Here's a coolest of cool thing about the Last Frontier - the whales. One type is the bowhead whale. These giants (adults can be 60 feet and weigh in at 100 tons) hang out in the Arctic Ocean and don't migrate south to feed like most whales. Instead, with over a foot of blubber as padding and a massive head (perfectly suited for ramming ice), they swim north in April.
Bowheads are black with a white spot on their snouts, and their calves or babies are blue/gray. Bowheads have two blow holes and can pop through a foot of ice to breathe.
Unlike other whales, they're not very social, preferring to have pods of three or so buddies while feeding in the spring. In the fall, the buddy number shoots up to fifty.
If they visited Suskeegach, these bowheads could easily explore the bottom of the Narrows as they can dive to 500 feet.
