Akira,
The place is a bit spooky. All the closed structures and vessels had a gap blown by dynamite so that when you fall in you could get out. Some of these openings you can see in the images. The animal, I don't know what it was, probably a goat or a sheep, was most likely slaughtered, cooked and eaten by the vagrants that moved in soon after the facility was shut down. When we visited there was no sign of vagrants - fortunately. Martin
