Get ready for another collecting adventure for actinolite and rhodonite in the Wrightwood area. This is a local trip suitable for passenger cars. We’ll be searching the washes and canyons in this area. Light hiking is required for this trip. For more details, please email me at firstname.lastname@example.org with the subject “Wrightwood Field Trip.”
Join us Tuesday, June 15 for a journey through the deep Earth, with Dr. Krista Sawchuk. The deep Earth, which encompasses the mantle and core, makes up 99% of our planet. Because we can’t physically go to the deep Earth, scientists employ a variety of techniques to learn more about it. Dr. Sawchuk will share what we do know about the deep Earth and how her research on the behavior of minerals at high pressures and temperatures is helping us learn more about the chemistry of the mantle.
Dr. Sawchuk recently graduated from UCLA with a PhD in geochemistry. Her dissertation research focused on the high-pressure behavior and chemical reactions of volatile-bearing minerals in Earth’s mantle. Since graduating, she started a postdoctoral research
position at Los Alamos National Lab in New Mexico where she continues her high-pressure research. In her spare time she enjoys mineral collecting and curating her personal mineral collection.
The Tuesday, June 15 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!
August 2021 Show Rescheduled for March 2022
Pasadena Lapidary Society’s 62nd Annual Tournament of Gems “Inspiration Unearthed”, which was planned for August 14-15, 2021 in Arcadia, California, has been cancelled. Stay tuned for information regarding our March 2022 show.
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.

Forsaking the desert, we’ll head deep into the forests of the Sierra Nevada Mountains. The PLS May field trip will be to the Obsidian Dome area where we will study the products of volcanic activity near Mammoth Lakes, CA. Geologically speaking, this volcanic activity is thought to have occurred fairly recently in the summer of 1350AD. This is a one day trip.
We will start at Obsidian Dome–a plateau with some small hills on top, littered with various sized pieces of obsidian. Most of the obsidian pieces at the Dome have tiny gas bubbles and aren’t gem quality but the shiny glass pieces almost glow in the morning sun.
We’ll head to Crowley Lake after touring the Dome to look for fist size chunks of obsidian and arrowheads in the hills overlooking the reservoir.
After that, we’ll stop at Hot Creek visitor center, visit the free hot tubs in the area and hopefully explore some mine tailings looking for minerals related to gold mining.
High clearance is recommended for this trip.
For more information, please contact Rex at email@example.com. Please put “Obsidian Dome field trip” in your subject line.
We’ll be rock hunting near Sperry Wash in Tecopa, CA on Friday and Saturday, April 16 and 17. We’ll camp out on Thursday and Friday nights. Saturday night camping is optional . A high clearance (SUV or pickup truck) is required for this trip.
There will be plenty of variety on this trip, as we’re searching for amethyst, precious opal, fossils, and palm root agate. Please RSVP to Rex at firstname.lastname@example.org for updates and additional information.
Obsidian is a popular lapidary material to collect and cut. Join Pasadena Lapidary Society at the April general meeting, as lapidary artist Terry Wilson takes us on a virtual trip to Davis Creek and other obsidian collecting locations, updating us on collecting site regulations. Terry will share tips on how to inspect the obsidian in the field and back at home. She will also demonstrate how to line up, slab and cab the material to bring out the best of their unique optical properties, including how to cut a cab exhibiting the cat-eye effect.
The April Rock of the Month will be presented by geologist, Dick Weber. Dick will take us on a tour of a hidden treasure: the Petrified Wood museum of Nebraska.
Join us virtually for the April 20 Tuesday night meeting by RSVPing to joenmar1[at]verizon.net for a Zoom meeting link, using ‘PROGRAM MEETING’ in subject line.

Pasadena Lapidary Society’s Tuesday, March 16 program meeting will feature geologists Dick and Mary Pat Weber, whose presentation will focus on the geological wonder of New Zealand. From volcanoes to glaciers, caves and fjords, finding so much variety of terrain in such a small geographical area would be impossible anywhere else on Earth.
The Webers are exploration geologists who spent a month in 2007 visiting every corner of this tiny island nation; they have worked and travelled extensively in North America, Australia and New Zealand.
Our program meeting will also feature the Rock of the Month, by PLS member David Lacey, whose presentations are always informative.
