Pyrite - Buick Mine, USA
Mineral: Pyrite
Locality: Buick Mine, Bixby, Viburnum Trend District, Iron County, Missouri, USA
Description: I love this. The "Pyrite bars" from Buick are actually stalactitic. If I am not mistaken, they are from a one-time find in 1974 called the "Butterstick Pocket" at the 1250 level of the mine. 100 specimens were found in the pocket.
