It's the dead of winter & the Last Alaskans move through the icy Arctic. Heimo still needs a moose, while the Seldens embark on the next part of their trapline journey. One of the last of the Last Alaskans - 20-year-old Charlie Jagow - is introduced.

The sun returns, signaling late winter in ANWR. An unwelcome intruder threatens Tyler & Ashley's success. Heimo & Edna say a final goodbye to their oldest cabin, while Charlie meticulously builds his very first and reflects on his future in the bush.

As the Arctic Circle's short summer nears its end, The Last Alaskans begin their preparations for another winter on the trapline.

As The Last Alaskans settle in to their fall routines in preparation for winter's trapping season, several visitors make their way out to the cabins. Heimo and Edna roll out the red carpet for their youngest daughter Krinn and new grandson Colby.

The Last Alaskans are finally home - some for the winter, others for a much shorter stay. Heimo and his youngest daughter Krin hunt for caribou. The Seldens have helpful visitors and an exciting announcement. Bob arrives back at his cabin.

As the seasons turn, the Last Alaskans are gearing up for trapping season. Heimo's newest cabin may have already fallen victim to a marauding bear. Tyler and Ashley are in full swing building a new home for their growing family.

With winter fast approaching, The Last Alaskans set out to hunt moose. Heimo and Edna team up together. Tyler draws on gut instinct to stalk an elusive bull. And Charlie soon discovers why the area is called "Starvation Country."

With winter just weeks away, The Last Alaskans are desperate to fill their smokehouses. The Selden's all pitch in to haul home Tyler's recent moose kill. Heimo and Charlie both worry they might not have meat for the winter months ahead.

Winter in the Arctic Refuge usually means go time for The Last Alaskans but this year low snowfall is slowing them down - snow machines and dogsleds are useless in these trail conditions.

As winter tightens its grip, the days grow shorter for The Last Alaskans and that means less daylight for checking traps. Heimo and Edna's fur count is way down and when wolves invade their traplines, Edna takes matters into her own hands.

Winter loosens its grip on the frozen north and The Last Alaskans celebrate the sun’s reappearance on the horizon. In the Season 3 finale, big changes are on the horizon.

Heimo stalks his best hunting grounds and Tyler tracks caribou as the pressure is on to get a big kill before the harsh Alaskan winter takes hold. Charlie inspects his traplines but damage from summer wildfires puts his season in jeopardy.

Hidden deep in the wilderness of Alaska is the toughest town in America: McCarthy. Locked in winter’s grip, the 42 souls who are brave enough to live here must battle the elements, and each other, to maintain their pioneer way of life.

The last days of winter bring change. The future of town lies in the balance. Jason races the melting river crossings to reach his crashed airplane. Jeremy tests his nine-year-old son with a risky solo dog sled run through the woods.

As seasons change in McCarthy, the town is haunted by its darkest day. The icy ground thaws into a quagmire, and old-timer Tim Mischel is marooned at his remote cabin. Neil and Jeremy’s frozen truce is set on fire.

Spring means locals can finally reach the outside world to resupply. Jeremy walks a bull calf home through bear country and faces off with a hungry black bear. Jason’s brother Eric departs town for a new job, leaving Jason to face the wild alone.
