The Crust field of the Gypsum section should be used to list stations where a crust of gypsum is observed.
A gypsum crust is a poorly adhered layer of gypsum usually over bedrock or breakdown. Often there will be noticeable space between the crust and the structure that it covers. It usually appears as a thick, white crystaline layer but may be discolored by dirt, dust or any number of other stains. Gypsum crusts are often very fragile, brittle and easily broken if touched and though they sometimes appear substantial, they are not. The primary distinction between a gypsum crust and a gypsum coating is that a crust is thicker and less firmly adhered to the substructure.
