Schoharie Crossing State Historic Site, also known as Erie Canal National Historic Landmark, is a historic district that includes the ruins of the Erie Canal aqueduct over Schoharie Creek, and a 3.5-mile long part of the Erie Canal, in the towns of Glen and Florida within Montgomery County, New York. It was the first part of the old canal to be designated a National Historic Landmark, prior to the designation of the entire New York State Barge Canal as an NHL in 2017.
