Kawah Ijen: The Blue Volcano

      In East Java, Indonesia, Kawah Ijen stands tall in the night sky. Within the volcano, there is a small sulfur mine where blue burning sulfur pours out. In the crater, there is a 200m deep lake of sulfuric acid where workers retrieve enormous chucks of pure sulfur.

     The environment around the molten crater is highly toxic. The photographer, Oliver Gruneweld, braved the treacherous environment and photographed the beautiful flames. At the beginning of the year, he also released a documentary in French about the volcano. 

Here is more pictures of the mountain:
