Indonesian Sulfur Miners Make Offering To Protect Against Disaster...BANYUWANGI, EAST JAVA - DECEMBER 17: Miners carry a goats head for burial in the crater as part of an annual offering ceremony on the Ijen volcano on December 17, 2013 in Yogyakarta, Indonesia. The ritual is performed by the sulfur miners of Mount Ijen who slaughter a goat and then bury the head in the crater of mount Ijenn. The sacrifice is performed to ward off potential disasters for the next year. The Ijen crater rises to 2,386m, with a depth of over 175m, making it one of the world's largest craters. Sulphur mining is a major industry in the region, made possible by an active vent at the edge of a lake, but the work is not without risks as the acidity of the water in the crater is high enough to dissolve clothing and cause breathing problems.
