An interior view of the cooling pump room of the Lykens Power Plant of the Lykens Valley Coal Company, Short Mountain Colliery, Bear Gap, Dauphin County, Pennsylvania, about 15 June 1922, when the plant was in operation.
The power plant was constructed to save money on power generation and when completed provided a cheaper and more efficient form of power for the colliery. In addition, surplus electricity was provided to the Williamstown collieries, and for Lykens Borough and the town of Wiconisco.
