The Del Air Rockhounds Club was founded in 1954 with members mostly residing in the San Fernando Valley area of California. Our club is a non-profit organization dedicated to sharing knowledge of the lapidary arts and techniques, geology, mineralogy and related fields. We own our own lapidary equipment with members available to teach and demonstrate lapidary techniques to other members. Our members enjoy lapidary related programs, demonstrations, exhibitions, displays and lectures. We also take monthly field trips to our local deserts & mountains for exploration and the study and collection of lapidary and mineral specimens.

Have you ever wondered about the MOHS hardness scale? Here are some facts about it!
  • The MOHS scale is a system used to identify the hardness of rocks and minerals.
  • There are many things that people use to help describe or discover a rock’s identification, but the MOHS scale is a good, efficient one to identify types of minerals.
  • The MOHS process suggests scratching two minerals together in order to find the hardness of the two minerals.
  • Who? The person who invented the MOHS scale was Friedrich E. Mohs.
  • When? The MOHS scale was created in the year 1812. How? Observing the mineral’s surface when it is scratched by a substance of known or defined hardness.
  • When? The scale was found in the early 1800's in one of Friedrich’s books.
  • What? The MOHS hardness scale means Scale of Mineral Hardness.

Del Air Club Annual Wrightwood Field Trip Report:
Thanks to member Shellie Van Winkle, we met again at her house in Wrightwood, CA for our annual field trip. There were breakfast snack items on the table when we all got there and fresh coffee. Boy, what a way to start collecting rock! Our members trooped off, about 2 city blocks, to the collecting area and had a great time filling their bags. Some had large rocks too big for their bags. After about 2 hours of collecting, we all headed back to the house for a huge pot-luck lunch of warm food, salads, finger food and rich desserts. Every field trip should be like this one! Members present were: Shellie Van Winkle, Bernadette Friedman, Jeff Dengrove, Dan & Diana Durfee, Aileen Beckers, Michael Tschacher, Louise Ratliff, Bob & Maxine Dearborn and Peggy Donner. Again, Thank You Shellie for a great, easy and fun way to have a field trip.

May's General Meeting Program: 'Southern California Tourmalines'                                                Presented by Walt Lombardo

Come join us at our May general meeting where Walt Lombardo will be discussing Southern California Tourmalines. Walt is a geologist with over 35 years experience related to mining and mineral exploration. For 16 years, he managed the Las Vegas Office for the Nevada Division of Minerals. He has also worked for Desert Research Institute (part of the University of Nevada system) and served as a consultant for several mining and exploration companies.  Walt has lectured nationwide on topics relating to geology, mineralogy, gemology, mineral resources and mining fraud. 

Nevada Mineral & Book Company (NMBC) was established in 1985, when Walt started selling mineral specimens and out-of-print publications at gem & mineral shows and through mail order. In 1989 he acquired the inventory of the Mineralogical Record Book Department, and incorporated in-print books and journals into his offerings. Over the past 30 years, we have evolved to offer the researcher, educator and collector a wide variety of publications and specimens in a "one-stop" shopping environment. In 2001 we opened our first retail location in Henderson, Nevada. In August, 2009 we relocated and opened our new store and gallery at 342 S. Tustin St. Orange, CA 92866. They offer a wide variety of new, used and out-of-print publications, as well as mineral and fossil specimens, lapidary and decorator items, and mining stock certificates and other ephemera. They have one of the largest inventories of earth science-related publications in North America, so plan on staying a while if you come to visit his store. You will not be disappointed.

Report on Del Air Shop Day - Sat. April 13:             

On Saturday, April 13th we had our Spring workshop.  Four members attended; Dan Farber, Kyle Morris, Steven and Coriolis Koch. We had a successful day, prior to the rain. We used both grinding and polishing units, the 18 inch and 10 inch saws, the flat lap and the drill press.  We cut and polished a variety of stones. We encourage ALL members to take part in these shop days. Our next shop day will be sometime in July, August or September. Keep an eye on your upcoming monthly bulletins for more details.

Club Display Case @ AFMS/CFMS/VGMS Annual Show in May: 

The Del Air club will be installing a display case at the annual show and convention at the Ventura Fairgrounds May 24th thru the 26th. It will be a non competitive entry showcasing our club and the lapidary items we have created at our various shop days, wire wrapping and chain-mail classes, etc. We are asking all members to loan a lapidary item or two that you created, cut, polished or assembled while a member of the club to the board for possible inclusion in the case. We are looking for 12 to 14 items for inclusion in the case depending on size. It could be a polished specimen, a jewelry item or any type of rock related handicraft.  Please bring your loan items to our May 2024 meeting labeled with a brief explanation of the item and your name & phone number. All items will be returned to members at our June meeting. This is great exposure for our club to AFMS/CFMS members from around our state and the entire country.

Agatized Coral - Tampa Bay, Florida:


The photos above are of the world famous Tampa Bay Agatized Coral. They are from an ancient coral bed that encompassed much of the state of Florida approximately 38 to 40 million years ago when Florida was underwater. I acquired this specimen at a rock sale held by my Florida rock club, The Withlacoochee Rockhounds of Hernando, Florida. It measures 7 inches from left to right and 2 ¾ inches from top to bottom. Specimens of this size and quality go for upwards of $85 or more on eBay but I was able to snatch up this beauty for only $20. A steal of a bargain, for sure!

'Generalized Mineral Identification'                                                                                                        Presented by Bob Dearborn & Bob Knox

Our club recently participated in a "rock swap" with a club from Riverton, Wyoming. A "rock swap" basically means we sent a box of California rocks to them and they sent a box of Wyoming rocks to us. This month, at our general meeting, the two Bobs will show us how to identify these rocks utilizing some of the basic mineral identification techniques available today. If any of the membership would like to own any of these Wyoming specimens then make sure you attend our May meeting where these specimens will be available via a special silent auction.

MEMBERS QUARTERLY CHAIN MAIL NECKLACE PROJECT REPORT

As you all know, our club is trying to schedule a quarterly project for our members to participate in. Something to learn about or make or think about. This quarter, Maxine Dearborn led a class on making CHAIN MAIL JEWELRY. She had everything set up with instructions and as the jump ring necklaces were starting to be put together we began to hear “DARN” these rings are really small or OOOPS I just put that ring in the wrong place or BOY this is a challenge! But, parts of the necklace did get done and a couple finished necklaces went home. Others took their incomplete project home to finish. Everyone agreed it was a challenge but fun. I don't think anyone would want to make a full suit of chain mail armor because it would take years! We hope to see more club members on our next quarterly project.

*****************************************************

***June 2024 General Meeting Teaser***

Our June meeting topic will be "What's Your Other Hobby". We ask all members to participate by bringing in and sharing with the group something that you collect or are passionate about outside the realm of rocks or lapidary. This is a great way for all of us to learn something more about each other. So think about what it is you'd like to share and bring it to our general meeting in June.

I am happy to report that Dick Weber is much better and back to his usual self so please come join us at our March 2024 meeting where Dick & Mary Pat Weber have been rescheduled, and will present to us, a tantalizing look at some of the lesser known but still spectacular, geological and paleontological features throughout Australia. Everyone knows about the Great Barrier Reef and Ayers Rock but there are so many more features that are equally impressive but known to only a select few. Hope to see you all there.

Field Trip Report - Del Air CLUB's ANNUAL FOSSIL WHALE BONE TRIP 

On January 27th our club gathered together at Refugio Beach State Park in Santa Barbara, under the guidance of president & field trip chairman, Jeff Dengrove. It was a great, sunny day for the 11 of us and 3 guests who went looking for this special rock. The high tides of the last few weeks undercut the banks and delivered a lot more rock to the area. Members who braved the tide while we were there found fossil whale bones and more interesting rocks that will be displayed at our club meetings. The local islands looked like you could hit them with one of the rocks you didn’t want to keep. We had a great day, took      in a lot of fresh air and brought home a couple neat rocks too!

*********************************************

AN EDUCATION OUTREACH STEM NIGHT AT STANLEY MOSK SCHOOL

 Our education group had another fun evening talking to students and their parents at Stanley Mosk Elementary school's STEM NIGHT event. This was a new school for us and, BOY, were we busy with happy faces. We had our volcano display to talk about and with such a crowd most of the time we had two free games going. Our spin-a-wheel never stopped going and even broke the clicker, which had to be replaced mid-evening. We had lots of rock questions and some even brought their own rocks to be identified. Fun, fun, fun. Members attending for this 3 hour event were: Shellie Van Winkle, Bernadette Friedman, Pam Abbott, Bob Knox and Bob & Maxine Dearborn.

February 2024 General Meeting

Pipe Stone; Presented by Bob Dearborn

Geologically, pipestone is a claystone (argillite). Its scientific name is catlinite (named after George Catlin). The red color results from oxidation of trace amounts of iron (hematite). The pipestone formation began over 1.5 billion years ago when a braided river covered what is now southwest Minnesota. The pipestone quarries have been visited for centuries by American Indians to acquire the red pipestone used to craft pipebowls for their sacred ceremonial pipes. This month, Bob Dearborn will show us this wondrous stone and explain how American Indians accomplished this arduous task.

***********************************************

A Special Silent Auction

The Del Air Rockhounds Club was fortunate enough to have recently acquired a collection of high end crystal and mineral specimens generously donated to the club by a very nice lady named Taryn from Rancho Cascades, CA. The Board has made the decision to offer these specimens for sale to the membership at a special silent auction at our February meeting. There will be 15 or so very beautiful and unique specimens up for auction. There will only be one auction this time and all items will have a pre-assigned starting bid. So bring your checkbooks and be ready to add that special high end specimen to your own collection.
