Note full-size commercial bus at bottom of photo. In 1971, a song titled "Paradise" began to be heard on the radio.

This process continues along parallel strips of land so long as the ratio between the overburden and the coal seam, called the stripping ratio, makes it economically feasible to recover coal. Mining may cease in a particular area, for example, where the coal seam becomes thinner or where the seam dips further below the surface.
