Alaskan Thunder Fuck AAA also referred to as ATF. Matanuska Thunder Fuck or Matanuska Tundra is a legendary sativa strain of marijuana originating from the Matanuska Valley region of Alaska. According to legend, it was originally a northern California sativa crossed with a Russian ruderalis. But sometime in the late 1970s, it was crossed with Afghani genetics to make it more vigorous. Alaskan Thunder Fuck typically features large. beautifully frosted buds with incredibly strong aromas of pine, lemon, menthol, and skunk. Known for having a relaxing yet intensely euphoric high, it is also described as having a “creeper” effect as well as a significant increase in appetite.
