Alt Text Map of Chesapeake and Ohio Canal National Historical Park, which traverses Washington, DC, Maryland, and West Virginia. The park area is indicated in pale green, and each state is a different light pastel color. Extended Description Hundreds of sites, features, roads, highways, bodies of water, and towns are labeled in this map. Mileposts are numbered from bottom to top, so this description will use that structure to move from Washington, DC up through Maryland and into West Virginia. Visitor Centers, parks, and features associated with the Chesapeake and Ohio Canal National Historical Park will be listed using the Mileposts for reference. Milepost 0 is near Tidelock, Lock 3, and the Georgetown Visitor Center in Washington, DC. The Canal winds up past Cabin John Creek, Seven Locks, and Carderock, which is just past Milepost 10 in Maryland. Sites that follow include Marsden Tract, Anglers, Great Falls Park, Great Falls Tavern Visitor Center, and Swains Lock.
