Chico (Colfax County, New Mexico, USA) L6 impact breccia (stone) Found January 1954

Chico is one of the largest aerolites yet found... a huge 231 pounds! This meteorite is also notable for some extraordinarily large sized chondrules in the matrix - the largest being an ellipsoid measuring 57x44x26mm and weighing an astounding 120g!

The Chico chondrite almost escaped formal recognition and risked being discarded as terrestrial slag, because the first small sample submitted for analysis was just a piece of the rough caliche coating that concealed the inner meteorite. However, the whole mass was later transported to the Institute of Meteoritics and cut sections revealed a meteorite of great interest.
