President's Corner
Dennis Gertenbach
With summer on the way, it's time to get out into the field to search for those special specimens to add to our collections. Paul Boni and his crew have a 
great selection of field trips for us this summer.  Be sure to read his article about where we will be going, then mark your calendars and sign up with the trip 
leader. Just as a reminder, all field trip participants must be members of the club and each participant is required to sign a liability release for each trip.
 
You won't want to miss May's program. Our own Ray Gilbert will demonstrate the use of the "all you need machine."  Many have seen Ray's lapidary work 
and the jewelry he has made.  He will be sharing tips and suggestions. The meeting starts at 7:15 on Thursday, May 13th.  If you would like to further your 
lapidary skills, be sure to come to Charlotte Morrison's home on Wednesday evenings to use the club's equipment.
 
The May board meeting will be held on Monday, May 11 at Charlotte Morrison's house.

May Club Meeting - Thursday, May 13

We are fortunate to have our own club member and expert lapidarist Ray Gilbert for this month's program, who will give us a presentation and demonstration 
of the "All-You-Need" machine. The club owns two of these machines, which may be checked out for 6 months at a time. Ray currently has one of them 
checked out, so he will bring it with him and share with us what he has learned about using this device.

Field Trips!
Paul Boni
 
Here is the information you've been waiting for. The following schedule is a little light, but I expect to fill some gaps as the summer progresses. Here is the 
trip schedule, as it exists. Check your newsletter and the club's web page each month. I want to thank every one who has volunteered to lead a trip this 
summer. Your participation has greatly increased the number and quality of field trips. Thank you.
 
South Park Peridot
May 15
Trip leader; Emily Epstein
Peridot!!! 
 
Emily has, once again, gained permission for us to visit John Rhoads' peridot claim. If you have any doubt as to weather or not this trip is for you, ask Ray 
Gilbert to show you his gorgeous peridots. Bring a squirt bottle. 
 
Meet at 10 a.m. on the west side of the Salida Safeway parking lot (232 G St., left of the main entrance). If you need to get directions, there is a 
map on the website, or the store's phone number is 719-539-3513.
 
A spray bottle of water and a plastic bag to hold the peridot are highly recommended. Scratchers and kneepads might be useful, plus your usual field-trip 
gear (hat, gloves, specimen container, sunscreen, water, lunch, etc.) It will take about an hour to drive to the site. The last mile is fairly rugged, so SUVs 
are recommended, but passenger cars have made the trip.
 
John and Donna Rhoads are graciously allowing us to collect peridot on their claim. Cost is $5 per person. John will lead us to the site, which is an area at 
about 9,600 feet where peridot weathers out of basalt. Parking is on the deposit, so we can start finding peridot as soon as we step out the car. The area 
has been searched pretty carefully, so we may have to walk some distance to find nice material. Collecting is done by scanning the ground while walking, 
or getting down on all fours and looking for tiny bits of green peridot. If it hasn't rained recently, the peridot may have a brown film. Spraying water on likely 
patches of ground will let the green show through.  
 
 
Wamsutter, Kemmerer, and Farson Wyoming
May 29-30
Trip Leader; Paul Boni
Fossil gastropods (snails that is), Turitella agate, Fossil fish, petrified wood. 4-wheel drive recommended
 
Day 1: Travel to Wamsutter WY (approx. 4 hours), Eat lunch and spend an hour or two collecting turitella agate and loose turitella fossils. The ground is 
littered with collectibles. Just bring a sack or a bucket! Then we will travel to Kemmerer WY and set up camp. Last year we camped on BLM ground. It was 
lovely! Motels and RV campgrounds are available in town. Bring your camping gear and lots of water!
 
Day 2: We will spend the day at the Warfield Springs Quarry. The cost is $75.00 per person per day. If we have 10 or more participants, the price is reduced 
to $60.00 per person. The quarry provides a hammer and splitting chisel. The fossil fish are easy enough to find and abundant. The road to the quarry can be 
awful if muddy. Otherwise, any car will do. If it's muddy, a 4-wheel drive with good tires is required. We can arrange rides if needed. The quarry is hot and dry. 
Bring lots of water, sunscreen, and a hat. Also bring lots of newspaper or other wrapping materials to protect your treasure.
 
Day 3; Travel to Farson WY for Blue forest wood, travel home. Digging tools are needed. Those who do not have to get home right away may wish to stay, 
for another day or two, to collect fossilized wood in the area.
 
Kammerzell's Gold Claim, Central City CO
June 5 or June 12
Trip leader to be determined. Call Paul Boni for information.
Gold and small pyrite cubes
Vehicle; any
 
Our own Larry and Flo Kammerzell own a placer gold claim in the Central City area and have graciously agreed to allow us to pan for gold. The date is 
flexible to  allow for optimum water flow in the ephemeral stream. If the water is not flowing, we can't use the gold pans. A mine dump on the claim yields 
small pyrite cubes (< 1/4 "). Bring your own gold pan and a film can or other small container for your gold. If conditions allow we will try to have sluice and 
share the proceeds. Most of the gold found is "dust", but occasional pinhead sized nuggets are found.
 
Special precautions: The Central City area is literally undermined with old mine workings. Mine shafts and air vents can be anywhere and are never marked. 
They are usually fatal if one falls in. Participants will not be allowed to wander and children must be kept right next to parents. We cannot be flexible on this. 
As long as we remain by the streambed there is no problem.
 
Calumet Iron Mine
June 19 and 20(?)
Trip leader Bill Reid
 
The famous Calumet mine is a source of beautiful epidote. Also available are quartz crystals, uralite (actinolite pseudomorphs after diopside), magnetite, 
garnet, and small (but gemmy) sapphire. The hike to the mine is strenuous and not for the very young, old, or physically challenged. Good hiking boots, 
lots of water, eye protection, hard hats, and etc, will be required. The outing is strenuous enough that most people rarely want to do it a second day. Yet to 
be  determined: a possible second day at another, nearby site.
 
Creede CO
Trip leader; Paul Boni
July 3-5 ... 
Sow belly agate, quartz crystals, amethyst, pyrite, and etc...
 
This trip is still in the planning stages, but we are going. Please if you have information about the area call Paul Boni and help us plan.The Creede area is 
an old and famous mining district. Mine dumps often have amethyst, wire silver (not so often as we would like!), sow belly agate, and other goodies. Last 
year an operation opened up on one of the mine dumps as a fee dig. If I remember correctly, they were charging by the pound, whatever you collected. I 
don't have the fee at this time but am working on it. There are also sites nearby which yield quarts crystals,  agates, fossils, and other neat stuff. We will 
spend the long holiday weekend in the area and some can stay a couple extra days if they wish. Camping, motels, and RV parks are available.
 
The Contin-Tail show
August 12-15
Mt Antero (Aug 14)
Aquamarine, smoky quartz, microcline, topaz, phenakite.
Trip leader; Paul Boni
 
The Contin-Tail Show is one of the highlights of the year. If you have never been, you should try to make it. It is a rock and mineral show, similar to all the 
other shows one can attend ... except that is held out of doors and includes a lot of rockhounds who dig and sell their own stuff. It's a lot of fun, a gorgeous 
mountain setting, with everything a rockhound could want. The show is held at the Buena Vista rodeo grounds. Camping at the rodeo grounds is free and 
there are porta-potties in good numbers. Motels and restaurants are available in town and the Mt. Princeton Hot Springs is just down the road. Nearby 
collecting sites include Ruby Mountain, calumet iron mine, a brachiopod site south of Salida, and others.
 
Mt Antero: We will have a collecting trip up Mt. Antero on Saturday, Aug 14. Meet in front of the concession stand at the rodeo grounds at 7 am sharp. It's 
early but there is no other way. The weather can close in very quickly and afternoon thunderstorms are not to be ignored up there. Low range 4-wheel drive 
is required. The road is a moderate and technical 4-wheel drive road. If you have problems with altitude and narrow roads with steep drop-offs, this trip is not 
for you. Good hiking boots (absolutely no sneakers!), hardhats, eye protection, rain gear, proper clothing, jacket or parka, food and water are required. 
Children must stay with parents at all times. Participants must be in good physical condition.
 
 
McCoy, CO
Sept 11.
Trip leader; Dennis Gertenbach
Fossils; crinoids, brachiopods, gastropods, and others
 
This is a famous locality for the above-mentioned fossils. Crinoid stems can literally be found by the sack full. But you don't need that many anyway. The 
point is that this is a site where anybody and everybody can find fossils. Preservation quality of these fossils is very good and a few pieces belong in every 
collection. This  is a great trip for the kids! The site is usually hot. Lots of water, hat, and sunscreen are a good idea for this trip.
 
Trips unscheduled as of this writing.
 
The following are trips that will happen this summer, but have not yet been scheduled. We are working on other field trip ideas and will announce them when 
the details are worked out.
 
Lien Quarry
Trip Leader; Connie Hauser
Calcite Crystals.
 
The reason that this trip is yet unscheduled is that the quarry operators have not hit a seam of calcite crystals lately. The plan is that when they do, they 
will call Connie and Connie will call all who are interested. The field trip will then be on. Please leave your name and phone number with Connie if you are 
interested. Lien Quarry calcite crystals are often UV fluorescent.
Caribou Silver Mine
Trip Leader; Ray Horton
Ray has spoken with Tom Hendricks who has graciously agreed to allow us to pick over the mine dumps at the famous Caribou Mine. The main attraction 
here is the chance to find wire silver specimens. Other mine dumps attractions are always things like quartz and pyrite crystals and specimens of ore 
minerals. This is a beautiful site and well worth the trip, even if just for a pick nick lunch! At this time we do not have a firm date with Mr. Hendricks. Make 
sure you check out the June newsletter for further information.
Kremling, CO
Trip Leader; Bill Eeds
Fossil wood
Bill has found a site that yields a very nice petrified wood with a black interior and tan rind. For the lapidaries in the club, it takes a nice polish. For the wood 
collectors, this material shows good grain and knots. At this time we have not set a date for this trip.
Hans Peak, CO
Trip Leader; Melinda Thompson
Quartz Crystals
 This is a beautiful site, for the scenery alone! There is also buried treasure in the form of clustered quartz crystals. Anyone can find quartz here! The site is 
at timberline and there is a little bit of a steep narrow road. Low range 4-wheel drive is required. I'm sure we can arrange a ride to the top for those who do 
not have a proper vehicle. That, of course will depend on how many need a ride.

North Table Mountain Update
Paul Boni

Rockhounds turned out in good numbers at the meeting on March 30 with the Jefferson County Open Space board. At this point in time things look positive 
for the future of mineral (zeolites) collecting on North Table Mountain. It's likely that collecting will be restricted to selected sites and that special use 
permits will be required. But who can say what will transpire between now and the finished management plan?
 
The Open Space Planning Team had the following to say about mineral collecting: "Staff Believes that limited mineral collection could be compatible with 
other recreational uses on the park and with Open Space's resource protection objectives. To manage the activity, a Special Activity Permit would be 
required to allow Open Space to monitor this activity." Open Space Staff also recognize that "the mountain is a world renowned collection area, with 
collections dating back to the 1800's."
 
Jefferson County personnel have heard from many of us by email and telephone. This evening they met a good number of us personally. The atmosphere 
was very positive and I want to thank all attending rockhounds for making a good impression. There will likely be additional meetings in the future. However, 
at this time none are scheduled.
 
Participants were asked to comment in writing about any subject(s) of concern. A lot of those comments concerned interest in continued zeolite collecting! 
The open space board will tally those comments and gauge areas of interest before hosting another meeting. 
 
Several of us have asked to be placed on mailing lists so that we can keep ourselves informed on important developments and will disseminate information 
as it comes available. Nothing is certain yet.
 
Bob Loeffler of the North Jeffco Gem and Mineral Club has put together a fantastic web page for the purpose of disseminating and updating information 
about North Table Mountain and our efforts to keep mineral collecting available. Please visit his  site and send along your support. Thanks Bob! 
http://www.peaktopeak.com/njeffco/legislation/ntablemtn_openspace.php 
 
KEEP THOSE EMAILS ROLLING! If you haven't yet written to Mr. Frank Kunze at kunze@jeffco.us, please do so. It is not too late and the more letters 
they receive the stronger our message becomes; keep mineral collecting available on North Table Mountain (please).

Jr. Geologist Night

Last month was the first Jr. Geologist program for FMC kids and their parents. Four Jr. geologists - Addison Starn, Stefan Codrescu, Joel Hyde, and 
Andrew Hyde - learned how crystals formed and how to use crystals to identify minerals from Charlotte Morrison and Dennis Gertenbach.  Each participant 
took home three different solutions to grow crystals during the next couple of weeks, as well as several crystal mineral specimens to add to their 
collections. Reports several days afterwards were that the copper sulfate and alum crystals were growing great.
 
Next month's program will be on Fossil Identification. The participants, along with their parents, will learn how to identify invertebrate fossils (animals that do 
not have a backbone), including gastropods, bivalves, brachiopods, and echinoderms. The Jr. Geologist night will be at 7:00 p.m. on Thursday, May 27, at 
Dennis Gertenbach's house (5330 Lichen Place in Gunbarrel).  Please let Dennis know if you will be coming, so that we have enough supplies for everyone. 
And, bring that unidentified fossil and we will see if we can figure out what it is.

Colorado Science and Engineering Fair

The Flatirons Mineral Club gave Colorado mineral specimens to the top four finalists in the 49th annual Colorado Science and Engineering Fair this year, in 
the Geology and Earth Science Departments. They were:  1st place Senior Division, Rachel Doyle - 12th grade - Monte Vista High School, and 2nd place 
Senior went to Tyler Keck - 10th grade - Monte Vista High School.
 
In the Junior Division, the awards went to: 1st place, Daniel Neligh - 8th grade - from Ricks Center For Gifted Children of Denver, and the 2nd place winner 
was Channa Rotenberg - 8th grade - from Rocky Mountain Hebrew Academy of Denver.
 
There were many more competitors this year than in the past, and though they didn't all receive an award, everyone did quality work. Good Students!

Denver Gem and Mineral Show, Mini Report April 2004
Judy Knoshaug, Secretary
 
Keep those dates in mind  September 17, 18 and 19  for the fantastic 2004 Denver Gem and Mineral Show! The theme is ZEOLITES AND ASSOCIATED 
MINERALS. Have you started planning your exhibit? It is not too early to be thinking about exhibits for you personally or for your club.  There are many 
categories of possible exhibits, both competitive and non-competitive.  Perhaps you have collected at North Table Mountain in the past and have a nice 
collection of Zeolites that could be displayed. Or perhaps this is the year you have decided to try your hand at a competitive exhibit. The Show Committee 
would like to see more competitive exhibits. Then there is the Club Prospectors Trophy.  This will be the third year for this competition. So far only three 
clubs have participated in this competition. Lets try to increase that number. Winning the Club Prospectors Trophy would be a great achievement and 
may attract new members for your club.
 
 
The Show Committee is always looking for new people to join the committee to help plan and improve the show. There is an acute need for someone to help 
in the publicity area. Regina Aumente has been handling publicity for the show for many years and needs assistance. There must be some club members 
out there who have a little experience with publicity matters and who would enjoy working in this area for the show. Please come forward. WE NEED YOU!!  
If you are that special person, please dont be shy but call either Regina Aumente at 303-978-9926 or Barb Melby at 303-423-5876. Working on the show is 
fun and rewarding. You wont regret it.

Two New Dinosaurs Discovered in Antarctica 

The National Geographic News reported that fossil hunters have found two completely new species of dinosaur in Antarctica. This increases the number of 
dinosaur species found on the southern-most continent to eight. Exploration for dinosaur fossils in Antarctica is difficult, due the some of the harshest 
conditions on earth.
 
The first, found near the top of a 13,000-foot peak, was a 190 million-year-old plant-eating sauropod that lived during the early Jurassic period. A preliminary 
investigation suggests that this animal would have been 6 to 7 feet tall and 30 feet in length. Although quite small compared to other sauropods, such as 
brachiosaurs and Diplodocus which reached 100 feet in length, this may be the largest dinosaur ever found in Antarctica and perhaps the oldest.
 
A week later, the fossilized remains of another dinosaur were found. This 70-million-year-old dinosaur from the late Cretaceous period is the only known 
Antarctic meat-eater. This creature was found on the bottom of what was once an ancient sea, alongside the typical clams, ammonites, and other sea life 
found during this time. This dinosaur is estimated to have stood just 6 to 8 feet tall in life.
 
Although Antarctica is now covered in ice and snow throughout the year, this was not always so.  During the Cretaceous, it enjoyed a warmer, lusher 
climate, similar to that of the U.S. Pacific Northwest today.

Mega-Earthquake FAQ's
Pete Modreski, U.S. Geological Survey
 
For your information.. I've been asked to help let the public know that the USGS has prepared two new web pages with questions and factual answers about 
earthquakes and particularly  in regard to "megaquakes", which as you may know, is the subject of a made-for-TV movie, "10.5", that will be shown this 
Sunday and Monday.
 
The USGS is not in the business of publicizing the movie, which of course has the usual mixture of fact and sensational action (more of the latter, it would 
seem from what I've seen and heard), but we would like to make available accurate information about what earthquakes really do, what their hazards really 
are, and "how large an earthquake is possible to take place". The websites below contain some interesting reading, and links to additional earthquake info 
pages.  This should be of interest to educators, geologists, and everyone else who is exposed to more than the usual amount of publicity about earthquakes 
in the coming week or weeks.
