Kittanning Coal

Kittanning coal refers to coal seams in the Kittanning cyclothem of the Pennsylvanian Epoch. The Lower Kittanning is coal number 5, while the Middle Kittanning is coal number 6. These were and are economically important coal seams in the Appalachian area. The Middle Kittanning is at about surface level in the valleys of Monday Creek and Sunday Creek in southeastern Ohio, but become much deeper going east. Many villages in southeast Ohio grew up around the mining of the Middle Kittanning. Many of these are known as the "Little Cities of Black Diamonds."
