President's
Corner
Evan D.
Elliott
The
April meeting with Jeff "The Knapper" as our program was a good one.
Thank you Jeff. I heard that the pursuit was continued successfully at
Charlotte's on the following Wednesday, complete with brownies. Remember,
folks, that Charlotte Morrison is very generous in making her home workshop available
to those of us who care to give her a call and let her know you would like to
use the equipment that is at her home in south Boulder.
Any
number of our club members are willing to meet and instruct other members in
any of the jewelry and/or lapidary arts. Myself included. Just give a call to
inquire further.
The
most important thing in all shop work is safety. And of course on field trips
safety comes first again. This months newsletter is centered on safety. Even if
your 're like me and have moments when you think you may "know it
all," for yourself and the rest of us, give it a good once over. I for one
can always use some reminders about safety. Thank you to all of you who make
our newsletter something to look forward to each month. Good hunting.
****************
May
Program
Place: Senior Center, 9th and Arapahoe,Boulder, CO
Time: Thursday, May 9, 2002, 7:15 PM
Program:
Hugh Tanner, one of our own, will present a slide show on Sharks teeth and other
fossils from Florida. Hugh took a little trip, had a great time, and is itchin'
to share with us. See you there! Note:
Many of the programs we bring to the club each month are the result of
suggestions and club members wanting to share their joy. If anyone has a
request for a particular topic, a suggestion for a specific speaker, or would
like to share from personal experience, feel free to speak with me (Paul Boni)
at the meeting or call me.
****************
Colorado's
New State Mineral
With
Colorado's mining legacy, it is hard to believe that our state did not have a
state mineral until this month. Governor Bill Owens signed a bill on April 17
that makes rhodochrosite the official state mineral of Colorado. Most major
mineral museums around the world have rhodochrosite from Colorado, and it is an
appropriate mineral to represent our state.
****************
Field
Trips
Mary
Golden
Speaking of Rhodochrosite, the next
field trip will be to the Sweet Home Mine on June 18. Unfortunately, only a
small number of people will be admitted and, due to demand, groups such as the
Club are allowed entry only once every year or two. Because of the number of
people likely to want to attend, I have asked that we be permitted two trips,
but have not had a response to this request yet. A lottery will be held at the
May meeting for available places. Further details will be provided at the May
and June meetings, as well as in the June newsletter. Please contact Mary
Golden for further information. Suggestions for future field trips and
volunteer
trip guides are welcome. See page 10 for May field

Notes From the
Board Meeting, April 8, 2002
Emily Epstein
Alex
Cook raised the question of scholarship funding. Interest rates have been so low
that putting grab bag and other earmarked proceeds into the endowment fund can
leave a shortfall. Discussion ensued. Paul Ralston suggested setting a
threshold: if accumulated interest available for scholarships is less than $500
by September 1, grab bag funds will go into the disbursable account to make up
the difference. The board approved this procedure.
There
was lengthy discussion of a possible children's program. Some members felt that
separate activities are not necessary. Dennis Gertenbach said he would consult
with parents on this.
Melinda
Thompson presented membeship applications for new members and the board
approved them unanimously.
Alex
Cook reported that the silent auction in March made a modest profit.
The
Senior Center has not been allowing us to enter the room before 7 p.m., so the
official start of club meetings will move to 7:15.
Gerry
Naugle reported on the exhibit proposal he submitted last month. Insurance
rates seem prohibitive. The issue was tabled until the May meeting, and he will
look further into possible venues for a display. The board thanked Gerry for
doing this.

It's A BIG
Stone!
Jon
Spunaugle,
AFMS Scholarship Foundation (April
AFMS newsletter)
Weighing
almost 6,000 carats, the "Dare Devil" really is a big faceted stone.
When you hold it in the light and turn it ever so slightly, it flashes a
brilliant variety of colors - salmon, lilac, yellow, red... Cut by the Dare
Devil Faceters, members of the Intermountain Faceters Guild, the stone has been
donated to the Scholarship Foundation and we are offering you a chance to own
it. It's a salmon colored cubic zirconia and it really is an impressive item.
It's been valued at several thousand dollars.
By
purchasing a ticket, or several tickets, you might just be the lucky person to
take the Dare Devil home with you. Tickets are $5 each or 5 for $20. They may
be obtained at one of the upcoming Regional Federation shows (Rocky Mountain,
Eastern, California or Northwest/AFMS) or by sending your check, payable to
AFMS Scholarship Foundation to: Jon Spunaugle, 1000 SE 144th Ct., Vancouver, WA
98868-70333.
Please
include a stamped, self addressed envelope with your ticket order along with
your name, address and phone number, so that the receipts may be returned to
you. The drawing to determine the lucky winner will be held at the NFMS/AFMS
Convention in Port Townsend this July. You need not be present to win. The AFMS
Scholarship Foundation needs our support now more than ever and this is one way
in which you can show that support...and perhaps own a fantastic faceted gem.
****************
New
in the Library
Dennis Gertenbach
Three
new books have been donated to our library.
Fire Into Ice, by Charles Fipke and The Great Diamond
Hunt by Vernon Frolick tells the story of the mining exploration geologist
that found northern Canada's vast diamond fields. Throughout his life he
searched the world for minerals from jungles to savannahs to the Arctic tundra
-- the Indiana Jones of mineral exploration.
Also
in the library are two books to help in mineral identification. Mineralogy:
Concepts, Descriptions, Determinations by L.G. Berry and
Brian Mason and Mineral Recognition by Iris Vanders and Paul F. Kerr
will help you identify that mystery mineral you collected this spring. These
books and other selections will be available at the next club meeting. If you
are looking for a book of special interest, contact Dennis Gertenbach to find out
what we have.
****************
International
Relations
Jack Nelson,
nelsonja@eros.com
Trading
with other rock, mineral, gem and fossil collectors and micromounters in other parts
of the world can be a wonderful experience. You can meet and learn about new
friends and their interests while enhancing your collections. You can also have
the satisfaction of sharing some of your good specimens with others.
Through
a friend, I learned in 1999 of a micromineral collector in Australia who has
turned out to be a good friend and frequent exchanger of terrific micromineral
specimens. For example, he sent me a specimen of ulrichite, a beautiful, tiny
acicular green mineral (calcium copper uranium hydrate phosphate). It was found
in only one known locality in the world, which is now depleted of that mineral
(Lake Boga Granite Quarry in Victoria, Australia). We exchange news,
information and specimens.
E-mail
has made the whole international community neighbors. I happily count a dozen
friends in other countries with whom I have exchanged specimens and with whom I
also frequently talk. I met all of my foreign and many US friends through
membership in a number of Internet interest groups focused on minerals, micromounting and fossils. They have nearly
2,000 members. There are many such groups to choose from). What a wonderful way
to promote good relationships, despite some of the difficult political barriers
that exist in the world.
Below
are some useful websites you can explore. Next month I will give you a further
list of good Internet sites or discussion groups.

Directory of Rock & Mineral Associations

great resource!)

Denver Gem &
Mineral Show Mini Report April 2, 2002
Judy Knoshaug, Secretary pro tem
Publicity
about the Denver Gem & Mineral Show is very important in getting the
general public to attend the show. Of course, most people who come to the show
enjoy it so much that they continue to come year after year. The Show Committee
works on new ideas for publicity every year and welcomes your suggestions. If
you have a novel approach to publicity or need flyers or posters to advertise
the show, please contact Regina Aumente at 303-978-9926.
There
are two events for publicizing the show for which your help is needed.
Discovery Day at Dinosaur Ridge is on August 3rd. A few people are needed to
talk to visitors and hand out flyers and free rocks. We will also have a booth
at the Taste of Colorado over the Labor Day weekend. Again volunteers are
needed to talk to visitors and hand out flyers and free rocks. The time slots
are two shifts from 11 a.m. to 3 p.m. and from 3 p.m. to 7 p.m. per day from
Friday through Monday. The booth will be in a covered tent providing shade.
Both of these are quite fun events, especially the talking to adults and kids.
So if you can help, call Regina. WE REALLY REALLY NEED YOU AND YOU AND YOU!
Don't
forget to pass out flyers and interest your friends and relatives in the show.
Your enthusiasm about the show is contagious!!
We
still need someone interested in learning to make the show ribbons. For more
information, call: Bill Basbagill at 303-986-5812.
Please
keep signing up volunteers to help out at the show. Don't forget some of the
club forms are due back by June 30th. The show will be here before you know it!

Legislative
Report, etc.
Dick Rodenburg
Earlier
this year, I reported that a team of federal Fish and Wildlife, US Forest
Service and Washington state biologists sent fur samples from a captive
Canadian lynx and a bobcat pelt to a lab for DNA testing, claiming the samples
came from creatures living in the wilds of the Wenatchee and Gifford Pinchot
National Forests in Washington (not normally lynx habitat). Had the lab been
fooled, the biologists could possibly have made a case to curtail access to
these forests.Apparently believing that no good deed should go unrewarded,
managers at the Interior Department praised the Fish and Wildlife team members
for their work and gave them a cash award.
Interior
Department Inspector General Earl Devaney complained to Secretary Gale Norton
that the award was "an incredible display of bad judgment." Rep.
Scott McInnis, Chairman of the House Forest Subcommittee, held hearings on
the allegations in late February. Albuquerque
Journal North, undated, and Denver Post, March 7, 2002.
Washington.
A Bureau of Land Management (BLM) March 15 Federal Register notice
raised eyebrows by announcing a decision that, in theory, allows new mining on
900,000 acres south of the White River near Meeker, Colorado. Doris Chelius, a
BLM land-law examiner, said the action is simply a bookkeeping maneuver to make
it easier to swap and otherwise manage
small parcels. She said there are no minerals worth mining in the area and oil
and gas exploration is presently allowed; no change in activity is expected.
The 900,000 acres includes Big Ridge in Rio Blanco County and the Grand Hogback
and Roam Plateau in Garfield County. Both of these areas are proposed as
wilderness in a bill drafted by Rep. Diana DeGette, D-Denver. Rocky
Mountain News, March 16, 2002.
DeGette
is also expanding the amount of new federal wilderness she has proposed from
1.35 to 1.6 million acres by adding 11 areas to the unsuccessful legislation
she first offered in 2000. The new areas are in response to calls from the
Colorado wilderness Network to designate elevation ecosystems below 9000 feet
for wilderness protection. Colorado now has about 3 million acres of
wilderness. Colorado Counties, Inc., representing county commissioners across
the state, supports preserving only about 200,000 additional acres. Denver
Post, March 22, 2002.
HR
4078, the Abandoned Hardrock Mines Reclamation Act proposed by US Rep. Mark
Udall, D-Boulder, would encourage citizens groups and state and tribal
governments to clean up abandoned mine sites that are polluting streams and
groundwater. The legislation would greatly reduce the liability such groups now
incur if they do any work to clean up an abandoned site. Denver
Post, April 13, 2002.
ALAA
warns readers about the dangers of HR 2974, the Paleontological Resources
Preservation Act. That act, if passed, would prohibit amateurs (read
rockhounds) from collecting on public lands unless accompanied by someone
associated with a museum or university. ALAA says the bill (1) perpetuates the
lie that all vertebrate fossils are rare; (2) imposes harsh penalties for
violations; (3) contains a false-labeling provision so broadly worded as to
make crimes out of mistakes; and (4) prohibits sales of legally collected
fossils. Marion Zenker, ALAA Legislative Coordinator, advised on April 18 that
Representatives from all across the country are being targeted with an intense
letter-writing campaign urging them to sign on to HR 2974. Read it for yourself at http://thomas.loc.gov.
Pull up the House bills, scroll down and enter 2974. Every club needs to
respond to their legislators on this one, ALAA says

Are
You Sure It's Jade?
From
Rock Chips,Vol. 33, No. 9,
October2000, published bythe Deming Gem &Mineral society, Inc.
1)
If a chip is knocked off the end of the rock, the freshly broken surface should
not sparkle in the sun. If it does, it isn't jade.
2)
If you can scratch it with a knifepoint, it
isn't jade.
3)
It should be much heavier than common rock of similar size.
4) Tap specimen lightly with a hammer. If
a moon-shaped fracture appears, it is agate or jasper, but not jade.
5)
If it is jade, it will have a smooth, waxy, almost greasy look.
6)
The only positive test for jade is x-ray analysis and specific gravity tests.
****************

I will support the rockhound project,
Help Eliminate Litter, Please (HELP), and will leave all collecting areas
devoid of litter, regardless of how found.
I
will cooperate with field-trip leaders and those in authority in all collecting
areas.
I will report to my club or federation officers,
Bureau of Land Management or other authorities, any deposit of petrified wood
or other materials on public lands that should be protected for the enjoyment
of future generations and for public educational and scientific purposes.
I
will appreciate and protect our heritage of natural resources.
I will observe the Golden Rule, exercise
good outdoor manners and at all times conduct myself in a manner that will add
to the stature and public image of
rockhounds everywhere.

Help
& How To Say It!
Omer & Valdene Goeden, From
CFMS newsletter, November 1986 via Amador Nugget, January, 2001, Everybody
Needs a Whistle
One
of the simplest and most effective signals is the use of a mirror. Search
pilots have seen a mirror flash over 20 miles away. Ground to air signals can
be constructed from contrasting color fabric panels, stomped snow or gouged out
dirt. The important aspect in signaling of any kind is to make the signal
appear to contrast or look out of the ordinary to searchers. Once an aircraft
or ground team sees you, the hand or body signals can be utilized to convey
specific messages.
Search And Rescue Symbols
These signals should be done as large as possible, 2-3 feet wide
and 6-12 feet long, using colors that contrast to the background if possible.
Some of these signals are for use by survivors and ground teams to communicate
with the aircraft.
1.
Lay out symbols by using strips of fabric, pieces of weed,
stones, etc.
2. Provide as much color contrast as
possible between the material used, and background.
3.
Symbols should be at least 10 feet high or larger.
4. Use additional signals such as flares,
radio, etc. to attract attention.
5. When
ground is covered with snow, signals may be made by dragging, shoveling, or
tramping the snow. The depressed area appears darker from the air.
6.
The pilot should acknowledge the message by rocking wings
side to side.
Symbols
