Over and under the snow

Over the snow, the world is hushed and white. But under the snow lies a secret world of squirrels and snow hares, bears and bullfrogs, and many other animals making their winter home under the snow. This beloved nonfiction picture book exploring the subnivean zone reveals the tunnels and caves formed beneath the snow but over the ground, where many kinds of animals live through the winter, safe and warm, awake and busy, but hidden beneath the snow.
