Lite green Hagstromite with slightly yellow clear plates of Thorneite. Blue balls of Fuetterite and medium green crystals of Timroseite are also present. This was the first specimen presented, designated as P1 which was identified as an unknown but didn't have good enough crystals to do the crystal analysis. My third specimen which was p3 was found to be used for the crystal evaluation. Photo was taken thru a Cannon D60 camera thru a Zeiss Discovery V20 Microscope using Helicon stacking software.

Very lite green crystals of Hagstromite usually found as sprays. Photo was taken thru a Zeiss discovery V20 using a 1.5 Planapo objective with a 10X eyepiece. Helicon Focus was the stacking software used. Found in 2011 and shown later at the pacific micromount society meeting in Redlands. First analyzed by Bob Housley and later given over to Tony Kamp. Specimen is now in the Los Angeles County Natural History Museum. Many thanks to Bob and Tony for this minerals recognition at Otto Mountain.
