Tanana, Alaska. It's a village on the very edge of civilization - less than 100 miles from the Arctic Circle. Life here is harsh. The 200 villagers face an ever-changing landscape with everything from fierce weather to wolves at their doorstep. The isolation of living in remote Alaska is real and tangible. Discovery is back in Tanana, Alaska with the season premiere of "YUKON MEN" on Tuesday, September 15 at 9 PM ET/PT. The Yukon Men face new threats to their way of life. The changes can be frightening and cause some people to take extreme measures... and even to reassess their remote lifestyle. Residents find themselves at odds over a trap line, fighting for their livelihood. But they also pull together as a community to battle a pack of wolves closing in on Tanana and to rescue a stranded villager cut off by the sudden breakup of the icy Yukon River. The Yukon Men are constantly reminded of their isolation. Another danger of their remote lifestyle hits home when a medical emergency strikes.
