This meteorite originates from the largest meteorite shower of the last several thousand years. Its journey began 320 million years ago, when a giant iron mass broke-off from its parent body in the asteroid belt and wandered through interplanetary space until it encountered Earth on 12 February 1947. Upon slamming into the atmosphere it began to break apart, producing a fireball brighter than the Sun as it sailed over Siberia’s Sikhote-Alin Mountains. The shockwaves from the low altitude explosion of the main mass collapsed chimneys, shattered windows and uprooted trees. Sonic booms were heard more than 300 km. away and a smoke trail 33 km. long persisted in the sky for several hours. Many of the resulting meteorites produced impact craters as large as 26 meters—with nearly 200 craters having been catalogued. A famous painting of the event by artist and eye-witness P. I. Medvedev was reproduced as a postage stamp issued by the Soviet government in 1957 to commemorate what many likened to what was seemingly the end of the world. There are two types of Sikhote-Alin meteorites: the gently scalloped specimens (that broke free of the main mass in the upper atmosphere (see lots 20 & 52) and the jagged and twisted specimens (that resulted from the low-altitude explosion of the main mass).
