A deposit of carbonaceous schist was worked for a poor grade of graphite in the early 1900's. The product was apparently mixed with materials mined from a ferruginous schist a few miles away to make various paints. The location given is "one mile north of Junction City on County Road G", but traces of the long-abandoned workings have been obliterated.
