| Title | Gypsum in salt wash on U.S. 163, near Mexican Hat, Utah |
|---|---|
| Description | The white material in this photo is gypsum (hydrated calcium sulfate) that has precipitated as water in the salt wash evaporated. Gypsum is highly soluble and is a commonly precipitated salt. Most of the rocks exposed nearby are members of the Permian Cutler Group. Cutler Group rocks contain gypsum and generally have a red color, thus explaining why waters in this area are saturated with gypsum, and also the overall red color of the sandy sediments in this wash. |
