BROAD TOP COALFIELD

Okay, so this isn't exactly Western Pennsylvania, but it's still bituminous, or at least semi-bituminous, which is superior. Actually the Broad Top Coalfield is a geological anomaly, not being connected with the main Appalachian coalfields at all, but existing as an isolated coalfield in the southern part of Pennsylvania. The coal there is considered low-volatile, or "smokeless." The three coal seams that are mined in the Broad Top Field are the Fulton, which is actually the Clarion seam, the Barnett, which corresponds with the Lower Kittanning seam, and the Kelly, a seam that is actually a continuation of the famous Upper Freeport seam. Coal mining in this coalfield dates back to colonial times, expanding to large-scale commercial development in the 1850s. After a century of relentless extraction of coal, most deep mines closed in the 1950s. Strip mining had become the norm in the Broad Top Field by then, but there are no active coal mines in the Broad Top Coalfield at this time, according to local residents, one of whom said that there was "as much coal left as was taken out." The reason given for it not being mined is that it was too low, but one day the technology and price will be right to reopen the coal veins of the Broad Top Field.

Update: In 2020 I looked on Google Earth and I could see a few new coal mines in the Broad Top Coalfield. Since the thermal coal market has constricted so much, I assume that these are mining coal for metallurgical use.
