Alaska's Deadliest

North America does not get much colder nor any darker than Alaska in winter. It's not a place you mess with, unless you have got a wild side. As winter breaks, carnivores emerge on Alaska's wide open spaces, leaving prey animals no place to hide. Wolves chase caribou with ferocious intensity, brown bears battle for rights to a buffet and wolverines make short work of prey 100 times their size. Alaska's deadliest thrive in one of America's last wild frontiers.

Alaska's wild waters are home to some of the deadliest seafarers on the planet. Shores of open ocean create a path for giant hunters like orcas and salmon sharks, and its deep-water channels hide tiny ocean terrors.
