April 2019 Program

What “Inside-Look” Does a Petrified Log and a Living Tree Have in Common? 
Presented by: Walt Wright
Living trees can be identified by their flowers, fruits, leaves, and wood. Few people have ever thought of wood as anything but “wood.” Wood has structure that is as characteristic as the flowers or leaves on a tree. But who cares? People see furniture, paneling, cabinets & flooring that appeals to them but have no idea why it is appealing. And that is understandable because the longitudinal surface that they are looking at has few distinguishing features. It is the cross/transverse section of the wood that is diagnostic. They never look at the end of a 2x4. Trees have a long geologic history going back some 390 million years. That structure in the early trees has come down to the present with modifications. Thus, when looking to identify fossil wood, one must be familiar with living tree structure. Fossil classification has to be consistent with that of living organisms.

            We will, in an hour, try to understand the different woods of today in order to understand the woods of long dead trees. Walt has generously agreed to attempt to classify one (1) piece of petrified wood for each person in attendance. It must be a polished piece in order to identify the cell structure. Please bring only one (1) piece per person.

            The Rockhound Dennis Miller Show                                   At the April meeting, Dennis will focus on the color Green. Think Emerald, Garnet, Dioptase, Diopside & Turquoise to name a few. Bring in your Green specimens and put them on Dennis’s table, let him know what it is and he will talk about it to the membership or you can talk about it yourself if you’re not too shy to step up. Dennis will be giving something from his Goodie Box to each member or guest who brings in something Green.                                                                                               Chris Ward, Bulletin Editor
April Birthstone: Diamond

You probably already know of the diamond’s toughness. In fact, it’s the hardest gemstone and is made of just one element: carbon.
Its structure makes it 58 times harder than anything in nature and can only be cut with another diamond. While it’s become nearly synonymous with wedding engagements, it’s also the perfect stone for individuals who want something that’s just as appropriate for everyday wear as it is for special occasions.
Diamonds come in several colors, including yellow, red, pink, blue, and green, and range in intensity from faint to vivid. Generally speaking, the more saturated the color, the higher the value.
In fact, diamonds sparkling with intense color are rare and may be priced higher than a colorless diamond of equal size. Because fancy-color diamonds are very desirable, color is sometimes introduced in a laboratory. These are correctly called color-treated diamonds.
Its unique physical properties mean it has the best possible luster of any gemstone when cut and polished well. So, if you’re in the market for “sparkle,” the diamond is the gemstone for you.

Pebble Pups Program for April

This month, at our general meeting, we will be teaching our youth group how to create, identify and label a beginner’s rock collection. We will touch upon the Moh’s Scale of Hardness and how to identify the three main types of rocks; Igneous, Metamorphic and Sedimentary. For those in the youth group who have already completed this activity (Noah & Kai) we will have a new Leadership activity for them to complete.
Our July 2019 meeting just so happens to fall on July 4th this year. Therefore, due to the long holiday weekend, our July meeting has been moved to the second Thursday, July 11th.  The location of the meeting has yet to be determined but it definitely will NOT be at the church. We will still be having our Ice Cream-Bingo Social as is our July tradition. The Board is diligently working on finding the perfect summer location for this event and will advise the membership well in advance of July so you all can make the necessary adjustments in order to attend. 
Del Air Board of Directors 
Chris Ward & Bob Knox and Bob & Maxine Dearborn worked the National CFMS Show & Convention hosted by the Pasadena Lapidary Society over this past March 8th weekend at the Pomona Fairplex. It was quite a successful show with hundreds and hundreds attending. Bob & Chris worked the entire show and Bob & Maxine worked the whole day on Saturday. We spoke with many people and handed out our club flyers and played our educational Tooth & Egg games with all the children. Our Volcano and Sedimentary Rock displays can next be seen at the Conejo Gem & Mineral Society’s annual show on Saturday & Sunday, April 13th & 14th.  We encourage all members to attend and see first-hand exactly      what we do at these shows. You won’t be disappointed.

The Del Air Club Talks Dinosaurs

We were invited to Porter Ranch Community School Book Fair to talk and show our Dinosaur stuff. And we did just that!

Members Shellie VanWinkle, Bernadette
Friedman, Russ & Aileen Beckers, Ann Richardson and Bob & Maxine Dearborn put up a 4 table display of our Dinosaur skulls, bones, claws and poop. We even had a dino that growled at our visitors!

We had a lot of fun for two hours and spoke to many,
many people about our display and club. We even signed up for another classroom talk.  A big Thank You to Ann Richardson for getting us into this event.
