Education Team Report:
Our club Youth Education Outreach Program was very busy this month. At one point, our members talked at a 4th grade event, and went to our club general meeting that same evening. Then the very next morning we talked at a 5th grade event and then, that same evening, ran a school booth. A very busy time for sure! We also had an educational booth at the CFMS show on Saturday and Sunday. Then finishing up the month, we had another school booth to run. WOW! WE DID GOOD! Members who helped with all of this club activity were Bob Knox, Shellie VanWinkle, Bernadette Friedman, Pam Abbott, Diana Durfee, Dan Farber, Jeff Dengrove and Maxine & Bob Dearborn! We were tired when it was all over, but we talked to many people about our club and rockhounding. And, we still have 2 more events scheduled in June!

So, in honor of our guest speaker this month, bring in your fluorescent minerals and your UV lights to share your glowing specimens with the group.

April 2025 Program:
Here and There in the Solar System: Driving and Flying on Mars
Presented by Neil A. MottingerNeil grew up in the 50’s on a small family farm southwest of Chicago, near Joliet, Illinois. During his junior year of high school his mother arranged for him to look through a neighboring farm lad’s home-built telescope. Unknowingly, that set the course for an interest in space that ultimately found him at JPL in deep space navigation in 1967. He worked in a group dedicated to improving the accuracy of deep space navigation. He supported many of the missions to Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune as well as Lunar unmanned and manned missions, starting with NASA’s Apollo 8. He’s also supported international navigation teams in Europe, Japan, and India, including the 2023 Indian south pole lunar lander. Also supported at JPL were the first US Mars Orbiter, Mariner IX November 1971, and the first successful landings on Mars by the Viking the more recently Mars Rovers Curiosity (2012), Perseverance (2021) and InSIght lander (2018) navigation teams. Neil and his wife, Debbie, live in La Crescenta. He is active in the La Canada Presbyterian Church as a 42-year (charter) member of the hand bell choir and a practicing Stephen Minister for 28 years. He was an astronomy major with a math and physics minor at the University of Illinois, Urbana, 1966, with a master’s degree in systems Analysis from West Coast University, 1971.

April's Rock of the Month is Jasper
Courtesy Geologyln.com Jasper is a form of micro-granular quartz (Silicon Dioxide - SiO2) and/or cryptocrystalline chalcedony and other mineral phases. It's typically opaque and comes in various colors like red, yellow, brown, or green, with red color often due to iron inclusions.

April Field Trip - Lavic Siding - Paid Members Only
Saturday & Sunday April 26 & 27, 2025 Sign up Sheet at the April Meeting
Courtesy Google ImagesLavic Siding is an old railroad siding and associated hamlet in San Bernardino County, California, known for its alluvial deposits of volcanic rocks, including jasper and agate, that are sought after by rockhounds. If you ask any rockhound where the Mojave's most colorful jasper can be found, Lavic Siding will be on the short list. For decades, rockhounds have driven across the tracks and down the Lavic Lake road to access this remarkable location. Red, yellow and orange jasper with blue and white quartz stringers is still found in profusion as float in this spot. Have your rock hammers and spray bottles at the ready. More details as well as a sign up sheet at the April general meeting.

EMERY BOARDS
I feel the key to getting a lustrous polish on your jewelry work is having a good selection of sandpaper handy for pre-polishing before going to the buffer. I generally start around 400 grit and then go to 800 and 1200. While some projects do require sheets of sandpaper, my favorite way of sanding small jewelry items is to use emery boards, the ones you use for doing your nails. I like the ones with a thin foam
core. They have enough resistance to sand the high points off a flat surface and yet give a little when you're trying to smooth off a curved surface. These nail boards are inexpensive and come in a variety of grits. Some grits are so fine they give an almost finished surface. Pick up a few at a beauty supply company, at your local drug store, or from Amazon.

March 2025 Program: Tektites
Presented by: Paolo Sanchez
Tektites, glass blobs formed from the melting and/or vaporization of terrestrial rock from a meteor impact, have been known for over a century and are common. The 790,000 year-old Australasian tektites, which are commonly seen in gem shows, are found all over Southeast Asia, Australia, and the Pacific and Indian Oceans covering 10% of the Earth's surface. However, the proposed source crater for these tektites remains elusive. From stratigraphic and geophysical data, a recent study in 2019 found a potential crater buried under lava flows and jungle vegetation. This presentation focuses on what tektites are, the importance of studying them, and delves into a recent geological expedition I went on to the jungles of Laos looking at the geology and many tektites from the proposed source crater.
March's Rock of the Month is Calcite
Calcite is fluorescent so bring in your UV lights. We ask members and guests to bring in your specimens of Calcite to share with the group. Look to this page each month to learn what the featured rock will be. An enlightened club member will provide a brief, informative talk on the selected rock each month.
