October Board Meeting by Linda Nelson, Secretary

President’s Message

Dear Members, We all had a great time at our silent auction and sale at the October workshop. Lots of good food helped to keep our

strength up for bidding and buying. Thank you to all who nominated and voted for our 2015 Rockhound of the Year! We’ll announce the names at the November program meeting.

Thanksgiving will soon be here and we can all give thanks for family and friends. For many of us our rock friends are our family also. They are the gems in our lives. Opps, can’t forget pets! The Thanksgiving field trip usually has great weather and the field trip is a great way to enjoy the outdoors. Since the trip is with the CFMS there should be people from other clubs to get acquainted with and share rock stories – some of the stories may even be true!

Our Annual Meeting and Christmas party is going to be on Thursday, December 11th, this year since Tuesday didn’t work out. We will have the potluck and raffle baskets. In lieu of crafts at the meeting we’ll have a special project for the December workshop. Details will be in the December bulletin. See you at the next meeting

…….. Marcia Marcia Goetz, President

WORKSHOP This Month’s Workshop Program:

Chain and Bead Bracelet

Ed Imlay will demonstrate how to take any ordi-nary jewelry chain and turn it into something that will turn heads! The bracelet is made by remov-ing links from a segment of chain, and replacing the links with beads. Any simple chain pattern (cable or curb) can be used, but a “ONE-three-

ONE” pattern (eg: Figaro) is preferred. The bead replaces the middle link of a “three” section (ONE-one-BEAD-one-ONE). Wire closures (“S-hook” and “figure-8”) complete the project.

MATERIALS Chain: a pattern amenable to substituting a bead for a chain link. Beads: an odd number of 5, 6, or 7mm drilled beads. WIRE: a) similar in size and color to the chain links, for anchoring the beads. b) # 20 similar in color to the chain links, for closures. TOOLS Pliers: straight and bent “chain-nose”, “round-nose”, “wire-cutter”.

Meeting Refreshments: Meeting Refreshments — Thanks to Louise Stack and Susan Carter for October’s refreshments! Elizabeth

Weston and Valerie Stathatos are scheduled for the November meeting. We need volunteers for January and February 2015. ∞ Contact me at (323) 664-9598 or by email at [email protected]. ……. Trudy Krose

The topaz has been known for at least 2000 years and is one of the gemstones which form the foundations of the twelve gates to the Holy City of the New Jerusalem. These so-called apocalyptic stones are intended to serve in protection against enemies and as a symbol of beauty and splendor. It cannot be proved conclusively whether the name of the topaz comes from the Sanskrit or the Greek, though the Greek name ' topazos ' means 'g reen gemstone'.

The ancient Romans dedicated the topaz to Jupiter and wore amulets of topaz in the belief that it would drive away sadness, strengthen the intellect, and grant courage.

The Beauty Of Topaz By Mark Nelson, Pasadena Lapidary Society

Use Caution When Buying Minerals By Mark Nelson, Pasadena Lapidary Society

Caveat Emptor - Latin for "let the buyer beware." This is, according to Cornell University Law School, a doctrine that often places on buyers the burden to reasonably examine property before purchase and take responsibility for its condition. This doctrine applies to the purchase of minerals - both in face-to-face and on-line transactions. Some dealers will intentionally or unintentionally mislabel their material as higher-valued items. One example, in the photo on the right, by John Betts, is of galena geodes from Morocco being sold as natural, while in fact these are fakes - created by gluing crushed galena cleavage fragments onto stalactitic quartz/chalcedony growths within a geode. John Betts, of John Betts Fine Minerals, advises finding a dealer that knows minerals, strives for accuracy, and stands behind the minerals he sells. “For example”, he says “all of my minerals have a Lifetime Guarantee: If a mineral specimen is ever tested, and I incorrectly identified the mineral species, I will refund the cost of the original purchase & shipping plus the cost of return shipping and the cost of the test. No dealer is perfect. Mistakes are made. I gladly accept returns when an error is made -- even if it is a specimen I sold years ago. I recommend buying specimens with no damage, or if you cannot afford an expensive undamaged specimen, you should buy specimens with no visible damage when displayed and the price should be reduced in compensation. So when buying minerals via the internet, be sure the dealer explicitly describes the damage and you should make a direct inquiry if a statement is missing (at least for specimens above $25).” The bottom line is that the Internet can be a great source for minerals and bargains, but you need to seek out reliable suppliers.

The club’s meeting raffle has been attracting some great prizes. This deep purple amethyst crystal will be the grand prize at Octo-ber’s meeting raffle.

The trip to Jalama beach was well attended with 22 total on Saturday and six on Sunday. The weather was beauti-ful with gentle breezes and a high of 75.

The campground is a long drive from the highway but the location is very pretty with a creek surrounded by lovely foliage and full of coots. We also saw a coyote, several raccoons, doves, a hummingbird, and lots of pesky seagulls.

On Saturday the group split with some going North for travertine onyx and most going south for Root Beer Agate and fossils. Lots of agate was found and numerous fossils trapped in sandstone. Jim Smith picked up a piece and split it with his hand and found a nice fish fossil.

Hailey, Paolo, Tanner, Susan Carter, Marlēnē and I broke apart a good number of pieces and found several n ice fossils including bones, fish parts, leaves and some w e c o u l d n ’ t identify.

Thanksgiving Facts & Trivia Benjamin Franklin wanted the turkey to be the national bird of

the United States.

Sarah Josepha Hale, an American magazine editor, persuaded Abraham Lincoln to declare Thanksgiving a national holiday. She is also the author of the popular nursery rhyme "Mary Had a Little Lamb".

Abraham Lincoln thought it was a good idea to unify the country after the Civil War and issued a 'Thanksgiving Day Proclamation' on October 3, 1863.

Hale’s contribution to Thanksgiving included the menu! She wrote numerous editorials stating that making a traditional Thanksgiving dinner should include turkey, stuffing, pumpkin pie, cranberry sauce, sweet potatoes and mashed potatoes.

91% of Americans eat turkey on Thanksgiving.

In the United States, about 280 million turkeys are sold for the Thanksgiving celebrations.

Californians are the largest consumers of turkey in the United States.

Thanksgiving Day is celebrated on the fourth Thursday in November in the United States.

Although Thanksgiving is widely considered an American holiday, it is also celebrated on the second Monday in October in Canada.

In the United States, the day known as Black Friday is the Friday after Thanksgiving and is considered to be the beginning of the traditional Christmas shopping season.

FIELD TRIPS By Joe Goetz

We are in for a treat! Two guided Field Trips this month! The first Field Trip this month will be November 1st and 2nd to the interesting collecting areas northeast of Barstow. We will meet in the parking lot of the Oak Tree Inn each morning at 8:00-8:30 AM. A group dinner will be Saturday at Peggy Sue’s Restaurant.

On Thanksgiving weekend we will be joining the California Federation (CFMS) at Wiley’s Well. We’ll be going with the CFMS which leads this trip annually over the Thanksgiving holiday . The dates are Thursday, Novem-ber 27th through Sunday, November 30th, 2014. This area is known to be productive for rockhounds. There is a lot of area to explore. You may even go to an area that no one has discovered and a new material will be found. For those joining us on Thursday, our Thanksgiving feast will be a potluck - prepare enough food for 8 people as everyone takes a ‘dibby dab’. With any luck the weather will be perfect to collect cutting material and a good time will be had by all. Details, directions and collectible material for both of these trips are on the Calendar page of the web site.

FEDERATION NEWS By Joe Goetz

On Napa Geology: You either felt the (August’s) 6.0 magnitude quake or heard about it on the news - involving previously unknown active fault lines as well as faults that were thought to be inactive. The valley floor has a high water table with saturated sand and silt deposits which amplified the tremors, heightening damage.

The quake opened up ground water in some bone dry creeks in Napa and Sonoma County with water levels flowing with enough water to paddle a kayak and up to 10 feet deep! Some people who had dry wells now have water — this was not due to broken water lines! Read more of Jennifer’s on-site report at cfmsinc.org and click on the newsletter for October 2014.

The answers to this month’s quiz can be found in the bulletin or on the Internet. The first Adult and Junior Members to correctly answer these questions will win a special prize at this month’s Program Meeting. See Editor’s email on page 2.

Juniors: What rhyme is Sarah Josepha Hale famous for writing?

AFMS - American Federation of Mineralogical Societies

Congratulations to Ferdie Sanchez and Nadine Ishizu for correctly answering that a Geo-site is a field trip locality geared towards educating rather than collecting specimen. Congratulations, also, to Alyson Nishimura for recognizing

the blue gem in the bulletin as the symbol of a gem show! Prizes will be awarded at the November meeting!

New Research on La Brea Tar Pit Fossils Shows Climate Change Drove Evolution of Ice Age Predators

Report by Kristin Friedrich, Natural History Museum of Los Angeles County

LOS ANGELES — Concerns about climate change and its impact on the world around us are growing daily. New scientific studies at the La Brea Tar Pits are probing the link between climate warming and the evolution of Ice Age predators, attempting to predict how animals will respond to climate change today. The La Brea Tar Pits are famous for the amazing array of Ice Age fossils found there, such as ground sloths, mammoths, and predators like saber-toothed cats and power-ful dire wolves. But the climate during the end of the Ice Age (50,000-11,000 years ago) was unstable, with rapid warming and cooling. New research reported here has documented the impact of this climate change on La Brea predators for the first time. Editor: Read the full story at

LOCAL ROCK AND GEM SHOWS

Are Minerals Safe? By John H. Betts, John Betts Fine Minerals

Asbestos - most people react in violent fear of the word. The same reaction is generated for "Radioactive". Is it safe to collect these minerals? Yes. Collecting minerals is safe, even for these types of minerals. Asbestos causes asbestosis, a disease of the lungs, when short microfibers of this type of mineral are inhaled into the lungs. When asbestos is mined, the drilling and blasting generates the short microfibers. But a specimen sitting in your display cabinet is safe. However - you should not grind it up into a fine powder and blow it around your room with a fan and then do deep breathing exercises. Radioactive minerals are safe to collect, too. Distance is your best protection against radioactivity, and it takes surprisingly little distance to be safe since the hazard drops by the square of the distance. The dose from being 6" away from a specimen is 1/36th the dose of being 1" away. Actually the biggest danger from radioactive minerals is the Radon gas generated via radioactive decay. This gas is heavier than air and collects in the lower parts of your home. Because it is a gas, it is easily inhaled where it can cause health problems. But if your home has good ventilation, you are safe. If your home passes a radon test, then you will be OK. If in doubt, store radioactive minerals in your garage. Other minerals are unsafe if ingested. If you have infants or pets that like to chew on things, prevent them from ingesting any mineral specimen. Collecting minerals is a safe hobby. There is no reason to overreact. A little education is all it takes to understand minerals and safely handle them.
