Alaskan Thunder Fuck (also referred to as ATF, Matanuska Thunder Fuck or Matanuska Tundra) is a legendary sativa-dominant strain originating in the Matanuska Valley area of Alaska. According to the legend, it was originally a Northern California sativa crossed with a Russian ruderalis, but sometime in the late 70s it was crossed with Afghani genetics to make it heartier. ATF usually presents large, beautifully frosted buds with incredibly strong odors of pine, lemon, menthol, and skunk.
