It is my pleasure as AEG Chair of the southern California section to invite you to join us on Saturday, June 11, 2016, as we embark on a Field Trip along the Santa Monica and Malibu Fault Zones. This is our follow-up field trip to last-year’s highly successful field trip along the eastern portion of this fault.

We plan to start the field trip promptly at 8am, and proceed east to west, starting where we left off last year. We will be travelling by bus once again. There will be a maximum attendance of 60 people including speakers and organizers. The per person trip fee will be $110, slightly more than last year, which reflects some additional transportation costs and longer travel distance for this year’s trip.

The stops have been tentatively planned at locations of significant investigative activity and of general interest to engineering geologists. We encourage invited speakers at each location to present a visual aid such as a poster to facilitate the presentation. We will utilize a loudspeaker PA system for each speaker. A road log will be provided on the day of the field trip, and we hope to produce a field trip guide with summaries of each stop location with input from each speaker, within the ensuing months following the field trip.

The tentative schedule is as follows:

Stop 1, 8am: Veterans Administration, corner of Sawtelle Blvd. and Dowlen Drive. We have submitted a formal request to use the VA parking lot as our rendezvous point and staging area for Stop 1. If for whatever reason we are unable to secure access, the meeting point will be shifted off nearby this location but off VA grounds, Exact location TBD. The main speaker at this location will be Miles Kenney, who has prepared some sophisticated geomorphic models of the fault in this vicinity. Workers who have performed investigations on the VA grounds are encouraged to join the discussion.

Stop 2, 9am: University High School, secured parking lot off Barrington Road, southeast part of campus. This parking lot is just north of the Tongva Springs, which is considered the main trace of the fault. We are also in the process of securing access to this parking lot with LAUSD. If we are unable to secure access to this location, we will meet nearby on the sidewalk or other suitable location. David Perry will lead the talks regarding the several investigations done on this campus.

Stop 3, 10am: Brentwood Knoll, Montana Avenue south of Brentwood Country Club. This topographic high was first identified as such in the USGS Topographic Map of Los Angeles County from 1923, and Hoots Geologic Map of 1931. There have not been any studies done at this site since most development here took place prior to it being recognized as possibly being related to uplift and movement along the Santa Monica Fault. Our main speaker at this location will be Brian Olson of the California Geologic Survey.

Stop 4, 11am: Temescal Canyon Park. We will enjoy an early lunch and ocean views at this location, where Casey Jensen of the Los Angeles Department of Building and Safety will discuss the evolving requirements for fault studies in the city of LA. Don Michael will also lead a discussion of landsliding along PCH and their relationship with faulted earth materials along the fault zone, which will continue as we drive westward along PCH.

Stop 5, 12:30pm: Los Liones Trailhead, Los Liones Drive, Pacific Palisades. We will stop at one of the popular trailheads that lead hikers and equestrians to the Parker Mesa in the Santa Monica Mountains. Here, Philip Shaller will be our main speaker and will discuss coastal uplift of marine terraces related to tectonic activity along the Santa Monica-Malibu fault zone.

Stop 7: 1:30pm: Michael Landon Community Center, Malibu Bluffs Park, Winter Mesa Drive. At this location, Eldon Gath and Roy Shlemon will discuss numerous fault studies done in this area that first resulted in the area being designated an AP fault zone, only later to be overturned and removed from the fault zone designation, the first and only time an AP zone has been rescinded.

We plan to return to our original parking location at VA by 3:30pm and no later than 4pm.

We hope you can join us. It is our second such field trip following on the success of last year's trip, and there is considerable interest so please act early and sign up. Spaces are expected to sell out.

As a note, this event is not open to the public and is extended to members of AEG, South Coast Geologic Society, and ASCE Geo Institute only. We will be maintaining strict accountability of potential registrants so non-members will not be allowed to attend.

2008 AEG Southern California Section’s 3rd Annual Golf Outing to Benefit the Martin Stout Fund

The Southern California Section of AEG held their 3rd Annual Golf Outing at Tierra Rejada Golf Club in Moorpark on Friday, August 15, 2008. The event is held to benefit the Martin Stout Fund of the AEG Foundation. In keeping with tradition, the event was held at a course providing some geologic interest and member Scott Simmons of Gorian and Associates was on hand (with exhibits) to present findings of his work on the property to the group. In brief, the property is traversed by a potentially active trace of the Simi Santa Rosa Fault with attendant fault-related features such as landslides and unconformable contacts between geologic units. Thanks to Scott and Gorian and Associates for providing color!

This year's event was won by the two-man team of Mike Phipps and Shaun Simon of Geolabs-Westlake Village. Congratulations Mike and Shaun! Second Place was shared by the two-man teams of Paul Kim/Dave Benson and Martin Lieurance/Jeff Kofoed all of Grover-Hollingsworth, also located in Westlake Village. Well done Paul, Dave, Martin, and Jeff! Individual prizes were won for closest-to-the-pin by Lee Gonrab (non-member associate of Earth Resources) inching out Donnallee Simmons of team Gorian on Hole #2, Jon Relyea of Earth Resources on Hole #14, and Martin Lieurance of Grover-Hollingsworth with a spectacular shot on Hole #17. Mike "Big Dog" Phipps out-distanced all to win longest drive on Hole #16. Congratulations to all on their individual performances!

As in previous years, the event was a financial success as well as a fun outing and the Section will be donating all proceeds to the Martin Stout Fund. Special thanks to Buzz Spellman as the official photographer for the event, and to Shaun Simon for keeping statistics. Honorable mention to Lee Gonrab for returning his individual prize as a donation to the fund in the spirit of the event.

The 2007, 2nd Annual AEG Southern California Section Golf Tournament (proceeds to benefit the Martin L. Stout Fund) was held on Friday, July 13. It was held at the Los Verdes Golf course in Rancho Palos Verdes (a public course). Following the tournament was a catered BBQ at Point Vicente Interpretive Center Park. It was a beautiful setting on the bluff overlooking the Pacific. The food was outstanding, the company better, and apparently beer consumption was OK with applicable authorities. The ultimate view was seeing blue whales spouting on the horizon. Hope you can join us next year.

The 2006 AEG Southern California Section’s first annual golf tournament the Inaugural at Industry Hills was held on August 4. The event was held to benefit the Martin L. Stout Fund of the AEG Foundation. Although the turnout was lighter than we had optimistically anticipated, we had a solid turnout of both members and sponsors, and a good time was had by all. We achieved a modest, but significant surplus to donate to the Fund. We look forward to building on the success of this event to raise even more money for the scholarship prior to the 2007 National meeting at Universal City.
