is the Palisade Seam. The Palisade was tested in 6 holes during the
1976-1977 drilling program. The seam thins rapidly southeastward from
the outcrop in the vicinity of the Piidwest mines, where it is 3 to 4
feet thick. The thickest coal, 4.60 feet, was found in hole CC-76-2, in
the north central part of the property; the seam thins to the west,
south, and east of this point. The following table shows depth and
thickness of the Palisade in the holes is which it was tested.
