Description: Erythrite on Talc Hunting Hill Quarry, Rockville, Montgomery Co., Maryland, USA 7.4 cm. x 5.2 cm. x 2.4 cm. I'm not aware of erythrite ever having been officially reported from this now off-limits locality, which has produced more different species than any other locality in the state. Joe Dague obtained the specimen from Jay Lininger, who purchased it from Fred Schaefermyer, who collected it sometime in the late 1980's It is now in my personal Maryland collection.
