Le Woolly Mammoth Sighting

As always I'm a skeptic and most likely with reason.  First, as it always seems with cryptozoological footage, the film is blurry with no definition, but maybe that's on account of the rushing waters producing a fine mist combined with the frigid temperature.  Second, it seems a bit too small for a mammoth, but maybe it's a lost baby.  However, I believe it's most likely a species of brown bear with a dead fish in it's mouth, which attributes for the 'trunk' of the blurry animal.  I do leave a margin of error due to the fact I don't know everything especially in concerns with the stride differences between the two animals. I'm more apt to believe, though, that it's Ron Jeremy doing an extreme Polar Bear Club skinny dipping.

What's everyone else theory on this?
