One most common question that I often come across is all about very hard concrete. If you are a reader of my blog then you should already know that concretes made by the Japanese Imperial Army (JIA) in WWII can’t be easily chiseled or break by any ordinary tools that we use today.

I myself have already encountered many of these hard objects and it can be pretty annoying dealing with them.

The reason why the JIA managed to construct such very hard material was due to their special chemicals that they often add into the mixture of their cement.

They often use it to encase their treasure which also serves as the items’ protection from damages.

Aside from encasing their treasure, they also use their special concrete in sealing entrances to their hidden tunnels especially the chamber where they stored large number of their precious loots.

Most treasure hunters do encounter a hard layer deep down the ground which is usually 80 feet deep or more. Unfortunately, this extremely hard layer of the ground is not made by the JIA but naturally-made. This layer is what they call as the “bedrock”.

What is bedrock?

Bedrock

As a treasure hunter definition, bedrock is the deepest layer of the ground possible for human to reach through common digging methods.

One characteristic of bedrock is that, as you attempt to break your way through the layer, it will simply get harder-and-harder until you definitely give up.

Another characteristic of bedrock is that, it does really look like concrete. This is the reason why majority of the amateurs often fall for this kind of mistake.

What to do when you encountered the bedrock?

When you finally encountered the bedrock, it only means one thing.

“It is time for you to stop.”

Why?

It’s because you have already reached the bottom end. If you insist of continuing then you will only damage your tools.

The next thing for you to do is to determine the main reason why you end up hitting the bedrock.

One possible reason is that, you have interpreted the signs incorrectly. I do understand that most amateurs who failed to decode the markings that they encountered simply tend to just continue digging straight towards their original direction.

This is why it is very important for treasure hunters to be able to interpret treasure signs and its meanings correctly.

If you have basic knowledge about interpreting the signs then that might not still be good enough. The JIA also do often use decoys for confusion which causes you to lose your track.

Another possible reason is that, you might have missed to notice a sign which indicate a “change in direction”. This is why it always very important to be very observant with all the objects you uncover especially rocks with markings on them.

What to do then?

If you are on this kind of situation where you went into the wrong direction, it does not mean that it is over. All you have to do is to retrace your digging back. Try going back to the layer or depth where you encountered the last treasure signs and then restart your assessment at that point.

Study the latest signs that you discovered and probably, there is one that tells you to shift your direction to a certain corner.

Do bedrock tunnel exist?

Bedrock Tunnel

Throughout my experience, I have not yet encountered bedrock tunneled by the JIA. But this does not mean that it does not exist. It is actually pretty much possible because of the special chemical that they secretly used.

You have to know that aside from the chemicals that they used as mixtures to their concrete, they also had powerful chemicals that can easily dissolve even the hardest type of rock. This explains why they can easily engraved artistic symbols or signs of buried treasures on rock’s hard surfaces.

Thus, they can use such chemical to create bedrock tunnels.

  • Sir,

    I am a beginner in TH. I study on it from your blog and on Facebook in the group of TH.

    My team spent almost 19th month breaking this hard layer which we encountered from three feet up to this moment wherein we managed to reach 16 ft.

    This hard material has different properties. It has epoxy type of material mixed with pink color clay and some were mixed with red or maroon just like what is used in clay pots.

    Is this material a bedrock or JIA concrete?

    • It is definitely not a bedrock due to those several elements that you mentioned. Bedrocks are just plain like concrete that is too tough to break.

  • Good Day sir ELMO!

    I would like to ask regarding our digging, we already reached 140 ft deep and we found a soil that is color RED and after that another color appears which is color BLACK. After encountering those kinds of soil, we already encountered a hard cement, we would like to know if that was already near to the chamber of the tunnel. Thank you!

    • Just like what I have covered on this post, you might have already encountered the bedrock which is extremely very hard object to penetrate especially when there is already a strong presence of water. Anyway, you may want to give a try breaking it for a few feet. If you are unable to do so then you are probably dealing with a bedrock.

  • We already dug about 25 ft and we encountered water that is green color and oily. What does this mean?

    Thanks.

    • Be careful because in most cases, water with strange colors are contaminated with dangerous chemicals especially when they emit a very strong odor.

  • Hi Sir Elmo,

    I just want to clarify about the color of soil and the last layer before reaching the items. We unearth color black soil mixed with crude oil when we wash it water. The water in the pail turn to black. There is a hole 1 inch in diameter. We follow a small hole and then next to black is orange but in the center of the hole is a divider that half is color black soil the other half is orange. And, the orange color soil smell like flower similar to perfume with sweet characteristic.

    After we unearth all orange soil and next is sand mixed with stone, in the center is red stone and after that we hit a yellow brown soil. I think it is a top soil and the hole we follow is gone.

    Sir Elmo are we near? The soil smell like perfume luckily we have gas mask. Some of our digger smell it outside. Are we near to object? Thanks a lot.

    • Those different layers of soil that you encountered are definite treasure signs. I actually covered this topic in my other post and I assume that you already read.

      The perfume that you smell can be dangerous if you inhale it to much into your system. You may seem to feel okay smelling it but in the long run, you will suddenly experience the bad symptoms.

      When you finally reached the final layer which is a yellow brown soil that came from the top, try checking the sides because there could be a change in direction.

      As for you question, I got a strong feeling that you might be near the hidden item.

  • Good day Sir,

    I discovered in our farm a big rectangular-shaped rock very similar to a life size tomb in Catholic cemeteries. Is this a positive sign for buried treasures? If yes then should I start digging from here or it’s just a reference point where the buried treasure is located. Thank you.

    • I would like you to inspect that rectangular rock for any obvious markings which can greatly help in providing clues about what you have to do next. If there is none, then you should give a try digging some shallow depths around while observing for any possible signs. If you found nothing then that rock is just a reference point.

  • Good day Sir Elmo, we found an arrow pointing to the north then we followed and we found the “y”. What is the exact location of the items? then we estimate the distance from arrow to the “y” sign it almost 30 meters.

    Thank you Sir and God bless.

    • A Y shaped symbol is often an interpretation pertaining to “intersection”. This could be an old creek or an old trail. The location of the item should be somewhere around the intersection point. In most cases, when you explore the intersection area, there should be some markings that will guide you on where to work or dig.

  • Sir, can you assist me in locating the treasure in my place? I accidentally found 4 sun engraved on a rock which is covered with water. The big rock is hidden under a stream. The 4 suns engraved on a sliding rock on a foot of a mountain where the stream is passing through.

    I have found 4 engraved sun on a creek on a Y intersection of creeks. Can you please advice me where to locate the treasure area Sir?

    • Those four suns indicates that there are four separate deposits. However, each of them have certain distance from one another which can be determined through the number of their spokes. Each spoke is often considered as 1 foot.

  • We happened to stumble on a rectangular rock which is human made, I guess! because it is almost perfectly cut. This happened when we visit our grandpa’s land which was known to be a Japanese headquarter during the war…and we also found a foot print on a rock. I will send you a video if you are interested since I need your guidance.

    • The rock is as thick as 8″ and its very hard.

      • If you have a metal detector, you can scan it. Otherwise, you may want to break it apart by any means necessary.

    • Everything that the is hand-made especially by the JIA can be considered as a marker that has something to do with treasures that they had hidden. Since your site used to be a Japanese Headquarters, there is indeed a huge chance that there is a large hidden deposit on that place. The only problem is that, you have to be careful when digging around because of the presence of dangerous traps – most likely vintage bombs.

      A foot print marker has something to do with direction. In general, it means that you need to follow the direction where the foot sign is facing at.

      No need to hassle yourself with the video, a well described description of the signs that you found is already good enough for me to give you my own interpretation.

  • Sir, I just want to ask. They are already in 35 meters deep, encountered very fishy smell, their skin is itchy and found a tire (car or truck), do they still continue or the item is already near their position. Thank you sir.

    • Base on your description, it seems that you diggers has finally encountered the contaminated layer which is causing those symptoms. As for you question, it depends on the volume of the hidden treasure. If it is a large hidden deposit then you will still have to encounter the vault which is a very thick type of concrete that is very hard to break. But if the deposit is small or medium, then you are probably near the item.

  • Sir I just want to ask on my land, there is 3 rock around 1 to 2 m distance each in triangular with marking on its rock 1 with rectangular shape 2 x 3 inches at the center of the rock. The second with U shape 4 x 5 inches at the bottom of the rock. The last one is like a point edge pointed away outside the 3 rocks which is in triangular form. Can you help me please. Thank you so much.

    • The first rock is telling you that the item is enclosed inside a certain container. As for the second rock, it’s engrave sign confirms that the item is hidden inside the container. The third rock has a directional marker which means that the item is hidden outside the area of those three rocks.
