President's
Corner
Dennis Gertenbach
Our programs for March
and April are
outstanding, with two
great speakers and two
great presentations.
In March, we have Ed
Raines talking about the
geology, mineralogy, and
mining history of the
Aspen district.
Waverly Persons will be
speaking at our April
meeting about
earthquakes and their
effects. He works
for the USGS Earthquake
Center in Golden and we
have all seen him on TV
every time there is a
major earthquake in the
world. Thanks to
Terry O'Donnell and Ray
Horton for arranging for
these outstanding
programs.
It is time to begin
planning our club field
trips for this year;
please consider leading
a field trip.
Paul Boni can help
you prepare for the
trip. Leading a trip
last summer was one of
the more enjoyable club
activities I did this
past year and I am
planning another this
summer.
See you at the March
meeting,

Club
Meeting
Thursday, March 10, 7:00
PM
West Boulder Senior
Center, 9th & Arapahoe
For our March meeting,
we are very fortunate to
have the renowned
mineralogist and mining
historian Ed Raines come
and talk to us on "The
Geology, Mineralogy, and
Mining History of the
Aspen District."
This is one not to be
missed!
And then coming up for
our April meeting (April
14), we will have
Waverly Persons of the
USGS talking about
earthquakes and the
effects of earthquakes.
Our annual silent
auction is tentatively
scheduled for the June
meeting.

Jr. Geologist Update
Dennis Gertenbach
Three Jr. Geologists
have completed the
requirements for their
Rocks and Minerals
badge. Andrew and
Joel Hyde and Stefan
Codrescu received their
badges at February's Jr.
Geologist meeting.
Congratulations to these
three young men.
Now the Jr. Geologists
are working on their
Lapidary Arts badge.
Paul Boni and Charlotte
Morrison are teaching
this badge. First,
the kids learned about
the different rocks that
can be used for lapidary
work and workshop
safety. Each
participant will choose
a project - perhaps
making a cab, rock
carving, or wire
wrapping - and complete
their project on
Wednesday nights at
Charlotte Morrison's
house. Instead of
having a Thursday night
meeting in March,
participants need to
arrange with
Paul Boni to set a
time to work on their
projects. If you
are interested in
working on this badge,
but were not at the
February meeting, please
contact
Dennis Gertenbach
for a time to review
shop safety and to
select your project.
The Jr. Geologist
program is open to all
families in the Flatiron
Minerals Club. Children
and youth meet monthly
to learn more about the
earth sciences and
rockhounding.
Participants can also
earn badges on a variety
of earth science
subjects. For more
information about the
program, please contact
Dennis Gertenbach.

Opal Discovery in
Wyoming
The Associated Press is
reporting the discovery
of a large opal deposit
in central Wyoming.
While most of the
specimens recovered thus
far are of the "common
opal" variety, there are
indications that
precious opal may also
be present. The precise
location of the deposit,
in a "desolate mountain
area" southeast of
Riverton in Fremont
County, was to be
announced on Friday,
March 5, by the Wyoming
State Geological Survey.

Gold Camp Road Project
Pete Modreski
The U. S. Forest
Service's is devising a
plan for reopening the
closed section of the
Gold Camp Road outside
Colorado Springs. Below
you will find the Forest
Service's announcement
soliciting comments, and
one such comment, from
Ray Berry.
Aside from being a
scenic drive and a "back
road" to Victor and
Cripple Creek, the Gold
Camp Road provides
access to a number of
popular or once-popular
mineral collecting
sites, including the
Eureka Tunnel (zircon
and other minerals),
Stove Mountain (smoky
quartz, zircon, topaz,
fluorite, hematite,
bastnaesite,
genthelvite), and the
St. Peters Dome area
generally (quartz,
microcline,
astrophyllite,
riebeckite, fluorite,
etc.). The section
of the Gold Camp Road
that provides access to
these areas has been
closed for some years
due to partial collapse
of one of the tunnels on
the road, necessitating
a several-miles walk now
to reach those sites.
The Forest Service has
offered several
alternative plans for
reopening the road,
particularly differing
in regard to whether
one-way or two-way
traffic is going to be
provided for on the
road.
Ray Berry (member of
Friends of Mineralogy
and of the Colorado
Springs Mineralogical
Soc.) has been
particularly involved in
keeping everyone updated
on the issues about
access to this road, and
below, I am reproducing
Ray's letter to the
Forest Service about
this. Ray is
concerned that although
re-opening the road will
be of considerable help
to mineral collectors,
those alternatives that
only provide for one-way
traffic, with very
limited areas designated
for parking, would mean
that collectors might
still have to walk
several miles to reach
many of the collecting
sites.
I invite those of you
who are interested to
read Ray's letter and
the material on the
USFS web page, and
communicate your own
comments to the Forest
Service if you so
desire.
Gold Camp Road (Forest
Service announcement)
The U. S. Forest Service
has a project to re-open
the presently closed
portion of the Gold Camp
Road near Colorado
Springs. Currently the
USFS is waiting to
receive comments from
the public on their
Draft Plan/Environmental
Impact Statement.
The final chosen plan
will influence mineral
collecting activities in
that area. If you wish
to make comments about
their plan, you must
send comments so that
they will be received at
the proper locations by
March 15, 2005.
For information about
the plan, please log on
to:
www.fs.fed.us/r2/psicc/pp/
and click on "Gold Camp
Road Issues." For
sending your comments,
go to the same website,
or mail them to Gold
Camp Road Project, c/o
Greystone, 5231 S.
Quebec St., Greenwood
Village, CO 80111, or
give them verbally to
Frank M. Landis,
District Recreation
Staff, 719-477-4203.
Ray's letter:
Dear Sirs,
I wish to comment on the
EIS plan for the Gold
Camp Road. I am a
resident of Colorado
Springs since 1970 and
have used the Gold Camp
Road innumerable times
during that period.
I am an amateur
mineralogist and, as
such, am a member of the
Colorado Springs
Mineralogical Society,
the Friends of
Mineralogy, and through
them, of the Rocky
Mountain Federation and
American Federation of
Mineralogical Societies.
As you know, the closed
section of the road
encompasses nearly all
of the old St Peters
Dome Mining District,
which has a great
attraction for
mineralogists, both
amateur and
professional, worldwide
because of the great
profusion of rare and
common minerals found
there.
Consequently, my
comments are swayed by
my concern for continued
collecting for myself
and for others.
First, my preferred plan
is Alternative G.
It is difficult for me
to see a difference in
the closed section of
the road, and that
portion which continues
all the way to Victor.
There are many narrow
one-way sections,
curves, drop-offs and a
tunnel in the presently
open section. I am
not aware of any major
problems with safety in
that section. There is
no more need to
"improve" the closed
section with guard
rails, berms and walls.
In fact, I believe doing
so is really a violation
of the spirit of the
National Historic Place
designation that the
closed section enjoys.
This trip should give
visitors the feeling of
traveling back in time
to the "Old days"
Exemption of this road
from the modern
standards of FS roads
should be made for this
reason. If it is
necessary to make such
improvements to bring it
into present FS Road
Standards, then it
should be done to the
whole Gold Camp Road.
If money is not
available for this, then
it should be opened, and
the "improvements" made
when funds are
available.
If Alternative E is
approved, then I think
there should be changes
made to the present plan
to accommodate better
use of the access.
I can understand a
desire of local
residents to restrict
stopping and parking
along the 3 mile section
from North Cheyenne
Canon Park to Fairview.
But restricting parking
to a couple of places
(Fairview and Tunnel 5)
is totally inadequate
when there are already
many pull-outs capable
of holding one or more
vehicles.
I have led several field
trips to the closed
section of the road by
permit from the FS, and
many of the collectors
are from outside the
local area, meaning they
want to visit several
places along the road.
The greatest demand is
to go to the Eureka
Tunnel prospect below
the road at Tunnel 5,
spending a morning there
and then continue to
Stove Mountain or
Fairview for the
afternoon. This
would be impossible to
do with one-way traffic
south, and certainly no
one would be willing to
go down to the city and
back up through North
Cheyenne Canon Park.
I believe two-way
traffic should be
allowed from Fairview to
the intersection with
Old Stage Road, even if
Alternative E is
approved.
Especially, with
alternative trails for
hikers and bikers to
avoid the road, there
really is no reason to
stick with one-way
traffic or to restrict
parking unduly along
this portion of the
road.
Over the years I have
seen many "flat-landers"
freeze when confronted
with driving on the Old
Stage Road. It is
very steep, narrow and
very crooked. To force
visitors to go DOWN this
road back to Colorado
Springs seems to be
"cruel and unusual
punishment"! The
transmissions of most
modern cars are
incapable of holding
back a vehicle on the
steep areas and brakes
sometimes fail.
I trust you will give
fair consideration to
these comments and come
up with an improved plan
that will allow the most
people to enjoy the
access with the least
possible restrictions.
Thank you for hearing my
plea.
Sincerely,
Raymond R. Berry

Field Trip Chair and
Secretary Still Needed
Paul
Boni
We're still looking to
fill two positions,
field trip chair and
secretary. Neither job
is difficult and both
are important to the
vitality of our club.
I've been the field trip
chair for two years,
program chair for two
years before that, and
fee it's time to let
someone else have a go
at it. Emily Epstein has
been our secretary for
several years but has
moved to Aurora. She has
continued as secretary,
commuting all that
distance, but honestly,
the commute is too much
for her.
Field trips are one of
the main attractions,
especially during the
summer months There
seems to be a pervasive
impression that the
field trip chair is
expected to lead the
majority, if not all, of
field trips. This is
simply not true. The
field trip chair
coordinates the field
trips. This includes
such simple tasks as
scheduling trips,
posting notices and
schedules of upcoming
trips in the newsletter,
filing liability
waivers, and soliciting
club members to lead
trips. Of course, you
can lead as many trips
as you like. Dennis
Gertenbach, Trick
Runions, Paul Boni, and
others have already
committed to leading one
or two trips each for
this coming summer. We
just need someone to
take responsibility for
coordination the effort.
One final point; There
is a big advantage in
being the field trip
chair. You often get to
go to the sites that YOU
want to collect. Think
about it, then contact
Paul
Boni
or
Dennis Gertenbach.
We'd love to have you on
board.

Turquoise
(CuAl6(PO4)4(OH)85H2O)
by Tom Prachar (from
PESA Rock News, November
2004)
Turquoise is a
secondary mineral
usually found in the
form of small veins and
stringers traversing
more or less decomposing
volcanic rocks in arid
regions. Turquoise is
valued chiefly for its
color and is an ancient
gem material. The oldest
mines are at Sarabit
Elk-hadem on the Sinai
Peninsula and date as
far back as 4000 B.C.
Nishapur, Iran is the
source of the finest
turquoise today just as
it has been since mining
began there over 2000
years ago. The only
other deposits of
importance today are in
China, Tibet, and in the
Southwestern United
States.
Turquoise came from many
localities in the
American Southwest, but
the most famous is in
the Los Cerillos
Mountains of New Mexico
where American Indians
may have begun mining as
early as 12000 years
ago. Indian jewelry set
with turquoise has
become very popular in
recent years. The result
has been not only a
large increase in price
but the use of
substitutes and the
manufacture of synthetic
turquoise. Natural
turquoise may be
impregnated with oil,
paraffin or plastic to
enhance its color and
increase its hardness.
These treatments can
usually be detected by
touching the material
with a red-hot needle.
An unaltered specimen
will not show any
evidence of melting.
Diagnostic Features:
Crystal habit:
Triclinic,cryptocrystalline
Specific Gravity: 2.6 to
2.8
Hardness: 6.0 (Moh's
scale)
Cleavage: good, rarely
seen
Luster: wax like
Color: blue, blue-green,
green
Streak: white

Sand Calcite Crystals
by Steven W. Veatch and
Ed
Raines (from PICK &
PACK, 11/2004)
Large quantities of sand
calcite crystals have
been found at the Snake
Butte locality in South
Dakota. Snake Butte is
situated on the Pine
Ridge Indian Reservation
approximately 23 miles
(35km) south of town of
Interior, South Dakota,
about 80 miles (130 km)
east of Rapid City.
Generally, the
collecting method is to
simply dig the sand
crystals out of loose
sand.
These interesting
specimens are thought to
have been formed by the
action of ground water
or by spring deposition
and are composed of
Calcite (CaCO3) and
coarse windblown sand
from an ancient dune
deposit field. The
absence of mud and silt
and the well-rounded
sand grains, along with
wind etched surfaces,
indicates dune origin.
The crystals are
composed of about 37%
calcite and the rest is
mainly sand inclusions.
The sand is composed of
quartz, orthoclase,
microcline, albite,
muscovite, biotite,
hornblende, augite,
tourmaline, zircon,
garnet, staurolite, and
magnetite (Wanless,
1922). Additionally,
volcanic ash, fragments
of volcanic glass, and
schist can be found.
Some of the minerals
present in the sand are
from Precambrian
pegmatites (tourmaline)
and schists (garnet,
staurolite, and schist
fragments) of the Black
Hills (Warless, 1922).
The process forming
these sand calcite
crystals is likely a
fluctuating water source
that floods the
unconsolidated sand on
an annual basis. That
water comes from a
source that provides
calcium carbonate in
solution. This mechanism
could be as simple as
groundwater, natural
springs, or a
combination of snowmelt
and/or spring rains
flowing on and through
limestone that then
flows into the
unconsolidated sand
exposure.This process
fills the pore space
within the sand
completely with water
that is close to being
saturated with calcium
carbonate, having
dissolved it at a
relatively low
temperature (taking
advantage of the
carbonates inverse
solubility with respect
to heat).
Then, as summer comes,
solar energy heats the
pore water while also
causing some
evaporation.
Concentration of calcium
carbonate follows and
the pore water becomes
super saturated. The
surface tension of water
would hold pores full of
solution on some areas
instead of allowing a
partial emptying of
pores. Also, the
permeability factor is
an important part of the
mechanism of sand
calcite crystal
formation. High
permeability would allow
the pore water to easily
flow through an
unconsolidated and very
loosely compacted sand.
Once the well-sorted
sand is saturated with
water, subsequent
evaporation will - at
one point- set off
precipitation.
Since there are many
nucleation sites
available around the
sand grains,
crystallization may
proceed rapidly, and as
it proceeds it will do
so with many growths in
parallel orientations.
With calcite there are
several chances of
forming orientations
that will lead to a
single crystal. When
chance creates a
different orientation an
intergrowth results, and
through time-as the
crystals grow
outward-those
orientations really
begin to come into play
so that intergrowths of
interlocked crystals
occur. The process stops
for each crystal group
when the water pockets
run out. Then the
process can begin again
next year. This is
likely a rapid
process-hours rather
than days, or at maximum
a few days.
Today, the Snake Butte
calcite sand crystal
locality in South Dakota
is a National Natural
Landmark and is managed
by Oglala Sioux Parks
and Recreation
Authority.

Large Emerald Found
(from The Rockhounder,
Montgomery Co. MD)
According to an article
in Mining Engineering
(January, 2004), what is
believed to be the
largest emerald found in
North America was
unearthed in Hiddenite,
NC late in 2003.
Weighing 1,861.9 carats,
the crystal was found on
property owned by the
North America Emerald
Mines (NAEM) Company.
The cavity in which the
emerald was found also
contained crystals of
quartz, pyrite,
muscovite, rutile,
calcite and other
minerals.
James K. Hill, president
of NAEM, said this
crystal was larger than
the one previously
considered the largest.
At 1,686 carats, that
emerald was uncovered on
the same property in the
1980's before NAEM
acquired it. On the same
day that the
1,861.9-carat crystal
was found, 3 matched
pieces of a high quality
emerald were also found.
The pieces, weighing
about 1,300, 100, and
400 carats indicate that
emerald weighed
approximately 1,800
carats.
The cavity, at least
5'x12', has not been
fully uncovered and its
depth is still unknown.
This find was about a
foot inside the
entrance. In 1999, Hill
found more than 3,000
carats of emeralds in a
cavern smaller than the
one recently uncovered.
The largest stone, known
as the Empress Caroline,
from that discovery
weighed 858 carats.
Another stone, weighing
71 carats, yielded two
finished gems. The
Carolina Prince, 7.85
carats, sold for
$500,000 and the
Carolina Queen (18.8
carats) is currently for
sale for $1 million.

Malachite
(from The Ammonite,
5/03)
Malachite is one of our
outstanding gemstones in
color. However, great
care must be exercised
in working with it, as
it is poisonous in raw
state. Never lick
malachite to see the
color. If you wet your
finger to apply it to
the stone, do not put
your finger back in your
mouth for the second
wetting. Grind it wet or
wear a mask when
grinding it dry and
polishing. When cutting
it on the saw, do not
get the contaminated oil
on your skin. If you do,
cleanse the skin
immediately.
If you smoke, you can
tell very easily if you
are getting malachite
dust because your smoke
will be sickeningly
sweet. The reason for
this sweet taste is
copper oxide dust mixed
with the moisture in the
mouth, and this
combination reacts on
tar of the tobacco,
turning it into
saccharin, an artificial
sweetener.

Cave Ratings
(from Rocky Trails,
Golden Spike News,
Strata Gem 4/91 via
Pueblo Rockhounds Chips
from the Rock Pile Jan
2005)
One rating of caves is
the depth. The deepest
is in the U.S.S.R. at
4,397 feet. The next is
only seven feet less, in
Spain. The third deepest
is in Mexico at 4,067
feet.
Another rating is the
length of known
corridors. The longest
corridor by a
considerable margin is
in Mammoth Cave Kentucky
with 236 miles. The
second longest is in
Switzerland with 87
miles. The third is
Jewel Cave in South
Dakota with 67 miles,
and fourth is Greenbrier
Organ in West Virginia.
Carlsbad Cavern in New
Mexico claims the
largest volume of
interior space. One of
its chambers has a
perimeter of 14 acres.
The ceiling height at
one place is 307 feet
above the floor
