The Arctic National Wildlife Refuge was established by President Jimmy Carter in 1980 under the Alaska National Interest Lands Conservation Act, although much of the region had been under federal protection since the Eisenhower administration.

In this 2009 film, made available on YouTube earlier this year, John Martin and Thomas Morton travel above the Arctic Circle to ANWR, to document the lives of Heimo Korth and his wife, an Alaska Native from Savoonga, who've lived in the federal wilderness more than three decades.

Korth is the last of six non-Native settlers who were granted permission under the law to remain settled in ANWR. Martin and Morton are flown out to Korth's cabin by a bush pilot; from there the two are exposed to a way of life few modern Americans experience or comprehend.

The documentary is over an hour long. Here are a few key times to note:

Part I: First Night (00:00)

Part II: Learning to Survive (15:46)

Part III: Life in a Cabin (19:20)

Part IV: Man vs. Beast (33:36)

Part V: Death of a Daughter (44:41)

Part VI: Going Home (49:27)
