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.

I fished in Lost Lake in the 1950's. We caught a type of fish that I was not familiar with. I know most of the usual fish in the area. Someone told us it might have been a "goggle eye" I have never found info or pictures of any fish called a name similar to "goggle eye. the largest fish we caught was about 16 to 18 inches long. Shape of a bass but had a smaller mouth and reminded us of a perch. I do not know if they still exist in the lake at this time. Any ideas.

I was there swimming not to long ago and saw a man catch a fish that looked like a bass but the eyes were huge and almost popping out! He was gonna take it home to find out what it was but released it fearing it might die and it turn out to be a pre historic fish. I just believe that its a bass that was way deep down under and its eyes popped out as it was surfaced. But what has my attention is the rumors of lost lake having no bottom! Any info?

THATZ TRUE LOST LAKE HAVE NO BOTTOM THEY CHECK ALREADY

I was told by the ranger who was opening the gate to lost lake yesterday that the Army Core of Engineers ran tests to determine the depth of the lake and he was told it was slighltly deeper than 300', but never saw any evidence of the tests performed and that they were never made available to the public or the National Forestry. He also said that he watched the engineers conduct the tests but doesn't think they were honest with him. He said they hit the 300' depth in certain spots but never did they hit bottom in the high end of the lake. He said the high end of the lake would be the east portion that faces the Interstate 15.. When looking at the lake the east portion appears very dark almost completely black, and yesterday being very warm about 83 degrees, the water was as cold as ice. I wouldn't say that I am a traveler, but I have been to about 40 different states in our great nation, and never in my life have I felt so uneasy, as I stood by the waters edge. Just a real creepy type of feeling. Like alot of horrible things have happened at this place. When leaving I spoke with the Ranger again who said the a volkswagon was pulled from the shallow end of the lake in around 2004 with four male passengers still in the vehicle, all of who had been shot in the head.. He also told me of Bikers who used lost lake as their party spot for many years and said he had heard stories of many people who were either raped and dumped in the lake by the bikers, or just killed and dumped in the lake.. He also said in the 1970s there were more than 20 people reported missing in that general area who were never seen or heard from again.. It is not a place I would want to hangout, especially after the sun goes down. Lost Lake is definiately a strange and mysterious place..

I was at the Lost Lake yesterday with my son who was visiting for the second time-first time with a school tour. The first thought that struck me was what a weird and unusual place for a lake to be. It seems to be in the middle of nowhere. It was dry land everywhere except for the lake location. It is a true oasis. Another thing I noticed is the clearness of the water. The water is as clear as can be. Around the edges, one can actually see the bottom of the water; that's how clear the water is. This will strike as odd judging by the length of time it has existed. It is in its natural state. No modernization or improvement has been attempted to make it a standard park. That is strange. It is eerie around the lake. The name "Lost Lake" befits this body of water. I wonder how it was discovered. It is actually in a place you don't expect water to exist. It seem to be flowing south while it's not. It is rather a small lake. It never dries up. You would expect a little body of water like that to dry up in the dry summer California heat. Not so. the level remains the same at any given time. The question is if there is a continuous flow of water from under the earth, why does it only replace or content with replenishing any taken amount and not overflow to form a stream, river or a bigger lake? It seems to have a natural overflow system or device in place. Another question is, if it is really flowing from the center of the earth, why is not hot or warm? Another strange observance is the absence of tell tale signs of approaching a body of water. It is dry land and brushes as usual and whooeh!! you are at the edge or about to run into it.
Is there water in the center of the earth? If so, why has the lake never frozen but always cold as was noted by someone? We were taught that the core of the earth is molten or liquid and immensely hot. Shouldn't hot lava be seeping out of the lake instead of cold water it were truly connected to earth's center? Is this lake a ticking time bomb and a ready avenue that may one day provide an easy outlet for a silent serious volcanic lava flow that may insidiously overtake a large area unnoticed. Has a diver ever been sent down there to explore the depth? There is something strange about that lake alright. Why has it not been developed into a park? Why is the public not warned of its depth? Does anyone has any true info. regarding this lake?

I go deep sea (ocean) fishing. When we eventually pull up a rock fish from about 300 feet, their eyes pop out and it is a sight to see. I don't know how deep you went when you pulled out "goggle eye" from Lost lake. If you went down more than 200 feet, then the popped eyes must be due to the pressure factor associated with fish that live deep down in water, otherwise it is just part of the lake's weirdness.

I THINK IT IS A PORTHOLE INTO AN OTHER DIMENSION.

How do we get some tv show crazy guy to dive it and record footage

Wow, a place that Huell Howser hasn't got to!

It's about the ONLY place Huell Howser hasn't been to yet!

The mystery of Lost Lake deepens! A man died in Lost Lake yesterday (September 4, 2011) while swimming. For unknown reasons he began to struggle, then drowned.

WE USED TO RACE OUR DIRT BIKES AROUND THE LAKE IN THE LATE 70'S AND EARLY 80'S . WE CAMPED THERE MANY NIGHTS AND HAD SOME OF THE BEST TIMES OF MY LIFE . IT WARMS UP IN THE SUMMER AND GETS COLD IN THE WINTER . NO MYSTERY HERE . SOMETIMES IT OVER FLOWS A LITTLE . SOMETIMES IT DON'T . IT'S FED BY UNDERGROUND . WE HAVE CAUGHT CRAWDADS TROUT AND CATFISH IN THE LAKE . WHEN BIKER GANGS USED THE LAKE IT WAS THE ONLY TIME YOU DIDN'T WANT TO BE THERE . WAS REALLY NICE WHEN YOU COULD CAMP AND RACE DIRT BIKES RIGHT ON THE LAKE , BUT THOSE DAYS ARE GONE AND IT'S NOT LIKE THE GOOD OLE DAYS . O YEA , THE CRAW DADS USED TO TASTE REALLY GOOD !!!!

why hasn't there been any research on this lake!!!!!!!!!!!!!!!!!

i went about 6 moths ago and caught a catfish with my uncle only to be fined for not having an adventure pass...we saw small shad swiming around and that catfish but that was it

 Why hasnt there been any research?????

Because it's just a friggin lake!  That's why..

 

My boyfriend scuba dived in Lost Lake around 1964 and it is at the deepest 25 feet. No it is not bottemless. It is impossible to be bottomless. Around 1962 it was very low and the same boyfriend rode across the bottom on his motorcycle.

Taking my son fishing there today...let's see what happens! Maybe we'll catch ourselves an unknown species of fish....or an alien!

I've been to this area many, many times over the last 25 years. Still a great place to quail hunt. The lake is not very friendly due to steep banks and heavy vegetation. It's not called lost lake for nothing, it's almost like a hole that opened up with high steep banks enclosing it hiding it from view.

On the north side atop the steep bank over looking the lake there is (or was 10 years ago) a touching memorial to a young womon who passed away too young. Her family made a small cross that is hidden by the brush unless you right on top of it. It had a picture and a short eulogy, her ashes were left at the lake. Perhaps a fire or weather has taken it but it’s still in my mind. RIP.

I want to know more about the history of lost lake prior to the 1900's and what other occurances has taken place since that time period.

Sorry, but according to the fish and game warden in the area the lake has never been drained.. It fills up as fast as water is scooped away for fires.. You must be mistaken that your boyfriend rode his motorcycle along the bottom of Lost Lake.. According to california records this was formed by an earthquake in the early 1800s. The seismic activity caused a crack very deep that filled this area with water. research it..

MY FATHER AND I LOST A NICE LURE SO WE GRABBED OUR SNORKEL GEAR AND WENT IN, FOUND LOTS OF LURES AND A UNOPENED COKE. THERE IS A BOTTOM I ASSURE YOU. NOTHING CRAZY ABOUT THE LAKE HOWEVER I WOULDN'T RECOMMEND CAMPING THERE. 3 PEOPLE GOT SHOT IN THERE SLEEPING BAGS WITH A SHOT GUN WHILE SLEEPING.

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.

Never said it was drained! I said it was low enough to ride the motorcycle across. It is a sag pond on the San Andreas fault. My boyfriend was a geology major and gives a lecture at the lake once a year as part of a Cal State San Bernardino class discussing the subduction zone where the Pacific Plate dives under the North American Plate. He has studied the lake and surrounding area since 1958. the earthquake you are most likely referring to was the 1857 quake that caused a rip in the topography of the surrounding area. The Fort Tejon earthquake of 1857 occurred at 8:20 AM PST Jan 9. Length of surface rupture was 225 miles with a maximum offset of 30 feet. They estimate it was about a 7.9 quake. Things change you know. I saw the water in the Santa Ana River splashing up over the bridge to Riverside by Fairmont Park in 1968 and now there is hardly any water above the surface. The Santa Ana River also wiped out the town of Agua Mansa when the water filled from bank to bank on Jan. 31st of 1862. Things change.

Those engineers were messing with you, perpetuating the myth. People want to believe the fairy tales. There definitely was a woman and her two children and her male friend that were murdered in Grand Terrace by her ex husband and dumped there at Lost Lake. That was in the San Bernardino Sun and I have the articles because we knew the young man.

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.

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

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

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.

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

Hickory Shad?
