About this map

Lake Ontario and the St Lawrence River meet at the head of the Thousand Islands in this mid-1980s planimetric study of Jefferson County. The map details a landscape where international water boundaries divide Wellesley Island and Grindstone Island from their Canadian neighbors, and the shoreline is heavily shaped by state conservation efforts. A visible Old Railroad Grade north of Limerick and Rosiere provides a trace of former industrial transport through the region. Inland, the map documents the rural settlement patterns at crossroads like Depauville, Smith Corners, and Clayton Center, while identifying extensive protected wetlands such as the Perch River State Wildlife Management Area and Ashland Flats State Wildlife Management Area. Numerous island features, including Carleton Island and Picton Island, are charted along the river's American Narrows.
