Georges Creek Valley is located in Allegany County, Maryland along the George's Creek. The valley is rich in wide veins of coal, known historically as the "The Big Vein." Coal was once extracted by deep mines but is only mined today through surface mining. The Georges Creek Valley was once a major center for the US coal industry. A series of small mining towns were founded along the Georges Creek Valley in the nineteenth century when coal was discovered in the region.
