I’m pretty sure that’s just the imprint of a kid’s hand grabbing fingertips of snow as described above. I tried it outside and it makes a very similar pattern depending how wide you stretch your thumb (my snow is too powdery to get a good picture).
Any tracks close to that shape like an aquatic mammal all have 5 toes, and birds pretty much all have 3 toes pointing forward. Fake.
If it actually is a single track, then it is absolutely a fake. No animal could leave a single isolated print like that. As has been mentioned, raccoons, beavers, and most other pawed mammals have five toes. Birds have three toes pointing forward.
I think they have an infestation of ostriches. The cold weather kind.
I saw some odd tracks at my house last winter. I live high in the Rocky mountains. I was just taking the dogs for a walk down our ‘road’. Something had leaped 3 feet up and 4 feet forward into the snow. Left a tail mark too. Thinking Mountain Lion/Cougar. Not unheard of but a bit rare. We mostly get Black Bear and so many moose in the yard that I stopped naming them.
Moose are cool. They aren’t afraid of anything, and for good reason. AND they ‘mow’ the grass over my septic field so win-win.
The track as photographed is bigger than when it was created. Look at the boot print. There’s partial melting and refreezing. During the period of melting there was some sublimation of the snow (snow to water vapor) and the size of the prints increased.
Also, the digit points of the middle track indicate each digit curled inward as it pressed down. Animals don’t do that. But human hands do when one curls the fingers while pressing into the snow. The rear part of the track shows the thumb curl distinctly. Lastly, there are two “mounds” on either side of the middle track, as though placed there to reshape the track.
