Junior Meeting (6:15 pm)
Program: Crystals come in 6 basic shapes. Bring a favorite crystal and we’ll try to identify yours. This is a requirement for Badge #1 Rocks & Minerals
General Meeting (7:00 pm)
Program: Geology—Why Bother? (A 26 minute DVD revealing that geology isn’t just about things that happened millions of years ago. It’s events going on around us every day.
Show & Tell: Crystals—What can you tell us about yours?
Hi - Thanks to all the past presidents for attending our January meeting. For those of you who picked from the list of reasons to attend our meetings, we are trying to provide the monthly programs with the items of most interest. For the Feb-ruary program, will be watching a movie on geology. (There are numerous votes for watching videos as well as learning about geology). The show and tell item will be “crystals”. What is a crystal? A crystal is a solid whose atoms are arranged in a highly ordered re-peating pattern. These patterns are called crystal lattices. If an object has its atoms arranged in one of seven crystal lattice pat-terns, then it is considered a crystal. Some examples of crystals are amethyst quartz,

SAFETY MATTERS:
SEEING THE LIGHT?
by Ellery Borow, AFMS Safety Chair If you are seeing the light, the ultra violet (UV) light that is, there may be a problem. Many of the shows I visit offer a display / exhibit / darkened booth high-lighting the amazing effects of ultra violet reactive minerals for show patrons to see. Such displays are really great to see at shows because they offer a view of minerals and rocks most folks never have the op-portunity to see. While many of the UV exhibits I have seen offer sufficient safe guards for the public, some could be better at protecting the club members working the display and the general public. In your exhibit are folks provided with sufficient eye protection and bare skin protection? Is sufficient attention being paid to reflective surfaces? Are the lights angled sufficiently well to illuminate the min-erals and rocks and keep the UV rays out of patron’s eyes? Even short term exposures to UV can have harmful effects. One of the examples I like to cite is about

WHAT THE SHAPE OF A
CRYSTAL TELLS!
Submitted by Audrey Vogelpohl
Crystals come in amazing shapes based upon their chemical structure. The shape of a crystal is one of the ways in helping identify a mineral. There are six basic crystal forms.
CUBE - shaped like a square cube. Ex: pyrite and galena
TETRAGONAL - shaped like a stretched out cubic crystal Ex: zircon and rutile
MONOCLIMIC - shaped like tetragonal but tilted in one angle Ex: gypsum and muscovite
TRICLINIC - looks like monoclimic crystals that have been stepped on Ex: axinite and tur-quoise
HEXAGONAL - looks like a six sided prism which viewed from the top looks like a hexa-gon Ex: quartz and calcite
ORTHORHOMBIC - the crystal looks like two pyramids stuck together, but at a bit of an angle Ex: barytes and natrolite

MINERAL COSMETICS IN
ANCIENT EGYPT
by Odessa Durante, WSRC Junior
When you think of Cleopatra what comes mind? When I picture her, I think of her winged eyeliner, vibrant green eyeshadow, and rogued cheeks. This Egyptian queen loved using makeup. In fact, the Egyptians were the first to create cosmetics. Those early cosmetics were actually made out of rocks and minerals.
The Ancient Egyptians treasured a bright green stone called Malachite. They crushed the stone into a fine powder and used it to give color to their eye lids. Kohl was also commonly used at that time. It was dark gray, and originally used to protect the eyes against the harmful rays of the sun. Kohl was com-posed of three different minerals. Laurionite, Phosge-nite and Galena mixed together with a few other in-gredients. It was basically homemade carbon. Finally, the Ancient Egyptians used a natural clay called Ochre, for painting their cheeks. The clay was mined and washed then dried in the sun or burnt so the pigment turned red. It is amazing to think that the first cosmetics were made from crushed rocks and minerals. Many women all around the world still use cosmetics in their morn-ing routines. Yet, many of them probably don’t know

UV reflections. Take the story of a group of people out on a boat and enjoying some sport (catch and release) fishing. Imagine that all the folks are wear-ing baseball caps with visors to protect their heads and faces from harmful UV ray sunburn effects. At the end of the day there will be folks showing no signs of sunburn because they wore the proper amount of sun screen. There are also most likely going to be folks at the end of the day who are quite sunburned, right to the very underside edge of the baseball cap where its head band touches the fore-head. How might the sun’s harmful UV rays have reached under the visor right to the persons forehead to create a sunburn in an area the should have been protected by the visor? In a word, the answer is -- reflections. The surface of the ocean is not flat, it is covered by waves. Those waves act as curved reflectors to re-flect the sun’s harmful UV waves upward and right underneath a persons visor-covered forehead. The same can happen on a smaller scale in a show’s UV mineral booth. UV can be reflected by some mineral surfaces up onto the bare skin and unprotected eyes of show patrons and club members tending to the booth. Under most circumstances the amount of exposure is relatively minimal, except for those who remain in the booth for extended periods of time - such as the folks tending to the booth and those curious show patrons who just can’t get enough of the beauty and curiosity of UV illuminated minerals. Some suggest-ed solutions to UV overexposure include:
Wear eye protection for extended viewing or working in the vicinity of UV light
Wear sunscreen protection on exposed skin
Minimize reflections of UV light toward viewers - reflections may come from the display material and / or the minerals themselves
Angle the UV lights so no one, especially small children, can kneel down and look up into the UV lamp housing or bulbs
Offer protective eye-wear temporarily to patrons who wish to use it, even if for short exposure times
Take periodic breaks from being under strong UV illumination
We encourage shows to offer exhibits of UV miner-als and rocks because such displays always seem to be a great attraction. We also encourage sufficient protections and safeguards be utilized with such ex-hibits. As always, we hope you safely see the light because your safety matters. (via AFMS Newsletter, 2/17)

(Continued from page 7) cause they can encourage unsafe driving speeds, dam-age suspension systems and increase road mainte-nance costs. It also creates a safety problem, because a car or truck that doesn’t experience full contact with the ground might not be able to brake properly. So what causes washboard Roads? Physics of Washboard Road Formation Some experts who maintain dirt roads say that your car’s suspension system causes the problem as it actu-ally tries to smooth out the bumps in the road [source: U.S. Forest Service]. As a wheel moves over a bump, the suspension system absorbs the shock and then pushes back against the road surface. On a soft sur-face like a dirt road, the push back either packs or displaces the dirt it hits. Over time, as more and more cars go over the bump, the washboard pattern devel-ops. However, in the summer of 2009, physicists from Canada, France and the United Kingdom published a new study about the physics of washboard road for-mation. They discovered that ripples will form, even when the springy suspension of a car and the rolling shape of a wheel are eliminated [source: American Physical Society]. They built an experimental vehicle, replacing the wheel with a suspension rolling over a road with a simple inclined plow blade, without any spring or suspension, dragging over a bed of dry sand. Ripples appear when the plow moves above a certain speed. After observing the results, they compared this phe-nomenon to the physics of stone skipping: A stone needs to be thrown above a specific speed in order to have enough force to bounce of the surface. A wash boarding plow is similar, except the sandy surface remembers its shape and the effect is amplified. They concluded that the formation of a washboard pattern is inevitable. The ridges will form, even if the wheel diameter, suspension or surface is changed. The only way to avoid the effects of a washboard road is to stay below a certain speed, but that’s impractical: you’d usually have to drive at 3 miles per hour (4.83 kilometers per hour) to eliminate the problem alto-gether. Some day, such discoveries may lead to improved suspension systems or improved road surfaces that smooth out a bumpy ride. In the meantime, there’s not much you can do about washboard road except brace yourself, watch your speed and hang on for the ride. Causes of Washboard Road Formation While washboard roads can occur anywhere, they are most often seen in hot, dry areas and on sandy, dirt or gravel roads. What causes wash boarding to be worse in some locations than others? There are three main

WHAT CAUSES WASH-
BOARD ROADS?
by Marie Willsey
HowStuffWorks.com, ADVENTURE | RANCH LIFE Have you ever driven down a back road and suddenly felt like you’d just ran over a series of speed bumps? Did you wonder what they’re doing in a road that seems to be in the middle of nowhere? The phenomenon you’ve experienced is what’s called a “washboard road.” When a car travels on an un-paved road, a wavy pattern will ultimately develop. At first, tiny ripples form, and then they get larger as more cars pass over them. Whether you’re traveling on roads in Australia or Africa, South Dakota or Southern California, washboard roads -- with a wavy pattern that resembles an old-fashioned metal wash-board -- are a common occurrence. While washboard roads are familiar to drivers on country roads around the world, the phenomenon oc-curs elsewhere in science and technology.
Whenever a sideways force acts on a malleable sur-face, ripples occur. You may have seen the same little ripple on wind or water-driven sand at the beach, and on moguls that develop on ski hills. Motocross bikes and snowmobiles also cause ripples to form in dirt and snow. Small bumps on steel railway tracks are also a result of the washboard phenomenon. Washboard roads often are more than a nuisance be-

causes: Lack of moisture -- Washboard roads are particularly prevalent when weather conditions are dry. Frequent rain fall reduces the chances of wash boarding. Traffic -- Hard acceleration or braking can accelerate wash boarding, and that helps explain why you’ll see it frequently at intersections, before and after sharp curves, business entrances, and even driveways. If a car’s tires lose a firm grip on the road and begin to spin or skid, some gravel will be displaced. If this happens repeatedly, the gravel will be displaced, often uniformly, and a washboard pattern will form. Poor quality surface -- Wash boarding occurs most frequently if the sur-face quality of the road is poor, whether it’s sand, gravel or even pavement. When a heavy load passes over the surface repeatedly, it develops irregularities like washboard patterns. Potholes are a common re-sult of poor quality surfaces, too. If you travel dirt roads frequently, you know that you can find an ideal speed that will help smooth out the ride. That’s the speed at which your car’s suspension system is pushing the car down at the same time you experience a dip in the road. The problem is that the more the tires press down, the worse the washboard depression becomes. It’s a catch-22: your suspension system is giving you a smooth ride, but it’s making the washboard problem worse. http://adventure.howstuffworks.com/outdoor-activities ranch-life/what-causes-washboard-roads.htm (via Agatizer, 1/17)

PYRITE AND FOSSILS
PYRITE Pyrite is a Sedimentary Mineral. It is found in the following colors: gold, silver and rusty/oxidized (brown, black, red or green). Pyrite is nicknamed 'Fools Gold' because during The Gold Rush in the mid-1800s, it was mistaken for Gold. Pyrite is found in a complex of different Cuboids; they overlap, so you may see one cube with the corner or edge of an-other cube appearing to protrude from it. PYRITE AND FOSSILS Fossils are sometimes found preserved in Pyrite. Py-rite Fossils are preserved in immaculate detail. They weigh significantly more than normal Fossils. Some-times a Fossil can be partly preserved in Pyrite. (Don't
try to dissect your Fossils in search of Pyrite as it is unlikely you will find it!) Pyrite Fossils are normally found in large quantities, called Pyrite Veins. Photo Below: Pyrite Fossilized Ammonite
