An official Path Through History Site! For more than half a century, the 77-mile long Black River Canal played a central role in the life of the North Country. An engineering marvel of the 19th century the canal had 109 locks. Abandoned entirely in the 1920s, the former canal path is replete with stone locks and other evidence of the man-made waterway.The Hemlock Mercantile houses a pictorial history of the Canal and surrounding communities and other static displays. It also houses the Hemlock General Store that features gifts for young and old, books and canal memorabilia. An original one-of-a-kind canal warehouse was restored. This warehouse was used for mules and storage during the active years of the Black River Canal. The warehouse also houses an interactive pulley system that shows how different pulley set-ups distribute weight and there are two miniature crane systems that will be hands-on to allow the visitors to put supplies on a canal boat. In addition there is a full size working canal boat rudder with a moving deck. A handsome canal walkway, lined with early 20th century street lamps, now extends South from Main Street and State Rt. 12 junction. Visit website for further information.
