Yesterday, Monday the 15th.
It looks like they cleaned nothing up; lots of trash including full rolls of roofing paper. Inside in the back you could still see the PVC plumbing and red valve handles that were shown in the newspaper pictures. Also there were at least ten one gallon sized zip lock bags full of some gray powder, my first thought was flour or pancake mix but of course then the animals would have already gotten to it so maybe concrete mix?
Yes, it was very, very well hidden. He picked a good spot. If not for the picture they discovered taken from the site it would have been much harder and likely maybe not found at all. If not for the smoke from the fire he lit, even with the picture it would have been very time consuming to locate it.
To locate it, myself and a buddy used only the information we discussed here and saw on the news but of course it didn't go very far. A combination of clues progressively lead us to it and even when we obviously got very close due to the recent activity very near the site, it took some work to actually locate it, partly because of tracks probably due to the SWAT teams searching and covering the area and detectives afterwards.
It looks like the majority of people were flewn in and out as the trails fade significantly out as you get further away. We were also believe that we were able to determine the helicopter lift area which was maybe 150-200 yards from the bunker (fort).
Once within say 150' from one direction, it's get much more obvious that we were in the right location. He had a work area near the bunker for cutting this timbers along with a stack of maybe eight ready to go. There was very recent sawdust so we guessed that he was probably working on it right up to the time it he went into hiding. He had a small dam at the stream which I assume he used for washing.
I found the work area first and a few moments later my friend who was maybe 50' below me in elevation spotted the bunker opening from a distance. But only because to top is now cut open. Back when it was intact it would not be easy to find unless very close to it.
Even so, I am now more convinced that this was a fort done by a poorly thinking man and not a well thought out bunker done by a military thinking man. This for a few reasons. A big one is failure to cover up his work near the site and that the openings were square rather than more natural. He relied more on covering evidence of making his way to and from the site rather than the site itself. If his opening was more concealed and the cut logs not left out then someone accidentally finding the area, however unlikely, would have thought it strange but could still have written it off to hunters, foresters, kids etc. These are just my opinions though.
I think that's about it. I'll post some more pictures later.
