Interesting clip of what seems to be a very old footage of a Sasquatch messing with the water. It's not clear if the Bigfoot is trying to catch a fish or cleaning itself.
There's no additional information on this except that it was just uploaded by "videohistorytv" today. The channel contains other video clips from history such as the Space Shuttle Launch disaster to Martin Luther King "I have a dream" speech.
The video description says it's a "Footage of what was, and still is believed to be 'Bigfoot'".
Update: Here's the full version. In color!
