August 12th meeting presentation and shows

We are still holding meetings in person at the Forest Grove Senior Center (see previous post on vaccination notification and / or mask guidelines) As well as meeting online. It has been a pleasure to be able to see and greet each other in person as they share their rock treasures.

Our August 12th meeting will be a presentation by Bob Oblack entitled “Rockhounding the Molalla River and it’s Geology” for those attending in person, you will be able to view his rocks from the area near the Molalla River in person. Also, bring your rocks or minerals that you might think be fluorescent. Bob Oblack is very knowledgeable with the subject of fluorescence and will be bringing his shortwave UV light.

If you cannot join us in person and wish to attend as a guest online please send us a notification and we will send you the link to attend over zoom.


We look forward to our Club tvgc rock and gem show now approved for March 11, 12 & 13th of 2022 at the Forest Grove Armory (more information to come later). But until then let’s enjoy the upcoming Mt. Hood club rock show at the Jackson armory on August 13, 14 & 15th

Also the Biggest Event of this year will be the Portland Regional Gem and Mineral Show on Oct. 1, 2 and 3rd at the Wingspan Event Center in Hillsboro across from the airport. Our Club will need volunteers to help with this upcoming Portland Regional show (that will benefit our club) and you will be able to visit the show all three days for free for volunteering or exhibiting at this show. Please attend our meeting or ask online for more information.

Please note you will be able to view many of the rock club shows on our website calendar.

In Memory And Recognition

As some of you may already know Carl Weaver passed away on April 27, 2021. He was a huge active supporter of the club and long term member, having served on the TVGC Board and volunteering at club functions over the years. His knowledge of turquoise (and other rocks and minerals) and silversmithing benefitted the club with the free silversmithing instructions he gave to club members and the lapidary displays he had at our shows. We will miss his kindness, Generosity and smiling face. 🕊

In Memory and Recognition

Long term tvgc member, Rose Tacholsky Jackson passed away recently after a long battle with cancer. She fought long and hard and kept positive in the face of difficulty. Even in the midst of her worst days, she was still amazed by the beauty of creation around her. She was caring and proud of her husband, kids, and grandkids. She loved her family and friends and always had something wonderful to say about them and enjoyed her many memories of time spent with them. Her love of all things rocks was infectious. She and her husband Tom, would spend many days and miles traveling to rock shows and meeting up with old friends and making new ones.

We, along with her family, will miss Rose’s contributions, strength, loyalty, perseverance, joyfulness, love of beauty, and life. You will be missed! 🕊

Our May 13th Meeting, at 7:30 pm on zoom

Join us and author Leslie Moclock, (many of you will remember her as former curator of the Rice NW Museum of Rocks and Minerals) as she talks about the subject of her new book Rocks, Minerals and Geology of the Pacific Northwest, a new field guide to the landscapes of Oregon and Washington. This book helps you learn to read the story of the rocks, from how to identify and name the things you see to understanding what those features signify in the fascinating geological history of our region. It covers geology at all scales, from mineral crystals to mountains, with hundreds of photographs and many illustrations and diagrams.

Author Leslie Moclock & Jacob Selandar

Leslie Moclock has an MS in geology from the University of California–Davis, where she taught field and laboratory geology. She held the position of curator at the Rice Northwest Museum of Rocks and Minerals in Hillsboro, Oregon, for five years, where she enjoyed many opportunities to bring science to the public.

New Year Meetings Information

🎆Happy New Year to all!🎉 May 2021 be an extraordinarily good one (in health and happiness). We hope that everyone continues to grow in knowledge and come together as community in good faith.

As everyone knows, we will continue our meetings on zoom with our normal meeting times on the second Thursday until further notice. Members may wish to share the zoom link with friends also interested in rocks, fossils etc.. Also, share your favorite 2020 rock finds, stories, purchases and gifts at any of our meetings.

Join us on January 14th – For this meeting, you might also consider any fossil amber with insects or pictures of them to share. Our first meeting topic of the new year starts off with Author Dr. William Orr (who wrote “Oregon Fossils & Oregon Geology to name a few) with a presentation on Fossil Insects.

Fun fossil facts – Oldest known fossil of an insect dates back to 400 million years. One of the insects with the largest wingspan was the Meganeura (actually classified as a Griffinflies) with a wingspan of over 27 inches from about 300 million years ago that looked like a dragonfly. Discovered in France and England.

Bob Oblack is a retired electrical engineer from Tektronix. He has attended Dr. Bill Orr’s geology classes at Chemeketa Community College…to better understand the science that underlies our rockhounding hobby.
Bob has been a Rockhound ever since he was able to walk on the beach looking for agates. It’s “The Thrill of the Hunt” that drives his passion for Rockhounding. He joined the NARG fossil club and the Fluorescent Mineral Society to add breadth and depth to “The Thrill of the Hunt”.
Bob lives near the Molalla River and with support from the Molalla Culture and Art Committee created two videos about the Columbia River Basalt (CRB) flows and geologic points of interest within the Wild and Scenic Molalla River Corridor and traced the CRB flows from the Molalla River Corridor to the pacific ocean. These videos can be viewed on the Welcome Molalla YouTube channel.

Bob volunteers his time to help the Clackamette club promote their annual rock show. He shares his knowledge of Molalla Are Geology and Fluorescent Minerals with others via Home-Schooled-Children Field Trips and presentations like this.
