Comments on the geologic information

  • Geologic Description = Cretaceous rocks contain bentonite beds as thick as 1.5 meters (5 ft). Beds that appear to be composed of nearly pure bentonite are locally present in the Colville Group and in the Niakogan Tongue of the Chandler Formation and the Ninuluk Formation of the Nanushuk Group. Clasts of bentonite are common in rocks of the Colville Group.
  • Age = Early and Late Cretaceous
