Vaise traced the history of the river and surrounding area from the time of its earliest native American inhabitants, through the arrival of European explorers and settlers, and ultimately to its significance in establishment of the national capital of Washington. He also explored the role of the river across time as a place for commerce and recreation. Anacostia Park is a 1,200 acre reserve on the river at 11th Street SE.
