Westerns and/or survival adventures set in Alaska, the Yukon Territory, the Pacific Northwest, or elsewhere in the Boreal or Arctic regions. This Western subgenre often features the Gold Rush, Mounties, sled dogs, the timber industry, killer wolves, or historical dramas concerning the First Nations or Inuit peoples of the region.
