Kawah Ijen is Java's famous sulfur-belching volcanic crater. It is also the regular workplace for almost three hundred men, who make the grueling journey up the mountain and down the crater rim to mine sulfur.
The men depend on nothing more than a metal rod and sheer muscle power. They have no special equipment to assist them with the mining and little to no protection from the poisonous fumes that the volcano constantly expels. The job of the men at Kawah Ijen might be one of the most difficult and dangerous in the world.
