This tour has been postponed to May 23. Join us for a leisurely walk along the Seneca section of the C&O Canal (about one mile total on the mostly level gravel towpath). You’ll get the chance to see and learn about the Seneca Aqueduct, the ruins of a stone-cutting mill, and two kinds of canal locks. This class is offered in conjunction with the May 2 lecture (see class #300), but participants need not have taken the lecture. We will be watching out for cyclists!

Participants are responsible for their own transportation.  We will meet at Riley’s Lock on the C&O Canal in Poolesville, MD; parking is available in a gravel lot at the end of Riley’s Lock Road, off River Road (left turn from River Road, approx. 9.3 miles from Potomac Village at intersection of River and Falls Roads).  There is not an actual street number, but Google Maps recognizes Riley’s Lock.  Gather at the rear of the lockhouse. (Porta-john at the parking lot.)
