How about from this angle? Don't forget, you can click on the photo and make it larger at Flickr.
They are tunnels made by rodents! The extended mark in the upper part of the second picture is the roof of a tunnel made by the creature who popped out of the snow and went back under a foot later. It is risky being out on top of the snow - birds can pick off little voles who linger too long.
I'm not quite sure how the vole got from the obvious hole on the right to the tracks beside it, unless he was jet-propelled and flew through the air a little.
I'm not really sure in what direction this vole was travelling. Does he drag through the snow as he leaps forward or as he lands?
I think those are dog tracks going through the middle. On the right is the roof of a tunnel. And tracking through it are the distinct prints of some bold rodent who managed to not drag through the snow at all. Did he have long legs? Fun stuff.
