VGMS member Terry Wilson will recount a fun CFMS trip to Davis Creek, where the group sampled all of the rainbow obsidian collecting locations currently allowed in this remote corner of California. She will also show you how to slab and cab this special type of obsidian to bring out the best of its optical properties. She will have a table display of rough, slabbed and cabbed material to show you in person what pictures alone cannot do. Terry is Program Chair of the Ventura County Gem & Mineral Society. Her main interest is slabbing and cabbing, and sometimes silversmithing to give her cabs a place to land.


The Rockhound Dennis Miller Show

Dennis will fill us in on January’s birthstone; Garnet. Dennis asks all members to bring in something for Show & Tell each month to share with our members and guests.


Del Air Rockhound’s Annual Whale Bone Field Trip

It’s that time of the year again. Time to get into your cars and travel about 100 miles down the 101 Ventura Freeway to the Refugio Beach exit in Santa Barbara. We’re hunting fossil whale bones, beach agates, the beautiful San Franciscan Shale and many other colorful rocks. Low tide begins just a few minutes after 10 am. Dress in layers and don’t forget to bring yourself a picnic lunch and beverages. There are no stores in the immediate vicinity of the beach. This is a hugely popular trip every year and we regularly enjoy a big turnout. Bring your rock hammer and a sturdy canvas bag or bucket to carry your found treasures. If you’ve never been before, our Field Trip Chair, Jeff Dengrove, will be there with samples of previously found whale bone to show you what to look for. There is a fee to park at California State Beaches, usually $10, but the parking pass can be used at as many State Beaches you wish to visit that same day and there are at least two more within a couple of miles in either direction from Refugio. Save the date! Hope to see you all there.



As you all may know Maxine is very fond of Turquoise, among many other things! In our shopping here and there we see more and more of this White Buffalo Turquoise and thought you might like to know a little more about it. White Buffalo Turquoise is found in only one mine worldwide, the Dry Creek Mine in Nevada. The mine is located on the Shoshone Indian Reservation near Battle Mountain. It was discovered only recently, in 1993. It is said that its name comes from Native Americans in the area, who believe that the stone “is as rare as a white buffalo.” It is believed to form like “normal turquoise,” with the exception of the absence of copper (which makes the turquoise blue), iron (which makes it green), or zinc (which leads to yellow-green turquoise) Because of it rarity, it is also believed that white howlite is sometimes sold as white buffalo turquoise, perhaps by accident by the uniformed, or perhaps intentionally. We know at times we have questioned a piece of “White Buffalo Turquoise” for sale and the seller has said “ Sometimes this is called Howlite“. So be careful out there and look closely at your rocks.                                                    Submitted by: Bob Dearborn

News From the CFMS -    


After speaking with several societies in their area and finding no takers, the Executive Committee reluctantly decided that CFMS needed to hold a no-host show for 2023. As all are aware we were unable to have our traditional show in 3 of the previous 5 years–in 2018 although a club in northern California graciously invited us to hold a Directors Meeting at their show, as a Federation we were not part of their show except for the Endowment Fund table. COVID prevented us from having a show hosted or otherwise in 2020 or 2021. You can plan to be in Lodi June 23-25, 2023. The show committee is hard at work finalizing all the various forms so these can be posted to the CFMS website as soon as possible. The event will be held at the Grape Festival and Harvest Fair in Lodi, CA. This is the same site of a successful no-host show in 2015. First Vice President/President elect Bob Rush will be Show Chairman with Jim Barton acting as his assistant Show Chair. Unlike a hosted show, a no-host show doesn’t have a pool of club members to handle all the tasks involved. We are asking those in the nearby area to let Bob or Jim know how you can help. Volunteers will be needed to help with set up, security, admissions, demonstrations, etc. Most importantly all the clubs will have the opportunity to meet members of the public who could possibly become your future members. Bob plans to put the tables promoting membership at the front of the dealers building so these are the first thing visitors see when they enter the building. Be watching the newsletter for details and information as it evolves. The basic framework for 2023 was begun in 2021 so the committee is basically picking up where it left off when we had to cancel last time due to the uncertainties surrounding the pandemic. Here’s to yet another successful no-host show!


The Art of Being the Meaningful Historian                                                                                                  By: Jennifer Haley, AFMS Historian - Oct 2022 AFMS Newsletter 

As Historians, you have a meaningful job and are a great value to your organization. You are the keepers of all things memorable and significant. You are the storytellers of the past, for today, and the storytellers for the future generations of historians who will be thumbing through your files to celebrate the joys of the earth sciences, and the practice of lapidary arts and crafts. Think of your file boxes as gift boxes given to you, and the gift boxes you are creating to give to the future of our hobby someday. I thought this might be a good time to begin talking to you about the many ways you can take care of your society and federation historian files. Over the many years there have been society, federation and AFMS historians. Lots of boxes and even metal cabinets have been passed from one historian to another over generations of time. This accumulation of so much history can produce a sense of anxiety and a quandary of wondering how to manage not only the space to hold the material, but how to protect it and how to find what you are looking for. Some have asked if it’s even valuable enough to hold onto so much accumulated material. Especially for federations and the AFMS, transporting all the files from a retiring historian to someone new can pose a problem due to the vast traveling distances within their territory. There aren’t any hard-set rules of how to go about this, unless your society or federation states them. You or your society may have piles of file boxes that haven’t been looked at in ages. You might be wondering what condition they are in at this point and thinking, what on earth should be done with them. I am here to offer some good pointers and some creative ideas to help you out. There are so many treasures in those boxes when you are able to find them. Maybe not 100% that you might find personally interesting, but gems in the figurative sense and literally to inspire your members today. As historians, you are usually the backup for storing copies of your organization’s business meeting minutes and reports. You also have the special job of keeping copies of your organization’s newsletters, photos and news clippings of the year’s events and sometimes storing mementos. You are the person members will say at some time or another, “thank you so much for keeping the good memories and for remembering us.” There are different aspects of being a historian. There are various choices available to you about how you can take care of your files, along with ideas to make finding things in the future easier for you . Some organizations are digitizing their files, but if that’s not your cup of tea right now, that’s alright too. Stick with me over the next few months, and in between other historian articles for the AFMS, we’ll go through those boxes together.

The Geological Wonders of California’s Channel Islands

From volcanic sea caves to out-of-this-world sedimentary formations, the Channel Islands are a collection of geologically varied islands. Keri Dearborn will take us on a tour of the Channel Islands to see some of their unique geology, including San Nicolas Island which is a U.S. Navy Base and closed to the public.

The geology of the Channel Islands directly affects the plant and animal species that live there. This is called biogeology. We’ll look at the role geology has played in shaping the living species on the islands in the past and how it continues to do so today. We’ll look for fossils, archaeological sites, and evidence of islands on the move.  

Join Keri for an evening discovering the geologic wonders of the Channel Islands.

Emmy Silverman - Program Chair

Report on our Malibou Lake Event - Saturday, October 1, 2022

Yes, there is a Malibou Lake in the Santa Monica Mountains. And, it has been there for 100 years! Who knew? I didn’t but our club was invited to their centennial festival through the efforts of our member, Jon Meredith. Our booth consisted of two 10 x 10 canopies from 10 am to 6 pm and we talked to a constant flow of people. They were all interested in the free educational game, touch and feel area, spin-a-wheel with its goodies and many kinds of rock materials available for purchase as well as providing general information on the local rocks and fossils. Our members, Chris Ward and Maxine Dearborn gave a one hour PowerPoint talk on the history and geology of the Santa Monica Mountains and they had a very large audience. They also had a lot of questions about the subject because a lot of the people were from the surrounding local areas. Our club had a great time at this festival. It was a long day but we had a lot of help and the weather was just right. Members attending: Chris Ward, Bob Knox, Shellie Van Winkle, Bernadette Friedman, LaVere & Christine Schmidt, Jon Meredith, Jeff & Emmy Silverman and Bob & Maxine Dearborn.         Bob Dearborn-Education Outreach
