## History

Matthew Gibson and his son J. Thoburn Gibson discovered iron croppings along the shores of the Hemlock River in 1888, and the Hemlock River Mining Company took over the area two years later when sufficient amounts of iron were found. The company platted the community in 1890. The community was first named Hemlock but was renamed after Amasa Stone, who was the father-in-law of Col. Henry S. Pickands. The name change was suggested by the Pickands Mather Group. The community received a station along the Chicago & Northwestern Railroad and a post office opened here on March 7, 1891.
