There is very little activity above the snow, but underneath! The field and forest bustle with day-to-day comings and goings. If the snow hasn't melted and settled much (and it hasn't, the winter being so cold), it is fluffy enough to allow light through. Tunnels through the snow are filled with a dim illumination that filters down through the ceiling and walls--blueish in the higher tunnels, but dark gray near the ground.
The mice and smaller animals push the snow aside to make rooms that they can gather in. Here they visit and eat as a group. The younger ones make more tunnels and play hide-and-seek.
But that's for the mice and smaller animals. Foxes may live in burrows, but diving in snow is not for us. If we must leave the dry comfort of home, we explore above the snow, sniffing the air, drinking at the stream where it flows fast enough that it hasn't frozen, finding the last of the dried fruit and nuts clinging to trees or bushes.
My nephew, Loosestrife, spends a lot of time digging for food, but he mostly just gets cold and wet!
