Hibbing is the largest of Minnesota's Iron Range Communities. It sits in west central St. Louis County, about 75 miles north of Duluth. The city boomed in its early years, reaching approximately 20,000 residents by 1910. The massive Hill-Rust-Mahoning Open Pit Mine is the world's largest open pit iron mine, and necessitated moving the city south by approximately two miles during the 1920s. Crossed by two major divides, Hibbing's water drains to three major basins, the Arctic Ocean via the Red River of the North, the Atlantic Ocean via Lake Superior and the St. Lawrence River, and the Gulf of Mexico via the Mississippi River. The city is also famous as the birthplace of Bob Dylan.
