Merrill Park - one of the few coal camps north of the town of Logan - housed the families of the miners of Merrill Coal Mines, Inc.'s Merrill Mine, which they opened in 1921. The company town was along the Guyandotte River, but the actual coal mine was a distance away up a hollow. So Merrill Coal Mines had to shuttle the men to work and back with their own private locomotive. The Merrill Mine produced coal into the 1950's.
