The Coal Pits consists mostly of wide open passages composed of thick sections composed of coal vein and grey rock, with wooden beams blocking off certain areas or providing platforms to stand on. The long tunnels are frequently dead ends which necessitates lots of backtracking to progress further, unless digging or explosives are used.
