I believe that these fresh tracks in the snow are from a coyote.
As you can see in this photo, the coyote was taking advantage of the old snowmobile track for easier walking. Note the clear blue sky with just a few fluffy clouds.
It was -12 overnight but with the sun in the afternoon it was only -8, with a light wind it was a perfect day for the skis. I was out for 80 minutes and made four trips down this little hill.
