This one is hard to sort out. Moffitt-Sterling is along the Monongahela River in southern Greene County. The patch town is actually up on a hill above the river. Moffitt-Sterling Gas Coal Company formed on Dec. 30, 1920. In 1926 that firm operated the Moffitt Mine. In the same vicinity there was another firm named Mapel-Sterling (sometimes spelled Maple) Coal Works, which owned the Dunkard No. 1 (Sewickley seam) and Dunkard No. 2 (Pittsburgh seam) mines. By 1936 these were owned by the Sterling Fuel Co. and employed 137 people that year. Later Mapel-Sterling ran the nearby Hilltop No. 1 mine, which at one point was also operated by Hilltop Coal Co. See what I mean by Moffitt-Sterling area mines being hard to sort out?
