Comments on the geologic information

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