Over 200 fascinating postcard images show early coal mining in McDowell County and how it progressed throughout the years. Coal was discovered in McDowell County, located in the Billion Dollar Coalfield of southern West Virginia, in 1748, but it was not explored or mined until the early 1800s. Mill Creek Coal & Coke Company shipped the first railroad car of coal in March 1883 via the Norfolk & Western Railway. By the early 1900s, hundreds of mining companies dotted the county's landscape. The coal from McDowell County fueled the nation's home heating and steelmaking businesses and both world wars. As the coal industry developed, the local population grew; by 1950, the county had grown from a few hundred people to more than 100,000. .
