This is a guidebook for whitewater paddlers from metropolitan Washington DC, Baltimore and surrounding areas. It includes the very small creeks that are not in existing guidebooks, as well as larger rivers like the Potomac and Shenandoah. The coverage includes most of Maryland, northern Virginia and nearby parts of Pennsylvania and West Virginia. In addition to maps that help readers locate the streams, GPS coordinates are given for all of the put ins and take outs. Historical and geographic snippets are included in boxes.
