June 2, 2021 – 7:15 p.m. – 9:00 p.m. Online Meeting – “The Geologic Diversity Of New Zealand”
When they say “big things come in small packages” they must be talking about the geology of New Zealand. From volcanoes to glaciers, caves and fiords, it would be difficult to find so much geologic variety packed within such a small geographic area anywhere else on this planet.
Geologists Dick & Mary Pat Weber spent four weeks in 2007 exploring every corner of this tiny island nation. Join us in June when Mary Pat will take us on a tour of this fascinating country.
The Public is always welcome to join our meetings! Doors open at 7:15 p.m., meeting begins at 7:30 p.m. As always, wearing headphones to prevent microphone feedback is encouraged.

Free Lecture: Of Magnets and Meteorites: What Magnetized Meteorites Tell Us About the Formation of Asteroids and the Solar System
Lecturer: Samuel Courville; School of Earth and Space Exploration, Arizona State University
Like the magnets on your refrigerator, some meteorites are magnetic. These meteorites are known to have been magnetized in strong magnetic fields before they crashed down onto Earth’s surface. It is important to understand how meteorites become magnetized and what magnetized meteorites tell us about the history of the solar system. Iron meteorites and chondrites that have been magnetized likely acquired their magnetization on their parent asteroids. There are at least three ways that an asteroid could acquire magnetization, and each implies a different formation history for the asteroid: (1) An asteroid could generate its own internal magnetic field and magnetize itself. (2) An external magnetic field could magnetize an asteroid. (3) An asteroid could become magnetized by the accretion of previously magnetized grains. Each mechanism requires different asteroid formation times and different degrees of thermal evolution. Despite the presence of magnetic meteorites, no asteroids have been robustly confirmed to be magnetic.

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.
