Footage from daring volcanologists: Richard Roscoe (PhotoVolcanica) and Marc Szeglat.
The lava has an average maximum temperature of 500 degrees C. Not cold enough to touch, the mountain guide who fell in was severely burned and easily could have died. The carbon in the lava (also known as carbonitite lava) is not pure elemental carbon, it's in the structure of carbonate minerals like for example calcium carbonate, the dominant mineral in limestones. For a long time it was thought that the lava was partially just molten limestone but one more modern theory suggests that the carbonitite lava separates like oil from water in the magma chamber. The unique chemistry of this volcano has really interesting effects on the local ecology. Look up Lake Natron for a good creepy rabbit hole :)
