Entering the 'Door to Hell' (2024)

Explorerand adventurer George Kourounis has had many memorable experiences in nature’s extremeenvironments—chasingtornadoes across the U.S.Midwest, swimming withpiranhas in Venezuela, even getting married on acraterof aneruptingvolcanoin the South Pacific. But a recent trektoremoteTurkmenistan may be one of his most excitingexpeditions.

It was probably the only expedition where he admitted to feeling “a bit like a baked potato.”

Kourounis was the first individual todescendinto a 30-meter (100-foot) deep pit of fire known as the “Door to Hell.” The Door to Hell is a crater in a largenatural gasfield that has been burning for decades. It is said that aSoviet oil rigfell into the crater in 1971, and ageologistdecided to get rid of the rig by setting the pit on fire. The resulting gas-fed flames continue burning to this day.

Kourounis and his team were unable toverifythe story behind the pit, but they definitely confirmed that the singular site exists.

The Canadian adventurer and former host of TV’sAngry Planethad wanted to visit the Door to Hell for years.

“Every now and then, I would look at pictures on the internet of the place again, and it just never exited my mind,” Kourounis says. “It was there like a splinter in my brain that I couldn’t get rid of.”

Burning Challenges and Bureaucracy

One might think thatrappelling into a burning pit would be the main challenge of this expedition, but Kourounis notes that his crew met anotherformidable obstacleearlier on.

“The biggest goal was just getting permission to get into the country,” he says. “That was our biggest concern because Turkmenistan is one of the most closed countries in the world.”

The crew finally gained entry into Turkmenistan in 2013 after two years of trying to get into the country. Kourounis says the crater, which is about 76 meters (250 feet) wide, looks like a volcano in the middle of thedesert.

“It is burning with atremendousamount of flame like there is a lot of fire down there,” he says. “Day or night, it is clearly burning. You can hear the roar of the fire if you stand at the edge. The heat, if you are downwind of it, is unbearable. There are thousands of little flames all around the edges and towards the center. Then there are two large flames in the middle at the bottom, and that is probably where the drilling rig hole was for the natural gasextraction.”

Before rappelling into the burning pit, Kourounis says he got hisequipment in order. This included a custom-made climbing harness made out ofKevlar, a self-contained breathing apparatus (similar toscubagear), fire-resistant ropes, and an otherworldly heat-resistant suit.

“They [the suits] look like aluminum foil and actually that makes sense because they are made from an aluminizedfabric,” Kourounis says. “These suits are used by some firefighters as well assteel-mill workers andvolcanologists, any occupation where you need to be close to intense heat. They reflect a lot of the radiant heat, but you still get pretty hot inside. I did feel a bit like a baked potato in there.”

Another very specialized piece of equipment that Kourounis brought to Turkmenistan was a heatprobedesigned by theengineers who build National Geographic’sCrittercams.

“It sort of looks like a sword,” Kourounis says. “It was able totransmit wirelessly back to the crater’s edge to a laptop. It could transmit theambient temperaturewhere I was as well as it had a long end on it that I could jam into the ground and get a reading of how hot the ground was.”

Entering the Door to Hell

Even after a few days of preparing, Kourounis says the idea of an actual descent into the Door to Hell wasnerve-wracking.

“I can tell you when you are standing on the edge of thisgiganticcrater filled with fire—it isintimidating,” he says.

Still, the adventurer did descend into the fiery hole.

“It wasn’t dark at all,” Kourounis says of the crater’s interior. “As a matter of fact, you are surrounded by flames, so everything has this orangehue.”

Once on the floor of the pit, Kourounis embarked on the scientific core of the expedition.

“The most important part of the mission and the whole thrust behind this entire expedition was to take some samples of thesoilat the bottom—sand, basically—and see if there is anyextremophile bacterialiving at the bottom that could give us clues to basically life in these extreme environments,” Kourounis says. “There areplanets that have been discovered outside of oursolar systemthat have a very hot,methane-rich environment kind of similar to what is in the crater. So, in essence, we were looking for alien life right here on Earth.”

“It’s a veryvolatileplace,” Kourounis says of the Door to Hell. “To give you an example of how volatile, at one point I kneeled down on the ground, and I’m digging in the sand to try and gather some samples from a little below the surface and as I’m digging with a small hand shovel, fire is coming out of the hole that I’m digging. I just opened up a newventas I’m digging down there!”

The soil samples were given to Dr. Stefan Green, the microbiologiston the expedition. Green says that a few kinds of bacteria were discovered in the soil from the crater floor. These extremophiles appear to be what Green calls “enriched” by the Door to Hell’s high temperature and lownutrientlevels, among other things.

Along with this discovery of unexpected life in one of Earth’s mostinhospitableplaces, the Door to Hell has an out-of-this-worldtingeto it, according to Kourounis.

“The orange glow from the flames makes the ground completely orange, and the walls of the crater look orange,” he says. “It really reminds me of being on a place like Mars, where you have that orange or red soil. It just has another-Earthly feel.”
