The Great Lakes region became a premier center for iron and steel production due to the strategic convergence of essential raw materials, accessible transportation routes, and a plentiful water supply.12

The region’s industrial development was fueled by the proximity of vast natural resources found along or near the lakes' shorelines, including significant deposits of iron ore, coal, and limestone. These materials are critical for steel manufacturing, with limestone, for example, serving as a vital ingredient in steel mills.23

The Great Lakes themselves provided an efficient transportation network into the heart of the continent, allowing for the cost-effective movement of these bulk commodities to industrial hubs in states like Illinois, Indiana, and Ohio. Furthermore, the development of the St. Lawrence Seaway and various canals facilitated the integration of these regional resources with broader trade networks, solidifying the area's status as a major producer of the continent's steel.124
