Moshannon Coal District of Clearfield and Centre Counties
The heyday of the Moshannon Distric was the second half of the 19th Century. The main coal seam was the "D", or Lower Freeport, known locally and marketed nationally as the Moshannon seam. This coal was as high as 6.5' in some parts of this coal district. The "D" seam in this area is highly faulted, and it can jump up or down in elevation between 40' and 90' at times. Since most of this coalfield's mining took place so long ago in the 1800s, not many relic coal communities remain intact.
