A picture post card view of the entrance to the Bear Gap Mine Tunnel of the Lykens Valley Coal Company, which went approximately 3300 feet into Coal or Thick Mountain in Dauphin County, Pennsylvania. This effort was made in order to reach the last vein of coal. At the end of the tunnel, an air hole was made to the surface. This air hole became somewhat legendary in that miners and school children from Gratz and Lykens Township used it to access the Bear Gap Tunnel and get to the Lykens side of the mountain.
The photo looks north. The caption on the photo states: “Bear Gap Tunnel – Short Mountain, Lykens, Pennsylvania.”
