President's
Corner
Dennis Gertenbach
With summer
here, the Flatirons
Mineral Club swings into
action. Paul Boni
and his crew have a
field trip just about
every other weekend this
summer. The
monthly programs on the
second Thursday continue
in June and July.
The annual picnic will
be in August, plus the
Jr. Geologists will be
meeting each month.
Be sure to check out all
of these great programs
in this newsletter.
Happy
collecting to everyone,
and bring those special
finds to the towel show
this fall.
The June
board meeting will be
held on Monday, June 7,
at Alex Cook's residence
in Boulder.
****************
June
Club Meeting - Thursday,
June 10
This
month’s program will be
a presentation by
William Atkinson, of the
CU Geology Department,
on the use of blowpipes
in the analysis of
mineral specimens.
This is a technique
anyone can use with
simple equipment to
apply the “flame test”
to help determine the
species of a mineral
specimen.
****************
Jr.
Geologists - Thursday,
June 17
Do you
know how to tell a
fossil brachiopod from a
clam? Or an
ancient snail from an
ammonite? The Jr.
Geologists learned how
during May’s program.
In June,
the Jr. Geologists will
learn about reading
topographical and
geological maps.
The meeting will be at 7
p.m. on Thursday, June
17. Contact Dennis
Gertenbach at
gertenbach1@worldnet.att.net
or for more details.

Field Trips
Paul Boni
Kammerzell's Gold Claim, Central City CO
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, 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.

residents on a number of days throughout the year.
Remaining dates for 2004 are: Sunday, August 29, Wednesday, September 8, Wednesday, November 3, and Sunday, December 12. Free admission
applies to the museum only—IMAX & the Planetarium will still charge.
****************
Online Mineral Database
Here is an excellent online database of minerals and mineralogy that some of us have been using lately--it's got lots of info on many topics--check it out:
http://www.mindat.org
****************
Gold Dust
Extractor
Gerry Naugle
There is
a brand new type of
water-vortex extractor
at
Charlotte's
house for use by BVSD
teachers, students and
our FMC members [joint
project].
Club members expressed a
lot of interest in this
device when it was
demonstrated at the May
club meeting. If you go
gold panning this summer
and keep your black-sand
after your panning, you
can screen it and then
extract the fine
flour-gold out of it
easily at Charlotte's on
a Wednesday evening or a
weekend evening (call
ahead). Extractor
is indoors, away from
mosquitoes.
Gerry
Naugle has instructions
on the "tips &
techniques" of getting
the super-fine material
out of black and tan
sand, and the club has a
few new 'sniffer
bottles' available for
anyone who needs one
(which is nearly
required: $2.50) when
working with this super
fine material.
Note: Black sand
donations gladly
accepted ...the club
general treasury gets
50% and the FMC
scholarship fund gets
50% of any of the
proceeds from those
activities.
****************
Flatirons Mineral Club Fall Show Report
Alex Cook, Show Chairman
Plans are
well under way for the
annual Flatirons Mineral
Club Show which will be
held at the Boulder Elks
Lodge November 19-21.
Enthusiasm is running at
a high level among the
members of the committee
charged with running the
show ever since they
started meeting early
this year. At the May
meeting John Hurst,
dealer chairman,
announced that he has
already signed up nine
dealers, which is the
number for which we have
room. Anyone else who
applies will be on a
waiting list. This year
it was decided to place
dealers only in the main
ball room, leaving the
club room for displays
and various activities
such as seminars and
classes of various
kinds. John has already
laid out a floor plan
with the assistance of
Hallie Cook. A
dark room will still be
available for displays
and demonstrations of
fluorescent minerals.
This
year once again we hope
to have several
demonstrations of
activities such as
faceting, gold panning
and wire wrapping, among
other things. If you
would like to make up a
display case, be sure to
contact Paul Ralston as
soon as possible,
because he has only a
limited number of cases
available and they will
be assigned on a first
come first served basis.
Shirley Mehta is in
charge of ticket sales,
but we need someone to
back her up in this
capacity, so volunteers
would be appreciated. We
expect to have some very
nice door prizes, and
although we have quite a
few items available, we
are always happy to
accept donations from
our club members or
dealers to augment our
supply. We look forward
to Carol Codrescu
working once again as
our youth chair. We had
a lot of activities
aimed at children last
year, including the
fishpond, wheel of
fortune and sand pile,
and hope to have more
this year. Emily Epstein
has been very active in
providing publicity for
the show, both in
publications and on the
web. We have fliers
available and would
appreciate anyone who
would be kind enough to
distribute them wherever
possible.
The next
meeting of the mineral
show committee will be
at Charlotte Morrison’s
house Tuesday, July 13
and will be devoted
mainly to preparing
signs under the guidance
of experienced
sign-master Gerry Naugle.
Gerry has promised that
this year’s signs will
be firmly anchored so as
not to repeat the sad
saga of the loss of our
“old prospector” sign
which we think is
somewhere in Kansas
after last year’s
windstorm.
In the
meantime, we would like
to emphasize that this
show is a club affair
and there is no reason
why every one of us
should not pitch in and
help. Last year’s show
was a resounding success
because everyone was
there to assist. If you
would like to work on
the committee, please
come to the meetings and
we will be glad to give
you a job.

Geodes for Sale
Flatirons Mineral Club Members:
My wife and I owned the House of Art store in Gunnison for 25 years. When we retired we ended up with a supply of whole geodes that we had
purchased over the years. They are mostly from Chihuahua, Mexico. There are 1600 pounds of hollows from 3" to 8" with a few larger. 1300 pounds
of solids 4-5''. We used for bookends mostly. 700 pounds popper 3" and under and 640 pounds of red skins 4-8" mostly used for bookends. We also

Minutes of the Board
Meeting, May 10,
2004
Emily Epstein, Secretary
Present:
Paul Boni, Alex Cook,
Emily Epstein, Dennis
Gertenbach, Ray Gilbert,
Ray Horton, Gerry Naugle,
Terry O’Donnell, Trick
Runions, Melinda
Thompson, Lew Yoder
Paul Boni
reported that he is
still working to line up
field trips. Ray Horton
is still trying to
arrange a trip to
Caribou, and it is still
uncertain whether we
will be able to go to
Stoneham this year.
Emily
Epstein asked about
upcoming meetings.
In deference to members’
worries about West Nile,
the July meeting will be
at the Senior Center
rather than in the park.
Ray will check with the
senior center about the
use of a torch—she may
have to demonstrate on
the patio. Emily will
update the website, get
the word out, and notify
the speaker. If we have
to have the lampworking
part of the presentation
outside, we’ll have
mosquito repellant on
hand. The August picnic
will still be in the
park. September’s
program will be a
presentation on
micromounts by Bill
Harrison. November is
our annual towel show
and December is the
holiday party, leaving
only October
unscheduled. Various
board members suggested
possible programs. Gerry
Naugle presented the
treasurer's report. The
Club is still solvent.
Two-thirds of the dealer
spaces for the show have
been reserved and paid
for. There was a brief
discussion of badges.
The decision made at in
March stands—we will not
order special blanks,
but purchase badges in
batches in June and
December. Having gone
over the books, the
income from the silent
auction, and the
projected income from
the show, Gerry sees no
need to raise dues this
year. The rest of the
board agreed.
Dennis
Gertenbach and Melinda
Thompson have been
working on new member
packets. Trick Runions
will compile a list of
items to be included.
Board members should
send ideas to him.
Paul Boni
reported that there are
no new developments in
the North Table
Mountain situation. He recommends keeping track of it through Bob
Loeffler’s website.
Emily will add a link to
the club’s website.
Dennis
reported that the next
Junior Geologists’
meeting will be May 27th
at his house. The theme
will be fossil
identification. The
April meeting, on
crystal growing, went
well, and a good time
was had by all.
Charlotte Morrison spoke
on crystal
identification. The
program is going well.
Children are encouraged
to bring their parents.
FMC is one of the few
rock clubs in the area
with special programming
for children. Dennis and
his wife will be moving
to Lakewood, so we need
to find a new place to
hold it.
Since the
Gertenbachs are moving,
we also need someone to
take over the library.
Ray Gilbert volunteered.
Dennis has been working
on a list of titles in
the library, which he
hopes to finish before
moving. When it is
complete, it will be
added to the club’s
website.
Dennis
reminded the board that
the Denver Show is
coming. People need to
sign up to volunteer at
the show and at the club
table. Charlotte
Morrison will be the
contact person for the
club table. The board
also decided that we
should have a club case.
Dennis will fill out the
form to arrange it.
Dennis
has received an e-mail
from some people in
Ohio who will be vacationing in
Colorado
in July. He recommended
a book by Bob Dorrs.
Several other board
members receive similar
queries from time to
time. Discussion ensued.
Gerry
reminded the board that
we still need cloth bags
for grab bags. He then
went on to describe the
fine gold extractor that
he had recently bought.
He plans to make it
available to club
members and to teachers
and student in the
school district. If the
club can get funding, he
will sell it to the club
at cost. Gerry will
write a grant proposal
to the Denver Council.
Ray
Horton has 2 copies of
Taylor’s Guide to
Geology of Colorado. The
board voted to purchase
them from Ray at cost.
They will either be
given to program
speakers in lieu of
dinner, or sold at cost
to club members.
