Finding this den was a jewel it may have not contained any bones or DNA evidence but its hidden from the rest of the world in an area so very few would ever go. The entrance to the den is fairly large it drops down into a room. More then likely a cougar or bear used it at one time or still does but with all the noise we make we scare everything away except for the Squatch himself. Other Cryptozoologist often wonder where a Bigfoot like creature might hide? Well if you want to study primitive roots probably ancient cave dwellings like these which provide shelter from the elements in the wilderness where food is abundant.
