Traditional sulfur mining at Ijen Volcano, East Java, Indonesia. This image shows the dangerous and rugged conditions the miners face, including toxic smoke and high drops, as well as their lack of protective equipment. The pipes over which they are standing serve to guide sulfur vapors and condense them, thereby easing (well, relatively at least) production. What looks like clouds or steam is actually highly concentrated hydrogen sulphide and sulphur dioxide gases.\[1\]
