Nescopeck Creek has coal veins near its source.

These coal veins first appeared 300 million years ago.

As coal veins commenced to be worked, it was not long before the discoverers found out that the supply seemed inexhaustible.

Large, red bluffs are to be seen on both sides and underneath the lake is an immense coal vein.

Small mining operations founded by local residents gave way to large, highly capitalized collieries, capable of reaching coal veins deep underground.

The shaft was 840ft deep, but only the upper series of coal veins were worked.

These were typically in places such as valleys where erosion had exposed the coal veins.

I will remind the reader that in Pennsylvania a coal vein only eight feet wide is considered ample.

Some drillings to find a coal veins has been attempted.

This mine operated in a coal vein that was locally up to 14 feet thick, but only locally.
