More than half a century after a group of beavers parachuted into the Idaho backcountry, the Idaho Department of Fish and Game has uncovered film footage of the quirky wildlife management moment.

In the 1940s the department was trying to deal with an overpopulation of beavers in some regions when wildlife managers settled on a novel idea. They captured beavers and other fur-bearing rodents, packed them into special travel boxes, attached parachutes and dropped them from a plane into the Frank Church River of No Return Wilderness.
