Massive, sandstone formations, hundreds of meters high, tower over Sedona, Arizona, USA. The red color found in many sandstone formations is caused by iron oxide found in various amounts throughout the rock and is due to the same chemical reaction that causes rust. Sandstone originates from the breakdown of older rocks through various processes of erosion. | |
