President’s
Corner
Evan D. Elliott
The season is here. Yes field trip season! Gabi Accatino and Anita Colin
have put together a great schedule of trips to choose from. Please look
further in this newsletter for the Field Trips Schedule. Be sure to sign up
or give the field trip leader notice of your intentions to attend a trip in
advance of its scheduled date (s). As a reminder it is always good to
review the AFMS Code of Ethics, found here, as a link from the RMFMS
web site.
Also, remember that summer time
is picnic time! Plan for our annual club picnic on Sat., Aug 18th, at the
North Boulder Park, main pavilion, approximately 300 yards NW of the corner
of 9th Street and Balsam Ave. Same time and place as last year (start at
11:00 a.m.).
I hope to see you all soon—Happy
Rock Hounding!

Spring Club Programs/Trips
Gabi Accatino,
Co-Chairperson, Programs
Our
May club meeting is our annual field trip announcement meeting/gala with a slide
show by Gabi and Anita and sign-up sheets for this summer’s field trips.
(Donna Ware, who was originally scheduled to present a short program on the
digital microscopes that she sells, will not be able to come.)
The
next field trip will be Saturday, May 12, a joint trip with the Colorado
Mineral Society to DIA to dig for plant fossils. Then, don’t forget our
“field trip” to man a booth at the Boulder Creek Festival, May 27-28
(Sunday, Monday). Sign-up for both of these exciting events at the May 10 meeting!
There
will be no club meetings in June, July, or August. In lieu of the June
Meeting, June 14, we will have a trip to pick rocks at John Hurst’s house,
from a large selection that he will make available to us. And of course, in
August we will have our annual club picnic as usual at the North Boulder
Park pavilion, August 18.

Jr. Geologists
Activities
Last
month the Junior Geologists continued to work on the Lapidary Arts badge,
plus began working on the new Maps badge. In May, we’ll continue to work on
both badges. Terry O’Donnell will work with each junior to make a cab and
then set it into a mount. Also, we will learn more about maps and map
reading. And we will go on monthly field trips this summer to collect
minerals, rocks, and fossils to add to our collections.
The
Jr. Geologists program is open to all Flatirons Mineral Club families. Each
month we learn more about geology, plus earn badges for different earth
science activities. For information about the Jr. Geologists program,
please contact Dennis Gertenbach.

Five More Badges
for the Jr. Geologists
The
American Federation of Mineralogical Societies (AFMS) sponsors the badge
program that the Jr. Geologists can earn. At each month’s Jr. Geologists
meeting we work on the requirements for one or more of these badges. This
spring the AFMS announced five new badges, bringing the total to 20. The
new badges include:
·
Reaching Across Generations – having the kids work in
partnership with older club members.
·
Fluorescent Minerals - learning to identify
fluorescent minerals and why they fluoresce.
·
The World in Miniature - learning about collecting,
cleaning, and trimming micromount and thumbnail minerals and/or fossils
·
Maps - learning about different types of
maps-geographic, geologic, topographic, roadmaps, etc., and how to use
them.
·
Special Effects -learning about rocks with special
properties and what causes those properties, such as magnetism, double
refraction, fluorescence, twins, and pseudomorphs.
The
AMFS badges that the Jr. Geologist can earn, including the newest five
badges.
Gavin Morrison
Earns the AMFS Rockhound Award
Juniors
who earn six of the AMFS badges can earn the AMFS-Future Rockhounds of
America award. Since the badge program began in 2004, nine Colorado juniors
have earned this award, all Jr. Geologists from the
Flatirons

Denver
Gem & Mineral Show Mini Report – “Cu in Denver”
Judy Knoshaug, Show Secretary
With
all the snow this February, it is difficult to remember that summer and the
fun collecting season is only a few short months away. Then summer is
followed by the Denver Gem & Mineral Show. What a great way to end the
summer with the most wonderful event in Denver for our hobby. Don’t forget
the dates, September 14 – 16, 2012, and the feature, Copper and Copper
Minerals.
Since
many persons enter the Best of Species competition at the show, here is
some information about this competition. The Best of Species competition is
open to any individual (amateur or professional), but not to institutions,
groups, clubs or businesses. An individual may enter only one specimen in
each size or type category. A trophy will be awarded to the best Species
entry in each of the 7 categories listed on the entry form, which are
thumbnail, miniature, cabinet, oversize cabinet, field collected, Best of
Colorado and lapidary/jewelry. Specimen quality will be judged on the basis
of established standards for Copper Mineral species. Workmanship for
lapidary/jewelry entries must be that of the exhibitor. Mineral species
with the Cu cation in the first or second position in the formula of the
mineral are eligible. Judging Chair, Larry Havens, expands on this
information as follows since the judging will be more difficult this year
due to the theme: “It is tricky judging this competition because, in each
size category, we are probably judging multiple species (i.e., apples and
oranges). Therefore, we look for specimens with good size for each category
– as close to a full inch for thumbnails, etc. - we consider the typical
material from the location a specimen is from, and ask how does this
example stack up – how free from damage is each specimen – if color or
clarity is an issue in determining quality for the specie, does the
specimen show that quality to advantage – rarity may set a specimen apart
from its mates in a size category, but the other criteria still play a role
(for instance, a translucent, damage-free, aesthetic azurite from Tsumeb
would probably get the nod over a rarer Arthurite, because the Arthurite
specimen will likely be a cluster of tiny crystals. The subjective criteria
of aesthetics and “the wow factor” play a role as well. That’s why we use
multiple judges, knowing full well that opinion will play a part in the
choices made.” So start thinking about entering this competition. Look over
your collection for that outstanding Copper mineral that just might win you
a trophy. Purchased specimens are eligible except in the “field collected”
category. Should you have any questions concerning the Best of Species
competition, please contact Larry Havens
at 303-757-6577.

North Table Mountain Field Trip
Saturday,
May 5th, was a beautiful day to hike up North Table Mountain outside of
Golden to collect zeolite minerals. Everyone came home with great specimens
of analcime, chabazite, and thompsonite. Some of the less common zeolite minerals found this year
was mesolite, fluorapophyllite, levyne, and gonnardite.
Seven
FMC members were joined by members from the Denver Guild, Colorado Springs,
and Lake George clubs. In all, 35 people had a great time, adding several new
minerals to their collections.

Unusual 'Sea Tulip' Creature Discovered: Lived in
the Ocean More Than 500 Million Years Ago
ScienceDaily
(Jan. 19, 2012) — A bizarre creature that lived in the ocean more than
500-million years ago has emerged from the famous Middle Cambrian Burgess
Shale in the Canadian Rockies.

Royal Ontario Museum)
Officially
named Siphusauctum gregarium, fossils reveal a tulip-shaped creature that
is about the length of a dinner knife (approximately 20 centimeters) and
has a unique filter feeding system.
Siphusauctum
has a long stem, with a calyx -- a bulbous cup-like structure -- near the
top that encloses an unusual filter feeding system and a gut. The animal is
thought to have fed by filtering particles from water actively pumped into
its calyx through small holes. The stem ends with a small disc which
anchored the animal to the seafloor. Siphusauctum lived in large clusters,
as indicated by slabs containing over 65 individual specimens.
Lorna
O'Brien, a PhD candidate in the Department of Ecology and Evolutionary
Biology at the University of Toronto and her supervisor, adjunct professor
Jean-Bernard Caron, curator of invertebrate paleontology at the Royal
Ontario Museum, reported on the discovery Jan. 18 in the online science
journal PLoS ONE. "Most interesting is that this feeding system
appears to be unique among animals. Recent advances have linked many
bizarre Burgess Shale animals as primitive members of many animal groups
that are found today, but Siphusauctum defies this trend. We do not know
where it fits in relation to other organisms," said lead author O'Brien.
"Our
description is based on more than 1,100 fossil specimens from a new Burgess
Shale locality that has been nicknamed the Tulip Beds," she added.
Located
in Yoho National Park, British Columbia, the Tulip Beds were first
discovered in 1983 by the Royal Ontario Museum. They are located high on
Mount Stephen, overlooking the town of Field. Like the rest of the Burgess
Shale, the beds represent rock layers with exceptional preservation of
mostly soft-bodied organisms.
The
Burgess Shale, protected under the larger Rocky Mountain Parks UNESCO World
Heritage site and managed by Parks Canada, preserves fossil evidence of
some of the earliest complex animals that lived in the oceans of our planet
nearly 505 million years ago. The discovery of Siphusauctum expands the
range of animal diversity that existed during this time period.
The
research was partially funded by UofT fellowships to O'Brien and a Natural
Sciences and Engineering Research Council of Canada Discovery Grant awarded
to Caron.

Fossils
in the News
Dennis
Gertenbach
Migrating
Dinosaurs
We
all know that many modern animals migrate as the seasons change. Birds fly
south for the winter, elk move to lower elevations when the snow covers the
high mountains, even monarch butterflies winter in Mexico. Did dinosaurs
also migrate when conditions change? Scientists now say that 150 million
years ago, North American sauropods may have migrated, too. A new study
suggests these enormous plant-eating animals, which included Apatosaurus,
Camarasaurus, and other long-necked dinosaurs, traveled as the seasons
change to find sufficient food throughout the year.
Henry
Fricke, a geologist from Colorado College in Colorado Springs, led a team
of scientists that studied the chemical composition of amarasaurus teeth
and the sediments that surrounded the fossil teeth. Specifically, they
compared oxygen isotopes in the dinosaur tooth enamel and the surrounding
rock. The relative amounts of different oxygen isotopes change at different
locations on earth. They found that the isotopes varied in different layers
within the dinosaur teeth. These layers corresponded to tooth growth over
short periods of time and the isotopes in the tooth layers only matched
those in the surrounded rock once per year. They interpreted this yearly
variation to show that the animals migrated like many modern animals.

Dinosaurs Feasted
on Birds
Jingmai
O’Connor and her colleagues at the Chinese Academy of Sciences in Beijing
have found a fossil dinosaur, named Microraptor gui, in northeastern China
that had unexpected fossil bones in its abdomen – bird bones. The fossil
feet and partial wing bones of a now-extinct, tree-perching bird were
swallowed whole by the dinosaur, its last meal. The researchers proposed
that this fossil find shows that Microraptor frequented trees and hunted
deftly enough to snag what was probably an adult bird. Other
paleontologists disagree, pointing out that modern cats catch tree-dwelling
birds mostly on the ground, which might have been the case with
Microraptor.

gui. Although Microraptor gui had wing-like feathers, it was a dinosaur.

A Jurassic
Cricket Love Song
Scientists
at the University of Bristol have recreated the love song of an extinct
cricket that lived 165 million years ago. Using microscopic wing features
on an exquisitely preserved fossil discovered in Northeast China, Chinese
paleontologists Jun-Jie Gu and Dong Ren teamed up with Fernando Montealegre-Zapata
and Daniel Robert from the University of Bristol and Michael Engel of the
University of Kansas to study what sounds this ancient bushcricket made.
Modern-day bushcrickets, also known as katydids, produce mating calls by
rubbing a row of teeth on one wing against a hard structure on the other
wing. By studying similar structures on the fossil of this ancient
bushcricket, named Archaboilus musicus, the scientists concluded that this
animal must have produced a single frequency musical song. As modern katydids
produce similar songs for mating, the scientists propose that ancient male
katydids used their song to attract lady katydids.
What
did these ancient animals sound like? Listen at http://www.bris.ac.uk/news/2012/8210.html.
New Theory about
the Evolution of Fish to Four-Legged Animals
Many
of us learned in school that fish evolved small limbs so they could escape
a drying pond, crawling to another pond with abundant water. However,
University of Oregon scientist Gregory J. Retallack has studied numerous
sites in Maryland, New York and Pennsylvania which suggest that a migrating
fish "probably could not have survived the overwhelming odds of
perishing in a trek to another shrinking pond." By studying
transitional fossils between fish and amphibians from the Devonian and
Carboniferous periods, Retallack has found that these transitional fossils
were not associated with drying ponds or deserts, but consistently were
found associated with humid woodland soils. He proposed that these fish
evolved limbs for negotiating woody obstacles and for feeding in shallow
water, the habitat found in humid, wooded floodplains.

Annual
Tour Showcases 1890's Anchoria-Leland Mine in the Cripple Creek and Victor
Mining District
This
will be the opportunity of a lifetime to visit the surface plant of the
Anchoria Leland Mine. There will be a fabulous opportunity to take pictures
of this historic mine that sits above the mining district. Reservations are
a must. Details follow:
There
will be a tour, as part of Memorial Day Weekend in Victor of the historic
Anchoria Leland Mine surface buildings. High above Cripple Creek the
Anchoria-Leland Mine is a landmark with a grand view of the mountains. The
mine, owned by the Anchoria-Leland Mining and Milling Company in 1892,
produced over $3 million worth of gold . The tour will showcase the 1890
mining operations on Gold Hill that made the Anchoria Leland one of the
great producers.
This
tour is exclusive to May 26 as the mine is located on Cripple Creek
&Victor Gold Mining (CC&V) property and is not accessible to the
public at any other time. This tour is of the surface structures only and
is sponsored by the Southern Teller County Focus Group (STCFG) and
CC&V. This special tour of the 1890's mine structures, including the
giant wooden headframe and hoist house, will include presentations by
Victor Miner Gary Horton and Mining Engineer Ed Hunter.
Please
arrive by 9 a.m. at the Victor Lowell Thomas Museum as you will be required
to sign in and view a safety video. Please feel free to arrive any time
between 8 and 9 a.m. and sign in early; if you get here early, you can
enjoy breakfast in Victor before the tour. The tour cost (donated to the
STCFG) is $10 per person. We will provide hard hats and safety glasses.
Please note that all tours that are not pre-paid by credit card will
require a cash-only payment at the museum the morning of the tour; no
credit cards will be accepted the day of the tour.
Online,
prepaid reservations may be made online at VictorColorado.com There is
limited seating on the tour vans and some carpooling will be required.
Reservations are requested and can be made by email to
stcfg@victorcolorado.com. Dress warmly and bring sunscreen, hat and
footwear suitable for walking over gravel and rocks. The Doyle Block in
downtown Victor will be open from 1-4 for tours. The 1899 building at 307
Victor Avenue is owned by the Bielz family and has a newly restored lower
storefront, thanks to a grant from the State Historic Fund of the olorado
Historical Society. The grant, sponsored for the Bielz family by the STCFG,
funded the installation of new large store windows, and the refurbishment
of the brass columns and wood panels on the exterior of the building. The
structure was built in 1899 by James Doyle, one of the owners of the famous
Portland Gold Mining Company. The interior of the building is much the same
as it was in the 1940s when the Silver Dollar Saloon was housed in one
half.
The
tours will be a featured part of the season opening of the Victor Lowell
Thomas Museum. The museum opens May 26 for the summer season and will again
this host gold and gem panning, modern mine tours, exhibits and special
events. Museum hours will be 9:30-5:30 daily Memorial Day weekend through
Labor Day and weekends in September and October weather permitting. Admission
is $6 per adult, $5 per senior, $4 per child; the admission includes one
hour of gold panning. Modern mine tours start May 27 and will be offered
every day but Thursdays through Labor Day at 10 a.m. and 1 p.m. Please make
reservations online at VictorColorado.com or leave your information at
719-689-4211 and a tour staff person will return your call. For more

Free Rocks
To
FMC club members:
I
have a small wheelbarrow full of rock slices, small slabs and miscellaneous
pieces of rock sitting in my front yard. Some of these were collected by my
husband, Larry (now deceased), but most were from a friend's father. When
the friend moved to TN she did not want to take the small rocks.
Rock
hounding was my husband's hobby. I have no use for the rocks and my son and
his family do not want them. I was wondering if they would be useful for
grab bag items or for any other purpose to the club or individual members.
I
would like to have the wheelbarrow empty by the end of this summer. If no
one wants these rocks, I will simply dump them as fill around my property.
If someone from the club wants to come up to my home in Boulder Heights and
look at these pieces, just call ahead so I will know you are coming
(303-442-7256) and I will give you directions.

Bill Hayward
On
Tuesday April 24th a dear friend of the rock and mineral community passed
away. Bill Hayward was a well-known and highly respected mineral specimen
collector and dealer. Those of us who have seen his home and have been
privileged enough to "rummage" through his treasures know that he
had a story for each adventure, each pocket discovered and each mineral
specimen found. I haven't been friends with Bill as long as many of you but
over the last twenty years we have shared the common bond of digging up
Earth's treasures. We had our trips into the field, dreams of the next
great find and whispers of secrets taken to the grave. He had immense
dedication to the field, whether collecting and documenting the specimens
themselves or just accumulating the knowledge and lore of mineral
collecting, especially in Colorado. His knowledge would have filled
volumes. Some of the stories were a bit repetitive over the years but then
out of nowhere he would state in a matter of fact voice "I told you
about that garnet, or amazonite, or topaz locality didn't I?".... You
never knew what he might dig up out that vault of knowledge that he carried
around in his head. We will miss him.
