Minutes of the VGMS Regular Monthly Meeting;
Wednesday, February 28, 2007:
The regular monthly meeting of the Ventura Gem & Mineral Society was called to order by Ed Clark at 7:30 pm on Wednesday, February 28, 2007, at the Lexington, Ventura, CA.
The January membership meeting and the February board meeting minutes were corrected and then m/s/c as shown in the bulletin.
Ed Clark welcomed everyone and directed members in the pledge to the flag. Next, Ed reiterated the need for help at this year's annual show which is only days away. Sign up sheets are on every table so as to give us an indication of the numbers we'll have to man this show.
Richard Bromser gave the treasurer's report and it was m/s/c to accept it as stated. Richard also stated that our 2007 show plans were progressing well and hopes are for another very successful year. Richard & Shirley will be relocating to Texas in March and the club desperately needs someone to take over duties of the treasurer. Anyone willing to help out should contact Richard or any board member.
Mary Polacek - The 10th of the month will again be the deadline for articles for the March bulletin.
Ron Wise - Upcoming field trips will include Bob Fitzpatrick's venture for thulite on March 30-April 1st. This is no joke!
Florence Meisenheimer - The CFMS show for this year will be held at the Palmdale fairgrounds right off of Highway 14. Paradise may have to relocate in the future and a possibility would be Hope, California. More information is expected shortly.
Ray Meisenheimer - Ray will be providing a fossil and mineral demonstration this month somewhere for sure.
Wayne Ehlers - We'll need everyone's help with security when they're not working booths during the show. Wayne also reported that there's still no word from Help of Ojai as to whether they can help us with a new museum location. We're keeping our fingers crossed.
Jean Wise - Lots has been done for the kids' booth at this year's show but now we need volunteers to sign up and help man it and hand out all these wonderful prizes.
Jim Brace-Thompson - The Star's Community Section had a nice write up for our show in Friday's paper.
Lowell Foster - Upcoming presentations for monthly meetings include Ed's mineral identification for March, a silent auction for April and a film in May. Lowell next presented members with their "finds" from Quartzsite, including Jim Brace-Thompson's opal book, tools, jaspers, agate from Agate Creek, Australia, quartz with phantoms and calcite. Nancy Brace-Thompson displayed petersite, imperial jasper, sun stone and opal from Lightening Ridge, Australia.
Abe and Esther Barshai provided refreshments.
The next board meeting will be held at the fairgrounds, on March 1st, at 6:00 pm and the next regular meeting will be held March 28, 2007 at the Lexington in Ventura.
There being no further business, Ed adjourned the meeting at 8:15 pm.
Respectfully submitted,
Greg Davis,
Recording Secretary.

New business:
Richard Bromser - Printed copies of the monthly financial statement were issued, reviewed and it was m/s/c to accept the financial statement as printed.
Shirley Bromser - Our club has 46 members as of this date. It was m/s/c to accept membership applications from Cynthia Day, Carl Stephens and Elizabeth Nightlinger.
Shirley Layton - Country store items will be accepted right up until the last minute for our annual show.
Florence Meisenheimer - Zzyzx will take place March 18 through the 25th. After this, our 45th annual VGMS show, all eyes will be on Palmdale and the CFMS show in June.
Mary Polacek - The 10th of the month will still be the deadline for articles and submissions to the bulletin. In the near future it will be changed to the first weekend after the board meeting. The new directories will be printed up in late March.
Here's to a successful show!
The next general meeting will be on March 28, 2007 at the Lexington in Ventura.
There being no further business, the meeting was adjourned at 7:00 pm.
Respectfully submitted,
Greg Davis,

Plant Sale:
We had eight tables (each table was 8') of plants to sell on the Saturday morning of our show. By Sunday at 4:00 pm, all that remained was less than one table of plants.

Kids' Booth:
This was an amazing success this year. It was so popular, I had trouble seeing to the table all weekend!! Thank you to Jean Wise and Lowell Foster for bringing it all together, and their dedicated volunteers Sharon Hixson, Esther Barshai, Heidi Mauer, Miriam Tetreault, and Jim Brace-Thompson. These folks did an outstanding job.
The Kids Only Raffle Winners were:
Luke Dewitt (Newbury Park), age 9, 4th grade.
Sergio Valdez (Port Hueneme), age 9, 4th grade.
Angelina Suarez (Simi Valley), age 4.
Nandi Isara.
Lowell reported he was very pleased being spontaneously approached by Marina West students (and not just from his class), saying how much fun they had at our show.
Great Job Jean and Lowell!!
Special Thanks:
VGMS would like to extend a special thank you to Donna and Larry Knapton. The Knaptons generously donated their weekend to spotlight the wonderful Rock Box Project. They displayed samples of the Rock Boxes, and accompanying teacher literature, that have been offered to the Ventura County public schools. In addition, they also gave to any teacher who inquired their own rock specimen. This was a very busy display and it kept Donna very, very busy. Thank you both for your dedication to the youth of our community.
There were a lot of teachers at the show this year!!! Thanks to Nancy Brace-Thompson and Valli Davis for getting the word out to the educational community.
Jim Brace-Thompson did an incredible and effective job as Publicity Chair.
Country Store:
Thank you Shirley Layton and volunteers Sharlyne Holloway, Sharon Cunningham, and Shirley and Richard Bromser. The club will sorely miss Shirley Layton's Country Store. She has made it special for many years.
Thank you Dave Mautz, Wayne Ehlers, Stuart Bloom, Abe Barshai for security. Special thanks to Dave and Ed for their "cot" duty.
Thank you Shirley Bromser and Nancy Brace-Thompson for stocking the kitchen, and to all who brought in goodies to share.
Thank you to the volunteers for setup and breakdown: Richard and Shirley Bromser, Greg Davis, Ron and Jean Wise, Dave Mautz, Jim and Nancy Brace-Thompson, Mel and Sharon Hixson, Miriam Tetreault, Heidi Mauer, Mary Polacek, Kathryn Davis, Ed Clark, Shirley Layton, Steve and Sharon Mulqueen, Jenna Mast, Miriam and Craig Andrews. Many hands made the work fun (??!!)!
If I have omitted any of our valued volunteers' names it is only due to memory lapse. We sincerely appreciate EVERYONE'S CONTRIBUTION!
THANKS TO ALL OF THE VOLUNTEERS!!
YOU MADE 2007 A SPECTACULAR SHOW!!

Lapidary Class:
Would you like to learn how to cut and polish rocks? Come to our lapidary class for a hands-on experience in cutting and polishing rocks.
The class will be held on Monday evenings from 6:00 to 8:30 starting March 26, and will last 5 weeks until April 23. Bring your own rock or slab if you like, but there will be plenty of slabs there for your use. We will be using the slab and trim saws and our grinding and polishing machines.
This is probably our last class at this location. We hope our possible new location, if it becomes available, will have space for even a larger workshop.
The workshop is located at 5019 Crooked Palm Road just off Highway 33 going towards Ojai. Take the Shell Road exit. Turn left to Ventura Avenue. Turn left on Ventura Avenue. About a half mile down, turn left on Crooked Palm Road. Go under the highway and parallel the highway for about a half mile, and 5019 is a little brown building on the left at the corner of the old Petrochem refinery property.
If you want more information call me at 482-6830, or Greg Davis at 647-9214, or Ron Wise at 647-4393. We hope to see you there.

Photos and Report by Randy.

Picture 29 is my very first ever lapidary project. It has been shaped but not polished yet. I adjusted the colors to try to match the actual sample. I think this is a good one for 2 reasons: 1) As a geophysicist I have had geological training and I learned to look for the small indications. 2) As a former hunter I learned to look for the PIECE of the animal, a hoof, or tail, or eyes, not the whole creature (I'm past the killing thing now).

I looked for the best pink I could find in little pieces of float. It was a virgin part of the hillside, although from the Google earth satellite images, I think I can delineate a zone of overall alteration, and some others within 3/4 mile. I also know that you have to get below the soil to un-weathered rock. At that spot I started to dig. Fortunately, what I thought was another float rock was a bit of native outcrop, about 3 inches under the surface. I dug here and found the piece you see and some others 10-20 pounds that I could get with a rock hammer and no other tools. I guess I have accepted being a pack mule years ago to get samples back to camp.
I remember the location. We could get some serious samples if we go back with a 5' pry bar, a 12'' gad and a sledge; assuming we can't use a drill and explosives [legally].
I estimate this sweet spot from the float to be about 6' N/S by 2' E/W, maybe 3 ft deep (an educated guess). I know that metamorphic alteration usually comes from depth, so the depth may be more that I estimate; but who wants to get into hard rock mining?
Best Regards, Randy.

Pre-polish for Faceters: Faceters pre-polish at 3,000 and finish at 50,000. If you use 8,000 diamond to pre-polish, your material will pit and take 10 times as long to polish!
Via Pegmatite March 2007 via John Franke of the Facet Shoppe.
Removing Lacquer: Ever want to remove a lacquer coating from an otherwise nice piece of lapidary material? Want to avoid using harsh chemicals? Here is a tip for you. Obtain some apple cider vinegar, the brown colored kind. Submerge the lacquered object in it, leave for a week, then remove and scrape off the lacquer with your thumbnail or other appropriate blunt tool. Repeat if necessary.
Via Pegmatite March 2007 (SDMGS member Mary Jane Dunn says it really works!!)
Robyn Hawk asked: What can I do to prevent undercutting and how, if possible, avoid it altogether. I am cabbing a piece of Death Valley Picture Jasper and am having so much trouble with it.
Steve Ramsdell replied: The easy way is to use all diamond equipment. Diamond cuts everything softer at just about equal rates. The hard way for us cheap skates is to start hand sanding after the rough sanding. Start with 220 grit and work your way up. Use sand paper wet on a felt or soft rubber pad. The pad helps get rid of flats. Rinse between grits just like usual. If you use an oxide polish, use a lighter touch. Some stones can show an undercutting at this stage.

New Forest Road Plans For All National Forests in the U.S.
By Shirley Leeson & Dee Holland beauholland@salmoninternet.com and shirleyleeson@msn.com.
Our most recent information on hearings was for the Stanislaw National Forest, public hearings were held in February and March, but contact your local forestry office and ask for information immediately. Get your name and email in their system.
We attended the 2nd round of Forestry Public Forums on Road Closures in our Salmon/Challis National Forest up here in Idaho. The first meetings were last summer, and these meetings, if Blue Ribbon hadn't contacted us, were not published. None of the local people knew about the meetings till we contacted the local 4-wheel drive dealership and the taxidermy, hunter and fishermen's businesses. They were astonished they hadn't been informed.
We found the following: Plans were already underway. They had huge forest quadrant maps with roads already in red for open (at the moment) and black, proposed closures, and blue, private or county roads.
The Forestry people were friendly and helpful, but cautious. We got lots of printed material. The one for us that was the most important was a paper with the following: For each road, trail, route or area that you would recommend for addition or deletion to the designated system of open motorized use, please provide the following information:
| Forest System Road or Trail #_____. User-Created Route Description, please give geographical name ie: Deer Creek, and description beginning and end points. Why should there be a change in the existing Travel Management Plan? What is the condition of the road/trail/route that is being proposed for addition or deletion? Would you expect any environmental concerns over this addition or deletion? Please describe. What social conflicts might occur if your proposal is adopted? Will someone else's recreation experience be harmed by this addition or deletion? Name, Mailing Address and Email at the bottom of the page. |
For each road or trail, there must be a worksheet made out. Dee is in the process of checking each road and trail.
There will be another meeting in town next Wednesday, and we have alerted a number of people to attend. Again, this wasn't published and when I asked why they said they thought they had enough emails from the first meetings, so didn't bother and that's what we're dealing with.
Dee Holland has been sending information from the Blue Ribbon Alert System to all those CFMS members who we have emails for. Unfortunately, that's not too many. If you are interested in being a part of this National Forest Road Closure process, send us your email and we will alert you to information going on in your area. If you received something from Dee Holland or Shirley Leeson, and you can't attend, please make sure someone will represent rockhounds. We must get the fact that we exist out there to the Forest people.
The BLM is also doing a "Management Plan Program". There were meetings for Riverside, Imperial Counties and Yuma County in Arizona recently. This is an area of real concern to CFMS rockhounds.
Will alert you to more when we have it.

To begin I will quote from the AFMS Code of Ethics, "I will keep informed on all laws, regulations and rules governing collecting on public lands and will observe them. I will, to the best of my ability, ascertain the boundary lines of property on which I plan to collect."
It is the responsibility of the fieldtrip chairperson to do the footwork mentioned before having a fieldtrip. I have normally used the BLM office in Sacramento to begin this process. One cannot go to the BLM in Hollister for this information because there is no computer for public access.
From my experience it is important to determine the Township, Section and Range of the purposed site. This is of course when it is public land. Land status can change so status should be checked up to date.
Obtain a surface management status map from the U.S. Department of the Interior Bureau of Land Management, California State Office, Sacramento, CA 95825 . Open the large map on a table with plenty of room and locate the site. Look at the west and east borders of the map. You will see a capital "T" with a number of the Township and a letter of direction, N or S. The number of the Township corresponds to the south of the line to the next Township line and west to east across the map.
The Township lines are thicker than section line borders and run horizontally west to east. Determining the Township is the first step in determining the Township, Section and Range of the purposed fieldtrip. Once these co-ordinates have been established and the exact site and its boundaries are found, then with the help of the BLM, the status of the land may be ascertained.

Looks like things are heating up again in the US Congress pertaining to our collecting rights. I've just been sent the following information from Jon Spunaugle, ALAA Executive VP for Legislation. During the last session of Congress we were able to get the House bill "killed" through swift action by a rockhound member.
Unfortunately this will not be possible again this year due to the manner in which the bill was introduced.
Let's get the word out and contact our Representatives and Senators sooner rather than later urging a vote AGAINST this legislation.
Remember that fossils today could well mean minerals and cutting rough tomorrow. Also do not forget to include a letter to Speaker Pelosi who can determine when this bill is brought out of committee and onto the House floor.
Here is Jon's message. You can read the full text of HR554 at http://thomas.loc.gov/, type HR554 in the box labeled 'Search Bill Text', click on the circle next to 'Bill Number', and then click on 'SEARCH'. (By the way, if you received Jon's original e-mail, he had the bill number listed incorrectly. The correct Bill is HR554).
Fossil Collecting Bill introduced into the US House January 23, 2007.
"On January 18, 2007 a Fossil Collecting Bill HR554 'Paleontological Resources Preservation Act' was introduced into the US House of Representatives by Congressional Representatives McGovern of Massachusetts and Renzi of Arizona. It was sent to the Committee on Natural Resources and Agriculture for a period of time to be determined by the Speaker of the House. (This means that regardless of what the Committee Chair people do, the Bill can be brought to the floor of the US House for a vote at any time with or without amendment or Committee recommendation.)
"Preliminary examination of the actual Bill language suggests that it is very similar to the Bills introduced and passed by the U S Senate in past years. Casual collecting would be allowed as seen appropriate by the government land managers. Provisions for civil and criminal penalties remain in the Bill as does a rewards section for information on possible violators and other property confiscation including all paleontology resources."

We Should Be Aware of Safety At All Times
By Chuck McKie, CFMS Safety Chairman 2007.
There are many people new to rock hounding and some of the older ones might need a little reminding. Lots of us will be going on field trips whether singularly or in groups.
Start by making sure your tools are safe.
Chisels: Heads of chisels should not have any mushroom heads. If the heads are rounded over with fingers (jagged pieces of metal) sticking out from the head of the chisel, grind them off even with the head of the chisel. I carry a piece of metal in my arm that flew off like a bullet - from a mushroom head when I was beating on a chisel to beat off a ball-bearing from an axle. It could do the same to you if you were trying to break a rock.
Sledges: Use a size you can handle. I have a 1#, 2#, 4#, 6#, and 8# sledges. There are even larger ones. Be sure the heads are tight on the handles. You can obtain little pie shaped pieces of metal from hardware stores which can be driven into the wood of the handle where it goes through the head.
Hammers: The same applies to hammers.
Rock picks: Most rock picks have handles formed from the same metal as the head. Do not use your rock pick to beat on a chisel. A rock pick is designed to beat on a rock, not on metal.
Safety glasses: Always use safety glasses when striking a rock or a chisel. A little flying chip can put your eye out in a heart beat. If someone else is striking with a hammer or a sledge, and you are near-by, be aware, turn your face away, wear glasses, and or move away. You, as a wielder of a hammer/sledge, must be aware of others in your vicinity and wait for them to move to take preventative action.
Gloves: Use heavy gloves. When holding a chisel, especially when you become weary, you may miss the head of the chisel and hit your hand. THAT HURTS! We all do that. A heavy glove helps cushion the blow to your hand and helps to lessen the damage to your hand. A good idea is to take a short section of a garden hose, insert your chisel through the one end of the hose, and hold the other end of the hose.
Shovels, rakes, hoes: Tighten the handles, maybe drive a nail or a screw through the metal where the wood enters the head. You might have to drill a small hole in the metal.
Shoveling, raking, hoeing, tossing rocks out of your way: Be certain that no one is in the path of your refuse or below you out of sight. DO NOT dig under a large overhang. If an overhang were to collapse upon you, you could suffocate before anyone noticed your predicament.

Proper Use of Chemicals.
Know the proper use of chemicals:
Keep all chemicals out of reach of children, and you yourself learn the right antidotes for each poisonous substance you use.
Remember that many acids and some alkalis are corrosive or caustic. Learn the difference between corrosive, caustic, flammable, injurious and poisonous chemicals. Learn the first-aid procedures that apply to each class of chemicals that you use and come in contact with.
Be careful what you lick or taste, especially before you know what it contains. Arsenic, mercury, selenium, some of the boron minerals, and some sulfates are very poisonous.
Be sure of sufficient ventilation in cleaning and testing materials. This applies to bead tests, tests with acid and other chemicals. It is advisable to wear a mask besides having proper ventilation when dry sanding mercury, arsenic, copper, selenium, and silica minerals. Abalone shell when worked dry can make you very ill, without enough ventilation.
Use care in handling radioactive minerals with bare hands, especially taking care not to breathe in the dust. Spray radioactive minerals with several coats of lacquer to prevent dusting and flaking. Handle with a pair of tongs when not placed in an oversized bag, keeping at least an inch between the radioactive specimen and the wall of the box.
Wear safety goggles or shatterproof glasses when breaking rocks to avoid eye injuries. Always wear a mask if you do not have a way to remove injurious dust or fumes. Watch out for sharp tools and blades without proper guards in the equipment.

Definition of the Month.
Lakester - Also known as a "Lake Racer", an automobile custom built for racing on desert dry lakes. Dry lake racing began in the 1930's on the dry lakes of the California Desert and at the Bonneville Salt Flat in Utah. The sport consisted of drag racing on the naturally level surfaces of the hard mud or salt flats common in enclosed basins in arid regions. Drag racing in the United States was born on dry lakes long before drag strips were developed. During World War II, gasoline, lube oil and other supplies became scarce, causing the sport to cease temporarily. Also, most of the race drivers became involved in the war effort. By 1946, when fuel and lube oil became readily available, the sport reemerged. Two of the most popular sites for racing competitions in California were Muroc Dry Lake (now known as Rogers Dry Lake, currently Edwards Air Force Base, Kern County) and El Mirage Dry Lake (northwest of Victorville, San Bernardino County). Muroc provided 12 1/2 miles of continuously flat straightaway while El Mirage was approximately 5 miles in length.
Most of the early lake racers were modified Model "A" vintage auto bodies with souped-up engines. Auto bodies were altered in order to reduce vehicle weight and wind drag. Quite often, fenders, bumpers, spare tires, roof, back seats, engine hood, trunk cover and other non-essential parts were removed to create a "bare-bones" jalopy. After World War II, auto bodies were aerodynamically redesigned to reduce the affects of wind drag. One famous Lakester body design involved the use of a tear-drop shaped auxiliary "drop tank" (an external, expendable airplane fuel tank made of aluminum) that was used during the war on Lockheed P-38 aircraft. This technique incorporated aerodynamics with a light-weight design in order to maximize speed on the lake bed. Many innovations in drag racing began on the dry lakes of the Mojave Desert.

Look at a relief map of California; one that shows the location of our principal mountain ranges. Everything east of the great mountain ranges that run from the Oregon border to Baja California (approximately one-third of the state) is classified as desert. These deserts have one thing in common: drought. If an area gets less than ten inches of precipitation per year, it usually is considered to be a desert. Mountain ranges form a barrier that intercepts the precipitation from Pacific storms so that the deserts lie in a "Rainbow Shadow". What differs in California's three deserts is the average temperature, the time of year most of the precipitation falls, and the major form of the precipitation.
Our most northern desert is the Great Basin. It lies between the Cascades and the Sierra Nevada on the west and the Rocky Mountains on the east. Only the western edge is in California. It includes the Modoc Plateau, the Mono Basin, and Owens Valley. Because the Great Basin is so large, it has been said that Great Basin Sagebrush is the most common plant in the Western United States.
South of the Great Basin is the Mojave Desert. It is classified as a warm desert because most of its precipitation falls as rain, but at higher elevations along the edges of valleys it still gets a significant amount of snow. The Mojave includes an area east of the southern Sierra Nevada and the Transverse Ranges, including the San Gabriel and San Bernardino Mountains. It also includes southern Nevada, north-western Arizona, and south-western Utah. It is called the "high desert" because parts of it lie above 3500' elevation. However, the northern boundary of the desert has several finger-like extensions, Panamint Valley, Saline Valley, and Eureka Valley, which are of low elevation. You will find the Creosote Bush and Joshua Trees disappear from this scenery.
The Colorado Desert is our southernmost desert. It is the warmest of our local deserts by virtue of two factors, its southern position and its low elevation. Much of it lies at sea level or below. About half of its precipitation arrives during the summer, usually as thunderstorms.
The Colorado Desert is part of a larger southern desert known as the Sonoran Desert. California's part of the Sonoran Desert lies west of the Colorado River and extends northward to the vicinity of Needles, California. It includes the lowlands of the Salton Trough, a region of subsidence along the San Andreas Fault, and south of the Little San Bernardino and Eagle Mountains, it extends eastward toward the Colorado River.
Finally, it is the Colorado Desert that seems to produce the most spectacular display of annual wildflowers, particularly conspicuous in the dunes near Palm Springs, Borrego Springs, and east of Twenty-nine Palms. These are annuals or ephemerals. They need at least an inch of rain early in the winter (by October) and then a lot of sunshine.

Jerry: I vaguely recall from a course I took many years ago (Gas Dynamics or Aerodynamics) that this is called a "Condensation Shock" wave. Any explanation from my old Lockheed Martin (Martin Marietta) buddies?
Dick Keenan responded for your information: The clouds appear for the same reason that clouds always form, namely, that the air has cooled to the point that the ambient water vapor condenses. Flows around bodies and wings always change the temperature and pressure of the fluid. Lift is caused by pressure differences on top or bottom of a wing or body. The pressure varies from point to point in a flow around an object. Temperature changes can be seen by noting that most fluid flows (and nearly every aerodynamic flow) are frictionless. In the language of thermodynamics, the flow is said to be reversible or loss-free. As a result, the entropy of the flow is a constant, and the temperature (T) at each point in the flow is necessarily related to the pressure (p) as follows: T a p(g - 1)/g for low pressure gases. The constant g is the ratio of specific heats. For air, g = 1.4 and the exponent on the pressure (p) in the above equation is approximately 0.29. Thus, the temperature of the air will increase and decrease as the pressure increases and decreases. Regions of high pressure will necessarily correspond to regions of high temperature and regions of low pressure will correspond to regions of low temperature.
I thought everybody knew that!
Editors Note: This page is sourced from an email I received from Jerry Anderson. I worked for Jerry at ARCO Solar where he developed encapsulation for solar modules. He is currently retired and living a good life in North Carolina (his garage is 3X the size of my house!). He emails a lot of neat stuff, some of which I cannot help but share with you. I am introducing him because no doubt you will see his byline frequently. I also worked for Dick Keenan at ARCO Solar. Jerry worked on the Apollo program. Dick and Jerry shared a few space adventures together at Martin Marietta. Quite a duo. Very smart and very funny!

Indonesian engineers temporarily halted an attempt to plug a fissure that has been gushing mud for nine months, after a steel cable hoisting concrete balls into the crater broke Saturday [February 3, 2006], officials said.
The hot, noxious mud has displaced 13,000 people and covered dozens of factories and thousands of homes. The mud has blocked major roads into the country's second largest city, Surabaya.
Over the next few weeks, authorities plan to drop nearly 1,500 concrete balls, weighing up to 500 pounds each, into the geyser. A string of four balls was successfully lowered into the hole Saturday in heavy rain and wind, said Rudi Novrianto, a spokesman for a government task force handling the disaster.
"Thank God, we have managed to drop one chain, equipped with sensors to monitor pressure and depth," he said.
Officials had hoped to drop from five to 10 strands of balls into the mud volcano Saturday.
If successful, the project will decrease by up to 70 percent the volume of mud now being channeled by a system of dams into a nearby river and out to sea. The mud has been surging at a rate that could fill 50 Olympic-sized swimming pools a day. Critics, however, doubt the project will succeed and warn it could be dangerous or that deep underground pressure could push the mud up elsewhere.
Mud fissures occur naturally along volatile tectonic belts like the one running below Indonesia, the world's largest archipelago.
However, opinions differ about the cause of the latest rupture. Independent geological studies suggest it was triggered by faulty gas exploration techniques by operator PT Lapindo Brantas, which created fissures in a bed of porous limestone. Other research supports the company's assertion that it was a natural disaster resulting from increased seismic activity following a major earthquake two days before the mud began flowing.

A space rock the size of a large mountain hit 1.8 billion years ago and dredged up part of Earth's lower crust, essentially turning a bit of the planet inside out, a new study concludes.
Earth's upper crust is about 22 miles (35 kilometers) thick. Scientists have debated how deeply into the crust the shock wave from a large asteroid could penetrate. All the way to the next layer, it appears.
The evidence comes from a crater in Sudbury, Ontario. Most of the crater was long ago folded into the planet or eroded away. But a section is exposed, revealing minerals and other features that can be compared to more recent craters that are more intact. From all this, scientists gleaned clues to the catastrophic impact.
It appears an asteroid about 6 miles (10 kilometers) wide hit the planet at more than 89,000 mph (40 kilometers per second).
"The impact punched a hole to the very base of the crust and the meteorite itself was probably vaporized," said University of Toronto geologist James Mungall, who led the study. Much of the heating and damage is done by a shock wave that compresses material ahead of the impacting object.
A plume of superheated rock from deep down surged upward and landed on top of the impact site, creating the melt layer visible today.
In a telephone interview, Mungall explained that in the top layers of the Sudbury structure, his team found relatively high concentrations of iron, nickel and platinum, stuff that is more common in the lower crust of the planet than in the upper crust (the elements exist in just trace amounts in both regions). The lower crust sits atop Earth's mantle, which surrounds the core.
"Since it ended up on top, it effectively inverted the layering of the crust," he said. "It had not really been appreciated that large impacts would selectively move material from the bottom of the crust up to the top."
The top layers were also relatively depleted of zirconium, uranium and other elements that tend to show up in other impact sites that only involved melting of the upper crust.
The results were detailed in the June 3 issue of the journal Nature.
Mungall's team also found an enrichment of iridium in the overlying layer at the Sudbury complex, which was already thought to be part of an impact crater. Iridium is commonly associated with extraterrestrial rocks and is a strong indicator of an impact. The crater was initially more than 125 miles (200 kilometers) wide.
The study was funded in part by the Ontario Geological Survey and the Geological Survey of Canada.

Thundereggs are agate-filled nodules found in various parts of the Western United States. They range in size from 1/4 inch to as large as 5 feet in diameter. Generally, they are about the size of oranges. All are similar on the exterior, but no two are alike in pattern, design or color on the inside. The most colorful and beautiful of Thundereggs come from a small area in Jefferson County in Central Oregon (Pony Butte). In other localities they do not show such brilliant color and gem quality. In spite of their superior quality, only one in an average of twenty cut make outstanding specimens. These show vivid scenes of land and sea fantasies, which besides the bright hues, reveal the appearance of depth and dimension of distance. Cut and polished Thundereggs are beautiful to behold. They are one of the marvels of nature and are sought after and highly prized the world over.
According to legend, Thundereggs were so named by Native Americans of Central Oregon. The natives of this region are said to have believed these strange, agate-filled stones were missiles thrown by angry, fighting "Thunder Spirits" or "Gods" who dwelt on Mount Jefferson and nearby Mount Hood, two of the several snow-capped peaks high in the Cascade Range. The Native Americans thought when thunderstorms occurred these rival, jealous gods hurled large numbers of the round-shaped rocks at each other in furious anger. Thus, according to Native American legend, Thundereggs were scattered over the high plateaus of Central Oregon.
The unique agate-filled mud balls are found in layers of rhyolite lava flows, which spread over the land an estimated 60 million years ago. This was long before man appeared on the earth and thousands of centuries before the Cascade Mountain range was formed and pushed upward, due to tremendous stress beneath the surface of the planet. Geologists reason that the round-shaped Thundereggs were formed in gas pockets, serving as molds, that were left in the lava plows of the Eocene Geological Age. Over long periods of time, the gas cavities or cooled bubbles were gradually filled by water percolating through the porous rock formations, Water (hot or cold) oozing into the cavities carried rich quantities of silica (quartz). The solution lined, and in many cases filled, the cavity molds, first with the darker matrix material, then the inner core of agate or chalcedony. The beautiful and varying colors were derived from nearby minerals present in the soil. These processes are still going on, but at a much slower rate than during the times of volcanic action, with huge clouds and deposits of volcanic ash rich in silica (quartz).
Many geologists agree that the materials used by nature in forming these exquisite agate-filled Thundereggs came from the surrounding rhyolite lava frock in which they were formed. The matrix and the agate centers were made and composed by water carrying silica and minerals in solution. The water, by continuous action, robbed the rhyolite flows of its rich silica composition, causing it to eventually decompose. The harder more durable agate materials stayed in place.
This is very likely the origin of Thundereggs. Many await discovery in the now loose beds of decomposed rhyolite - to be dug, sawed and polished by the expert craftsperson, thereby revealing the hidden beauty of this remarkable "Wonder of Nature", the lasting enjoyment and adoration to all who are fortunate enough to view their splendor.
