Added to the National Register of Historic Places October 15, 1966.
The Miami and Erie Canal Deep Cut is a well-preserved long section of the Miami and Erie Canal near Spencerville in western Ohio. The 6,600-foot (2,000 m) segment represents one of the major construction efforts of the canal; in order to avoid using locks to go over a ridge, the canal was dug deeply into it, far more than the 5-foot (1.5 m) depth of the canal itself. Workers dug the canal bed up to 52 feet (16 m) into the blue clay ridge that separated the St. Marys and Auglaize River watersheds. It is a United States National Historic Landmark. The cut is owned by the state and managed jointly by Johnny Appleseed MetroParks and the Heritage Trails Park District as Deep Cut Historical Park, with multi-use trails and a picnic area.(read more...)
