Title: Information Sheet, Chesapeake & Ohio Canal National Historical Park, 17 April 2004
Chesapeake & Ohio Canal National Historical Park, Maryland, U.S.A., 17 April 2004
On 17 April 2004, the Botanical Society of Washington, energetically led by Dr. Dan H. Nicolson (Smithsonian Institution), enjoyed a delightful day at the Chesapeake & Ohio Canal National Historical Park, about 10 miles north of Washington, D.C.
We saw many blossoming wildflowers in the spectacular natural garden along the Potomac River.
Dan has been leading his annual plant-appreciation walks for decades.
