The Potomac bluestone was added as the official rock of Washington DC in 2015 in Law 20-220, the "DC Rocks, So We Need One Act of 2014"
Sedimentary and igneous rock layers recrystallized to become the metamorphic rock of the Piedmont. Quarries along Rock Creek, and at Little Falls, Maryland, provided Washington, DC with building stone from the Piedmont’s Sykesville Formation, also known as Potomac Bluestone (Gneiss). Foundations of the White House, Capitol, and Washington Monument, along with buildings like the Lock Keeper’s House and the Old Stone House in Georgetown were built with the Sykesville Formation.
In 1890, Rock Creek Park became one of the first federally managed parks. Since then, citizens seeking recreation and re-creation in nature have sought out this 1700 acre park. As an administrative unit of the U.S. National Park System, Rock Creek Park now manages Meridian Hill Park, Dumbarton Oaks Park, Montrose Park, Old Stone House, the Francis Scott Key Memorial Park, Fort Stevens, and many more sites throughout D.C. Each of these parks has significant history of their own; find out more by visiting the National Park Service website http://www.nps.gov/rocr/
