1961 Map of Rochester

About this map

The vast expanse of Lake Ontario dominates this mid-century survey, illustrating the complex international maritime boundary between Canada and the United States. The coastal landscape is defined by its deep bays and prominent points, from the sprawling Henderson Bay and Mexico Bay in New York to the intricate shores of Prince Edward Bay in Ontario. Inland, the map reveals a post-war infrastructure booming with the heavy line of the New York State Thruway cutting across the southern tier and the extensive rail network of the New York Central connecting established industrial centers. The drainage patterns of the Genesee River, Seneca River, and Oneida River emphasize the region's historic reliance on water for transit and power. To the southeast, the protected marshes of the Montezuma National Wildlife Refuge stand in contrast to the growing residential and commercial grids of the larger settlements.
