Alaskan Thunder Flower (also referred to as ATF, Alaska Thunder F**k, Matanuska Thunder F**k, or Matanuska Tundra) is a legendary sativa-dominant strain originating in the Matanuska Valley area of Alaska. Its lineage as a landrace strain is (Northern California Sativa x Russian Ruderalis) x Afghani Landrace.
 
According to the legend, it was originally a Northern California sativa crossed with a Russian ruderalis, but sometime in the late 70’s 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. Known for processing a relaxing yet intensely euphoric high, it is also described as having a “creeper” effect as well as pronounced appetite enhancement.
