A fireball brighter than the sun streaked across northern California and Nevada, trailing smoke and shedding fragments as it decelerated from 64,000 miles per hour. The sonic boom that followed rattled buildings from Sacramento to Reno. When the pieces were found scattered across the hills near Coloma, scientists realized the cosmic intruder had landed in one of the most symbolically loaded landscapes in American history: the same stretch of Gold Country where James Marshall's 1848 discovery at Sutter's Mill launched the California Gold Rush. This time, the treasure falling from the sky was far older than gold.

The meteoroid that became the Sutter's Mill meteorite entered Earth's atmosphere at approximately 28.6 kilometers per second, making it the fastest fireball on record from which meteorites were subsequently recovered. It detonated with the energy of roughly four kilotons of TNT, ...

Analysis classified it as a CM-type carbonaceous chondrite regolith breccia, a type of meteorite that preserves some of the oldest and most primitive material in the solar syst...

Meteor astronomer Peter Jenniskens of the SETI Institute led the recovery effort, piecing together eyewitness reports, photographs, and radar signatures to map the meteorite's trajectory and likely landing zones. The strewn field stretched across the oak-studded foothills around ...

Sutter's Mill, where the California Gold Rush began in January 1848, sits in the heart of the strewn field. The discovery that transformed California and drew hundreds of thousands of fortune seekers west was a chance encoun...
