There are some twenty-five words for "snow" in the Inupiaq language. Each word denotes a different kind of snow-fresh powder snow, hard pack, soft snow, very wet snow, or just snow. Such fine distinction is reasonable, for over the centuries, Natives of the Arctic have had to rely on their knowledge of the snow to survive. Now Matthew Sturm has prepared an educational children's book designed to teach a new generation of Arctic residents the importance of Arctic snow cover. Fully illustrated to demonstrate the cycle of the snow cover, Apun covers each phase of the "snow year." Geared towards grades 3-4, this is a must read for elementary science classes.
