Tracks in snow

I found these tracks on the trail to the business park in the fresh snow, I believe they are fox tracks. It was -10 when I was out walking for 90 minutes.

It was a nice sunny afternoon with very light wind, the fox had gone the whole length on the trail.
I took the trail right to the base of the water tower which is located on the west side of the business park. Just a couple cm of snow, no need for snow shoes.
