PLS Booth at Barnhart School Carnival in Arcadia – Saturday, October 22, 11 a.m. – 4 p.m.

Bring the kids to the Barnhart School Carnival this Saturday, have some fun with the carnival games, enjoy food and drinks, check out the vendors, and stop by the Pasadena Lapidary Society booth while you’re at it.

We’ll be featuring do-it-yourself ‘My Rock Collection’ kits. Youngsters (and adults as well) can choose from an assortment of mineral specimens that we’ll have on hand and compile their own kits. This makes a fun first step toward a future interest in rock collecting as a hobby and/or Earth Sciences as a vocation. These rock collection kits were a huge hit at our August gem and mineral show this year.

The Carnival will take place on the Barnhart School property at 240 West Colorado Boulevard in Arcadia. CA 91007. barnhartschool.org

PLS August 16th Meeting takes a look at ‘Geology from 30,000 feet above’

The August general meeting will feature a talk by member Paolo Sanchez who will focus on large-scale landscape geology. The presentation should be helpful for understanding Earth science, and to an extent, minerals, from the viewpoint of the window seat of a plane. While flying across the state and the country, Paolo took many pictures of geologic landscapes. He plans to talk about prominent geologic features such as the San Andreas Fault, Cascade Volcanoes, and the Colorado Plateau. We hope to see you there!

This program meeting is at 7:00 p.m. at Fellowship Hall of The Santa Anita Church, 226 W. Colorado Blvd., Arcadia, CA 91007. Come to learn and make new friends; open to the public, free admission.

DIY ‘Field Trip’ to… Quartzsite, AZ!

For the month of January, many members of Pasadena Lapidary Society join the ranks of rockhounds and lapidarists across the nation – and beyond – in an annual sojourn to our ‘mecca’ of rocks – Quartzsite, Arizona. While this isn’t a fieldtrip that requires a rock hammer, shovel or other tools, it’s a great opportunity to see what wonderful gems and minerals exist in our world – all in one place. There are several gem and mineral shows which are held between December and late February in this town, which swells to over a million visitors in the month of January from a paltry 3,714 +/- residents the rest of the year. One of our favorite shows to check out is the QIA Pow Wow, which takes place this year from January 19 – 23, 2022, with free admission and free parking and way more than a day’s worth of treasures to see. It’s like a giant open air swap meet held under the beautiful blue sky with giant puffy white clouds floating overhead – which sometimes open up with a quick light rain or a heavy shower – then dissipates as quickly as it starts. Quartzsite is just 18 miles east of the California border, along Interstate 10. One can make it a full day trip, or if you’re able to secure lodging in Quartzsite or Blythe, CA, turn your visit into more than one day so you can visit the other shows taking place as well, such as Tyson Wells or Desert Gardens. If you prefer to take an RV and camp, there’s plenty of open space just on the outskirts of town. How to get there? Take I-10 East until you get to Quartzsite, about a four hour drive from Pasadena when traffic isn’t bad. We often make a quick stop at Chiriaco Summit either on the way to or from AZ, where one can fuel up and stop for a bite or snacks.

Tuesday, Nov. 16 Virtual Program Meeting Explores the Chixculub Impact Event with Paolo Sanchez; 7:00 p.m.

Pasadena Lapidary Society’s very own future geologist/geophysicist, Paolo Sanchez, will present “Traces of Extinction: The Search for Rocks and Minerals at Chixculub” for our November program meeting. For those wondering what the heck ‘Chixculub Impact Event’ is, think meteor meets dinosaurs. Paolo will present his current ongoing research examining tektites derived from Chixculub and what their respective chemistries tell us about the minerals and lithologies associated with the impact event, with the potential of understanding the lithology of the meteor itself.

Earlier this year, Paolo was awarded the California Federation of Mineralogical Societies’ (CFMS) Robert O. Deidrich Memorial Fund Scholarship for school year 2020-21. He’s been studying geosciences at UC Berkeley, working his way up to a PhD and possibly obtaining a career as a professional researcher.

There will be no Rock of the Month discussion for this meeting.

The Tuesday, Nov. 16 program meeting starts at 7:00 p.m. via Zoom. To join us, send an email to (new email address!)… marcia.pls.emails[at]gmail.com in advance, using ‘PROGRAM MEETING’ in subject line, and request the Zoom meeting link. We’re looking forward to seeing Paolo – and hope to see you virtually as well!

Tuesday, Oct. 19 Virtual Program Meeting Focuses on Urban Rockhounding in Tucson; 7:00 p.m.

Among some of our favorite rockhound travel guides are Dick and Mary Pat Weber. For the Tuesday, October 19 presentation, Mary Pat will take us on a Practical Guide to Urban Rockhounding in Tucson.

In a few months dealers, buyers, and collectors will gather together for the largest rockhound  event in the world.  You will find great bargains relating to all aspects of our hobby offered by vendors from all corners of the globe.  If you can’t find it in Tucson, it probably doesn’t exist anywhere.  According to Mary Pat, you will run out of money long before you cross off all the items on your wish list.

With over forty shows from which to choose, it can be a bit confusing for the first-timer.  Mary Pat will offer practical advice for navigating though the “Tucson experience” to make it both efficient and fun.  This program is jammed packed with photo highlights of the biggest club show in the world, including specimens from world class museums such as the Smithsonian and other private collections. If you’ve been thinking about visiting Tucson for the rockhound shows but have yet to, here’s a chance to see what they’re all about.

PLS member Mona Ross will provide October’s Rock of the Month talk on one of the world’s rarest gemstones, Grandidierite.

The Tuesday, Oct. 19 program meeting starts at 7:00 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. Hope to “see” you there!

Lavic Siding February 13th, 2021

Miles from Pasadena, about a third of the way between Barstow and Needles, is the sleepy town of Ludlow, CA.  Most of the time, people never even notice it’s there, unaware that a well known jasper collecting area beckons in the blistering desert heat.  Such is Ludlow most of the year. 

Ludlow in the dead of winter is totally different. The ground is stripped of vegetation, blown away as tumbleweeds, or consumed by moisture-loving denizens of shifting desert sands.  The barren landscape causes the jasper to magically appear on the desert floor waiting for us to pick it up.  February’s trip will be on Saturday the 13th, to the renowned Lavic Railroad Siding jasper location near Ludlow, CA.  Our meetup spot is 148 miles from Pasadena.  We’ll meet there at 9 AM. Late arrivals will miss the fieldtrip. Read on for further information.

All colors, shapes, sizes of jaspers and agates cover the ground at Lavic Siding.

Since this is a semi-local trip, it will be for one day only.  We’ll explore the traditional Lavic Jasper collecting areas and the brindle jasper location in the foothills north of Ludlow.  

Red, ochre, brown, black… jaspers, agates… one in back has some drusy.. all found in the vicinity of Lavic Siding.

A high clearance vehicle is required for this trip, but 4wd is always better. Attendees will need to sign a waiver of liability.   RSVP is required.  Please email rexch8[at]yahoo.com for directions, inserting LAVIC FIELDTRIP in the subject field of your email.
