Kawah Ijen, East Java, Indonesia, is a part of a group of stratovolcanoes, connected to a rich vein of sulfur (a vein mined by painstaking hand) that expresses itself both in a startlingly blue lake and in these bright blue liquid sulfur flames.

Photographer Olivier Grunewald took these amazing photos in 2008. He lost two lenses and a camera in the process. He had to wear a gasmask and had to get rid of all the clothes we wore during the shoot.
