An easy favorite among meteorite enthusiasts, the Sikhote-Alin meteorite fell in eastern Siberia on February 12, 1947. It was the largest meteorite event in recorded history. The fall, which generated an enormous fireball, was observed by many eyewitnesses and a series of expeditions was sent to the site by the USSR Academy of Sciences between 1947 and 1970. The fall site, known technically as a “strewnfield,” was studied in detail and Russian scientists excavated 180 of 200 identified impact features. Naturally sculpted pieces, such as this 2,889-gram example, present beautiful surface formations and comprise only about 20% of all recovered masses, as the majority shattered into smaller, shard-like fragments. In recent years, amateur and professional meteorite hunters scoured the strewnfield using metal detectors, while braving ticks, snakes, Siberian tigers (and, some claim, the Russian mob). No new meteorites from this — the world’s largest crater field — are being found today and streamlined natural space sculptures such as this superb example are highly sought after by collectors.
