The Del Air Rockhounds Club Welcomes You!!





www.Facebook.com/DelAirRockhounds


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.

RIP Bob Jones:

For those of you who have been long time rockhounds, Bob Jones, a very long time friend of the mineral collecting community, passed away on May 31st. He was in his 90's. Bob's enthusiasm and unstoppable optimism along with his appreciation for mineral collecting and his passion for introducing people to the joy of mineral collecting could not be ignored. He was editor of Rock & Gem Magazine for decades and his many articles where he wrote about collecting localities will never be replicated. Bob was a generous and enthusiastic man who knew no strangers and he will be sorely missed by many.

WE DID IT:                                                                                                                                                                               
The Del Air Education Outreach Program ended its half way mark for 2024 with a BANG!!! Just before the school break we had two events going at the same time. One a school we have not been to before and the huge CFMS/AMFS Show! On a Thursday evening, we had a booth at a school STEAM NIGHT. Members, Shellie Van Winkle, Pam Abbott, Diana Durfee, Bob & Maxine Dearborn, Jon Meredith, Steven & Coriolis Koch were setting up, running and taking down the booth for a few hours. Our first time at this school and they were happy to talk to us about rocks. On this same Thursday, Jeff Dengrove and Bob Knox were at the Ventura Fairgrounds, setting up our club display case and educational booth. They did this for hours too! Now the CFMS/AFMS Show was a BIG weekend for our club. Besides the setting up and taking down our display case and educational booth, we had many members attend the show to run our booth. Members Jeff Dengrove, Bob Knox, Pam Abbott, Maxine & Bob Dearborn, Diana Durfee, Jon Meredith, Michael Lawshe, Keri Dearborn, Dan Farber were all there on and off for the Fri., Sat., Sun show and spent many hours at our booth talking to lots of people interested in our booth and rocks and minerals. Also two of our members were special speakers for the show. Keri Dearborn - Geology of the Coastal Islands and Maxine Dearborn - Amber. Both of their talks had a well attended audience. We also had a member, Emmy Silverman, who had a dealer booth at this show. You can see our club was very busy at the end of this booth/talk season and many members were involved with these events. We hope you all can take a break now - take a vacation somewhere - and rest up for the second part of the year coming up!

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.
