The Teton–Yellowstone tornado was a rare high-altitude tornado which occurred on July 21, 1987 in the U.S. State of Wyoming.[2] Rated at F4 on the Fujita scale, it was the strongest tornado ever recorded in the state.[1] The tornado cut through a 24-mile (39 km)Template:Convert/track/adj/on long, 1.5-mile (2.4 km)Template:Convert/track/adj/on wide swath of the Teton Wilderness and Yellowstone National Park, and even crossed the Continental Divide.[3] The damage occurred at elevations ranging from 8,500 to 10,000 feet (2,600 to 3,000 m), making it the highest altitude violent tornado recorded in the United States.[2] No human fatalities or injuries were recorded,[1] but up to 1,000,000 trees were uprooted by the storm.[4] Most of the damaged forest later burned in the Yellowstone fires of 1988.[3]
