About this map

The Saint Lawrence River serves as the defining international boundary in this 2016 survey, separating the rural north shore of Ontario from the island-dotted waters of New York. The map provides a detailed view of the Grindstone Island landscape, where a network of local roads including Cross Island Rd and Middle Rd connect the settlement of Grindstone with the historic Thurso Cem. This area is characterized by its complex archipelago, featuring named landmasses like Potter Island and Chub Island surrounding the Lake of the Isles.

Inland from the Canadian shore, the terrain is defined by a dense drainage system where the Gananoque River meets various tributaries including Sucker Brook, Mud Cr, and Gander Cr. The cartography captures the intricate shoreline of the Thousand Islands region, detailing points and bays such as Webster Point and Flynn Bay, which have shaped the local maritime and residential character of the borderlands for generations.
