Acres after map date: General Area of mining acres shown:

Several small surface mines. The pits were likely very small, and of the 110 acres shown on the accompanying map, only a small percent may actually be mined. One of the small surface mines operated in 1932 (when the Coal Reports did not list mines producing less than 1,000 tons per year). The mine was reported as Dahlgren Coal Company, operated by L. L. Tedder. This is one of more than 6 mines in the vicinity, all of which were probably quite small in area and very low in total production.
