Lake Superior Agates

Wednesday, October 5, 2022 –7:30 p.m. – 9:00 p.m. – Online Meeting – “Lake Superior Agates”

Lake Superior Agates are the second oldest and one of the most abundant types of agates found in the world.  Collectors around the world instantly recognize them because of their distinct fortification banding and rich iron oxide colors.

This month geologist, Dick Weber, will take us on a journey to the upper Midwest to look at Lake Superior agates.  He will show us how they formed, where they are found, and the traditions relating to their care and display.

Dick has been an avid “Lakers” fan as far back as he can remember.   He began collecting these beautiful agates during his youth, long before he became interested in Geology as a profession.

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.

November 20, 2022 – 2:30 p.m. Online lecture

Presentation: Staring at the Solar System through a Microscope
Lecturer: Dr. Elena Dobrica; University of Hawaii 

For decades, the study of chondritic meteorites has been driven by a perpetual quest to identify and understand the most pristine materials formed in the early Solar System. The goal of this presentation is to discuss the physicochemical conditions of these materials and their evolution within the protoplanetary disk and later on the chondrite parent bodies. Following asteroidal accretion, multiple secondary processes come into play, such as thermal- and shock-induced metamorphism, metasomatism, and aqueous alteration, which modify these pristine components of chondrites. These processes begin to occur even at very low degrees of secondary alteration. Therefore, understanding these secondary processes will help us to determine the characteristics of the earliest Solar System materials. Today, electron microscopy is one of the primary nanoscience tools, allowing us to carry out various observations that transform electron microscopy into a versatile micro- and nanoscale laboratory to obtain fundamental insight into nucleation, growth, and evolution of returned samples, meteorites, and dust particles.

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.

November 4, 2020 – “Minerals And The Future Of Energy Sustainability”

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.   Missed the meeting?  See the recording.

National Park Service

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

Death Valley National Park Fossil Thieves

$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.
