2021-1-21  It is only mined at places where the gypsum is near the surface, while at others it is buried by more than 1200 feet of rock (see map below). Gypsum beds are seldom more than 20 feet in thickness. Near Grand Rapids, gypsum of the Michigan Formation are mined extensively, for they are very near the surface in that area.
