Saturday, November 15, 2014, 1:00 PM - In July 2014 scientists were left scratching their heads after a massive hole appeared in northern Siberia. Now, four months later, researchers are venturing in to its depths for answers.
Initial reported suggest the crater was between 50 an 100 metres wide and opened up about two years ago.
Earlier this week, scientists climbed down the base of the crater in hopes of finding out how the hole formed.
According to the Siberian Times, scientists are working with the theory that gas caused underground explosions, prompting the crater.

The team used climbing equipment to journey to the base of the crater.
At the bottom sits a frozen lake that's at least 10.5 metres deep.
Researchers say they took measurements and collected data.
Next, they'll process the information in hopes of finding new clues.
