Title: Correlation Chart for Bituminous Coal a MUST
Review: This two-sided "wheel" chart is an absolute must for anyone in the coal business. It is simple to use and small enough to keep in your work truck or briefcase, and large enough to be able to read the information. You simply place the coal seam name on the outer rim directly above the open window on the plate. Then simply read the local name for the same seam opposite each of the local coal fields listed. Listings are for West Virginia, Maryland, Virginia, Eastern Kentucky, Southern Appalachian, Pennsylvania, and Ohio. I really need another one and can't find one anywhere. If anyone knows how to buy a few more, let me know. I'd like to have several for co-workers.
