Nice cut specimen of this important fall associated with establishing recovery methods. I took this photo at the Smithsonian.
From that unimpeachable source, Wikipedia:
On January 3, 1970, four stations (Hominy OK, Woodward OK, Pleasanton KS, and Garden City KS) of the Prairie Meteorite Network simultaneously photographed the track of a meteoroid fireball. Analysis of the photographs indicated that a meteorite might have landed within an area east of Lost City. This was the first time in the US that simultaneous photography of a fireball from multiple observation points was achieved, making it possible to calculate a trajectory and delimit a search area on the ground.
Six days later, Gunther Schwartz, field manager, went to the Lost City school to ask questions to see if anyone had seen or heard anything about it, at that time a maintenance man and bus driver by the name of Isaac Gifford told the scientist he had seen it while he was raccoon hunting. Gifford took Schwartz to the spot where he had seen the meteorite in the air close to where he was hunting, they walked to the location and soon discovered the meteorite. "Suddenly there was the black rock in the road, and I wondered what it was doing there, and got out to look at it," Schwartz said. "And then you get hysterical. Just think of the odds against finding it there. Fantastic."
Three additional smaller meteorite fragments were recovered later: on January 17, a fragment weighing 272 grams; on February 2, one weighing 6.6 kilograms; and on May 4, one weighing 640 grams within one-half mile of Lost City. |

there is a much better photo of this same specimen at the bottom of the Met Bulletin summary for Lost City. For a Fall recovered in a month this one has a strange "weathered" look. I guess other high metal H falls have developed this look... like Zag maybe, etc. |
