San Andreas Fault Tour on the San Francisco Peninsula

[@travelispassionromania1994]

Keep doing great on your presentations. I love California and your videos are informative, educational and rewarding.

[@BackRoadsWest1]

I will! You're welcome and thanks for commenting. Hopefully you found our other video tours on the SA fault.

[@angelasepi657]

Thank you so much. I totally enjoyed your series on the San andreas fault. Very well done.

[@jamesthompson3099]

I just happened to trip over this video. What a great tour! I spent nearly 40 years in the area before moving to the midwest for my job. All my teen and young adult years included. Boy does this bring back memories! Many thanks.

You can see the fault in Portola Valley at Coal mine ridge off Alpine rd.. Several Sag ponds and visible parallel valleys. And trenches dug by USGS. Also can see it at Huddart park along Union creek.

Thank you for putting this together. I did this twice now, once during pandemic and another one today. Brought back a lot of memories of my first drive. And this time I added more visits at Woodside as a starting point. Very nice sunny day, nice weather, is hot but perfectly windy. Your video is educational. Lived here all my life, and only yours give me a first hand earthquake drive through the bay area. 👍

All of this area was my home. I moved 5 years ago. Miss Home. Makes me sad

[@radarnutvfr6021]

Man, what a trip down memory lane! I grew up in this area but moved shortly after high school. It was neat to see places I used to know quite well. I have always loved geology and earthquakes and made it a point to know where the main fault lines in the Bay Area ran. As a little kid I would try to see the SA fault whenever we crossed the Crystal Springs Reservoirs on the way to my grandparents. Experiencing the '89 Loma Prieta quake was quite the ride, the quake sloshed a friend out of our high school pool during a water polo match. Great visual info, thanks for the video!

[@BackRoadsWest1]

Thanks for your comment!

[@magicunicorn6535]

I lived in Woodside during that quake. I was outdoors in the front yard when it struck, and it was amazing to see the ground rolling all around, and trees whipping back and forth. Afterward I ran into the back yard to look at the pool, and the surf was definitely UP!

[@edwardsbarbara25]

[@wulf3345]

I grew up in Portola Valley. The fault went through the playground of PV school and the orchard next door showed that part of it had shifted rows of trees during the 06 quake. The fault follows Sand Hill road and Canada Road until it gets to reservoir.

[@dvferyance]

In San Bernardino there is a park and a playground right on top of the fault. It's beyond me why that would be allowed.

[@rubensanchez1797]

great video & thumb up ...

[@magicunicorn6535]

I used to live in several towns on the Peninsula on or near the San Andreas fault line. In addition to the large, easy-to-see features in this video, if you know where to look and what to look for, there are many hidden places in Palo Alto, Portola Valley and Woodside where the fault line is visible. There's a sag pond next to a stables where Portola Rd. becomes Sand Hill Road. On gated trails in Woodside, more sag ponds are visible on private property. When I lived in Woodside, a short walk west of Mountain Home Rd. took me down the eastern escarpment of the fault towards a portion of Woodside Rd. that runs within the fault, before turning up into the hills west of it. Wunderlich County Park is located on the western fault escarpment. When I lived in Portola Valley, our house was also on the western escarpment. I would laugh when the owner of the house would proclaim, "The fault doesn't run under the HOUSE, silly! It runs under the LAWN!" Haha! Yeah, right. As if that was so much safer! Hiking trails in and near Huddart Park cross more of the fault line, but it's hard to see because it's in dense redwood forest. Another place that's great for exploring the fault line is in Southern Calif. in Wrightwood, near the Holiday Hill Ski area. If you're riding up the chairlift from the lodge to the top of the ski hill, if you turn around and look backward, you can see the fault line very clearly running along the valley below. The Valyermo and Devil's Punchbowl areas nearby are great places to see traces of the fault by driving and hiking.

[@TheOgrande]

Crazy that I drive a lot on the 280 and never knew I was driving on the San Andreas Fault.

[@BackRoadsWest1]

Now you know!

[@ksoman953]

W O W. Love this!

[@woodlandsfarm]

Great video, beautiful scenes, will definitely make a trip there to see the fault line physically, meanwhile have to settle for a virtual trip.

[@BackRoadsWest1]

Great! Thanks for commenting.

[@sifridbassoon]

Years ago I lived in San Mateo (well, Foster City actually) and would often go over to Crystal Springs resevoir. There is an amazing hike/bike trail that runs through the valley. At one point, there was a small land bridge that separated San Andreas lake and Crystal Springs, and there was a small marker showing where the fault ran. I would take my visitors there where they could stand with one foot on the Pacific Plate and the other foot on the North American Plate.

[@ShonnMorris]

What's interesting is that there is also a Skyline Boulevard above the Hayward Fault in Oakland.

[@emmapeel1075]

This was so very interesting to me , a former Buffalonian ! My brother moved to CA in the '90s and for the last couple of years has been living in Sacramento.

[@lohphat]

Also of note, the Spanish expedition lead by Portola discovered SF bay by land in 1769 by standing near the same ridge you’re on as they missed the inlet due to fog. There is a marker where the landing party is said to have first seen the bay thinking it was an inland lake. They didn’t sail into the bay until Aug 5 1775 in a later expedition.

[@miamonmiller3967]

I just read that the San Andreas Fault was given that name by Andrew Lawson, a geology professor at UC Berkeley.who, in 1895, discovered the fault when exploring the San Andreas Laguna located in the linear valley you described in the video.

[@BackRoadsWest1]

Thanks for commenting, because now I'll have to lookup Mr. Lawson and read about him. Cool!

[@miamonmiller3967]

@@BackRoadsWest1 You're more than welcome. I was interested in why the fault was called San Andreas (in English, Saint Andrew) and came across his name. Since his first name was Andrew, that was a mighty cool coincidence as well.

[@lisalee2885]

I have to say that I have watched 2 other videos showing and explaining. This one really ROCKS!!! No pun intended 😁 Really Well done😄🌸 Now take us from Palo Alto to Los Angeles.....Please😆🙏😆🙏

[@oldkingcole6147]

Really Enjoyed this video. It puts the whole SA Fault /earthquake situation in perspective. As young CANADIANS, we visited SF in the 1970's ...all pumped up thinking there might be an earthquake while we were there...lol But now, looking at the facts, I surely wouldn't wanna be trying to sleep at night in any of those communities built up directly over the fault. For that matter, I think it would be on my mind even in the daytime if I lived there. The Big one is due & I can't believe how much is built up over the fault zone!.... Sleep well!...cheers

[@mobility63]

I live in Cotati, in Sonoma county. The SA fault is 31 miles west, while the Rogers Creek fault which is the northern extension of the Hayward fault is 12 miles to the east. Lived here since I was a kid and have felt 5 earthquakes in the past 45 years. The largest of course was the 7.1 Loma Prieta in 1989 and the 6.1 Napa in 2014. The only damage was a broken water pipe

[@neptunedawn7121]

So the Crystal Reservoir is a big sag pond?

[@BackRoadsWest1]

No and yes. No, it's now a reservoir. Yes, it was a sag pond: a low spot caused by the fault where water collected, plus the fault blocked spring water that went to the surface. Since the low spot was already there, it was a great place to make it bigger to store water, which it is today. All along the fault, humans took advantage of sag ponds, which already existed, to store water.

[@lohphat]

You can visit the Crystal Springs “water temple” where the Hetch Hetchy pipeline empties into the reservoir.

[@scottcass4243]

That's the Pulgas water temple. We partied their as kids.

[@LuckyBaldwin777]

@@scottcass4243 I loved to go there as a kid. Stopped there about 10 years ago and the water temple was still there, but the water was gone. BIG disappointment

Can you eventually do a tour of the other faults in California like the hayward fault. I find these videos fascinating to watch seeing as my part of the world doesn’t have these types of features.

[@BackRoadsWest1]

I live in Utah and don't make it out to the Bay Area often. One tour I would like to do is following the fault north from the Golden Gate thru Pt Reyes. I don't know much about the Hayward or Calaveras Faults. For now, enjoy our tour of Southwest Utah geology: kzbin.info/www/bejne/b4XJo6Olbpmpgbs

[@RedAndGoldF8ful]

@@BackRoadsWest1hope you do a video at PT Reyes one day. It is SO pretty there (great places to eat along the way!).

[@lohphat]

Linguistically the way to distinguish between an northern and southern Californian is the use of definite articles with highway names. In SoCal it’s “the___” while in NorCal it’s “highway ___” without the article. So while in NorCal you should have said “highway 280” or just “280” as in “take 280 north until...” I’m originally from SoCal but lived in SF for 20 years. I was weird the first few months until I adapted.

[@ziggy149]

In Michigan we say "the ___" as well.

[@xmo552]

I guess... "Hella" is a norcal slang

[@popstarrocker420]

Nice info 💕

[@iluvbiggirlz420]

So this week be ground zero someday huh? I never heard of the Hayward Faults. It looks like the lands on the inside of both fault lines could slide off into the ocean. Maybe that's how that opening is like that. Like millions of years ago, it wasn't that wide, and pieces fell in over the years to how it is now.

[@BackRoadsWest1]

They won't slide off into the ocean - at least no during our lifetimes - plus it will occur vvvveeerrrrrryyyyy slowly.

[@user-zd6tq3xh4s]

Excellent👍🏻😉

[@BackRoadsWest1]

Thank you 👍

[@lsharon2175]

Houses and businesses are built right on top of the fault line. Is the land cheaper there?

[@RedAndGoldF8ful]

You would think that “land is cheaper on or along a fault”, but nope, anything here is expensive. People ignore the probability, with “wont happen to me, and if it does, worry about it then” attitude.

[@68camarobsk]

I’d like to see Where the Faultline runs through San Jose from highway 92& 280 south towards Gilroy I live in San Jose California don’t see a video covering it

[@BackRoadsWest1]

The San Andreas runs parallel and west of I-280 in the mountains and crosses SR 17 near Redwood Estates and to Loma Prieta. Google a geologic map of Santa Clara County and they usually plot the faults. If not, buy yourself a copy of Gaia GPS, turn on the geology layer, and you'll see the faults. www.gaiagps.com/discounts/?fp_ref=backroadswest

[@sharon94503]

The evidence at Stanford University's stadium is extraordinary. I live 30 miles North of San Francisco.

[@glendabarton1914]

I lived in San Francisco during the Loma Prieta. Only big one Ive gone through and thats not considered big, not like 1906. That wasn't even that big, it was largely the fire that killed people. We're used to living with that threat. Everyone is in danger from clinate change-induced disasters these days.

[@jeannehathaway5462]

Does the Hayward Fault also move lateral? The San Andreas fault line had almost a stair step shape in the area you showed. How does it move lateral at the corners?

[@BackRoadsWest1]

Since the Hayward is a branch of the San Andreas, it moves the same. Not sure what it does at the corners.

[@LuckyBaldwin777]

Funny how you didn't even check out the segment at San Andreas Lake. After the 1906 SF earthquake, scientists looked for the cause. They first discovered the fault at San Andreas Lake and named the fault after the lake. Camp Sawyer road goes right through there. When I was a kid, it was a dirt road you could drive, now it's a paved bike trail

Earthquakes are associated with the sun-earth magnetosphere that is becoming increasingly activated as part of the effects of the 12, 000-year micronova cycle that is now beginning, as noted by north and south magnetic poles on the move toward Sumatra and Java which will become the new Arctic Circle. 12,500-years ago 8/10 of species populations became extinct as the result of the Gothenburg event. The effect was greatest in the Americas, but This will effect greater damage in Eurasia. this time. Volcanoes and a world-wide flood will also accompany this current cataclysm. Humanity has survived at ;east 7 of these events, so we are survivors, if we are ready and prepared, My book, "Surviving the Micronova: A Train Is on the Tracks covering this in greater detail is available to help.
