Where is anthracite coal?

Anthracite is mostly found in east-central and northeast Pennsylvania in highly folded rocks. Most veins are difficult to mine as they are at high angles and not in flat deposits. This coal was formed during the carboniferous (Pennsylvainian) era ~ 300 MYA.

Small deposits are also found in Arkansas as well as China...but the vast majority is in Northumberland, Schuylkill, Carbon, Lackawanna and Luzerne Counties of Pennsylvania
