 region. A transitional zone, generally defined as being part of the coalfield region, is the Clifty Area, where the rock outcrops include bituminous sandstone, or tar sands, which have commercial value as paving material.

The biggest concentration of surface mines in this region has historically been along the edges in Hopkins, Muhlenberg, and Ohio Counties. All three counties still contain a very large amount of coal and have active mining, surface and underground, operations taking place. The use of power shovels and draglines were very common in these counties where the coal would lay as close as 60–80 feet from the surface. This is a region that was considered to be the largest producer of coal in the world throughout the 1960s through part of the 80s until it dramatically dropped in the early 90s after the passage of clean air regulations. The largest mining company found during the 30 year span of prosperity became Peabody Coal Company ( Peabody Energy

The reason for this is the demand for Western Kentucky Coal has once again spiked to levels not seen since the 1970s.
