Spoil and Vertical Shafts:
The tunnel builders hauled out over 200,000 cubic yards of shale spoil from inside the Paw Paw Tunnel through two sets of double vertical shafts and from the northern tunnel approach via the access road leading to the top of the mountain. They later capped off the shafts on top of the mountains and bricked over the shaft openings inside the tunnel. The large ravine or hollow visible here was filled with this spoil. |
