one as some of these earth's deepest places have stories as dark as their depths number 10 blue hole red sea also known as the diver cemetery the blue hole is located in dahab egypt with a depth of 328 feet while diving in the blue hole might not be dangerous itself this underwater sinkhole has a unique feature which makes it incredibly lethal at around 181 feet down there's a rock tunnel known as the arch that connects the hole with the red sea because the water is so clear light at the end of the tunnel makes the arch look a lot shorter than it really is when in reality the tunnel is 85 feet long this length together with a current that constantly flows into the blue hole from the red sea slows the progress down these factors make it so deadly for even the most experienced divers who attempt it thinking it will be easy unknown to them for its deceptive length and current the blue hole is associated with a death toll of between 130 to 200 a famous death here was 22 year old yuri lipskis who took a video camera with him descending uncontrollably to the bottom eerie as seen in the footage panics and tries to fill a buoyancy compensator but he's too deep and the pressure stops him from rising off the bottom his remains were collected the next day by deep water diving specialist tarik omar number nine door to hell gates of hell the door to hell in derweez turkmenistan is a soviet experiment that turned out to be bare unintended consequences in 1971 scientists initially wanted to use the remote desert site to drill for natural gas the ground beneath however collapsed as the drilling rig hit a natural cavern filled with gas and they had to stop the drilling the hole is approximately 230 feet wide and 65.5 feet deep fearing the spread of poisonous gases into the surrounding towns geologists intentionally lit the natural methane gas by tossing a grenade into the hole anticipating that it burned off within a week that was more than four decades ago and it has however been burning continuously ever since its glowing is visible from derweeze each night fittingly the name derweez means gate in the turkmen language so locals have dubbed the burning hole the gate to hell and is actively being encouraged as a tourist attraction site by the turkmen government at night camel spiders attracted to its light and warmth fall to their deaths in this pit's fiery bowels and if you think this place is not dangerous the number one will have you ossified number eight the cola super deep borehole the project to drill into the earth's surface began near mermax in prachensky district russia in the 1970s when soviet scientists wanted to learn more about the earth's crust over two decades they managed to dig more than 39 600 feet seven and a half miles into the earth so deep that if mount everest was placed into the hole its peak would still be underwater by more than 10 560 feet two miles the cola borehole is also further down than the wreck of the titanic which is 12 500 feet down into the ocean however in 1992 they had to stop drilling because the temperature was around 180 degrees celsius which was far much hotter than the scientists had projected it would be all this drilling wasn't for nothing though as some scientific discoveries were made the researchers found out that there is water at 12 kilometers into the earth's crust additionally they found 24 new types of long dead single-celled organisms and gained access to rocks that were 2.7 billion years old hidden underneath this rusty lid is the cola super deep borehole if you fell down the hole it would take around 4 minutes to reach the bottom locals in the area say that the hole is so deep you can hear the screams of people being tortured in hell hence its nickname the well to hell

per second and water only spills out into the glory hole when it reaches 15.5 feet above the level of the funnel and the last time this happened was in may 2006 for emily schwalleck the 72 feet wide
