April in the Arctic . . . Cold winds send snow clouds scuttling across the sky. Temperatures barely nudge above freezing. But every now and again, The cloud cover parts, The sun shines down, And the frozen world stretches awake. As spring approaches in the Arctic, a mother polar bear and her two cubs tentatively emerge from hibernation to explore the changing landscape. When it is time, she takes her cubs on a forty-mile journey, back to their home on the ice. Along the way, she fends off wolves, hunts for food, and swims miles and miles.
