Stairs descended down into the hill, but it had since flooded and then froze, so I couldn't go past the entrance. For lack of building materials, they used spent fuel drums filled with dirt as structural elements. A common motif on site.
Yes. I was there as part of the environmental remediation crew, running instruments that were scanning for buried debris. It was August, so it only snowed every third day. I have a lot of photos from that site, including inside the facilities. I will trickle a few out now and again. :)
I have some fairly strong political opinions surrounding the cleanup (demolition) of these sites. I was getting paid as part of the process, but I really wish they'd have chosen to preserve them instead. The difference between a historical site and a contaminated site are really about the political lens you peer at them through. I took so many pictures because it was all coming down.
