On The Volcanoes Of The World

Dallol, The Acid Volcano (1x8)

:

Arriving at the village, the group just washes up, as water is rare. Then he goes to Dallol, a very special site and one of the most difficult to access in the world: a salt dome raised by volcanic forces. With the help of Guy de Saint-Cyr, Fanny collects pink salt crystals. The volcanologist recommends caution to his companions, because the terrain is impregnated with acid.
