On February 15, 1948, a massive fireball was widely witnessed across the mid-western US. A shower of stones fell across a large area, centered around Norton County Kansas. The largest stone was a whopping 1.1 metric tons and it still remains the world's largest aubrite. The meteorite was strange in appearance, with a brownish irregular crust and a largely-white matrix. Analysis revealed it to be an achondrite of the aubrite type. Norton County is a classic American fall of a rare type of meteorite. Every collector should own an example of this meteorite.
