Guests are always welcome at our meetings! They are held on the first Wednesday of the month (excluding holidays) at 7:30 PM, currently online. We look forward to resuming our in person meetings at the Oxnard Performing Arts Center (map below). The format includes an educational presentation, followed by refreshments, and a short business meeting.
Our Pebble Pup meetings are held on the third Wednesday of the month (excluding holidays) at 6:00 PM – 6:45 PM.
Due to the February 2022 early morning fire at the Durley Park Art Center, our classes will be canceled until repairs are made.
Wednesday, September 7, 2022 –7:30 p.m. – 9:00 p.m. – Online Meeting – “Fluorescence, History, Mechanism and Applications”
When an object emits light of a longer wavelength than the light it absorbs, this phenomenon is called fluorescence. Fluorescence has many practical applications in medical devices, radiation detection and chemical analysis.
A lot of minerals fluoresce and that has made fluorescence an exciting part of mineral collecting and prospecting.
Howard Heitner’s talk will cover some of the history of mineral fluorescence and the ultraviolet sources available to today’s collector.
The Public is always welcome to join our meetings!
How to join the Zoom meeting:
As always, wearing headphones to prevent microphone feedback is encouraged.

September 18, 2022 – 2:30 p.m. Online lecture
Presentation: Mineral Evolution and the Rise of Mineral Informatics
Lecturer: Dr. Robert Hazen; Carnegie Institution for Science
The story of Earth is a 4.5-billion-year saga of dramatic transformations, driven by physical, chemical, and biological processes. Sequential changes of terrestrial planets and moons are best preserved in their rich mineral record. Earth’s “mineral evolution,” began with a score of different mineral species that formed in the cooling envelopes of exploding stars. Dust and gas from those stars clumped together to form our stellar nebula, the nebula formed the Sun and countless planetesimals, and alteration of planetesimals by water and heat resulted in the 300 minerals found today in meteorites that fall to Earth. Earth’s evolution progressed by a sequence of chemical and physical processes, which ultimately led to the origin-of-life. Once life emerged, mineralogy and biology co-evolved, as changes in the chemistry of oceans, the atmosphere, and the crust dramatically increased Earth’s mineral diversity to the more than 5800 species known today. Data-driven discovery in mineralogy exploits large and growing data resources, coupled with powerful analytical and visualization methods, and is ushering a new era of “mineral informatics.”
Meteorites represent one of the most unique collectables in our solar system, and not just for their “out of this world” origins. Their ability to be subdivided and still maintain scientific and monetary value forms the basis of the unique symbiosis that exists between the scientist/researcher/curator and the hunter/dealer/collector communities. For this relationship to expand and strengthen requires not only care but understanding as well.
This presentation will provide insights into how meteorites are brought to market and science, the positive roles of hunters, dealers and collectors in the advancement of science, and the motivations driving the various parties along the chains of custody. The goal of the presentation is to increase mutual respect and understanding by addressing complex issues impacting our communities so that we may work more closely together.

December 2, 2020 – “Excavating a Fossil Sea Cow on Santa Rosa Island”
Join Dr. Jonathan Hoffman, Dibblee Curator of Earth Science at the Santa Barbara Museum of Natural History (SBMNH), for a look at the excavation and preparation of fossils from ancient seas and what we’re learning from them. Recent reports of fossil sirenians, or sea cows, from Channel Islands National Park have extended the fossil record of these unique marine mammals. In 2017 and 2018, the SBMNH excavated the skull and skeleton of a potentially new species of sea cow on Santa Rosa Island. The fossils from that excavation also include mollusks and crabs that give researchers clues to what the environment was like millions of years ago and how the Santa Rosa sea cow fits into the story of sirenian evolution as they spread around the world.
Aaron J. Celestian, Ph.D. has spent a great deal of his career finding ways to safely separate toxic elements from the environment that are remnants from our energy production, such as nuclear, fossil fuel, and battery. Being able to selectively lock these elements inside molecular holes in crystals, and safely store them in the crystals for the long-term away from living organisms, is a significant advancement. This work is still ongoing, yet newer discoveries have opened the door to using these same minerals to extract critically needed elements from otherwise toxic environments. Celestian is currently looking for new minerals that can selectively absorb these crucial resources, or design new ‘minerals’ when known species do not work.
October 7, 2020 – “Fluorescent and Unique Minerals of Franklin New Jersey”
Geologist Sandy Zucker will discuss the history and geology of this world famous, unique ore deposit and mineral locality, highlight some of the rare minerals found here, or only found here, and take you on a visual tour of the dazzling fluorescent mineral displays found in the mines of Franklin and Sterling Hill.
July 1, 2020 – Rare and Unusual Gemstones of California
California is an extraordinary state for rockhounding. Geological forces have created one of the widest varieties of rocks and minerals found in any state. Known as the ‘Golden State’, California has named Gold as its state metal, Serpentine as the State rock and Benitoite as the State gemstone. This talk will feature benitoite, lapis lazuli and vesuvianite. Our presenter will be Geologist Walter Lombardo of the Nevada Mineral & Book Company.
June 3, 2020 – “Magical Obsidian of Davis Creek” 7:00 p.m.
We will “open” our doors at 7:00 p.m. to allow our Members to socialize. We will begin the meeting at 7:30 p.m. Terry Wilson will show us colorful obsidian collected on the 2018 CFMS trip to Davis Creek, California. Her talk will outline the trip itself, the various types of obsidian found in the area, and include tips for working with obsidian. Terry has exhibited rainbow obsidian in the last two Ventura County Fairs, cabochons showing the cat-eye effect with rainbow obsidian, and rainbow obsidian in the rough, respectively.

2022 Fee Free Days on Federal Public Lands
Here are the 2022 fee free days offered for recreation sites under the management of the National Park Service and the U.S. Forest Service. While many parks, facilities and services associated with these agencies are free, some require a fee. Recreation fees, authorized by the Federal Lands Recreation Enhancement Act, enable federal land management agencies to reinvest in the management of various recreation sites.
2020 Fee Free Days
January 17 – Birthday of Martin Luther King, Jr.
April 16 – Start of National Park Week / National Jr. Ranger Day
August 4 – Anniversary of Great American Outdoors Act
September 24 – National Public Lands Day
November 11 – Veterans Day
$1,000 Reward – Death Valley National Park
Fossil Thieves stole several fossilized footprints, which had been left in a lakebed by mammals and birds, were missing. Now, Ryan F. Mandelbaum reports for Gizmodo, the National Park Service is asking for the public’s help in identifying a group of backpackers who may have information on the ancient tracks. In a statement, the National Park Service released the photos of three men who might have witnessed the crime or have knowledge about the disappearance of the footprints. Investigators are offering an award of up to $1000 “for information leading to the identification, arrest, and conviction of those responsible,” the statement reads. According to Mandelbaum, investigators are planning to interview visitors who frequented the Park at the time of theft, in the hopes that someone will be able to provide valuable clues.
Destroying—or pilfering—the property of national parks is prohibited by law. “It’s illegal to collect fossils, rocks, or anything else in National Parks,” Park Superintendent Mike Reynolds said in a statement about the fossil thefts. “The purpose of National Parks is to conserve the landscape and everything it contains for the next generation. I ask that visitors come and enjoy all there is to see, and to leave it unimpaired for others to enjoy.”
The National Park Service has asked anyone with information about the stolen fossils to call the Investigative Services Branch at 1-888-653-0009.
