Images of Devils Slide

Power Spot
Devils Slide Comes Alive with
Clouds and Fog
Devils Slide is a stretch of rugged coastal terrain about 10 miles north of Half Moon Bay and about 10 miles south of San Francisco. It's a highly unstable formation with many slides and transportation disruptions. Sometime after 1906 the Ocean Shore Railroad was completed from San Francisco to El Granada. The railroad operated at a loss but major slides along Devils Slide sealed the doom of the railroad and in 1921 operations ceased. Highway #1 replaced the railroad but it as well was plagued by frequent land slides that closed the road for months at a time. Finally a new modern tunnel was completed in 2013 and it solved the major slide problems for now!

The old section of highway #1 that was bypassed by the tunnel is now a part featuring the 1.3 mile trail called Devils Slide Trail.

Fog and Clouds Collide at Devils Slide
Devils Slide is about 3 miles from my house and I visit frequently especially when there are interesting cloud, fog and storms that attract my photographic interest. However there are many attractions for lovers of wildlife and nature to satisfy ones sense of adventure and wonder! For example bird lovers will enjoy the Peregrine Falcon pair that reside on the highest part of the promontory, or nesting Common Murres, Cormorants, Surf Scoters, Shearwaters, terns, gulls, pelicans, hawks and other birds.

Sometimes whales can be spotted feeding and traveling close by on their migration. Humpbacks, Grey Whales, and Blue Whales, plus Bottle-nose Dolphins are some commonly sighted.

If you want to get you eye knocked out
If you want to get your fill
If you want to get your head cut off
Just go to bunker hill
When a physical place calls to you, quiets your mind, and stops the world, some times is called a Power Spot - a physical location which brings an individual into balance with the earth, the non-local web of all information, and with herself. A location which enables us to focus or meditate, where we are in our most impeccable balance. Don't know where this definition comes from but loosely it can be contributed to Carlos Castaneda! A lot of my photographs comes from such a spot, which is actually a turnout off of highway #1. Bunker Hill, part of the Devils Slide promontory features an old WWII military bunker and is called Bunker Hill.  A funny and unexplained situation along highway #1 is many of the turn outs and pull-offs are off-limits, especially Bunker Hill,  to motorist and well as hikers, and the San Mateo's  Sheriffs do patrol and chase people from these spots. Why they are so concerned with this is beyond my comprehension but I've had cops several times give me the circling finger to move on....which I do!

It's a Beautiful Day; Climate Change Has Arrived!

Figure 1.
Winter temperatures in coastal Southern California have been
far above any other year in living memory prior to 2014.
As the cool coastal fog and Mediterranean climate fade into distant memories it's very disturbing to hear the most ubiquitous phrase uttered by unaware people whenever the sun makes an appearance "What a Beautiful Day"! Such beautiful days are usually accompanied by dirty air, unnatural heat, high humidity, spare the air days, and cars-full of people spewing CO2 in a frantic effort to seek some relief from the heat (at their Peninsula homes) by traveling to the coast!  In the past heat waves inland usually generated wonderful fog banks on the coast that served as a deterrent to large crowds seeking sun by traveling to the coast. This has all changed Climate Change has arrived and the population at Half Moon Bay and surrounding areas are getting a first hand experience of how Climate Change is adversely affecting their very way and quality of life. Increased traffic is just the beginning, consider the warming ocean, with many warm water species, birds, fish and turtles appearing in cooler northern latitudes, many species are seeing a diminished food supply as sardines and anchovies to name a couple are getting re-distributed and species that depend on this food supply are dying in droves, California Seal Lions and Common Murres come to mind! Sea levels are rising and the surf is pounding the coast causing much damage and emergency repairs, Surfers Beach, Miramar, and Pacifica are being particularly hard hit. Reduced fog on the coast will adversely effect the remaining redwood trees as their moisture comes from the fog.

Figure 2
If you take the pulse of local people thru conversations and web sites such as Nextdoor the prevalent concern is increased traffic on the coast.  People speculate, oh it's the tunnel or we need roundabouts, more traffic lights, more lanes, more roads, but Climate Change, you must be kidding? As a long term coastal resident, there is no question Climate Change is adversely affecting our traffic and has been for several years. In the past warm clear weather brings people in droves driving highway 92 from the hot peninsula to the coast to seek relief from the heat and enjoy beautiful days in cool comfort. This is especially true in the summer on weekend days. We have been in a drought now for 4 years and even after finally getting average rain this year the drought persist and and the temperatures climb. In the past coastal residents got breaks from the gridlock traffic thanks to large beautiful fog banks that would envelop the coast for days on end in summer and winter. In winter time rains would dampen the the desires of visitors to clog our streets. That's gone, our wonderful cool Mediterranean climate has changed, and the once cool coast is heating up in disturbing fashion!  The chart below (figure 1) by NOAA shows the average coastal temperatures from January-March for coastal Southern California from 1900 to present day.   Winter temperatures in coastal Southern California have been far above any other year in living memory prior to 2014. Figure 2 shows the mean temperatures for February thru March 2016 and the deviation from the 1981-2010 normal distribution. Consider this it took a strong El Niño to produce just average rain, the next El Niño may be 18 years away, a long time to wait for drought relief!

Meanwhile climate deniers sit at their computers, google scientific nonsense and spin it to fit their uninformed beliefs. I have a suggestion for such folks, get acquainted with your very own habitat, peek outside, take a walk, look at the trees and clouds, they have a message for you, our planet is stressed, mankind is exploiting and raping it's very own support system, the planet will survive, mankind, it's doubtful!

Black Skimmers of Radio Road

BlackSkimmer Composite
Radio Road is birders term for some sewage treatment ponds located in Redwood Shores California. It's a popular destination for birders and bird photographers in the Bay Area.

On its website, the Sequoia Audubon Society says that SBSA’s landscape impoundment “is a perpetual favorite among local birders, for its fabulous numbers of waterfowl and shorebirds, and the constant hope, often fulfilled, of rarities. It is not uncommon to see over 10,000 birds from the security of your car, all close enough to be identified with binoculars (although a scope is a spectacular asset at this location. The popular SBSA “pond” that greets visitors to the plant at 1400 Radio Road, Redwood City – at the southeast end of Redwood Shores – is technically called a landscape impoundment. It was created in 1998 on the west side of the treatment plant to eliminate dust from the dry barren dirt in the area. 

The ponds at radio Road were drained sometime in 2013 due to a bird die off. It's believed the birds had the avian cholera  and thus the ponds were drained to eliminate this threat. Recently the ponds have been filled again and many birds have returned. However it looks like the sewer plant is going to rearrange their property and these ponds will be drained it about two years! That certainly looks like the end to this wonderful avian spot. 
Radio Road

Black skimmers have been observed in the Bay Area since 1994. They were first observed in California in 1962 and in 1971 in bodega Bay the first Northern California sighting. It's estimated that there is a small resident population of maybe 30 to 50 birds in and around the south bay. The radio Road area is perhaps the northern most boundary. I did observe 2 skimmers one time at the pillar point Harbor.  They have been hanging around radio road for at least the last seven years at least that's the first time I've seen them. It's been pretty certain that a visit to radio Road will be rewarded by seeing these birds.

El Niño Accelerates Coastal Erosion!

Rip-rap Permeates Pacifica Bluffs
El Niño may have not lived up to some of the early hype but the accompanying high ocean swells have reigned havoc along the California Coast!

Pacifica is totally bordered by the ocean along it's entire western side. Most of the land hugging the coast is crumbling sandstone cliffs in a constant state of retreat.

A group of large apartments located on Esplanade Street in Pacifica has made national news this year and in the past due to erosion threatening the entire buildings. The apartment complex was constructed sometime before 1972 and the land in front of the buildings has been retreating steadily over the years. In 2010 2 Esplanade buildings were red-tagged and the tenants evacuated. Recently 3/16/16 a 3rd building was yellow-tagged and the tenants ordered out. At the same time the two buildings condemned in 2010 were demolished by the city of Pacifica. It's likely the 3rd and last apartment in this complex will be demolished shortly and this saga will end.

Monster Wave Beach Boulevard
Pacifica California

Esplanade Apartments 1972
The most visual and exciting place to see high surf in action is right down at the Pacifica Pier located on Beach Boulevard in Pacifica California!  The pier has been famous for years as many people flock to it during high surf conditions and it often makes the evening news with spectacular waves. This year has been one of the more spectacular for wave action and destruction. Beach Boulevard and the adjacent houses have been pounded and damaged this year and the future of Pacifica Pier is in question. North of the pier near the Esplanade Apartments are several homes also under attack and near total destruction. A little further south is the Rockaway Beach area, another pocket type beach with spectacular surf and potential for major damage and erosion.

The Surfers Beach area may be the most interesting site for the future of highway 1 as this location is the most critical threat to the local highway infrastructure. From Pacifica to Ano Neuvo the ocean comes closest and most threateningly to the stretch of asphalt in the Surfers Beach area.  Currently emergency repairs are under way at this location due to erosion both from the wave action as well as the breakwater effects at Pillar Point Harbor.  In the past I've seen drift wood deposited onto the roadway at surfers Beach during storms. If all the elements for the perfect storm line up, high tide, high surf advisory, low barometric pressure,  high winds this could be an interesting scenario for sure. The vulnerability of this section reminds me of the situation after the March 11, 2011 Japan tsunami when a 3 foot wave from that tsunami made landfall of the US West Coast. The waves struck at fairly low tides and was only a curiosity to locals in this area, although over 100 boats were damaged in Santa Cruz as the result of this baby tsunami wave.  Looking at figure 4 and the 6.4  tide at that time makes me wonder what an additional 3 foot tsunami wave making the apparent tide over 9 feet would look like? We may not have to wait long to find out?
Mirada Road's Slow Trip to
Davy Jones' Locker

Miramar
A short distance south of Surfers Beach is the community of Miramar with Mirada Road separating the community from the residents and businesses. Many years ago Mirada Road ran about 1 mile further north all the way to Surfers Beach, that portion of the road is totally gone and it may take a monumental effort to keep the remaining road from the joining it's northern section in Davy Jones' Locker! Most days involving a little high surf and higher tides one will witness the ocean splashing and clawing at Mirada Road. Recently the wave action started to erode the south end of Mirada near the pedestrian bridge threatening some businesses and residents and forcing the closure of the pedestrian bridge.

Gazos Creek Beach

I'm on a survey team sponsored by FMSA Farallones Marine Sanctuary Association funded by NOAA! I've been involved in this survey on a monthly basis for about 6 years. Beaches along the California coast are in a constant state of sand erosion and deposition depending on season and weather conditions. It's not unusual to see 10 feet of sand raked off the beach and redeposited later at another section.  The December storms have dramatically changed the landscape of Gazos to an extent I've never witnessed before. The total beach is about 2 miles long and during most surveys access is pretty easy and the entire beach can be walked on medium to hard sand. On the December 2016 survey after heavy rains and surf this beach had dramatically changed. We could only access about 20% of the entire beach, the north end was completely blocked off with waves running all the way to the bluffs.

El Niño Less Than Perfect!

Relentless Surf Pounds California Coast
As our winter slides to a conclusion it's worth a look at the impact El Niño has had on the San Francisco Bay Area with respect to the drought, Climate Change and coastal erosion!

After 3-4 years of below precipitation the rains of 2015-16 has brought the SF bay Area back to more normal conditions! As of March 14, 2016 the annual precipitation is normal or above for many Bay Area locations. The rains started seriously in December and continued into January, however February was close to totally dry and put a large damper on the El Niño effect. Fortunately March has given  El Niño new life in the early going but looking at future projections, this may be indeed the swan song for  El Niño 2015-16. The consensus seems to be  El Niño did not live up to the initial hype and fell short of the 1982-83 and 1997-98 El Niños.

I'm pretty much convinced that our 4 year drought is not a ephemeral aberration but rather an indication of our future climate as a result of human caused Climate Change. There has been droughts in the past and I've lived thru a fairly intense drought in the 1970's. However the difference is significant in that the current climate is warmer and more humid than in the past and seems inclined on staying this way. This dry February was an eye opener for anybody who believes we are likely to return to our normal climate. Remember the (RRR)  Ridiculously Resilient Ridge that has been parking it's self in our neighborhood and chasing all the storms north? That reappeared in February and dried the month out and elevated some temperatures into record territory!  It looks now like the rest of March will follow the same RRR pattern and thus El Niño fades into memory! NASA is reporting that February had global record-breaking temperatures by a stunning margin and warned of a 'climate emergency'.  In summary El Niño has produced welcome rain back into more normal range, however it did not generate quantities that the 1997-98 season produced. History tells us that a normal rainfall year is not dependent on  El Niño but after 4 drought years and finally a significant El Niño year and yet the rain fall is just average! So if we are now 15 years away from the next  El Niño does that mean we are looking at 15 years of sub-par rain, scary thought!


A remarkable companion to El Niño is the unusually high surf that has been pounding the California coast all winter.  The surf has been eroding the coast in spectacular fashion from Pacifica where 2 apartment buildings have been demolished, and in Miramar and Surfers Beach which are under going emergency repairs in an attempt to save the infrastructure.  In my next blog I will go into detail on coastal erosion and the effects of high surf!

King Tides Report January 21, 2016

El Niño Waves Pound Coast
Currently we are in the middle of the January King Tide event occurring 1/21/2016 thru 1/23/2016. During these events I monitor Miramar, Surfers Beach, Mavericks, and Pacifica, most notably around the Pacifica Pier.

Today at 7:52 am there was a 6.4 foot high tide. Barometric pressure was steady at 30.15 inchHg, wind was light, swells very small 2-3 feet. So today's King Tide was not very interesting due to poor conditions. However tomorrow looks like it could be very interesting on the coast. A significant storm is due in tonight and is predicted to carry on thru Friday morning at least. The surf report for Mavericks predicts 10-13 foot waves with 25-30 mph winds. High Tide will occur at 8:39 for Mavericks at about 6.4 feet.

The ocean has been more active during our  El Niño event than I've seen for many years. Recently there was very high surf that lasted for several days with spectacular wave action and damage along the coast. Beach Road in Pacifica is a street that runs parallel to the ocean around the Pacifica Pier and has been heavily damaged by the recent ocean assault and this has been widely reported in local news reports. Mirada Road, what's left of it,  is being battered on a daily basis and currently there is emergency repair work going on on the south end of the road. Mirada Road is no stranger to coastal retreat and destruction, years ago it stretched about a mile further up the coast near Surfers Beach. Constant retreat due to wave action has destroyed the portion of the road that stretched from Magellan ave to Surfers Beach. A picture of the remains of this road was featured as the cover of the book Living with the Changing California Coast! I'll be watching the action tomorrow which should be more exciting and dynamic than what was observed today.

Monster Waves in the Pacific.....

Wave Action Pacifica Pier
....hammer the California Coast! On December 11th and 12th a High Surf Advisory was issued for the California coast with waves recorded as high as 42 feet in the Pacific. Record rains pummeled Oregon and Washington causing mud slides and flooding. On Friday December 11th I traveled to Surfers Beach near Half Moon Bay to record the action at a 5.9 foot high tide. Construction work has been on-going at Surfers Beach to address the major erosion issue near highway 1.  

Surfer Beach 12/11/15
Although the action at Surfers Beach was exciting I heard reports that the surf was off the charts in Pacifica California. I was disappointed I had chosen Surfers Beach for my photo shoot when I heard the news of Pacifica. Since the best action is at high tide I had missed the window for Pacifica.  As luck would have it the High Surf Advisory continued into the next day 12/12/15 and I headed for Pacifica at high tide!

As soon as I arrived near the Pacifica Pier I knew I was in for a treat as many of the side streets leading to the pier were closed due to flooding. I had in tow 4 cameras, a Canon 7D2 with a 10-22 wide angle lens, an Olympus E-3 with a 50-200 zoom lens, a Canon 7D with a 400 prime lens and a Panasonic video camera, not to mention my IPhone 5 smart phone. Some of my past King Tide photos have been taken during King Tides in Pacifica and I have been drenched before in the excitement of shooting and being blindsided by a wave. I've sort of come to expect a drenching in these endeavors, kind of like taking a bullet for the team!

A Single Frame from the Animated GIF
I started filming with the video camera and got a 6 minute clip of the wave action pummeling the pier and surrounding streets. The video gets more exciting at the 3 minute mark and beyond! I then started shooting with the still cameras and thought I was in a fairly safe spot after observing the wave action for awhile. The animated GIF above tells what happened next, I was totally blindsided by the biggest wave of all. I was so absorbed in the action I did not perceive the enormity of the wave about to crash on to me. I guess being oblivious to my surrounding enabled me to continue shooting and catch the entire wave frame by frame until it blanketed me......wahoo!
There was much excitement in the area, everybody was enjoying the display and you could hear owes and awes as another spectacular wave crashed ashore! I shot enough frames of a young girl having a grand time dancing and Moon Walking to the surf undulations to create the animated GIF.
