Giant Crystals In Deadly Warm Cave - Angry Planet 311 - Crystal Cave

But it is a intensely difficult spot to explore – with temperatures over 50 degrees C and humidity approaching 100%. George leads an Explorers Club Flag Expedition into the cave, wearing special refrigerated suits and respirators to battle the extreme environment.
