Fragment from the Lincoln La Paz collection. At about 4 p.m. on February 18, 1948, hundreds of people witnessed a brilliant fireball in the clear afternoon skies above Colorado, Kansas, and Nebraska. Several people heard loud explosions, followed by a roaring sound like the noise of a jet engine. In the smoke train behind the fireball, puffs of smoke appeared where the large meteorite that was streaking across the sky broke apart in smaller pieces. In the following days and months, hundreds of stones were recovered from a large area on the Kansas / Nebraska border, in Furnas County, Nebraska and Norton County, Kansas. The meteorite became known as the Norton County meteorite.
