As I said earlier, it does seem that someone has an axe to grind.
I'm not familiar with that area, but John makes a good point about maps. Many "trails" that appear on topo maps are not detectable at all in the woods; and also there are many trails in the woods that do not appear on any maps. An "armchair map reader" can reach a lot of wrong conclusions about what's really out there on the ground.
Also, a good point about being close to something and not seeing it in dense woods. I've done a bit of wilderness SAR (mostly grid search line stuff). We teach that to get really good search coverage when looking for clues such as dropped items, you should be able to see the feet of the next searcher in line. But that's rarely practiced thoroughly; in dense woods that requires searchers to be quite close together, and greatly reduces how much area a team can cover. So there's usually a compromise with search coverage and search efficiency. So it's easy for a search team to miss something in dense woods. No scale on that map, but the "location found" dot looks to be at least a couple hundred feet off that "trail" on the map. At a couple hundred feet in dense spruce, even a blaze orange tent would not be detectable.
