Our current classes are canceled. We will inform our students when classes are resumed.
The concept of birthstones goes back many centuries, its origins most likely tied to the biblical story of Aaron’s Breastplate.
Relating birthstones to one’s birth month in some ways similar to relating one’s birth to astrological signs. Birthstones are certainly popular today, and are one strategy many use in buying a gift of jewelry for a friend or loved one.
The gemstones used to represent each month have changed through time, in part related to the abundance or favorability of a particular gemstone. Geologist Walt Lombardo of Nevada Mineral & Book Company will discuss the history of birthstones and its evolution over time; and show how birthstone choices have changed and been influenced by the jewelry industry.
As always, wearing headphones to prevent microphone feedback is encouraged.
The Public is always welcome to join our meetings!

Free Lecture: METEORITES ON ICE: COLLECTING AND STUDYING ANTARCTIC METEORITES
Lecturer: Dr. Emilie Dunham; UCLA
Although meteorites are found all over the world, Antarctica is a prime searching location. Over the past 40 years, nearly 25,000 meteorites have been collected across this cold desert. I was a member of the 2019-2020 ANtarctic Search for METeorites (ANSMET) team and helped to collect 346 meteorites. I learned about the history of meteorite hunting in Antarctica, how to find meteorites, and how to survive a month living in a tent hundreds of miles from the nearest people. ANSMET has contributed significantly to meteorite collections. Amazing discoveries have been made about the formation and evolution of the Solar System formation through the study of Antarctic meteorites. Join me on a virtual journey to Antarctica!

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.

2020 Fee Free Days on Federal Public Lands
Here are the 2019 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 20 – Birthday of Martin Luther King, Jr.
April 18 – Start of National Park Week / National Jr. Ranger Day
August 25 – National Park Service Anniversary
September 68 – 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.
