Alexandria Bay serves as the focal point for this Thousand Islands study, situated along the Saint Lawrence River where the international border separates New York from Canada. The map illustrates a dense landscape of riverfront infrastructure and island estates, most notably the landmark Boldt Castle on Heart Island. Navigation is a primary theme of the region, marked by the Pullman Shoal Lighthouse, the Leading Light, and the R.T. Clayton Vessel Traffic Control station at Collins Landing. Inland from the river, the terrain transitions to a patchwork of agricultural lands and smaller settlements like Omar and Alexandria Center. For genealogists, the map is particularly useful for locating several rural burial sites, including the Houghton Cemetery and Saint Cyriel Cemetery. Transportation corridors are anchored by the Thousand Islands Bridge, which links the mainland to Wellesley Island and points north.
