I found and bought a fantastic photo of the LCC-1 Sno Train on eBay yesterday. I’ve seen this photo on the net, but didn’t have any verifiable background to the source.
As part of the photo purchase, it comes with a typed description (metadata) about the photo. This photo was captured on 25June55 at Camp Century, Greenland. Camp Century was part of Project Iceworm. The barrels mounted to the side of the freight cars are Petroleum, Oil, and Lubricants (POL). The base was abandoned and decommissioned in 1967. Historic photographs like this are available from Coots Imagery and Historic Images to name a few.
