One of my favorite pictures of the tunnel. I am holding a bike rim and wearing a headlamp. My friend triggered the flash just behind my lower back. The fog is a temperature inversion at the entrance of the tunnel; it was 102 degrees outside of the tunnel and about 50 degrees inside, and humid.
Holes were cut into the floor to extract equipment from the basements. it was interesting to see the I-beams extending through all the levels of Studebaker.
This picture shows the challenges of moving around underground in the base.
