Washington D. C. is a 68.34 square mile area set aside to serve as the Capital of the United States of America. It is situated near the "Fall Line" separating the Piedmont Province's older rocks, deformed during the Taconic Orogeny, from the Cretaceous and Tertiary rocks of the Coastal Plain. That line is marked by a chain of rapids and falls as rivers, such as the Potomac, move from resistant metamorphic and igneous rocks to softer, less consolidated sedimentary rocks. Most of the city is built on the marshy terrain of the Coastal Plain. Piedmont Province rocks are widely exposed in Rock Creek Park and at Great Falls, a few miles northwest of the District's limits. Coastal plain rocks can be seen at Fort Totten Park and other spots in the eastern part of the city. Outcrops in the District are otherwise sparse. Most of the reported minerals are from ephemeral construction sites and road cuts. However a great variety of building stones are on display in the many government buildings and monuments. Some of the world's best mineral and geology displays are in the Natural History Museum of the Smithsonian Institute.
