The coal towns, or "coal camps" of Fayette County, West Virginia were situated to exploit the area's rich coal seams.  Many of these towns were located in deep ravines that afforded direct access to the coal through the hillsides, allowing mined coal to be dropped or conveyed downhill to railway lines at the valley floor.  Many of these encampments were set up as company towns, and when their mines closed, the towns vanished.  A few, like Thurmond, West Virginia, have survived in a reduced state.
