Gus Christ photos. Courtesy of the Wilson Creek Museum.
Gus was a Roadmaster out of Ephrata, and a few of his photos have recently turned up. Most seem to date from the 1950s.
Gus had mislabeled the photo as having been the tunnel on the Mansfield Branch, but that is clearly Rock Island Dam in the distance, making this Tunnel 12, before it was daylighted in 1957.
