Summary

Description

Government Island is an historic 18th and 19th century quarry site that provided Aquia sandstone for the construction of the White House and the U.S. Capitol building. During George Washington's Presidency, Government Island was purchased by Pierre L'Enfant on behalf of the federal government in 1791 to provide stone to build the nation's new capital city - Washington, D.C.

"Tool marks" are a type of sole marking in a sedimentary rock.
