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!
PLS will be rocking in the Cady Mountains at the end of the month. This 3 day trip will begin Friday at noon on November 26 and finish on Sunday, November 28 at 11 AM. We’ll be searching for agates, jaspers, and fluorite. Though you can make it to base camp with high clearance 2wd, 4wd is required for the rockhounding part of this trip.
Must RSVP to field trip leader, Rex, at firstname.lastname@example.org with the subject line “Cady Mountain field trip.”
Whether it’s planting a new tree for the garden or extracting a boulder while mining, there’s something satisfying about digging and rocks. No, I’m not talking about hard rock mining, for that is pure torture. I’m talking about the Sierra Pelona claim out in North Edwards, CA, a renowned location for prize winning travertine onyx. The only difference is that while rocks are the bane of any happy garden, the goal at the Sierra Pelona is using a pry bar to make that rock wiggle and finally extracting it in triumph.
Though hundreds of clubs and rockhounds have visited the claim over the years, this location still produces hundreds of pounds of quality travertine onyx.
On our last visit October 30th, we were able to excavate one hundred pounds of travertine in about 2 hours. That’s a pretty good haul for any rockhound and the colors were spectacular. I hadn’t seen the greens that color in a few years, but it looks like the seam is into a green band right now. Greens, reds, and even blue bands of agate make beautiful spheres or cabochons.
The claim is open to rockhounds everywhere and though access is fairly straightforward, you’ll need a high clearance vehicle. This is a great trip for an experienced miner or just a weekend warrior who wants to get out and smell the dirt.
The weather is cool and it’s time to get out your picks and shovels and go rockhounding. No one knows when the green banding will run out again, so plan your next trip with your local rockclub to collect this beautiful material.
Our October field trip will be to Brown/Castle Butte, the Sierra Pelona travertine claim, and the Rio Tinto/U.S. Borax visitor center in Boron. This area is known for a variety of minerals, and we hope to find agate, bloodstone, travertine onyx, ulexite (“TV rock”), kernite, and petrified wood.
High clearance truck or SUV is recommended. For more info, please contact email@example.com with the subject line “North Edwards field trip”.
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!
