About this map

The St Lawrence River defines this landscape, where the international boundary between the United States and Canada weaves through a dense archipelago. On the American side, the community of Thousand Island Park serves as a primary hub on Wellesley Island, connected by roads like Waterson Road and Cross Island Road. The map documents a complex maritime environment of narrow channels and sheltered bays, including Eel Bay and the American Narrows.

Evidence of early 20th-century development is visible in the cluster of island settlements like Grenell and the riverfront hamlet of Fishers Landing. Large tracts of preserved land are already established, including Wellesley Island State Park and Canoe Point and Picnic Point State Park. Across the water in Ontario, the Canadian National rail line runs near Wilstead, while the Thousand Islands Parkway follows the northern shoreline, marking the region's transition into a premier mid-century vacation destination.
