Here is a link to the video for educational purposes. Please note that the video is showing us only a portion of the shelter and no size comparisons. The still on my home page is very telling.
From what is seen here I can't call this anything other than man made. We have a classic shelter built along a fallen tree/log. Sticks are propped up along the log on both sides causing a tapering a-frame. After this step there can be a cross supports inserted beneath the log which can be filled with debris for trapping heat. Then pine boughs or leaves are piled up along the sticks causing a cover for the a-frame. More sticks are leaned against the debris in order to hold it in place. After that it appears the occupant had a leak where bark was placed along the spine to deflect rain. This suggests the sticks were not long enough to overlap allowing a reasonable down flow for rain thereby causing water to drip down on the occupant instead of flowing along the sticks to the ground.
Please don't get me wrong! I think Sasquatch/Bigfoot do use structures of a sort but they would be more natural and less uniform in construction. It is my opinion that they are creatures of opportunity when it comes to shelter. They know their areas and they know where to find it. In their environment they have less need for uniformity and organization as provided by their environmental examples. This is all why I suspect this is a man made shelter check out: The NatureSkills website.
