Icebound

On January 28, 1925, newspapers and radio stations headlined a terrifying story: Diphtheria had broken out among the children of Nome, Alaska, separated from the rest of the world each year for seven months by a frozen ocean. With barely enough antitoxin on hand to treat half a dozen people, the death toll for Nome and other outlying communities could potentially reach into the thousands. With aviation still in its infancy, and one of the harshest winters on record in interior Alaska, only ancient means -- dogsled -- could save the town. In temperatures as low as minus 60, more than twenty men, and at least 150 dogs, set out via dogsled to relay the antitoxin across 674 miles of Alaskan wilderness to save the town from the lethal epidemic.
