Potomac, a History of the River and the Land

The Potomac River, the dominant geological feature of Montgomery County, has also played a dominant role in American history. It was the first interstate waterway in North America, the spawning ground for the Constitution, and a protective barrier in the Civil War. To travelers today, it is a time tunnel to 250 million years of history. Learn this history from Jim Johnston and then walk along the river to see the Potomac in a new way. The class is offered in partnership with Montgomery History.
