Yes, the General Meetings at our normal PCC meeting location have been cancelled. BUT! There will be an internet meeting via ZOOM. Our President, George Rossman is offering an MSSC meeting via ZOOM as follows: He uses Caltech’s ZOOM license which allows meetings to last as long as the need [Caltech has given him permission to do this].

Join us: Friday, August 14, 2020 at 7:30.

Pseudomorphs, Trickster Mineral Specimens, presented by Howard Heitner

He was the president of the Stamford Mineralogical Society for many years and has been collecting minerals for sixty years. He started as a field collector, collecting in New York, New Jersey, Maine and other states.


Members who want to do this must respond to our Programs chair, Rudy Lopez at no later than Tuesday August 11, 2020. Please include “August ZOOM Meeting” in the subject line of your response. This response date will allow time for us to send you the information needed to participate in the ZOOM meeting and will also allow time to get everything organized at Caltech. If enough people respond positively (minimum: 10 positives), we will go ahead with a ZOOM talk. If only a small number are interested, then, it is probably not worth the effort.
