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?

I grew up going to this lake as a teenager in the early and mid 90's. My buddies and I built several quarter pipe style launch ramps to jump bicycles in with. It was awesome! So much so that now in my early thirties I tried it again with an even bigger ramp in summer 2011. Still got it Baby! I may have the cajones to do that but you would never find the sun settin' on my butt up there. Oh anyway, to attest to the actual depth, I CAN say that at only about 25 ft. from the south shore I let go of my bike and didnt have enough breath to find it when I dove to look for it. However, I did get real creeped out while down there too cuz it has an eerie quiet and a dark like no other body of water I've ever been in. I think for some of us its way cooler NOT to know everything about it.

Father and i went snorkeling there after loosing a couple lures. It most certainly has a bottom.

What was down there ?

Is there really a bottom ? Where in the lake were u ? The middle ? How deep is it

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.

did you Google it?
