Eighteen miles south of Washington D.C., on the banks of the Potomac River, lies a peninsula known as Mason Neck. Here, on February 1, 1969, the U.S. Fish and Wildlife Service created the first national wildlife refuge established specifically for the protection of our nation’s symbol, the bald eagle.
