YELLOWSTONE volcano is the subject of much speculation over whether there will be a major eruption in the future – but now National Park’s authorities have a more pressing issue to worry about as experts warned of toxic gases venting from the supervolcano.

Yellowstone National Park is home to thousands of hot springs and geysers spewing clouds of mostly harmless, rotten-smelling gases. But in the deeper parts of the Yellowstone wilderness where tourists are told not to stray, toxic fumes of lethal gas are powerful enough to kill.

USGS scientists studying the Yellowstone volcano have warned of the ever-present danger in the latest issue of the weekly Yellowstone Caldera Chronicles.

Dozens of Yellowstone animals have dropped dead over the years as a result of inhaling toxic fumes. The two killers are poisonous levels of carbon dioxide (CO2) and hydrogen sulphide (H2S), which are concentrating around ground levels.

Most of the gases emitted by Yellowstone’s network of hydrothermal pipes are harmless water vapour gases. But hiding in these emissions could be concentrations of toxic gases, which have proven to be lethal to animals.

CO2 is particularly dangerous because it is an odourless and colourless gas. H2S on the other hand is easier to spot thanks it to its distinctive smell of rotting-eggs but the gas is also colourless and flammable. Both gases typical pool around ground levels because they are heavier than air. This can be absolutely lethal to animal grazing in the parks fields with their noses close to the ground.

In most circumstances, wind will dilute carbon dioxide and hydrogen sulphide to low concentrations that do not threaten the health of people and animals. However, in certain very stable atmospheric conditions, though, these relatively heavy gases can accumulate in low-lying areas and pose a serious hazard.

In 1897, geologist Thomas Jaggar (who would later go on to found the Hawaii Volcano Observatory) led a field party to visit “Death Gulch”, a small, steep ravine in a remote hot springs area in what is now Yellowstone National Park. Here, the deaths of numerous bears, elk, rodents and insects had been reported. The group came across eight new bear carcasses during their visit to Death Gulch, and Jaggar surmised that their deaths had been caused by exposure to poisonous levels of carbon dioxide (CO2) and hydrogen sulfide (H2S) gases.

Over a hundred years later, in 2004, five dead bison were discovered in Yellowstone’s Norris Geyser Basin. Strangely, the bison lacked markings on their bodies that would suggest they were attacked by predators. Based on the position of their bodies, it appeared that the animals had died suddenly and as a group. Similar to the events at Death Gulch, park scientists concluded that their deaths were likely caused by buildup of lethal levels of carbon dioxide and hydrogen sulfide gases at the ground level, where the animals were grazing.

Under most weather conditions, visitors will not be bothered by the gas emissions that are an integral part of Yellowstone’s fascinating hydrothermal areas. However, as recommended by the National Park Service, people should remain aware of potential gas hazards when exploring these areas and leave immediately if feeling sick. Even though there is no record of any human deaths due to exposure to gases at Yellowstone, the lessons of Death Gulch and the Norris bison provide warnings that should be heeded.

    Do you know how many Reptilian (or hybrid) agents are working in order to influence the opinion in general? Reptilian agencies are really busy try to influence people’s opinions. How they are doing is they hire thousands of agents for cheap money and incentives, and give them 100 ihpones so that those agents can comment some influential websites or Youtube channels. Those agents put those 100 ihpones on a special rack (e.g. Black Floor Standing Wire Rack) so that they can see those 100 phones at once. Then they comment super short sentences even they don’t make sense at all. The objective of this operation is wash away the important and intelligent comments that might influence people’s opinion out of the main page. If they can inundate those influential comments with thousands of stupid and even doesn’t make sense comments, almost nobody can find those influential comments.

    Reptilian entities can influence people’s opinion For example, “Alex Jones are right wing nuts. Everything he said is completely wrong and a lie.” if they can input those comments thousands of times, they win!

    Of course, Reptilian entities can input those comments by robots. I saw the same repeating comments time after time inputted by the same name guys. Those repeating comments might be inserted by robots.

  2. RT does not ban Alex Jones.

    Alex Jones: “World elite in the Bohemian Club”

    I have never seen a right wing nuts talking about Bohemian Club? Right wing nuts have usually tight mouths with NAZI uniform. They do not talk about “911 is the insider job! The government did that!” How those reptilian entities categorize “Alex Jones is right wing nuts” is just crazy. Banning some influential guy out of social media is not a good tactics for Reptilian entities. Let any body talk! Where is the freedom of speech on this country?

    The last scene with floating city on a cloud is not created by blue beam. Reptilian entities do not have the even power to show you blue beam image. This city over the cloud had been created by Galactic Federation of Light to show people that there are some other dimensions exist. NASA and top military reptilians know some other dimensions exist. But just they do not tell you the truth.

  4. 6.8 Magnitude Earthquake Simulated by Underground Nuclear Explosion!

    Before 2011, all the huge earthquakes might NOT natural earthquakes. Phil Schneider who was a geologist for secret underground base construction, and also the only one who shot and killed 2 Large Grey Aliens said “Kobe Earthquake was an artificial earthquake created by underground nuclear detonation.” He had been assassinated by the Reptilian entity in order to shut his mouth. But one day, his wife got a mysterious visitor from Japan. He told her “When we win, we are able to pay some money for you.” Why US military made Kobe artificial earthquake? I saw some information that at that time, Japan had created a super computer “Kyo”. But US side of Reptilian entities did not like Japan became a leader of super computer industry. That was why US military created a huge earthquake and destroy the super computer “Kyo” located in Kobe. Phil Schneider had that insider information, and started speak about it. One of the reasons he was assassinated was he started talking about artificial earthquakes US military had been created in many countries instead declear war against those countries.

    • How did they make the detonation under ground in Japan? I’ve found there was a bridge construction in Kobe. The contractor of the bridge construction was “Halliburton”. The epicenter of Kobe earthquake was near the bridge construction area. How deep they can dig in order to build a huge bridge foundation? Or detonate a nuke?
