Alaskan Thunder Fuck (also known as ATF, Matanuska Thunder Fuck, or Matanuska Tundra) is a legendary sativa-dominant hybrid strain with roots tracing back to the Matanuska Valley in Alaska during the 1970s. Its lineage is a mix of landrace genetics designed to thrive in cold climates, typically described as a cross between a Northern California sativa and a Russian ruderalis, which was later crossed with Afghani indica genetics to improve hardiness, resin production, and potency.
