Description: An investigation was made to determine the location and extent of large blocks of strippable coal in Montana. By using published reserve data as a base and adding drill hole data contributed by companies owning or leasing coal lands, 37 deposits containing 12.7 billion tons of strippable coal were delineated. All strippable deposits are in the Fort Union region of eastern Montana.
