CALIFORNIA SEA FLOOR SURVEY
SHEDS NEW LIGHT ON BIG WAVES

New Sonar Data Helps Explain Why ‘Mavericks’ Waves
are Among Nation’s Largest

This map (click image for larger view) shows the geographic range of the north-central coast study region for the current phase of the Marine Life Protection Act implementation process. Seafloor mapping data is being collected throughout this entire area to provide habitat distribution information.
This is a regional map (click image for larger view) showing National Marine Sanctuary boundaries, Bay Area faults, and the location of the data collected at Mavericks.
Over the last decade, the Mavericks surf break has captured international attention. An interesting question is, “Why do such big waves break here?”

This is a map of shaded bathymetry with wave lines on it. The blue lines show hypothetical large wave crests propagating in to shore from the west. As the waves move into shallow water, they begin to interact with the seafloor (“shoal”) and their crests slowly bend to try to maintain their roughly parallel orientation to the bottom contours. The more the waves interact with the seafloor, the more they slow down and bunch up. Wave “rays”, or the pathways of wave energy, move perpendicular to the wave crests. In areas where the wave rays, and hence wave energy, diverges, the wave height decreases. Conversely, in areas where the wave rays, and hence wave energy, converges, the wave height increases. Due to the steep topography of the bedrock reef at Mavericks, the wave energy rapidly converges and the wave height rapidly increases, creating a huge wave compared to the adjacent areas.

The dominant wave direction off the central coast of California during most of the year is from the northwest. These waves propagate over the much gentler topography to the northwest of Sail Rock and are generally too small to shoal and break at Mavericks. Sometimes during the winter months, however, strong North Pacific storms generate large, long-period waves from more westerly directions that shoal and break over the bedrock reef just to the east of Sail Rock. The abrupt topography of the bedrock reef causes wave energy to converge over the reef, causing the wave to rapidly slow down, shorten in length and substantially increase in height relative to the areas just to the north and south of the east-west trending reef. This interaction of the geology and oceanography is what makes the wave at Mavericks so spectacular compared to many other locations along central California.

This fly-through begins approximately ½ mile offshore from Pillar Point north of Half Moon Bay. The area we are looking at in detail is a shallow nearshore reef in the vicinity of the San Gregorio fault, a major active fault within the San Andreas fault system. Motion on the fault zone has uplifted and deformed the rocks in the area near Mavericks into the S and J shaped folds we see on the seafloor.

The 3-D image is color-coded by depth: the blue and green areas are deeper than the areas in yellow and red. You can see how rugged the sea floor is in this area with lots of ridges, valleys, chasms, and pinnacles.

The new data indicates that Mavericks is above a portion of the rocky reef that is shallower than the surrounding rock. As a wave front approaches the shoreline and progressively enters shallow water, it becomes compressed and grows taller. The ridge promontory also has the effect of focusing wave energy and the wave height rapidly increases, creating a huge wave compared to adjacent areas. About here (the highest red we see), the wave becomes unstable and breaks. In fact, the data collection stopped here because the rough sea conditions made it too dangerous for the scientists to operate their boat!

Although interesting for explaining the mystery of Mavericks, scientists and resource managers will be using this data to identify hazards to navigation, classify different habitat types, locate biological hot spots, and study the San Gregorio fault.

This is where our adventure-seeking Coastside photographer Michael Powers was–stopping to visit with kids from a Masai tribe in eastern Kenya] on his way to climb Mt. Kilimanjaro in Tanzania.

Few people know that long ago I put on my carpenter clothes, brought my hammer down to Miramar Beach and helped nail some redwood shingles onto Michael’s famous geodesic dome. Incidentally, Michael told me,  “I’m still looking for a creative spirit with fire in the belly to share our new studio… if you know of someone who might fit here, have them call me asap! 650- 726-2748.”

If you think you’re a candidate, call Michael.

When I first landed on the Coastside, and became intrigued with local history, I met with Louie Miguel, whose father, Joseph, was one of the masterminds behind the spectacular Palace Miramar Hotel. Louie offered good background info and also talked about the US military taking over his father’s buildings during WWII.

[The military moved into many of the Coastside’s public buildings, and most certainly, those located on the beach side of the highway, as the Palace was.]

Camp Miramar

Story by Command Sergeant Major (CA) Dan Sebby

The former Camp Miramar was established on 21 April 1943 when the U.S. Army entered into leases with several land owners in order to provide for a camp to house infantry units assigned to the Western Defense Command. The 1 June 1943 edition of the Station List of the Army of the United States, issued by the Adjutant General of the U.S. Army, stated that a single rifle company, Company G of the 125th Infantry Regiment, was present at Camp Miramar.

At the time of acquisition, there were two major buildings that the U.S. Army took control of. The first was the Miramar School, a small elementary school that served the local faming community and located on the eastern parcel, between State Highway 1 and Valencia Street. The other major building was the Palace Miramar Hotel and Resort, a large redwood-shingled building located on the beach in the western parcel of the Site.

To these substantial buildings, the U.S. Army added several temporary barracks, mess halls and support buildings. These were of the Civilian Conservation Corps (CCC) design developed by the U.S. Army Quartermaster Corps in the late 1930’s. These prefabricated, wood framed buildings could be assembled in as little as three hours by joining components with lag screws. Creosote soaked posts served as the foundation for these buildings. With the CCC buildings included, the post had a capacity to house 495 soldiers.

In a letter to the Adjutant General, U.S. Army; dated 23 January 1944, the Western Defense Command identified the Site as vacant and excess to its needs. On 11 May 1944, Office of the Chief of Engineers at the War Department approved a request from the Bureau of Yards and Docks of the Navy Department for the six of the barracks and one on the latrine buildings. This transfer of the buildings to the Point Montera Anti-Aircraft Training Center was made without the U.S. Navy becoming responsible for restoration the land on which the buildings were situated.

From September until December 1944, the U.S. Army terminated its leases for the Site. A 1946 aerial photograph does not show any of the CCC buildings remaining. On 6 May 1952, the U.S. Army terminated its permits for water and sewer lines that ran along State Highway 1.

Only on rare days like today– when the gusty winds are blowing sideways, and the surly waves are whipping up a froth–do the kite surfers come to our shores….and they were here today where I encountered Luis, a Brazilian filmmaker.

(Photo: Brazilian filmmaker Luis…The pix below are mine and I wish Luis would send me his!)

Luis was making a film about the kite-surfers–some of them his friends. These were not ordinary kite-surfers–they were professionals athletes being swept by the winds 30 feet into the air, making elegant sharp turns (like professional ice skaters) in the surf. At one point there were at least a dozen of these giant, colorful kites in the air.

Hi June,

I was in a quandary, as to which, of the myriad of metaphors for lack of early success to use, to describe my second attempt to reach “Acid Beach.”

Anything worth having is worth working for,” was a contender, but since in my mind, work is being paid for doing things you don’t want to do, that metaphor didn’t seem right. After considering a handful of others, I settled on the accurately descriptive, but not future predictive,

“So Close, Yet So Far.”

(Photo: ) So Close, Yet So Far” shot from my turnaround spot, Chicken’s Roost. Courtesy John Vonderlin.)

And I was close, like a prisoner staring out at freedom from his cell’s barred window.

After a mile- and- half of beach walking, clambering over numerous algae-slickened rocks, splashing through shallow water between waves in a number of spots, losing Meg, my quest partner’s companionship, at one treacherous spot, requiring me to crush a number of barnacles and mussels while sidling along the cliff to keep from swimming, a stomach-scraping to-my-limit muscle-up from a slippery toehold onto a sheer 8 foot wall’s top, and finally hand and toe-holding my way up a 20 foot cliff to the top of a promontory projecting into deep water, I was stopped.

(Photo: That’s Meg waving good-bye at her turnback spot. I was able to clamber along the slimy cliff along the path indicated by the white dots thanks to the traction barnacles and mussels provided. Sorry guys, I know your life is tough enough as it is. Courtesy John Vonderlin.)

Oh, I probably could have inched along the slimy, narrow, littered with scree ledge under the cliff, rising above me without falling into the unknown depths of the surf waiting below. But, I wasn’t sure I could climb back up when I returned.

Staring at my route forward I was assaulted by other doubts. Could I protect my camera during a fall? Or, after landing in the steep-sided inlet roiling with surging waves? And what about the two other tough spots ahead, still between me and my destination, that I had judged the most impassable when looking at the large photo files on California Coastal Records Project website?

Would descending from the cliff I was standing on just put me between a rock and a hard spot? What if I injured myself? Meg would never get past the muscle-up spot or on top of this cliff I was vacillating on, even if she finally got worried enough when I didn’t return and managed to traverse the area that had stopped her a quarter mile back.

Artist Michael Bowen, who lived at Tunitas Creek and hung out at the Abalone Factory in Princeton, brought this colorful incident to my attention and I want to share it with you.

From “Storming Heaven: LSD and the American Dream” by Jay Stevens, pp. 324-325 (1987)

“The hippies wanted to believe this desperately. But what was Kesey doing putting down LSD in the pages of the Chronicle? And what did he mean when he talked about going beyond acid? Give it up altogether? That was the Establishment’s line and the Establishment had Kesey by the proverbial testicles, what with three felony counts. The Haight hummed with speculation, much of it paranoid. According to the leading paranoiacs, Kesey’s public statements were just a smoke-screen. What he was planning was a monster Acid Test, the biggeest and most powerful one ever, the gorup mind pushed to its omega point. And either the State would shatter or…There was always a long pause as the implications of that sank in. Everyone had heard rumors that the Acid Test had turned fascistic down in L.A. And hadn’t Kesey actually said on TV, when asked what his main message for the graduating acidheads would be, hadn’t he quipped: “Never trust a Prankster!” (9) What kind of a valedictory was that?

Continue reading ““Electric Kool-Aid Acid Test”: Proposed New Movie Ressurects “LSD War” Between Kesey & the Beats”

John Vonderlin sent me this info about Tom Wolfe’s “Electric Kool-Aid Acid Test” moving from words in a book to images on the screen. Former La Honda author Ken Kesey & the Merry Pranksters are the main characters in Wolfe’s book.

What it made me think about was this: In the late 1950s some unusual and talented Beatniks were run out of their homes around the cafes in San Francisco’s North Beach and headed south where they found a temporary haven at our Princeton, north of Half Moon Bay. There’s a chapter on this in my new book, “Princeton-by-the-Sea,” due to be published by Arcadia on Dec. 10.

The story of the Beatniks, including the famous artist Michael Bowen, who lived at the Abalone Factory in Princeton, is a little known and juicy slice of local history– and I am very proud to have resurrected it, prompted by long ago interviews with Pete Douglas of the Bach Dancing & Dynamite Society in Miramar. (Pete’s also in my new book.)

What’s interesting is that these Beats who were in-your-face types, that were harassed by the cops and others, and protested on the spot–also overlapped the period that Ken Kesey was driving his day-glo painted school bus through the redwoods of La Honda.

But guess what? They didn’t get along, the Beats & Kesey. Not only a little generation gap but here’s my ice cream analogy: If the Beats were double chocolate fudge, Ken Kesey & the Merry Pranksters were definitely vanilla.

I hope Movie Director Gus Van Sant explores that in his new movie.

Hi June,

As I mentioned in an earlier email, a large portion of the non-buoyant marine debris I collect from Neptune’s Vomitorium, comes from the various fishing industries that ply our local coastal waters. In this portion are the majority of items that pose the greatest dangers to various lifeforms that inhabit the coastal areas as well as unwary beachwalkers.

But, because of their great number and astounding variety I’m happy that they have provided me with the raw materials for a sizable number of pieces of artplay. I’ve attached a few pictures of pieces from my series entitled: “Neptune’s Burden: The Ones That Got Away.”

The first two photos are of the original “Neptune’s Burden.”

It’s a work in progress, as I have a large number of small bits of lost fishing gear (hooks, swivels, leaders, etc.) to cut out of the three trash cans full of fishing line balls that I still must process and add to the World’s Largest Fishing Line Ball.

The third photo is a naturally-polished abalone shell

topped by a part of a plastic buoy in which the glass sphere full of colorful rubber fish lure remnants rests.

The last photo         is of a fishing pole’s broken remnants entangled with other balls of line and a piece of cloth. I had to do almost nothing to this.

In fact, my beachcombing partner assumed it was a fisherfolk’s homemade grave marker that had washed away when she first saw it. It isn’t, but its appearance and the proportions of its remnants dictated its use in my mind. If you look closely you can see the eyelets that guide the line on a fishing pole entangled in the mess. The mourners are composed of a pareidolic rock and marine debris pieces. Enjoy. John Vonderlin

When I first moved to El Granada, I couldn’t help but notice that some of the median strips–especially the one near El Granada Market–were filled with flowers. A sign told me that the flowers had been planted and were maintained by the El Granada Garden Club.

Garden Club members planted colorful flowers and also pine trees–Daniel Burnham style– (if you don’t know who Mr. Burnham was–he was the renowned architect who, during the Ocean Shore Railroad era, developed the unique street plan for El Granada, you know, the one you can get lost in– and, who, intended that there be vast plots of flowers and trees planted along the broad avenues.)

In the early 1900s, flowers and trees were planted as Burnham indicated in his beautiful plan. But after the Ocean Shore went bust so did Coastside real estate, and, well, there was nobody around to do the gardening.

Being a great lover of flowers and gardens, I can’t help but wonder who was going to water all those plants and trees? Who would pay for the watering? What would happen if there was a drought? Had the Ocean Shore thought it through?

Most of all, I am wondering what happened to the El Granada Garden Club….
