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.
Our last stop will be to the Prime Cut Rock Show in Lucerne Valley.
Please email Rex at firstname.lastname@example.org for updates and additional information.
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.
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.
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.
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.
Pasadena Lapidary Society member Sue Pang shared some pics she’d taken during her visit in January to the annual QIA PowWow in Quartzsite, AZ. Members who didn’t make it out there this year were certainly there in spirit, as we’re not just lapidarists; we’re ROCKHOUNDS. For those who don’t know, the QIA PowWow is a rockhound’s mega candy store.
Pasadena Lapidary Society (PLS) is proud to announce that member Paolo Sanchez of Burbank has been awarded the California Federation of Mineralogical Societies’ (CFMS) Robert O. Deidrich Memorial Fund Scholarship for school year 2020-21. This award was established some fifty years ago by the late Melba Deidrich in memory of her husband Robert. The recipient of the $2,000 award must be an Earth Sciences major entering his/her junior or senior year at either UC Berkeley or Stanford University. Pasadena Lapidary Society is one of many member clubs in the CFMS.
As Filipino-Americans, Paolo’s parents Debbie and Ferdie trained and worked hard to establish themselves in the U.S.’s medical industry, and through their dedication and experience—as well as wonderful support from his older brother Joshua and younger sister Danielle—Paolo has been able to obtain a first-generation, U.S.-college education at UC Berkeley. With this he plans to continue his passion in the geosciences, working his way up to a PhD and possibly obtaining a career as a professional researcher. He is in his third year of double majoring in geology and geophysics and is developing a research project involving the chemistry of molten glasses (tektites) formed during the meteor impact that killed the dinosaurs (a.k.a. the K-Pg Impact) 66 million years ago.
Paolo became interested in Earth Sciences as a kindergartener, developing an affinity for rockhounding through the years by reading geology field books and old textbooks, then applying that knowledge in the domain. He joined PLS as a Junior member at the age of 12 and since then he has given lectures about geology at PLS’ monthly program meetings, led educational rock and mineral identification seminars, and authored/coauthored numerous geological and mineralogical articles in the monthly PLS newsletter Rockhound Ramblings, among numerous invaluable contributions he has made to the Club. As part of Pasadena Lapidary Society’s community outreach, Paolo has taught basic geoscience to local elementary school students, along with providing hands-on teaching techniques with self-collected rock and mineral specimens.
Prior to UC Berkeley, Paolo interned at Cal State Northridge for a year, doing research for the Geological Sciences Department. At present he is a Research Assistant at both the Berkeley Geochronology Center and at the UC Berkeley Earth and Planetary Sciences Dept. Paolo is also an editor and contributor to the popular non-commercial online mineralogical database mindat.org.
Along with his family, Pasadena Lapidary Society shares great pride in Paolo’s accomplishments, congratulates him at winning this prestigious award, and wishes him much success in his future endeavors.
The California Federation of Mineralogical Societies represents over 100 gem and rockhound clubs statewide, as well as a few clubs in Nevada and Arizona. Visit cfmsinc.org for further information.
Members of Pasadena Lapidary Society, along with most serious rockhounds, wait anxiously all year to make the 3-1/2 hour trek to Quartzsite, AZ in January. Some stay right into February, camping nearby in order to go rockhounding at their leisure, and others check in to the few motels in town or travel the 22 miles back/forth to Blythe, CA for lodging.
One of the biggest draws in Quartzsite is the QIA POWWOW, always held the third week in January. This year the POWWOW runs from January 20-24. If you’ve never been, the POWWOW is like a huge swap meet focused on gems, minerals, rocks and everything related. Admission is free and so is parking. Here’s a weblink to check it out: http://www.qiaarizona.org/.
Self-professed as “The Rock Capital of the World”, Quartzsite is a town in La Paz County of +/- 2,000 inhabitants that swells to a couple of million in January and February each year. Situated 125 miles west of Phoenix at the junction of Interstate 10 and U.S. Highway 95, it enjoys a close association with the Colorado River, just 18 miles to the west.
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.
Our March Program Meeting, originally scheduled for Tuesday, March 17, 2020, in the Donald Wright Auditorium of the Pasadena Central Library, has been canceled based on guidance from the Pasadena Library administration in consideration of the Coronavirus. Information will be posted here in the weeks to come regarding the April Program meeting. Stay safe out there.
Rhodochrosite is so popular with members of Pasadena Lapidary Society that we’re bringing back a two-part video featuring the mining and geology of this lovely mineral. Part One will be presented at the Tuesday, February 18th program meeting. Rhodochrosite is a manganese carbonate mineral that ranges in color from light pink to bright red.
The February Rock of the Month Talk speaker is PLS member Karl Stull. Karl will share some tips and ideas for organizing a co-op display case for Pasadena Lapidary Society’s Annual Gem Show, coming in April.
