In 2013, the crater's flame intensity and temperatures were at its recorded peak. At the same time, renowned Canadian explorer, George Kourounis, became the first – and only – person to enter the crater wearing a full heat-reflective Kevlar/Nomex suit and a firefighter's Self-Contained Breathing Apparatus (SCBA) to provide oxygen. He descended to the 752 °F (400 °C) crater floor and retrieved soil samples. Scientists later found extremophile bacteria living in the scorched earth samples Kourounis provided.
Wtf that's the craziest part of this story!
