Building stones of our Nation's Capital

The buildings of our Nation's Capital serve as an unusual geologic display, for the city has been constructed with rocks from quarries throughout the United States and many distant lands. Each building is a unique museum that not only displays the important features of various stones and the geologic environment in which they were formed, but also serves as an historic witness to the city's growth and to the development of its architecture. This booklet describes the source and appearance of the stones used in Washington, D.C.; it includes a map and a walking guide to assist the visitor in examining them.

Gypsum and anhydrite in the United States, exclusive of Alaska and Hawaii

The distribution of gypsum and anhydrite in the United States (exclusive of Alaska and Hawaii) is shown on the accompanying map. In addition to mines, open pits, and occurrences, the map shows the outcrop patterns of gypsum-bearing fomations and other outlines of the important evaporite basins in which gypsum and anhydrite might be found. Because of the numerous factors involved in determining the amount and purity of the calcium sulfate present in each deposit, no attempt was made to rank the deposits according to size. Deposits of gypsum and anhydrite have not been differentiated on the map.
