Getting back to the original guts of this thread for a minute. In particular, the question about whether or not the "beds" were made by bears or Bigfoot. I and others have found several black bear "nest" or beds out in the open and in limestone caves, crevices in other bedrock that had been uplifted, leaving voids created by softer beds of sediment be removed by erosion, in the hollows of both large dead-fall and living trees in river bottom lands. In every case, the fact that bear made those beds was evidenced by the distinctive claw mark left by their raking, piling and arranging the bedding material. Occasionally bear hair was found and later confirmed under the microscope.
A little over a year ago, two others and I found, painstakingly examined and photographed a very recently made, but unused bed of duff in a large section of remote lowlands in South Arkansas. That bed was made by a Bigfoot, and there was evidence to confirm that. Apparently when the Bigfoot made the bed, he/she was confident the location was safe and secure from prowling humans. Humans seldom entered that large section of land because of its remoteness and the fact there is only road into it, and that entrance is controlled by the land owner and a state agency. The landowner, another investigator and I made the trip in on ATVs through cypress lowlands - made it fine going in, got hung up and stuck coming out - to look for sign of a BF that had been harassing hunters on the fringes of the area.
The details and photos of that BF bed were posted on a hunting forum. I'll see if I can bring it onto this forum.
