I noticed them the minute I stepped out of the house on Sunday. There was no evidence of humans making their way through the newly fallen snow — but a world of animal tracks greeted me on that still morning.

Tiny bird footprints, the skittering marks of a squirrel or chipmunk, and the more dog-like paw prints of our local fox. Whether hopping, scampering or loping, these animals left their marks.

We think of snow as a covering, coating the verges and leaf piles, making smooth the weed-strewn and the bald-patched.

But snow reveals as well as conceals. It tells us who was here and, if we pay attention, how recently. It’s a blank white slate on which movements make their mark.
