 Today, the Accokeek Foundation partners with the National Park Service to steward 200 acres of Piscataway Park which covers, in total, approximately 5,000 acres, from Piscataway Creek to Marshall Hall on the Potomac River.An effort that began out of a desire to "preserve the view," in the end has preserved much more.The full conservation area protects a wealth of environmental, cultural, and historic resources, from wetlands to farms to nationally significant historic sites.
