About 15,000 years ago the final of four glacial advances stopped in central Connecticut and a large end moraine was established. As the glacier retreated a large lake formed in what would become the Connecticut River Valley. Varved (seasonal) clay/silt layers were deposited. Debris (fossils, sticks, leaves, etc.) carried in with the clay/silt became nucleation points for calcite cementation and concretions grew in the clays. These unique concretions are now being exposed by erosion. The locals call them “Ferry Stones” or “Mud Babies”.
Have you ever heard of flint knapping? Do you know there is an active group of flint knappers in western New York and they hold their annual Stone Tool Craftsman Show every August? In 2018, the event is August 24-26 in Letchworth State Park, itself a geological wonder worth visiting. For three days members of the Genesee Valley Flint Knappers Association display their wares and share advice on knapping at the Highbanks Recreation Area in the park.
Visitors to the Stone Tool Craftsman Show can see flint knapping demonstrations and learn about a variety of other skills that helped prehistoric cultures survive. In addition to learning about the making of arrowheads, spears, and stone knives, the group holds several athletic competitions involving stone throwing weapons.
On arrival the location does not look like a typical mineral collecting site. There are not any rocks to be seen. The GPS coordinates provided by Beard (2013) are smack in the middle of a cultivated field filled with small evergreen trees just off Fruitville Pike in Lancaster, PA. The field is flanked on two sides by subdivision housing and on a third side by a pair of little league baseball fields. Your first thought is that you botched the directions. Continue reading
The new theme for June seemed to be painted rocks. First, Wayne County Gem and Mineral Club member Donna Smith brought her artistic talents to GemFest and we added a new craft to the event. Using rocks we had collected from various sites throughout the previous year, Donna set up between Linda Schmidtgall’s highly popular soapstone carving booth and Dave Millis’s gem tree/wire wrapping booth, creating a virtual trifecta of craft activities for youths and adults right in front of the club exhibits. Continue reading
On the first weekend of June,. the Wayne County Gem and Mineral Club holds a two day mineral show in Canandaigua, New York. This year we welcomed a new partner to its annual gem, mineral, and fossil show. The Seneca Trailways Council of the Boy Scouts of America added GEMFEST to their calendar of events on both their Facebook page and their weekly e-mail which is sent to Scouts and their leaders across the council. WCGMC believes this is a perfect match. The involvement of Scouts aligns with both of WCGMC’s primary objectives, providing family fun and working to spread knowledge while stimulating interest in the earth sciences. Continue reading
For the fourth year is a row, the Wayne County Gem and Mineral Club held its annual show at the Greater Canandaigua Civic Center on the first full weekend of June. Attendance was up over 15%, as over 1400 folks crossed into the arena to visit the venue over the course of two days. We exceeded our expectations with our club activities, nearly running out of soapstone as 180 1.5” squares were carved, filed and polished by visitors. The sluice was busy as usual. Over 300 bags of sand with minerals, gems, shark teeth and more were run across the sluice table. Continue reading
The first weekend of May split the Wayne County Gem and Mineral Club into two parties. Many stayed in western New York and visited Penfield Quarry on the annual Dolomite Products open house. If you check out our club Facebook page you will find several had a successful day among nearly 200 collectors from across the northeast who visited that day. But others of us had planned our annual pilgrimage to central Pennsylvania for that weekend, travelling south with visions of wavellite and large lepidodendron tree stumps dancing in our heads.
We all dream of finding that special rock, one that is totally unique, one that can hold that center position on the top shelf of our mineral cabinet. Yes, that perfect piece we can be proud to display while telling the story of how we found it. In 1996, a geologist working for the Egyptian Geological Survey had his dream fulfilled. Aly Barakat was studying Libyan desert glass formed 26 million years ago, presumably by a meteorite impact, when he made his incredible find. As a geologist he knew that the colorful broken pebbles he found deep in the Saharan desert were unique, but it took more than two decades to learn how special they truly are. Continue reading
I purchased a new toy in March. I acquired a Carson zOrb 65x Digital Microscope. Although not a tool for advanced photographers, I hoped that it would give me a simple tool for illustrating details I could not depict well with my Nikon. And for $50 I decided it was worthy of an experiment.
The meeting room was crowded for our February meeting as 49 members showed up to build their own egg crate mineral collections from the club’s inventory of small stones, mineral specimens and fossils. There were over 50 options to chose from when the first selections were made.
On occasion, cleaning out that old box of leftover and generally forgotten minerals from a past trip can provide an unexpected reward. Last month I uncovered a box of rather ordinary wavellite specimens from the club visit to Mount Pleasant Mills, PA in April of 2016. Among the cruddy and generally less than desirable wavellite discards I found a fossil gastropod that I had remembered collecting, but had pretty much forgotten. It was time to clean it up and do a little research. After all, that is what the winter months are for in western New York.
Some rockhounds like to collect rocks and minerals the size of small cars, or at least motorcycles. You know who you are (and so do the rest of us!). Others settle for samples that can be carried, a size that seems to decrease with each collecting season. But we also know of those who collect thumbnail specimens (less than 1”) and stick them into tiny boxes. There are even folks who like to collect specimens that require microscopes to be seen; these collectors are called micromounters. But I am going to tell you a bit about some “mineral specimens” that are even smaller. And I am even going to make up a new name for them. I am calling them micro-micro minerals.
Topical or thematic stamp collecting is a tremendous way to diversify and expand one’s special interest. For me of course, this takes me to minerals, fossils, geology. etc. and the thousands of worldwide stamps carrying such images. But another collector in the Rochester Philatelic Association (RPA) with an interest in trains and the use of the railroad in postal history took his topical collecting in a different direction. The following is a review of his presentation to the Rochester Club in January.
In winter I spend a little time with my second hobby: philately. In addition to topical stamps bearing minerals and fossils, I also like to learn about forgotten and defunct places. Often stamps help tell that story. I am not alone with this interest among members of the Rochester Philatelic Association. In October of 2015, Steve Eisinger entertained us with his presentation entitled “Confusing, Obscure, Bizarre and Defunct Countries – Their Coins and Stamps”: fascinating stories about forgotten places.
And now, for all of us who enjoyed Steve’s presentation, there is a new philatelic book with the same theme. “Nowherelands- An Atlas of Vanished Countries 1840-1975” reviews the history and geography of some 50 vanquished countries through the eyes of the country/kingdom’s stamp issues. The author, Bjorn Berge, is a Norwegian philatelist with a keen interest in history, a tireless commitment to research, and a ability to craft a relevant and enjoyable story.
The book was first published in Norwegain in 2016 with the title Landene som Forsvant. In late 2017, an English translation became available online.
Bjorn Berge notes in his introduction, “The stamps serve as the core evidence, providing concrete proof that the countries did in fact exist.” Countries such as Karelia (now part of Russia) that existed only for 17 days in 1922. Not much time to form much of a government, but apparently enough time to issue a postage stamp (heck 15 of them!), thereby insuring its immortality, at least to philatelists. Or the Kingdom of Two Sicilies which united the Kingdoms of Sicily and Naples from 1815-1860 and issued a set of stamps depicting the kingdom’s coat of arms stamps in 1858. And then there is Inini, Biafra, Nandgaon, Obock, Upper Yafa, and this list goes on. Each entry includes a map, a bit of history, and the story behind the designs of the stamps.
The book received a positive review by Phillip Coop in the January 2018 issue of The New CartoPhilatelist, the journal of the ATA Study Unit of Maps on Stamps, and by Angela Riechers in the online October issue of Print Magazine. The 200 page book can be obtained from Amazon online for less than $20.

Last month I wrote about the Arkansas portion of Wayne County Gem and Mineral Club’s November field trip south (quartz, quartz and more quartz). But we did not stop there. After three days of collecting SiO2 in and around Mt. Ida, Arkansas, ten of us pointed our large black van east and headed to Tennessee and North Carolina. There was still a bit of space to fill in the van and in the trailer and we simply could not head north without filling all possible nooks and crannies. Here is how we did it! Continue reading
Wayne County Gem and Mineral Club throws a marvelous Christmas party each year and 2017 was no exception. When it came time for me to select my club gift from the table of bright red boxes at the holiday party I did not hesitate. I took one from the middle of the back row and went back to my table to see what I had been gifted. I was not disappointed. I opened my bright red box and pulled out a colorful blue layered rock. The label simply said “Peruvian opal”. I was pleased for two reasons: first I did not have any opal from Peru, but more importantly I knew nothing about it. I would have fun back home while the snow fell outside researching my new “acquisition”. A third bonus: as a rough piece, it will also give me something to cut and polish at an upcoming workshop.

Having collected stromatolites in several locations in New York and Ontario, I was attracted to a small polished piece offered this past October by a dealer at the Rochester Gem and Mineral show. It was labeled Kabamba Jasper – stromatolite, Madagascar. It was a pretty green color, showed physical characteristics of a stromatolitic origin, and best of all, it was reasonably priced. I bought it and came home to research the geology and age of my new find. Immediately, things got complicated.
In November of 2017, Wayne County Gem and Mineral Club undertook a 9 day collecting trip to Arkansas-Tennessee-North Carolina. This is mostly a photo essay from the first half of the trip in the Arkansas quartz district of Mt. Ida and Jessieville. Published in WCGMC December 2017 newsletter. Part II on the rest of the trip will follow.
3300 miles and 3300 pounds of Arkansas quartz: the miles are accurate, but the weight may be a bit of an understatement. Once someone started putting large clusters and quartz-covered pieces into the trailer (I think it was Glenn!) it seemed contagious. Everyone simply needed more! Buckets were filled at three sites, half bushel baskets with crystals encased in red Arkansas mud were purchased, we traded for yet more, and eventually even the spaces under the seats in the van were dedicated to Arkansas quartz. And we hadn’t even headed to North Carolina yet!
Have you ever sat down to think about where the chemical elements in all those neat minerals we collect came from? I mean in the grand scheme of things, like as the universe forms and evolves.
We collect metallic minerals, like copper (Cu) in chalcopyrite and bornite and in colorful carbonate secondary minerals like malachite and azurite. The latter require carbon (C) as does calcite with its calcium (Ca) cation and dolomite when there is sufficient magnesium (Mg). WCGMC has travelled to Cobalt, Ontario in search of silver (Ag) in its pure form as well as cobalt in arsenic minerals (Co, As).
Bruce Leis has been an enthusiastic collector and researcher of stromatolites for over two decades. He has visited them worldwide, photographing their distinctive patterns and studying their geologic setting. In 2015 he teamed up with retired professor Bruce Stinchcomb and paleo-artist Terry McKee to produce a unique book detailing these wonderful and important geologic features. Anyone interested in earth’s geologic history and the development of life on this planet should enjoy their wonderfully illustrated 176 full page size treatise.
