Buck Mine, Cripple Creek District, Teller Co., Colorado, USA
A locality in the Cripple Creek District (purportedly in an old mine shaft) that produced unique epimorphs / "casts" of smoky quartz and chalcedony replacing laumontite. The smoky quartz has a distinctive muted silvery-grey color, with very little luster and a somewhat stalactite-esque growth due to the way the quartz overgrew the pre-existing laumontite. The lack of luster on the Quartz is most likely due to a micro coating of chalcedony.
Specimens were collected in 2010 by Quinton Cross and Ralph Buck. See http://www.mindat.org/photo-241718.html for a similar quartz replacement specimen from Cripple Creek.
