Tour of the San Andreas Fault thru San Bernardino 

Growing up in the area, I never knew how many times I was on the fault or in the fault zone. This is fascinating stuff.

I really appreciate your hard work putting this together. I grew up in San Bernardino and Highland in the 1960s. I never realized how close we lived to the fault zone.

We lived on the fault in the Santa Cruz mountains during the 89 quake.. it was an unreal experience.. I’ll never forget the sound.

I travel from the continental plate to the pacific plate and back everyday. I’m surprised California doesn’t put a sign stating “ San Andreas Fault” 😊

My sister lived right on the San Andres fault for about 30 years or so. She went through a lot of scary temblors and I'm very happy that she's out of there before 'the big one!'

Watching this from riverside in the inland empire. Living on the edge

I live in the Verdemont Heights area, just one freeway exit east of Devore. I always knew I lived in the fault area, but never realized that I'm walking distance from the fault lines. My friends and I would ride our bikes over all the scarps and spurs in our area when we were kids. Even today as an adult I still take my motorcycle or go hiking in those areas. I attended CSUSB and Cajon High, which is across the street from the Uni. Rumor had it the library for CSUSB and the boy's locker room at Cajon were built right on the line. Watching this video, I can remember where on both of those campuses I can see evidence of the fault zone. A note on the erosion in the Devore area that you mentioned is commonly misconstrued as a scarp. There used to be a beautiful little KOA campground in that little canyon. My parents were friends with the managers and we used to ride our ATVs to visit them every weekend when I was small. A lovely little creek runs year round from there into a wash near my home on Palm Avenue nearby. As a result of The Old Fire in 2003 that left the entire mountain a burnt scar, there was a series of huge mud slides on Christmas day that year. Unfortunately, the KOA was completely wiped out and the managers of the campground were buried alive in the mud. My dad and I tried riding up there earlier this year on our motorcycles and it's a really rough trail now.

This is wonderful. I did my own tour of the San Andreas from Palm Springs to San Francisco in 2015. It was a lot of guess work and not nearly as comprehensive as what you have done. I really enjoyed it. Thank you. I will look at the rest of the series.

So glad I found this channel. Back around 1965 I gave my dad a book called “Earthquake Country” for Christmas. It was published by Sunset Magazine and showed many of the features of the San Andreas and associated faults around San Bernardino County. Now, as it happened, my dad was an inspector for the FHA, and one day was scheduled to look at some property that was going to be developed for tract housing. He thought the area (near Redlands) looked familiar so he checked the book when he got home. Yep. One of the faults went right through the development property. His recommendation was for the FHA to not OK loans for new houses there unless a geologist was consulted. The geologist recommended against development unless changes were made in the tract layout. That was about when Dad retired, so he never knew if the builder changed the tract plan, or just built it without FHA loans being available.

This video was so well put together and obviously required a ton of research 👏🏻

It would be interesting to see a similar series on the San Jacinto Fault. It has been more active than the San Andreas Fault South East of San Bernardino.

Having lived in Yucaipa most of my 70 years, I am well aware of the faults in my area. Something that you might be interested in, the original plans for the Greenspot dam was to be a lower dam that was a C shaped that would extend out towards the Highland area. It was going to be a recreational area. But the locals (me included) protested because the dam would passed over the fault(s) twice. SB County finally relented and built the dam that we have now. Here in Yucaipa, very few people that live here realize the fault is in the north part of town.

It is a very rare house-buyer who orders a geological report, much less read one and understand it, for the property they are to purchase. Not just faults, but flood zones in particular are often ignored.

These videos require a lot of research and lots of combined skills to put together. Very impressive! You deserve a lot more subscribers.

As an ex Riverside San Bernadine resident of 20 years I had forgotten that I had heard much of this from local media. Great stuff great job.

As you said, the San Jacinto fault is more active than the San Andreas fault. NE of the 210 and 215 junction is a large hill. It's about 200-300 feet above the surrounding plane. Little Mountain Dr and Ridge Line Dr are a couple of roads on this isolated large hill. I think that this hill is an inselberg, one of the largest in the area. I think that it was uplifted by the San Jacinto fault squeezing the land between it and the San Andreas.

240 views, 35 min. excellent explanation / map / visual tour. best I've seen. I posted this on a arrowhead page on fb. I expect there will be a uptick of views and responses. thanks for the great work.

I live in San Bernardino and this honestly is my everyday routes 😂 I never knew the San Andreas Fault was that close. What a beautiful educative video, this made me have more love for Sb.

Most of San Bernardino Valley College had to be rebuilt to accompany being on the San Jacinto fault zone. It cuts diagonally right through campus. I attended during remodeling. 2006-8. the slight hills make sense.

It was fascinating to learn about all of the little "signs" and "clues" (geologic features) that the San Andreas has left around the local landscape to let us know that it is here. Once you know what to look for, it is a bit hard to miss. For example, the long skinny parcels of "park" areas in some of these neighborhoods are actually just fault line that builders could not put homes on. Apparently many people have no clue that they have a fault in their backyard (literally), or directly under their structure. My anxiety has increased significantly after watching this. Ignorance is bliss!

Outstanding reporting and knowledge of details Thank you for this video .

I was in Highland in 87 and remember watching a small wave maybe 4 inches high flash across football field during small quake. Thought it pretty neat until I found myself in 89 Loma Preita …. That was terrifying and I was 90 miles from epicenter!

Really like the distinction you made between a fault line and fault zone. I'm a current Geophysics grad student at UCR and enjoyed how you paid close attention to detail when a lot of other people do not. I can say that everything you said here is accurate with one caveat: sag ponds: Not all sag ponds are spring feed. Most are actually created with a divergent step in the fault, as the fault is not a continuous line or zone. The divergent stepover causes the land between the two strands to create a depression where rain and snowmelt can collect. Just something to keep in mind when looking at sag ponds :)

Kinda interesting seeing my trail mentioned in this video. The Highland Natural Parkland Trailhead. I've walked all up and down that trail, there used to be old turn of the century earth movers, around the end of that trail, and an abandoned train car. Most of its gone now. Got lots of nice spots where its great to watch the sunrise. There's also spots where it overlooks a creek. Some locals even made a swimming hole in said creek. Great area, its where I went to clear my head.

Good video. I love going to locations like these to see geology in action. I've found that people shut off their brains when they're told anything like this about where they live. I've met several people who insisted Palos Verdes peninsula has no faults, making it 'safe' from earthquakes. One guy in Silverlake asked me about it, and as soon as I thought about it I realized his house was on the upperside of a very steep scarf right along his property line. It was on a short fault, so not much risk. When another friend just bought a house he woke me up to ask about faults in the area. His new house was in the foothills of the San Gabriels -- the street name sounded familiar. I was telling him about the faults and how far he was from the San Andreas as I brought his location up on the computer. As soon as I saw the nearby storm channel I remembered where I'd heard his street mentioned: John McPhee's The Control of Nature - in the section about flash floods. I suggested he not worry but consider sinking a steel pole in the backyard and making a treehouse for his kids - so in case of a flash flood they could take refuge. He never spoke to me again. As a teacher I was to teach students about earthquakes. So we looked out the window (we were on the 5th floor) at what we could see of the location of the Hollywood Fault. Later I was scolded. I was to make earthquakes relevant to students, but not scare them. They weren't scared.

Great video as usual. As a resident over the years of Palm Springs, Desert Hot Springs, Banning and now Hesperia, I have done lots of exploring on the fault. It is amusing that so many residents have no idea of how close they are to it. Thanks for the tour!

Wow this is scary! Living behind Walmart in San Bernardino and watching this is gnarly. I guess I just have to wait and see

This is meant in the kindest way. You sound very much like Huell Howser. And I can see him doing this kind of presentation. As a native Southern Californian I have experienced a goodly share of earthquakes. I till people that we don’t own land. We owe space and the land kind of shakes through. If you’re lucky enough to get to take a train ride through Cajon pass you can truly see California’s conveyor belt.

Excellent! What a fabulous endeavor to fly us over the fault. I may need to stay up late tonight and watch the entire series .... maybe tomorrow after turkey. Thank you for creating these informative videos.

I’m getting ready to do the tour. Thank you for doing all the work to help me on this journey

Developers didn’t think building houses on a fault line was a good idea? “Ya think?” But, overall one of the best videos I have seen on the subject! Keep up the great work. Enjoyed watching and learned things.

This is awesome. Thank you for this informational video.

Pretty cool hearing all my familiar cities names

Love these, thank you

Wow, this is very interesting. I live in East Highland right by the water reservoir near Highland Ave and Clover street.

Excellent, the previous video on the San Andreas pointed out Lone Pine Canyon and the nearly invisible road that you can pick up off 138 right near the 15. I took that gorgeous drive through Lone Pine Canyon past the ranch where the Earp's had stayed so many years ago. That road dumps you right into a residential district in WrightWood. A drive worth taking. Thank you.

The Fault that goes under the 215 and 10 freeway interchange also goes next to or under the National Orange Show which is now the Location of Several 100K plus attendance Concerts including "Escape". A Halloween Themed festival more popular than UC Santa Barbaras Halloween block party from the past. What would happen if that ruptured during a Festival? Hmm

Boy! Are they going to get a big surprise . Thanks for the video very interesting.

It's amazing that communities don't put up signs showing where the faults are located. Here in San Diego, we have "Fault Line Park" in downtown. It even has lines painted on the sidewalk to show you where the Rose Canyon Fault is located. At the north end of the park facing north, you can see that condos were built on either side of the fault with the fault being green space between them. Very interesting and entertaining video. Thanks for posting it. Looking forward to your next.

Very interesting. Thank you for the lovely tour.

Very interesting. Explains why San Bernardino is so affordable! I'm sure most of the nicer homes are engineered for this type of condition.

Great video, fascinating information, clearly presented & I like that you get directly into interesting information.

We bought a new house in Palmdale in 1993 and they had to disclose that it was built less than two miles away from the fault. Even as a kid I remember those documents. We played in the desert behind the tract of homes and there were HUGE fishers along the fault that crossed the desert, they were about 10’wide and about 1-3’ deep. Scary stuff. Ironically I had a neighbor that moved from Northridge to Palmdale because of the earthquake and bought they home on a fault line again 😢

This is such an amazing video! Thank you!💕❤

I have lived for the past 3 years near the Newberry Mem park. I had an emergency water, food cache in the back yard. But I have since had to move to a nearby rental. It's difficult to see the fault in this area as rich people in big houses are afraid of strangers and have restricted access as much as possible.

Thanks for the tour

this video scratches an itch in my brain soooooo well. my favorite youtube video ever.

Wow! I live in mentone, had no idea all this time how close the fault is!!! Great work, very informative!

FYI, correct pronunciation of JACINTO is "Ha SEEN To" (not Wa Sin To) and VALYERMO is "Val Yair Mo." If you're able to revise the audio, thanks. Great video!!! I live in the region and it's so important to know exactly where the San Andreas fault is!

Amazing video, the Elephant in the room so true!

i grew up about 1½ miles from the San Andreas Fault in San Bernardino. My wife grew up only 0.6 miles from it, and her brother bought a house within the fault zone.

I used to live in Riverside and I had no idea that the fault line ran through San Bernardino! Someone said Riverside sat on one of the fault lines' branches when we had a little shake of 4.8. We left right after that!

My goodness what information., Much needed. Knew about the fault coming thru San Bernardino county and parts of highland.

Great video and would love to see one done covering the Hemet San Jacinto area. Btw the J is pronounced hacinto not wacinto

I wish I could have seen you. I live on the fault zone at the top of Sepulveda Ave. And you just passed my house. Could have shown you a few things here. Good vid!

thank you for the great history and this great video....

Very scary...I just have to mention how clear the weather was the day you photographed this vlog. Unusually clear. Also sad I bet most people in this area of San Bernardino that live on top of the San Andreas fault haven't a clue they do. Doesn't that important information have to be disclosed at the time of purchase of the property or home?

good video, thanks for making it. i just hope many , that NEED to see this DO SEE it

You went right through where I grew up. I did know about the fault.

Gah!! I love this shit!! I should have been a geologist but I'm soooo bad at math. Thank you for this endlessly fascinating series.

Another excellent video!

Thank you very much for sharing this. You know what would be cool? Placing geocaches along those stops as part of an educational tour. If I lived closer I would place them myself. Instead, I live in another geologically significant area of California; Ridgecrest. Not quite as interesting as the San Andreas, but there is the nearby Garlock fault and the network of faults that make up the Eastern Shear Zone which was responsible for the 6.4 and 7.1 earthquakes we had in 2019. Unfortunately a lot of that fault mapping is on the China Lake Naval base property. There is still enough to look at outside of the base. The best indicator of the fault networks out here is the abandoned gold mines. It seemd the early miners knew more about the faults than the geologists of the day.

As a local to the area in this video... San Jacinto .. the J is pronounced as a H in spamish and not a W ... so it would be San J (H)acinto....

At 29:21 you can see where the mountain range split and is sliding northwest. The SG mtns are sliding to the NW. The SG and SB mtns were a single mountain range a long time ago.

This was really great! Can you do a video of the San Andreas through the Coachella Valley?

I'm following along with you, on Google Earth. It's amazing how many quarries, mines and gravel pits there are along this fault line. Just how overdue are we? Great tour. Thank you. Those people have no idea, they are on a fault line? Wow.

Amazing videos, Thank You!

Wow! I lived and worked in Highland for 12yrs and never knew I was living on a time bomb!! I felt many small quake's nothing big thank God!

I was looking at areas of Desert Hot Springs, about 8 miles north of Palm springs, and the fault line goes right through neighborhoods with some homes that must be on top of it

An interesting video, as always. It seems that a lot of people have no idea of their proximity to the fault. I've never experienced an earthquake. Believe it or not, we sometimes get small ones here in NJ. There is a noise like a sonic boom from a jet, but no shaking to speak of.

Wowwww.. impressive development on one of America's predicted great mega thrust earthquakes. I hope my friend Tom is all safe N sound down there.

I love all your videos. ESPECIALLY San Andreas. Picked some books to get more study material. Could you share what literature you use please. Planning my trip to salton sea. Mud pots!!!

This is a very interesting tour. One thing of particular interest to me is the Indian casino and whether the new Highrise hotel was built directly on top of the San Andreas. Can anyone answer whether the fault line passes directly beneath the hotel ?

I always knew the San Andreas Fault was near us but I didn't know it was that close. And this video is recent😁

Very interesting. 😊

In the late 90's @ Wallace creek. I dug a trench for geologists on the fault line. Near soda lake road.

I really love this video with its full explanation of the San Andres fault. I usually drive on freeways 210, 215, 10, 15 I love the vow of the mountains and everything around this area. I hope one day earthquake will not hit while I am driving around.

This was an excellent video.

It is crazy that the City of Desert Hot Springs allowed the developer to build the house I bought back in 2005. I found out afterward it is directly on top of the fault zone and its entire area is predicted to liquefy if and when a major earthquake happens.It is the top house on (68887 Panorama Drive)

I'm not even from California but I made it a part of my research (before I moved here) to know where the fault lines are in Southern California, and up north beyond S.F.. There is a site that shows EXACTLY where the line is at. It's a red line that you can zoom all the way down as close as the satellite images will allow you to, which is about 300 to 500 feet above the land. Close enough to get an idea if your house is exactly on the line. Here in the Palm Springs area, specifically in the northern parts of Indio and especially through Desert Hot Springs, you can see the line go right through peoples houses! Sitting right on top of the most frightening fault line in California. Imagine sitting watching TV and suddenly the television part of the living room instantly shifts to the left while you shift to the right, ripping your house right in half. You'd be lucky not to be instantly killed and if somehow you survive, imagine what a scary experience that would be? I can tell you that when I tell people we are only a few miles from the fault line down here in East Palm Springs region? Their faces are shocked. Here are some facts as of right now. The San Andreas fault line is WAY overdue to have its next major eruption. It is deemed to happen at any moment, any day. The rip will be instant, approximately a 30 foot rip within one second. Anyone on this line, or near it will feel it first as the force will rip across the entire region on both sides of the continent. There will be a horrible roar and no one will avoid being affected by this major shake. Those next to the line will not hear a pre-rumble as the rumble comes from the rip itself. They will get the worst of the initial rip. The rip will be instant, with zero warning. Depending how a home is built, a lot of structures lower walls will be thrown out from underneath them and the roofs will collapse right on top of whoever, whatever is inside of the home. This is how powerful this quake will be. Being from the midwest, I cannot believe the California government has allowed ANY homes or structures to be built even within a thousand feet of this line.

Really enjoyed this geological tour. Do you have a similar one for any fault line near the CA Aqueduct Cascades, off the 5, near the 210?

I live below Interstate 10 in South Louisiana and when were having our house built we had to have a geological survey done to determine if we needed to have Flood Insurance.

22:50 - Orange St. / Holly Circle Dr. is a good example of the "microclimate" of Southern California. In one turn, you’re in the desert, in the next turn, you’re in a rainforest!

I’m loving this series! Not only is this video right in my back yard, but I’m also planning a Route 66 tour very soon. I’m curious about the narration software - I wonder why it inaccurately pronounces San Jacinto, “WAH-cinto”, rather than the proper “HAH-cinto”. 🤔

I lived in granada hills for the Sylmar quake. I was 12. we had to evacuate for a week or two because of damage to Van Norman dam. then I lived in Palmdale for the Northridge quake. but my sister lived in Reseda at the time. scarey!!!

I have friends who live in Cathedral City. I love visiting them because their house is like a resort but the fault is literally 5 miles from their backyard. I used to live with them in Studio City when the Northridge earthquake occured in 1994 and I was almost killed. I've lived in NY since 1998 but I always worry about all my friends in California due to the quake threat.

Interesting! 👽

a GPX file of these locations is epically appreciated- wish more people would do it

Ignorance is bliss. The property owners tell everyone that they have mountainside homes with stunning views, neighborhood ponds and natural green spaces. Our neighborhoods are a great investment and perfect place to safely raise a family. Never mind my fence line having an offset and constantly needing repair. Sad thing is even though I’m a hick from Kansan I’ve known and traced the San Andreas and know the signs of it. All the way to Pacifica at the entrance to the San Francisco Bay and out into the Pacific Ocean. Same signs and features are presented.

Thanks again for a wonderful video lesson. Like shorting a stock price we can get some addresses and short the houses and insurance, 😆 🤣.

Right in my back yard the Lytle Creek wash.

Would have been extra special if you could have shown us how Wrightwood and Oak Glen were probably right next to each other many millennia ago.

Excellent video!! Very informative..as a Yucaipa resident, I've always know if this section of the fault let's lose Oak Glenn, and Yucaipa will be especially affected by severe damage, possibly near completely destroyed. And just an FYI , the San Jacinto mountains are pronounced HUH CINTO HUHCINTO, the j is silent. Ive been hearing all my life having been born here about the big one is coming.....I'm 63 now hasn't happened. Hoping it wont. But this is totally out of our hands.

It's funny how none of any park signs mention that they are right on the fault line,however up in wrightwood visitors center, someone did build a big model of the mountains your in,showing the fault lines

I live in Rosena Ranch and my best friend lives in Devore =D

Such a cool video!

I live on the fault and this doc highlights my neighborhood. In one of the early pictures it shows a park with houses above it. When they built those homes we went to the opening and I asked the Realtors how are they disclosing to potential buyers about these homes being on the fault, my answer was ‘What are you talking about”?

Just saw where our house is. At the base of the San Bernardino mountains an exit next to Devore😖

Almost 30 years ago we took a field trip to the San Andreas fault line. We walked there from Hillside Elementary School. Fast forward to today, I still live on the fault line and don’t care 🤷‍♂️

I live in Fontana…every time I look out my kitchen window, I see those mountains and think about how the SA Fault is right there
