When you dig deep down under the ground, there’s a huge chance that you will encounter “natural form of gas” which are produced by the “fossil fuels”. These fossil fuels are actually the decayed remains of plants and animals processed for over a thousand years. And according to science, these gas are mainly made out of hydrocarbon composition primarily “methane gas”.

Some of you my fellow treasure hunters does often encounter methane gas especially when you have dug a very deep depth of hole. It is actually natural to encounter this form of gas but it is also possible that it was setup by the Japanese Imperial Army as a form of trap.

Gold miners also often encounter this form of gas but through their experiences, they already know how to deal with it.

Is methane gas dangerous and toxic?

Methane gas is highly dangerous especially at an area where there’s a very high level of concentration. Anyone can easily tell a highly concentrated level of methane gas from the strong unpleasant odor of the gas similar to the smell of a “rotten egg”. The danger is that, the methane gas may get ignited out from the small sparks generated by the impact of your manual tools particularly when hitting a very hard rock. If this happens, the methane gas may cause powerful explosion.

When it comes to toxicity, methane gas is actually non-toxic however, it is an “asphyxiant” which means that it can displace the oxygen within your body making you unable to breath. Many treasure hunters have already fallen victim on this kind of condition which took their lives.

Is There a Tool that can Detect the Presence of Methane Gas?

Your metal detector won’t be able to detect methane gas but a dowsing tool might. Honestly, it is hard to detect this form of gas unless you reached the portion underground where there’s a presence of high level methane gas. But if that happens, you may not be able to escape where you may end up dying from asphyxiation.

The best method to detect presence of methane gas is through observation of these following symptoms:

1. Headaches
2. Dizziness
3. Fatigue
4. Confusion
5. Stomach Pains
6. Difficulty of Breathing

If it happens that your diggers experiences those symptoms, it means that they are getting closer to a portion where there’s a high level of methane gas concentration. Thus, you should stop and make the necessary preparations before you intend to proceed.

Confirming the Odor if its Toxic or Not

I’ve been receiving several comments about various forms of odors they encountered under the ground. Some says that the odor smells like a dead rat or rotten egg. While others experiences smelling something sweet like perfumes. Regardless of the type of odor (good or bad), it is common sense not to inhale it.

What you need to do is to confirm that odor if it is dangerously toxic or not. So how to do it?

The Traditional Method of Animal Sacrifice

This traditional method does not require a spiritual medium to perform some kind of ritual. Probably, your prayer is already good enough by simply praying that the creature will survive the test procedure. It’s because, you will be exposing the creature into the hole with the strange odor.

We often use chicken as a test subject. If it happens that the chicken survived for three days then it means that the odor is harmless. You can also use a rat (must be kept inside a cage so that it won’t escape), frog and some other kind of pests.

Getting Rid of the Dangerous Gas

If you confirmed that the odor is a form of dangerous gas (assuming its methane), now what are you going to do? Of course, you need to get rid of the gas in order for you to proceed on your excavation.

The method that we use to get rid of the gas is to use a “blower machine”. Continuously pump air into the hole which will replace the gas into fresh breathable air keeping the concentration at a safe level. And to make it a bit more secure for the diggers, its best that they should still wear their own gas mask. Wearing gas mask still offers the best protection against inhaling the dangerous gas.

Some says that the use of blower machine does not work for them because as they proceed on digging the hardened soil, the gas leaks tends to become stronger. If this is the case then stop digging with your shovel. I suggest using ex plo sives. Although, this requires some experience because wrong usage can collapse your entire hole. Apply at least a minimal force to shock the wall or layer which will release most of the gas. Then, continue pumping air again. Repeat the process for the second time if gas leak still persists.

Controversy About the Use of Poison Gas

There is actually a very controversial argument about the use of poison gas in Asia as a form of chemical weapon in the past World War 2. The Japanese Imperial Army were accused of using poison gas which they used as deadly traps in protecting their hidden treasures. However, there is some source who claims that the US intelligence has confirmed that no “nerve gases” were used in Asia during the second world war. Despite, there is actually another conflicting source of information claiming that the Japanese Imperial Army developed and conducted several experimental tests related to chemical and poison gases.

Warning Poison Gas

In my own personal opinion, the Japanese Imperial Army probably conducted experimental tests with chemicals and poison gases as weapons but never produced any good results. This is probably the reason why they weren’t able to use it during the war until the Americans discovered the nukes.

Their experiments with the chemicals was also probably the reason why they were able to produce extremely hard form of concretes which they used to encased their treasures. There was also the rumored chemical which they used to melt rocks to hide treasure deposits inside them so as to carve signs or symbols on their surfaces.

Moreover, natural gas or poison gas traps are serious risks for treasure hunters. So my best advice is that, “if you do not know how to handle the trap then it’s better to stop your operation” or you’ll risk the lives of your diggers (so as yourself if you are also digging).

33 Comments to “Natural Gas Underground As Traps”

    • Sir Elmo. We reached 12 feet in our diggings where we smelled some kind of odor similar to methane gas. So we decided to stop our operation. After two months, we decided to resume our excavation but the odor was still there. How come that we only dug 12 feet then we already encountered this strange gas? Is this a sign that the item is near?


      We are not sure if that is a methane gas but my speculation is that, it could be an odor emitted by decayed bodies of either humans or animals in the past. In short, the area you are digging could be a burial site. Anyway, use blower and gas masks for your diggers to continue with your excavation.

    • Sir Elmo Good day! We are digging our hole for almost 50 meters now then suddenly, we encountered a gas. We do not know if it is a natural gas or cyanide. Anyway, we currently stopped our operation due to the lack of financial support. And because of the gas, we also need air blower.

      Prior to this operation, the signs that we encountered were two vertical lines that were engraved on the side of a very large rock. On top of this rock, there was a big clam shell. As we started digging, we discovered a human skeleton.

      Sir Elmo, can I ask if we are digging on the correct spot? Is the gas telling us that we are near the deposit?

      Hoping to hear from you soon Sir Elmo. Thanks a lot.


      In my own opinion, I think that your site is positive. The gas is probably a poison trap. If you do not have access to an air blower then leave the hole open for several days. However, if it does not go away then you have to find a way to acquire such equipment including gas masks.

    • Hi Sir, we are already more or less than 130 feet deep in our digging. We passed a manhole of 10 feet made of very hard concrete. Then as our diggers continued for another 3 feet, they encountered a poisonous gas and substance which is color red. He almost died but thanks to the Emperador who saves his life.

      What we encountered next is a flat concrete cement that is very hard and seems like a flooring. We are able to get rid half of its portion and found a lot of shells underneath. What does it mean? Are we on the right track? How many more feet do we need to go? Thank you and good day.


      You have to be careful being exposed on that contaminated substance. The effect may not be quick but symptoms will suddenly appear after a few months. It is highly advisable to use water and flash the contaminated substance before you continue working on it. Anyway, I think that you are on the right track. Simply continue digging it.

    • You can know that you are on the right track and you are near if you will encounter markers.. and in your digging spot it will be reversible as if you encounter big markers you will encounter small markers as you go deeper in your digging…

    • Sir Elmo thank you for your reply. Almost everyday I open your blog checking your reply on my query. Sir Elmo we already have air blower, we are using gas mask that is used by spray painting. We continue to dig in a while but we stop because our diggers worries of our hole have a possibilities to collapse. Our hole is only 3 meters in diameter. When they are at the bottom of 50 meters, taking some piled rocks of same size, like a size of a coconut. The gravel portion at 30 meters is falling down. So, we decided to stop.

      We are figuring now to put some bracket of wood and plain sheet around the side of our hole.

      Sir Elmo, that pile of rocks at the bottom of same same size, what is it? what are those rocks mean for treasure hunter? they told me when they remove one of those rocks they saw a smoke and smell of a gas. but thanks to our air blower, its just go up in an instant.

      Sir Elmo Thanks again, we hope that you will guide us all the way. God Bless!

    • If those rocks are quite heavy for their sizes them you should break them apart. Otherwise, it is a sign.

    • If it is really a methane gas then in most cases the item is very near because gold bars can produce methane gas lalo na if the item was covered by a hard cement…

    • Sir good noon, as we dig on the ground there is star in a rectangular shape. On the other side, there is well like that form like a sun but only has 4 raise.

    • The star sign represent the deposit which mean that it was hidden by a high ranking military officer which also mean, it is a large deposit. The 4 spikes of the sun mean, 4 steps which I think is towards the engraved star.

    • What a nice forum very cooperative and really we will know a lot as far as treasure hunters is concern. God bless Sir.

    • Thanks. Feel free to participate, ask questions and interact with other fellow treasure hunters.

    • Good day sir! The cousin of my uncle has this land that is so strange. She told us that when they were young they used to play on a big rock near a very old tree. Then sometime last year a Japanese tourist came to her and asked permission if he could dig around the site. My aunt refused and instead went to my father and asked if they could dig it.

      So my father and his companions started digging on the spot near the big rock. They only dug about 4 feet when they smashed into a cement, which was about 10 feet wide or more. But they are having a hard time because there is water on the digging site.

      Sir can I ask if this is a positive sign that there is a treasure hidden on the site? Another thing is, the friend of my husband is working on a treasure hunter and he accidentally told my husband that his boss recently found treasures enclosed on big slightly rocks. The sign such as the old tree, a big slightly brown rock and a cement was also present. Could it be possible that the treasure was enclosed on the rock?

      Thank you Sir.

    • That is so interesting. Those Japanese tourists probably have a treasure map on their hand and their presence on your land confirm that there is a hidden deposit.

      Moreover, it is possible that the treasure can be hidden inside a certain rock but we actually need signs to confirm that. Thus, my suggestion is to explore the site and try to look for markers.

    • Hi Elmo,

      we dug about 14 yards deep, person underground suddenly experience cough with shortness of breath. Could it mean that the target is almost there? What is the best remedy if someone inhaled this poisonous gas?

    • Yes, the item should be just around the corner. If you can find signs around the better because it can help pinpoint the exact location of the item.

      If someone inhaled a poisonous gas, and his condition is worse then he needs to be immediately brought to the hospital where he will be treated with oxygen therapy.

    • Hi Elmo, there could be a poison, the digger cannot continuously work because he experienced something like, a foul odor, then one time smell like downy. His throat feels irritating then continuous cough. How can we eliminate the poison, although water overflows overnight, but still experienced unusual even water subsides.

    • Hello Sir, is it true that there is a poison gas neutralizer? How true that it can only purchase to JICA agency as per my source it so very expensive?


  • Hi Sir Elmo,

    I just want to ask something if our hands hold the stone we got from our digging site and it becomes itchy, is it possible that there is poison in there? and what is the best solution to get rid of that poison?

    • If you have been over exposed with the contamination then that’s dangerous but if not, then you will be okay. Just wash your hands with soap and you will be okay.

  • Hi Sir Elmo,

    How are you and thank you so much for all the sacrifices you did just to share your past experiences and knowledge to all the TH out there. Your kindness mean so much and to me, you’re like the guiding angel to all TH out there.

    In our 4th hole, we are convince that what people are saying is true. The deeper we go, the more signs we encounter. We can’t make wider holes so not to damage existing busy walkways, near house columns and walls. We can only make hole with a diameter of 4-5 feet.

    Compare to what I’ve been reading in respect to other TH comment, I guess we’re a bit lucky because our site is not so much contaminated. Though, the soil smells like rotten steel or iron. We made a test on the black soil (black soil suppose to be very fertile) we plant vegetable but it doesn’t grow and the look is stagnant compare to other vegetable we plant on a normal brown soil – that we already made 3-5 times cropping. Like what you’ve mention to your post, watery site have more chances that the poison in the soil has been wash out or has been flushed out. However, we decided to stop our digging after reviewing all the “strange” rocks, stones and other signs that we uncovered. We’re afraid we might hit a poisoned gas. Based on signs and codes that we saw, a chicken head like stone signifies poison? In this regard, we would like to consult you first and please advice. I have already post all the pictures in your FB account.

    Hope to hear from you soon. We plan to continue our digging after we received some feedback from you. And hopefully, we can have your advice before summer ends or else we wait until next year summer. Once a typhoon hit our place, the water level is just around 2 feet below from surface.

    Again, thank you and look forward.

    • Thanks for appreciating and reading my blog. There are actually more important topics that I would like to share about treasure hunting but I really do not have much time to write about them.

      Anyway, about your concern, I am having a hard time trying to search for the photos that you sent to my FB page because messages from my FB page gets accumulated very fast. Thus, I will give my insight based on what you described here in your comment.

      The testing process that you made with the black soil confirms that it is contaminated which is dangerous but it is a good sign indicating the presence of a treasure deposit.

      Yes, the best method to remove the chemicals contaminating the soil is by flashing it with water. If there is a running water nearby such as a creek, you can divert some water into the area watering it for several days to flush the chemicals.

      When it come to poison gas, you need to immediately stop digging the moment you smell something that is either terrible or sweet. You can confirm that it is a trap if the smell becomes more stronger as you continue digging.

      The chicken head is a bad and good sign. Follow the direction of its beak but you need to proceed with caution because of the dangerous traps.

  • Hi, I am a big fan and follower. Do you have an e-mail where I can send some pictures that needs your expertise?
