SDAG Events / Announcements

PRESIDENT'S CORNER:

Greetings SDAG Members

Sadly, the 2024 SDAG Annual Field Trip needed to be postponed due to the devastating Bridge Fire in the San Gabriel Mountains. The fire homed in on the Wrightwood and Big Pine area a couple of days after starting on the other side of the mountain on September 8. The field trip itinerary, as well as our camping and lodging area at Lion's Camp, was thoroughly impacted. Our only choice was to wait for another time. That time has been re-scheduled to September 25-28, 2025. This is a monumental field trip, based on the San Andreas Fault, organized by SDAG Vice President Heather Reynolds and Dr. Miles Kenney, with major input from Monte Marshall. The Field Trip Guidebook will be published and available soon. More information to follow. Our hearts are with the Wrightwood residents and businesses that have suffered through this tragic event.

For our October meeting, we have SDAG's own Carole Ziegler's husband Mike on board to give a fascinating talk on gravitation and how it affects astronauts and the rest of us. By request, we moved the meeting to Phil's BBQ, and we will plan to get back to Casa Guadalajara again soon.

Be on the lookout for an early newsletter for November - our November meeting will be on the first Wednesday - November 6th. It will be a joint meeting with AEG, to be held at the Fallbrook Gem & Mineral Society. We look forward to seeing all of you there!

John Teasley,
2024 SDAG President

Postponing 2024 Annual Field Trip to September 2025! Updates to come


Charles Franklin Lough (1930 - 2024)

Charlie LoughCharles Franklin Lough, 94, passed away peacefully July 21, 2024, at home in San Diego after having declining heath with heart failure. He was born in 1930 at the old Mercy Hospital in San Diego making him a true native of the area. He attended Herbert Hoover High, finishing high school at Grossmont Union High; went onto San Diego State College (not a university then), finishing his Geology BS degree at University of Arizona in 1952. His employment history included working for U.S. Geological Survey 1952 to 1953; he was in the Army in 1953, and using veterans benefits he earned an MA in Geography, training to become a teacher. Instead of entering the field of education, the state of California Department of Water Resources had him from 1956 to 1961. He and his family moved to Saudi Arabia where he worked for the Ministry of Agriculture 1961 to 1962. On returning home the family spent time exploring and living in Greece, then bought a bus and explored some of Europe. When he returned, the County of San Diego Department of Public Works took him on 1973 to 1974. From there he transferred to the San Diego Department of Planning and Land Use, his employment lasting until retirement May 1, 1992. Throughout these years he collected books on many subjects, geology maps, and, of course, rocks. He considered himself a great resource of information for many in this group. He had told me that he was one of the early members of SDAG when it first formed in San Diego.

There will be a Celebration of Charlie's Life September 7th, 2024 11AM to Early Evening
6561 Bantam Lake Ave
San Diego, CA 92119

We would love for you to attend. Please let me know if and with how many are coming. Text or Call Lore (619) 607-7879 or email loreparker@hotmail.com

SDAG received a donation of 15 boxes of geologic books and 14 boxes covering the Valecito's Mountains, from the family of Charlie Lough - our 94 year old member who recently passed. The 14 boxes with the Valecito's Mountains are based on Charlies lifelong work in that area - so we hope to find a student or University who can take these and utilize this data. The other 15 boxes of books will be brought to the August meeting for members to look thru and take any resources you would like and leave a donation if you would like. Any monies donated from members that acquire these geologic resources will be directed into a specific student Scholarship fund named "The Walawender Fund." A QR code is planned to be available to allow donations directly to the SDGS Pay Pal Account.
Any questions please contact Diane Murbach diane@sandiegogeologicalsociety.org

Interactive Fault Map for San Diego

As part of the update for the San DiegoTijuana Earthquake Planning Scenario, Working Group No. 1's "Fault Map Subcommittee" completed the first publicly available bi-national active and potentially active fault map (http://sandiego.eeri.org/?page_id=265). This interactive GIS map includes the first publicly available active and potentially fault map locations from the City of San Diego. The map also integrated the faults south of the border for a bi-national cross border view. This map is an on-going project as our knowledge increases about local active and potentially active faults.

You can expand the map legend on the left side to select layers that can be turned on or off for the map view. You can also select from 1 of 12 base maps at the base map icon. You can click on the fault line in your map layer view to see the meta-data source. In addition, the City of San Diego Seismic Safety Study Geologic Hazards & Faults Maps are available in the layer titled "GeoHaz SD City." Please note that the City "Zone 12 Potentially Active" fault layers was not included in this data, therefore you will need to use the City Maps to find Zone 12.

The Fault Map link is available at: http://www.sandiegogeologists.org/Faults_map.html

I would like to thank Carolyn Glockhoff for her endless GIS work, Jim Quinn and the City for providing their data and time, Jerry Treiman with CGS for his time preparing the Surface Rupture and providing their new State fault data layer, and Luis Mendoza at CICESE for providing the faults south of the border. Please contact Diane Murbach (dianemurbach@gmail.com 619-865-4333), Chair for the SDTJ Earthquake Scenario Working Group #1 - Earth Science, if you have any questions, or see any errors on this new fault map.

Got too many rocks? Are you (or specifically, your spouse...) interested in giving them a good home *away* from your house and garden? Mesa College is looking to collect some rock samples for an inaugural Earth History course. We are specifically looking for sedimentary rocks that include examples of different energy environments (varying grain sizes and shapes) and structures (ripples, cross bedding, planar bedding, graded bedding, etc.). We are also looking to beef up our fossil collection and are looking for all the major phyla: Echinoderms, brachiopods, mollusks (bivalves, cephalopods, gastropods), arthropods (trilobites and more!), corals (Cnidaria), Porifera, Bryozoa, vertebrates (Chordata), etc. Looking for both actual standalone specimens or in the rock still (showing different environments of deposition). We are looking for fossil preservation examples, and also for good trace fossil evidence. Got any sediment grain samples from cool locales? We'll take them! If you have anything else you think provides a good 'story' in the rock, we are willing to check it out! We are collecting ASAP to assess how much needs to be ordered for the fall course. Please contact Jill Krezoski at JillKski@hotmail.com or Don Barrie at dbarrie@sdccd.edu with queries or samples.

ROCK DONATIONS NEEDED: Amy Romano, one of our former student members, is looking for rock donations. Amy is currently attending Humboldt State University and majoring in Geology. She is very involved with Humboldt's Geology Club, and every year the club holds a rock auction to support their activities. If you have any rocks to donate, please contact Amy at ajr612@humboldt.edu.

Annual Scholarship Awards by the San Diego Association of Geologists, a program of the San Diego Geological Society, Inc.

A primary function of the San Diego Association of Geologists (SDAG) is to support academic opportunities in geology and related sciences. By-laws of the San Diego Geological Society (SDGS) specify the support of academic opportunity ranging from elementary through graduate levels. The SDAG scholarship program has supported academic research in higher education by awarding scholarships annually to students from two-year and four-year undergraduate and master's level programs. Awards are for outstanding research in geology and related sciences. Nominations are solicited from individual faculty and from geology or related science departments at accredited academic institutions. Evaluation of the relative merit of each nominee is based on an abstract describing the objectives and results of the research being conducted by the student and on the letter of recommendation by the student's mentor or nominating committee.

The annual timeline is as follows:
  • Request for nominations occurs in September.
  • Nomination letters and research abstracts are received by the Scholarship Coordinator in mid to late October.
  • Awardees and their nominators are invited to attend the December SDAG dinner meeting. Scholarship awards are distributed to the student during the December meeting.
  • Students accepting awards are required to give a presentation of their research results usually at a spring dinner meeting of SDAG.
For further information contact SDGS Board at http://www.sandiegogeologicalsociety.org/contact.html through the Contact Us option

SDAG RESEARCH TOOL

A comprehensive listing of all papers published by SDAG, whether as annual field trip guidebooks or special publications, is available on our website. Entries are sorted by primary author, or chronologically by date of publication, from our first guidebook in 1972, up the San Luis Rey River in 2013, from Coast to Cactus in 2014, and finally over the edge to the Coyote Mountains in 2015. These can be accessed or downloaded as .pdf files. They are fully searchable in Adobe Reader or Acrobat, so if you are researching a topic, "tsunami" for example, you can search for that keyword. This listing will be updated as new books are published. Thanks to Greg Peterson and Hargis + Associates, Inc., for making this possible. See the links below:

SDGS/SDAG

As many of you are aware, the San Diego Geological Society (SDGS) was formed in early 2010 as an official non-profit 501(c)3 corporation, and SDAG is now an organization under this corporation. The reasons for doing this were many and they are spelled out in an informational sheet, the Business Plan of SDGS. The officers of SDGS should be very familiar to you, as they are all past presidents of SDAG. For those of you that would like to read more about SDGS and what it means to SDAG, check out the informational page on the website. Also check out the website www.sandiegogeologicalsociety.org.
