The Georges River Land Trust and Montpelier: General Henry Knox Museum are co-sponsoring three free events focused on the history of the canals along the St. George River in Warren and Searsmont.

On Monday, Aug. 30, two guided walks will be held. The first walk, lead by Sophia Mendoza, education coordinator at Montpelier, will meet at 10 a.m. at Payson Park in Warren and proceed along the trail toward the old Powder Mill Road. The second walk, lead by David Getchell Sr., a volunteer with the Georges River Land Trust, will meet at 1 p.m. at the canal path in Searsmont.

On the National Register of Historic Places, the canal at Payson Park covers 18th-, 19th- and 20th-century history and yet remains relevant to 21st-century students and schools. Traveling along the berm, walkers will see the ruins that were part of the lock built by Henry Knox in 1794-97.

The 1.5-mile Canal Path in Searsmont is Georges River Land Trust’s first interpretive trail section of the Georges Highland Path. The walk follows along the St. George River south from Ghent Road and features informative displays about the historic Georges River Canal, parts of which are still in evidence. The trail also offers a self-guided tour that details the sustainable forestry management practices of Robbins Lumber, the landowners who host the trail. For directions to Payson Park or the canal path in Searsmont call 594-5166.

Knox’s efforts in constructing the canal will be the subject of the third event, an evening lecture by Mendoza in the Oval Room of Montpelier on Wednesday, Sept. 1 at 7 p.m. Space is limited for the evening lecture, so call 354-8062 for reservations.

The General Henry Knox Museum is a nonprofit organization dedicated to maintaining Montpelier as a museum and fostering a greater understanding and appreciation of General Knox’s life and times, and providing educational, cultural and community events. The Georges River Land Trust works to conserve and steward the natural resources and traditional character of the Georges River watershed region for the public benefit. The watershed extends from Montville in the north to Port Clyde and Cushing in the south and includes streams, ponds, lakes, wetlands, farms, hills, mountains, blueberry barrens and forest, as well as a rich tidal estuary of salt marsh, clamflats and productive fishing grounds.
