[Rockhounds] Cactus Calcite

[Lanny R]

Hi Larry,

Scott Werschky (Miner's Lunchbox; Reno, NV) had a bunch of specimens  
that looked like those at the Denver Show in 2002. They were labeled  
as aragonite from the Northern Lights Mine, Yerington District.

That mining district is at the western edge of Yerington. There are a  
lot of mines there with large dumps; the mines are known for a long  
list of secondary minerals, and some sulfides; and some zeolites in  
the area.

Regards,

Lanny
