Anotations

Scope note:

A fine grained ferruginous sandstone quarried in Arizona that can be buff, brown, or pink in color; it is one of the most common and inexpensive sedimentary stones used as flagstone. It is strong, abrasion resistant, and has a natural non-slip surface, making it an exceptional flooring material. It is colorfast and can be used indoors or outdoors.
