The hematite is red to black, oolitic to massive, earthy to hard. It was associated with goethite and an array of phosphate minerals (Chamberlain, 1877, Hawley and Beavens, 1934; U.S.G.S., 1976; Paull, 1977). It was mined along Iron Ridge near Mayville in Sec. 12 and 13 T.11N R.16E until the mid-1970's. Beds up to 55 feet thick occurred.
