Re the tracks in the snow above, remember I commented on the previous page that tracks often get distorted by snow melting and re-freezing. The "Devonshire Devil" was a famous case of this sort in 19th century Britain. I suspect the tracks above may have been made by a coyote, fox or bobcat bounding through the snow.
In the first vid, those tracks are one day old.
No way a coyote or fox is going to run that distance. Also, how to you explain the large areas disturbed where it looks like a large animal laid down. I think a moose is a more likely option, but a moose print will have a very distinct indentation, as well as disturbance of the snow above as the hooves scrape.
A fox or coyote might jump a fence, but not a moose.
Here are coyote tracks, even running there is no way it spans 5 feet. And all the way up that hill? No way.
