The Cuyuna Range iron mining era began in 1907 when the Roger Brown Ore Company developed the Kennedy Mine north of Crosby. The mine began stockpiling in August 1908, but the lack of convenient and economical transportation slowed Cuyuna Range mining operations. In October, Cuyler Adams, in partnership with two Duluth attorneys representing the Soo Line Railroad Company, announced the incorporation of the Cuyuna Range Railroad Company. To compete with other railroad lines, the company contracted with area mine owners to ship half of their iron ore at 65 cents per ton, reducing the cost to 60 cents per ton after 2,000,000 tons were shipped. The Soo line, believed to have fostered the venture, purchased the Cuyuna Range Railroad for $500,000 in March 1910. As the railroad reached the Kennedy Mine and approached the newly platted townships of Crosby, docks in Superior, Wisconsin, were built to handle 1,500,000 tons of iron ore a season. The Crosby Depot became the western terminus of the railroad, sparking a major economic boom for central Crow Wing County. In recent times, the depot became the Cuyuna Range Historical Museum.
