Amasa is an unincorporated community and census-designated place (CDP) in Iron County in the U.S. state of Michigan. The population of the CDP was 195 at the 2020 census.[2] The community is located within Hematite Township.
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.[4] [5]
According to the U.S. Census Bureau, the CDP has a total area of 4.04sqmi, of which 4.03sqmi is land and 0.01sqmi (0.25%) is water.[1]
The Hemlock River, which is a tributary of Paint River, flows through Amasa.
In 2020, its population was 195.
