The Great Dismal Swamp, approximately fifteen hundred square miles in area, is shared by Virginia and by North Carolina. It is noted for its dense tropical growth, its fur-bearing game (particularly, black bear), its massive timber varieties and its disorderly plant vegetation. Juniper trees, sometimes called red cedar, and cypress trees are abundant around Lake Drummond in the Great Dismal Swamp. The swamp is more easily accessible from Virginia than from North Carolina. In addition to the above natural wonders, there are numerous mineral springs, canyons, mountain peaks and deep gorges. Virginia has nine State Parks including Douthat State Park (near Clifton Forge), Fairystone State Park (near Bassett and Martinsville), Hungry Mother State Park (near Marion), Seashore State Park (near Cape Henry), Staunton River State Park (near South Boston and Halifax), Westmoreland State Park (near Montross and Fredericksburg), Claytor Lake State Park (near Dublin and Radford), Prince Edward Lake State Park (near Burkeville) and Pocahontas Memorial State Park (near Richmond and Petersburg). The Breaks Interstate Park controlled by Virginia and Kentucky has scenery so similar to the Grand Canyon that it is often refered to as "The Grand Canyon of the South." The Virginia area of the Breaks is located in the northern part of Dickenson County. Virginia also has a prominent National Park, Shenandoah National Park, established in 1935, which consists of approximately 193,000 acres. This park includes the beautiful Skyline Drive. Cumberland Gap National Historical Park is located in parts of Kentucky and Tennessee as well as in Virginia. _Rivers and Lakes_ Because of the varied topography, there are many swift streams which are available (although not yet completely utilized) for water power. Virginia has parts of eight different river systems within its boundaries. They are the Potomac River (including its chief tributary, the Shenandoah), the Rappahannock River (including its chief tributary, the Rapidan), the York River, the James River (including its tributaries, the Chickahominy and the Appomattox), the Meherrin, Nottoway and Blackwater Rivers (the chief tributaries of the Chowan River in North Carolina), the Roanoke River (including its chief tributary, the Dan), the New River and the Holston, Clinch and Powell Rivers (the chief tributaries of the Tennessee River System). These rivers furnish excellent waterpower and drainage.
