This is how the area looked before it became a state park in the late 60s.
The railroad built the line through this tunnel is 1893. Can you imagine what the area around this tunnel looked like in the latter days of the 19th century?
To its credit, the park service has done good job in making the tunnel accessible, but not dangerously so.
The acquisition date across the bottom is misleading, I think. I’d date this card to the early 50s. The tunnel, btw, is not 1557′ long…it’s 850′.
