Sikhote-Alin Nickel-Iron Meteorite fell in the Maritime Territory, U.S.S.R., on February 12, 1947. Hundreds of witnesses watched a shower of fireballs crash land in the thick Sikhote-Alin Mountain forest. This was the largest witnessed single meteorite fall. It produced 106 impacted holes and rained 23 tons of meteorite fragments. This meteorite displays regmaglypts, thumbprint-like depressions, and has ragged twisted and distorted surfaces. This occurred because the meteorite broke up at low altitude and was not subjected to the intense ablation that would have smoothed its surface. The meteorite is classified as type (IIAB) in Catalogue of Meteorites, fifth edition (2000), pages 462 & 463.
