The Mystery of Lost Lake of the Cajon Pass




It is not known to many people, but it is still possible to use the old highway up through a portion of the Cajon Pass. Present day highway 15 runs well above old 395 and Historic Route Highway 66. Such rustic areas as Blue Cut and Halls Ranch (Yes my Family again), and Sullivan's Curve still exist.

As you drive up the badly surfaced road from Devore (Use the Kenwood Exit from the Northbound 15 and make a left, pass under the 15 and then make a right on Cajon Blvd [old 395 & route 66]) you notice that for the most part you are driving on what would be the southbound lanes of the old 4 lane highway. As you come around the curve at Blue Cut you notice that there is now a mountain sitting over the right-hand lanes into the center divider. You might think that this is ample proof that the San Andreas Fault zone is alive and moving. But you would be wrong. It is actually the San Jacinto Fault Zone that straddles the highway. The San Andreas is still one mile ahead.
Two Faults zones so close together and visible? As you proceed north you notice that the entire area between the faults is moving to the north and at different speeds. Only 2 or 3 inches a year, but they are moving. So much so, that railroad crews from both the Union Pacific and Burlington Northern Santa Fe, have to go out twice a year and reset the tracks. Otherwise, the train tracks would bend out of shape, just like old 395 has.

As you proceed, you will see a sign that says 'Lost Lake'. It also says private road so most people ignore it and just keep heading up towards Sullivan's Curve. Sullivan's Curve by the way, is a favorite Train Watcher area and has also been the scene of several major train accidents over the years. The best way to get into this area is to exit highway 15 at Cleghorn Pass Road, make a left under the freeway if you are going north bound that is and then make a right on the first roadway you see. This will take you back to a triple track bypass area, a small yard, and the beginning of the lower end of Sullivan's Curve.

But if you take the time to make the left turn onto the dirt road and cross the triple set of tracks that tend to hide it's route, you eventually find a quiet little area that should not exist. For there are no streams, creeks or rivers that feed into Lost Lake. The water seeps up from beneath the ground. A direct result of two major earthquake faults zones passing within a half mile of each other.

Some say that Lost Lake has no bottom, that it feeds directly from the center of the earth. The water is also very cold, below freezing even in summer time. Fire crews have used its water supply to help fight fires, and they have never noticed a drop in water levels. It always stays the same, even in heavy rain seasons. And snow fall has no effect on it. But it has never frozen either.

Lost Lake is surrounded by lush grassy vegetation, some what like what you might see back in Kentucky or Tennessee. In fact Kentucky Blue Grass grows all around the lake.

As you drive further into the narrow valley you realize that both fault zones are coming together. All of a sudden you run into a wall of a mountain that blocks your way. You can climb up this 500 foot high rock fall and look out over the valley you have just passed through. To the northwest are the 10,000 peaks of Mt Baldy, Cracka Ridge and the Mountain High Ski area. As you hike through the area you become aware of how insignificant you are amongst the grander of the Fault Zones, the Mountains and the trees.

Lost Lake

My family & I used to go to Lost Lake a lot! We camped and swam. We bring our buggies or ATVs. There was some pretty great places to ride the trails and go down to the creek and play in the water, it was safe for the family to go to. That was in the 80's, and very early 90's. We went back later on, and it was fenced off with a parking lot - you could no longer drive down to the lake. There were places just past that we had 'heard' that bikers went, but never really saw a big group, but some there still, along with us. Our friends would all go here also with ATVs, it was a blast. I know now that along the old highway, at least before we moved to AZ in 2005, that men would meet up there for 'clandestine' meetings. It was a great place to go to around there quite a few years ago. I think the worse I ever saw there was a mud-wrestling competition by some semi-nude girls on the far side of the lake. LOL.

Re: The Mystery of Lost Lake of the Cajon Pass

I was at lost lake about a month ago and the gate was closed. Everybody was parked on the side road and I couldn't find parking so I decided to take the family to the creek below. We were walking down that brushy trail that leads to the creek and there and behold were a couple faggets going at it!! My kids saw that and I got pissed and told them to take their homo shit somewhere else!!

Re: The Mystery of Lost Lake of the Cajon Pass

I agree something should be done! I used to go there a lot, but then the gays started gathering there more and more until I just quit going. What really pissed me off was when I returned to my car one day, there was a flyer on my window reading "Are you gay, curious? Be here at 8PM!" Maybe I should have shown up... Guess I'll never "know"! (LOL)

Maybe I'll invest in a drone, paint it up with the Sheriff's logo, and buzz the "hot" zones!
I'm sure THAT video would go viral real quick!

Re: The Mystery of Lost Lake of the Cajon Pass

Ok, this is official. Last week the USGS was at the lake doing surveys and has listed the lake at an 8ft. maximum depth. The lack of rain and snow runoff are depleting the aquifer. The width, from north to south, is approx. 225ft. and the breadth, from east to west is just shy of 50ft. The water level has dropped approx. 8ft. within just the last year. Fishing has been slow as the drop in the water level has given the fish more to feed on than they can actually eat plus the fact that all the pigs, I mean visitors, have polluted the water with trash of all sorts...cans, bottles,(broken and whole),paper, plastic, diapers, graffiti, etc., etc. There are trash cans for your convenience to dispose of your trash as you leave but people find it to hard to pick up after themselves. One can only imagine what there homes look like.
If the forest service decided to close the lake to the general public because of the amount of trash left behind, I wouldn't blame them one bit.
Well, if we don't get enough rain soon to replenish the aquifer to a lake sustaining level then this little gem will soon become a stinky algae trap with no fish but then maybe we can at least get all the trash out of the area.
Enjoy it while it lasts because at this rate it won't be but a memory within approx. 1 1/2 to 2 years, if that.

I've heard that road is a paradise for that activity!

Re: The Mystery of Lost Lake of the Cajon Pass

I finlally got to lost lake I've been told about it my whole childhood life and had to go check it out for myself if if was really true what my family had said. They spent months up at lost lake back in the late 50 early 60 and went every summer after that until the 80. I toke me my husband and my kids we were summing only on shore but we for there at like 5 pm and the water was great just right temp. We were there 30 mins when my husband was being bit on the toe by a black fish with fins that were like spikes so we move closer to shore and water started coming in cold from the bottom for some reasion but it was a good way to cool off and I also drove down drit road and lost of people live on that road and it beautiful to me all natrial living in the fault line.whele we wer at the lake I smelled suffer smell mixed with wet weeds and fish

Re: The Mystery of Lost Lake of the Cajon Pass

After reading some of the comments here, I realize how some of these folks are just full of shit.
The lake is not bottomless nor is it 300ft. deep. It is approximately 25ft. deep at he deepest and is fed by a break in the fault, no more no less.
As for the faggots that cruise the area on the way to the turn-off, I think the county should throw the money into whatever resources it takes to get them out of their. I moved back to so cal in 2011 and got my gold pan and stuff and headed up there to the area where the blue cut plaque is. I used to go panning and dredging in the early 90's with my friends and my kids.
As I walked down the trail that I used to use back then, I was panning when behind me and off to the side was a dude whacking his meat. I told him to get the f#@* out of their before I kicked his ass and he left. After a few hours of no luck I walked back up and saw a dozen or more vehicles with only single guys in them, that's when I realized that this place had become a faggot cruise spot. I damn sure ain't happy about this and something should be done...now!!
As for lost lake, their are largemouth bass, crappie, bluegill and I hear, catfish. I've seen bass taken but nothing else. Nice place to visit for early morning fishing but this place gets too crowded during the summer with people who like leaving there trash laying there for someone else to pick up.

Re: The Mystery of Lost Lake of the Cajon Pass

Hello there, I know for a fact that Lost Lake is NOT 25ft deep. I have been there when driver went down in it to see how deep it was but got to scared at 25ft & came back up. They have not gone all the way to the bottom.

Lost Lake

Alright your correct & I am not ! Thanks for your information.I Greatly appreciate it.

Cajon Pass Lost Lake

Hello back. I hate to disagree with you but I was there just yesterday fishin for bass and was talking with a ranger who said that another dive was recently performed for the purpose of finding out why the water level is declining at an alarming rate. His most recent info. is that the depth is now at about 12ft. The lake at this rate may cease to exist in as little as 2 years according to them. Could this be an indication that the water table in this portion of the states aquifer being depleted with the lack of snow runoff and rain? Too bad, lost lake is a nice quick getaway for some stress relieving fishin.

Re: Cajon Pass Lost Lake

I dove down way deeper than 12 feet and alot deeper than 25 feet so try again liars im living proof that with one breath and goggles I could not reach the bottom. So tell me again how deep.

Re: Cajon Pass Lost Lake

what type of measuring device were you using to know that you were "alot deeper than 25 feet" ?
I highly doubt you could go much deeper than 15 feet unassisted and on only one breath.. That is however only my opinion, but if you did not have any way to accurately measure how deep you went, your claim is also nothing more than an opinion

Re: Cajon Pass Lost Lake

Well im no Michal Phelps but I'm a great swimmer and with goggles on couldn't see no bottom.you should try and see how far and what you see. And then post something just saying

Re: Cajon Pass Lost Lake

So, in other words, you have no idea how deep you really were.
I would also suspect that in any even semi-dirty lake, once you are deeper than 10 or 11 feet, the visibility would drop to inches. So even if you made it to 15 feet, the bottom could have been 2 inches from your fingers and you would not be able to see it.
I don't need to try and do it myself because the guy above already posted that the rangers did it for us, and they measured it, so I'm going with what they came up with.

Re: Cajon Pass Lost Lake

You shouldn't take their word if you read it correctly the ranger didn't dive themselves. All im saying you should grab a some goggles swim to the middle and see how far u can go. A decent swimmer can easily go deeper than 15ft.living proof.

Re: Cajon Pass Lost Lake

I been going to lost lake for over 20 years and yeah it has a bottom but it all depends on how long you could ur breath in and specially after 20 feet with no oxygen bottle u pretty much give up and re-surface.

Re: The Mystery of Lost Lake of the Cajon Pass

I visited lost lake in the late 80"s stayed the night with a bunch of friends. A man scuba dived with a rope about 250 feet long.that rope went about half way and the man returned.he says that he has never had such an spooky feeling ever in his life but He also stated that there was caves below that He was afraid to enter.so I'm a believer that somewhere it is bottom less.at night some pretty freaky people came out. We were told that they worshiped Satan. DOES ANY BODY EXPERIENCE THAT.IT WAS A CRAZY NIGHT

Re: The Mystery of Lost Lake of the Cajon Pass

my dad supposedly drowned and died in that lake in the 80's did u ever hear about that I been looking for the store sreaching everthing and nothing comes up plz let me know if u heard about this

drownings in Lost Lake

A lot of people have died in that lake over the years. I think in that last few years a man from L.A drowned, before that a little girl, I heard a few murders also! My brother in law almost drowned a couple years ago I almost drowned trying to save him!!

Re: drownings in Lost Lake

I heard my old neighbor Rick Glass from Ontario was murdered there years ago. They tried to make it look like suicide. Drug deal gone bad :-(

Re: The Mystery of Lost Lake of the Cajon Pass

Yeah. I know the feeling... Like you're being "watched". ONE SPOOKY PLACE!

Re: The Mystery of Lost Lake of the Cajon Pass

The people there are cannibals and it was called The Colony

Lost Lake in Cajon Pass

How safe is Lost Lake for a visit and for fishing nowadays?

Re: The Mystery of Lost Lake of the Cajon Pass

Actually, there are reports of the bodies of clones at the bottom of the lake. It should be investigated forthwith.

Lost Lake in the Cajon Pass

if you you look at it from googlearth stand point. Its obvious that basin was full of water at one time.

Lost Lake

A biker club owns a house on Swarthout Canyon Rd. The mailbox gives them away. Down the road a bit is a Korean 24/7 Prayer Ministry. Been there to fast and Pray after I was rescued from SATAN. LOL Really... Some of us from Muscoy used to go up there from time to time to chill, etc. Ive seen some interesting people here before.

Lost Lake in Cajon Pass

As far as finding the depth of Lost Lake, it depends at what point you probe. I dove pretty deep in 2001 with no bottom in site. The warning is that there is thick undergrowth that one could get tangled up in. If you panic and thrash, it could keep you underwater. Could be the answer to questionable drownings.

Lost Lake in Cajon Pass

As children, my parents took us up to Lost Lake, hiking around the mountains, then a swim in the lake, we all had lots of fun, yes there was an returnees about it. You hear so many weird stories, my parents were childhood friends, they used to go to Lost Lake, and ditched school, that's where they went, they took us their as kids. I took my kids there, now its really gotten bad, too many dangers lurking there. Not for me anymore.

Lost Lake near Interstate 15

I grew up in Lytle Creek. I 've been to Lost Lake many times. It is a mysterious place indeed. I used to ride motorcycles around the lake in the late 70's. There were many trails at that time. I grew up seeing the bikers partying and raising hell out there. I've swam there a lot and heard a lot of stories about deaths and drownings at the lake and that it was bottomless.
I remeber as a boy someone built a sort of big long wooden diving board on the up canyon end of the lake. It was only their for maybe a year. Does anyone else remeber that?

Lost Lake in Cajon Pass

In the summer of 1961 my husband, his friend my cousin and myself decided to go spear fishing at night in Lost Lake (by Cajon Pass CA). My husband and his friend went underwater and speared orangish fish which we took home cleaned and ate.

They found the lake not to be bottomless they snorkeled around the whole lake with underwater lights. I hate to burst peoples bubbles... I am sure there are fissures which supply it with water though. The worst thing that happened to us at Lost Lake was that some dummies were shooting guns randomly and almost shot us one day.

We used to drive the back roads there with our dune buggies quite a bit.

Cajon Pass Lost Lake

i have been there once in my life and will never go back.the feeling i got when i crossed that river and felt that bone chilling cold water is a feelinf i can not explain. Lost Lake yea wont be goin back there again

Lost Lake in Cajon Pass

I grew up in Fontana in the 90's and have gone to Lost Lake for more than 15 years.

A good friend and I used to take our kids there and meet up in our classic v-dubs. I really love this lake however I hate the fact that some people disrespect it by leaving their trash and diapers and fish hooks in the water. If you go there please be sure to buy the nature adventure pass first (this pays for the tables and for the workers to clean up after those who trash the lake) for $5 or you risk getting a $60 fine!
Also BEWARE that the train viewpoint turnout on old route 66 that leads down the the creek is frequented by truck drivers, homosexuals and perverts looking to "hook-up" with one another, and not to allow your children to explore this area without adult supervision! Back in the summer of "08 my friend and I were followed by a creepy fat latino pervert in a white large chevy truck and he attempted to expose himself to us and our kids! Just be careful and If you are like me, young cute adventuring Mom, you should always carry a knife with you AT ALL TIMES!

Have fun and good luck!

Re: Lost Lake in Cajon Pass

OMG! I noticed the many male homosexuals also. They are totally prostituting and drug dealing!!! But I have noticed they are close to creek not this lake? Was the experiance at the actual lake?

Re: Lost Lake in Cajon Pass

No, it wasn't at the lake, it was at the creek BUT, I have seen sexual things happen at the lake parking lot, the used condoms on the ground give it away. Very sad. What ever happened to ,'get a room'?

Re: Lost Lake in Cajon Pass

The creepy pervert incident was at the lake in the parking lot! We had seen this man before and recognized his vehicle, he followed us in it more than once. The first time we saw him he was swimming in the lake in tighty-whiteys so we nick-named him "The Panty-Man"! BEWARE THE FREAKY PANTY-MEN!!!

Re: Lost Lake in Cajon Pass

You really have to watch your kids around the creek there is a lot of homosexual activitys and drugs around the creek area. That area is known for homosexual hook ups!!

Lost Lake

Yes, Lost Lake is a sag pond that filled up with water after the fort tejon quake of 1857. Totally bitchen area with so much history. I can understand exactly what many of you have said about a creepy feeling around the lake, an it being so dark. be careful all around this area. Many people have been reported missing from this area since the early 70s.. numerous bodies have been pulled from this lake. definiately a cool place. the lake sits directly on the san andreas fault. This area is constantly moving. The train tracks nearby are adjusted twice a year to keep the trains from derailing. From Lytle creek up through the cajon pass there are many hidden treasures. the mormen trail.. another great place so rich in history.

Lost Lake of the Cajon Pass

Urban legend. It is not bottomless. Lost Lake water supply is not visible above ground so people imagined it bottomless.

The entire valley was a lake in prehistoric times and underground streams and springs still exist. Ever see steam coming out of storm drains on E Street? That is from hot springs below the city. There are also tunnels once used by Chinese immigrants. Dad visited them often as a child.

Lost Lake was fun in the 50s and 60s. I grew up in the area and swam, hiked, camped, explored and panned for gold all over the area. By the 90s, it became the scene of gang activity, rapes, drugs and murders. I recommend caution if you visit the area.

Re: Lost Lake of the Cajon Pass

My mom used to go there as a kid, and so have I... It has definitely changed over the years and it really saddens me!! Where are the tunnels at that you mentioned and morman trails?? Never heard of them!!

Thanks-
Robyn.

Lost Lake in Cajon Pass

The tunnels' entrances have been closed for a long time and the artifacts raided by one of the town's mayors. One entrance was at the bank on E Street. Another was in the old Chinatown area. As for the Mormons, the Mormons traveled over the mountains in covered wagons ...there were no trails for the most part, they simply made their own. If you speak to my friend Ger Brassfield at the Historical Society, he can tell you exactly where the trails were located. The Historical Society is, I believe, at the main library. Mormon Rocks are the wonderfully large rounded boulders seen in Cajon Pass, where the Mormon Trail and railroad meet. Great climbing.

Re: Lost Lake in Cajon Pass

I'm sorry, but the location of the trails are better known (and told) by Nick Cataldo, also of the Historical Society, which, incidentally, is located at the corner of 8th and D street. Nick has a once-a-year historical tour from the top of the Cajon Pass, down past the John Brown toll road, Mormon rocks, certain old route 66 stops, Blue Cut, and other interesting bits of informative stops. Look for the tour to be advertised around November in the Sun newspaper. Who is this "anonymous person who knows me.....

Lost Lake in the Cajon Pass

How do i get to the Lost Lake, and is there a fee?

Re: Lost Lake in the Cajon Pass

Its free

Re: Lost Lake in the Cajon Pass

215north get off kenwood.make a left.go up cajon pass until you get to your first left turn, continue going straight passing two train tracks, you will eventually see an opening in the road allowing you to turn right you will see a restroom and something that looks like its blocking you from entering but don't mind that just park walk up the little hill then there you are. Yes you need a mountain pass to park up there that u can buy at a gas station up there

Re: Lost Lake in the Cajon Pass

The Lat./Long. coordinates of Lost Lake are:
34.273, -117.4655
You can enter those coordinates at most map websites in their search box.

Lost Lake

The Lost Lake was beautiful! Almost impossible to find.

My very good friend took me there. He told me about how when he was younger he used to go four-wheeling at Lost Lake, and dive into the lake and go swimming. Two people told me that there was 2 or more "lost lakes". All I know is that when my friend took me to the lake, I had to look almost completely straight down. And I took pictures. It's beautiful.

I'm from Florida, and we have no mountains nor hills. So to see something like that was breath taking. We went close to the water. I would say that we climbed down but it was more like sliding down. I tried to climb back to the top by the golf course, but I kept sliding back down.

I thought that was a really nice surprise. Like a late birthday gift, or birthday surprise. :D

Drowned babies at Lost Lake in Cajon Pass

A co-worker told me that her two baby girls drowned in this lake in 1974. Has anyone heard of this?
I'm trying to help her heal from it and any information would be greatly appreciated.
Obviously the pain still exhists in her life, such a tragedy.

Re: Drowned babies at Lost Lake in Cajon Pass

I am her sister inlaw it did happen and was so tragic for all of us. Thanks for a friend and helping her with this. God bless you and of course her.

Re: Drowned babies at Lost Lake in Cajon Pass

Yes! I believe her and her huband were our neighbors! I believe I was 7-8 and everyone was so dad. My parents were chuck & Mary bowers.

Re: The Mystery of Lost Lake of the Cajon Pass

My dad took me & my 2 brothers to Lost Lake all the time and go fishing, shoot crawdads with bebe guns and smoke some bomb ass weed eventually when i became a pot head at 18. i just have so many memories there and enjoy every moment there thinking about the good times. my parents told me there is a school bus way way way down there at the bottom of the lake thats been there for years! i'd go swimming there too. can't wait to go fishing again.
