The Jacobs photo is interesting. I don't know what it is. I grew up in a bear preserve. It does not look like any of the literally thousands of bears I've seen. I don't necessarily think it's a sasquatch either. I think it best to toss it in the "hmmmm" pile. Jumping to premature conclusions **of either sort** is .. premature. I don't understand why people can't leave puzzles as puzzles and instead latch onto answers that can't be defended with integrity.
Recently an animated gif I'd never seen before surfaced. The first pic is new, the middle one seems to be the Jacobs photo we're all familar with, and the third is clearly a bear. That first picture puts the "bear-ness" of the Jacobs photo into greater doubt ... at least for me. It seems to be the same figure but turned a bit.
Like I said, I grew up in a bear preserve. I also hunt them other places. Bears ears are cartilage. They don't grow much so as a bear ages and gets bigger, its ears appear progressively proportionally smaller and smaller. They also seemingly slowly relocate from right on top of the head down to the upper side of the head. As a hunter, if you're after a trophy bear, look for bears that have very small seeming ears mounted relatively low on the head.
So, relative to the photos, if this is a baby bear, the ears should be quite prominent and mounted high. I don't see them. The pictures aren't clear but they are clear enough. Unless this is a very old bear, the lack of prominent ears is a giant red flag.
The other thing that is missing is a rostrum ... a prominent, protruding snout. If the head is turned away so we can't see the snout, the ears should display clearly. If the head is turned to the side so the ears are hidden against the head, the snout should be prominently displayed.
Neither case seems true.
I think calling this a bear demonstrates no knowledge of bear anatomy whatsoever. None.
That doesn't make it a sasquatch. However, putting your "weight" behind a shaky claim it's a bear just to prove it can't be a sasquatch reeks of a wizard-of-oz -style "pay no attention to the little man behind the curtain" ploy.
It's a puzzle best left as a puzzle.
