SDAG Events / Announcements


February 2018,

We have now stepped through the door of January; looking back, we awarded the remaining scholarship awards, enjoyed a noteworthy rainstorm, a 7.9 magnitude earthquake shake the Gulf of Alaska, and a great One Stop Wonder coordinate by Rob Hawk.

February will be an interesting month; it will be a month without a full moon. On February 1st and 28th you might say "Rubbish. The moon looks full to me." Awe, but wait, the moon might look full, but it will lack 1-3% for full illumination!

Looking at the forecasted weather for the initial 42% of February, I boldly decree that 2017/2018 shall be known as the year without a winter for San Diego, California. I really hope to be wrong, but maybe I only need to lounge on the warm winter sands to enjoy the SoCal weather and retract my statement.

For this month's meeting we will entertain the celestial objects in the sky. Many have witnessed the Great American Eclipse, but few understand the technical details associated with taking a quality photo. I myself have returned from the field and reviewed photos taken to document critical geologic features, only to be disappointed at the result. Photography is an art that requires a multitude of variables that can arguably be branded a science. I look forward to seeing you at our February meeting when Chuck Houser presenting on Photographing the 2017 Great American Eclipse.

One Stop Wonder - Oceanside Fault - Geotechnical Mapping - Sunday Feb 18th!!

Our President Chris Livesey will be hosting the OSW at a job site in Oceanside where he has been performing the As-Graded Geotechnical Mapping of the site excavation. The main focus will be on a fault that was exposed in the excavation. Please note ***date and time of OSW is subject to change depending on wet weather and/or grading conditions***


Recently, I have performed geotechnical mapping for a small grading project in Oceanside, Ca. During historic review of the site, a non-active fault transects the site. Although not as intriguing as an active fault, the exposure presents a chance for students and young professionals to see a geologic fault.

Grading operations have revealed more interesting than anticipated features. I have been attempting to time this OSW as best I could, although a majority of the exposure has been concealed by placement of engineered fill, I believe there remains enough to show the extent of the feature.

This OSW will be very informal. I intend to give you access and discuss briefly what is exposed. Other attendees familiar with the fault or geologic units (see map below) are welcomed to jump into the conversation. The fault offsets San Onofre Breccia (or Paralic deposits depending on the map) and Santiago Formation. If there are students attending I can briefly discuss the project grading. Afterwards the group can depart or regroup at Bagby Beer Company down the street.

Important: Please email me at (subject line: OSW Oceanside Fault), if you are attending. If nobody plans to attend....I myself will not attend.

The owner has agreed to allow us temporary access, based on the education nature of our visit. Although construction equipment will not be working, the site is active and at a minimum please wear hiking or sturdy boots. Your professional attitude will also be appreciated.

When: February 18, 2018

Where: Park at 1640 Oceanside Blvd., Oceanside, Ca.
enter off Oceanside Blvd just west of Vine Street. Overflow, park at your discretion.

Time: 10am-12pm

One Stop Wonder - La Jolla Shores

January One Stop Wonder - La Jolla, JANUARY 28, 2018 11:30 AM

A group of SDAG and SDSU geologists and students are having a field trip to the La Jolla Preserve at low tide. The group and the trip are open to anyone, it is free, and only loosely organized. Students are encouraged to attend to learn about the local geology as well as meet practicing professionals in your chosen field. The plan is to meet at the beach by the Marine Room at 11:30 AM on Sunday, January 28, talk about the geology, including the RC fault, then walk south into the La Jolla Reserve to look at caves, tilted bedding, and tide pools. Coast access is through a sidewalk south of the Marine Room. Low tide (-1.1) is at 1:19 PM, sunset is at 5:19 PM. Even if you're not that interested in geology, it's an opportunity for a spectacular day on the beach in La Jolla at one of the most beautiful locations in SoCal. Feel free to bring friends, kids, family.

NOTE: Dogs and beer are not allowed on San Diego beaches. About 4 PM or so, some of us will adjourn nearby to The Rock Bottom Brewery to debrief and discuss our findings. . Email for questions.

Puerto Rico geology

Sad, but true... now may be a good time to look at the geology of Puerto Rico without all the obscuring vegetation which Hurricane Maria removed.

NEW Interactive Fault Map for San Diego

As part of the update for the San Diego-Tijuana Earthquake Planning Scenario, Working Group No. 1's "Fault Map Subcommittee" has completed the first publicly available bi-national active and potentially active fault map. This interactive GIS map includes the first publicly available active and potentially active fault map locations from the City of San Diego. The City of San Diego fault locations and activity of faults are based chiefly on interpretation of information contained in geologic reports by private consultants. The City of San Diego identifies active faults as Holocene (<= 11,000yr) and potentially active as Quaternary (up to 1.6my). City of San Diego fault investigations are ongoing that may require future revision of this map. This map is not a substitute for a site specific fault investigation. The map also includes an updated fault map layer from the State CGS. CGS suggests users defer to the City of San Diego fault data, where marked, for increased accuracy. The map also integrated the faults south of the border for a bi-national cross border view. You can expand the map legend on the left side to see the fault ages and sources for each layer that can be turned on or off for the map view. You can select from 1 of 12 base maps. You can click on the fault line on the map to see the meta-data source. This map includes the yellow dashed SURFACE FAULT RUPTURE location layer that will be used for the infrastructure, social, and economic impacts and emergency response for the update to the Earthquake Scenario. In addition, active and potentially active fault investigation locations from private companies are planned to be added to this map as a resource. This map is an on-going project and resource as our knowledge increases about local active and potentially active faults.

The link is available at:

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 (, Chair for the SD-TJ Earthquake Scenario Working Group #1 - Earth Science, if you have any questions, or see any errors on this new fault map.

Photo of the month CALL FOR PHOTOS!
That's right!...It's back, the SDAG monthly photo competition, featuring the very best of member photo submissions from around the County and beyond. The prize is one free drink at the next meeting, so if you're a winner, just see our resident bartender extraordinaire, Cari Gomes at the next meeting.....or myself (The Secretary) if it's not a SDAG libation supplied event.

An approximately 20 ft long tower of sandstone that collapsed intact onto the opposite wall of Slot Canyon near the western slopes of Borrego Mtn. Slot canyon is a fairly well-travelled attraction in Anza-Borrego State Park. I can't imagine why this seemingly fragile tower of moderately cemented sandstone stayed intact but you can be sure that it could fail onto the trail below at any time.

Mark your calendars! The 52nd annual meeting of the Association of Earth will take place in Niagara Falls, New York, September 26 to 29, 2018.

AESE's meetings generally consist of 2 days of technical sessions and a 1-day field trip. Please join us for a fun-filled and educational experience September 2018. Meeting headquarters will be the Conference and Event Center Niagara Falls. The meeting hotel will be the Sheraton at the Falls, on Third Street, where a block of rooms has been set aside for attendees, at a nightly rate of US$139 ($129 for room + $10 facility fee).

Niagara Falls has been a prime tourist destination since the mid-19th century. People come from around the world to see just the falls, themselves. But there is so much more to explore on both the American and Canadian sides of the falls, from world class wineries, Niagara Falls State Park (providing close access to the American and Bridal Veil falls), Niagara Gorge hiking trails, and art galleries to the Schoellkopf Power Plant museum (providing easy access to the bottom of the gorge), Niagara rapids jet boat tours, Old Fort Niagara, Niagara-on-the-Lake and remember to bring your passports if you wish to take in all that the area has to offer!

The meeting is open to anyone interested in earth science editing, publishing and outreach. The program is in the initial planning stage. Watch for meeting updates on AESE's web page A closed Facebook group has been set up to share information . For more information, please contact host chair, Marg Rutka,, and technical program chair, Phil Farquharson .

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 or Don Barrie at 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

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 through the Contact Us option


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:
