A Geologic Tour of Australia, via Zoom, is featured presentation for Tues., May 18 Program Meeting; 6:30 p.m.

Join us for our May 18 Program Meeting as we explore Australia’s most iconic natural wonders and visit several geologic sites that are unfamiliar to most people. Our guests, Dick & Mary Pat Weber, are retired exploration geologists and will take us on the armchair trip. In 2007 and 2008 they spent a year on what they refer to as their “Rocks ‘n Crocs” tour of Australia looking at and photographing the natural features and geology of the largest country in Oceania.

For our May Rock of the Month talk, Mary Pat Weber will present an introduction to a lesser known member of the garnet family, the rare and highly prized green garnet, which gives emerald a run for its money.

The Tuesday, May 18 program meeting starts at 6:30 p.m. via Zoom. To join us, send an email to joenmar1[at]verizon.net in advance, using ‘PROGRAM MEETING’ in subject line, and request the Zoom meeting link. We hope to “see” you there!

March 13, 2021 Field Trip to Sidewinder/Ord Mountain

March’s field trip will be a return to the Sidewinder Mountains.  High clearance or short wheelbase vehicles are recommended for this trip. 2wd is okay. Those with passenger vehicles might need to be shuttled when we get close to the collecting sites. We’ll be searching for both tri-color marble (pictured above) and blue marble.  Tri-color marble is a beautiful green, black, and white material and is perfect for yard rock and spheres.  It’s also a good beginner material for making cabochons. We’ll also explore tailings piles in the Ord Mountains for chrysocolla and malachite.  copper minerals

Our last stop will be to the Prime Cut Rock Show in Lucerne Valley.

Focus on Ametrine for Tuesday, February 16th

Join us for our next virtual general meeting on Tuesday, February 16th. We will be joined by our friend, Professor George R. Rossman. Professor Rossman will highlight the troubled history of Ametrine. Specifically, he will discuss the controversy that developed about ametrine early on, and his personal experience traveling to Brazil amethyst mines, the Bolivia ametrine mine, and Russia where synthetic ametrine was produced. RSVP to joenmar1[at]verizon.net for a Zoom meeting link, using ‘AMETRINE’ in subject line.

The Rock of the Month will be presented by PLS member Phil Lahr, who will discuss “Tumbling through the Pandemic” – a personal journey of rock tumbling triumphs and tragedies during the summer of 2020.

North Cadys Fieldtrip; Nov. 27-29, 2020

PLS Members visited one of our favorite spots for gemstones in the North Cady Mountains, about three hours northeast of Pasadena, over Thanksgiving weekend.

The Cady Mountains have produced more gemstones than almost any other Southern California location and we explored the northern part of the range, looking for jasper, agate, fluorite, calcite, and amethyst in places where few rock hounds go. You can join us in the Cadys sometime in the future, by becoming a member of Pasadena Lapidary Society. Check out the photos below to see some of our finds.
