studies and photography, showcasing the natural beauty of the region.
