ICPRB has map sets for the upper Potomac River and its surrounding trails. These maps are a terrific way to get to know the Potomac from Shepherdstown, W.Va., to Potomac Park, Md. Recreational fishing, biking, hiking, kayaking, canoeing, camping, parking, and public boat launch information is included. For the history buffs, there is information about parks and historical sites to satisfy your curiosity.
The maps are printed in color on a tear-proof, waterproof polyester material. Copies are $5 for the set, including postage.
This set of maps, produced by ICPRB with the help of many government agencies and non-profit groups, has been out of print for several years. However, the maps have been updated and digitized and can be downloaded for free. The 10 maps cover the river and C&O Canal National Historic Park from Washington, D.C., to Opequon Creek, a short distance upstream of Shepherdstown, W. Va.
