Muzzle frosted in snow, a cub peeks around a drift (above) as its twin and mother relax. The cubs are about three months old and perhaps a week out of their den in Wapusk National Park. Now, in March, mom is leading her playful clan-with stops for nursing and rest-to the frozen bay where she'll hunt for seal pups born on the ice and eat for the first time in months. As the ice melts, bears lumber inland to wait out summer. Pregnant females dig their dens in fall, starting the cycle again.
