Satrio ing Pringgodeni
^^I heard abt Ijen volcano and local sulfur miners from a documentary film directed by Michael Glawogger.Ijen Crater
Ijen Crater is the biggest crater lake in Java. The sulfur crater lake lies between a natural dams of deeply etched rock. It is 200 meters deep and contains about 36million cubic meters of steaming acid water, shrouded in a smelling swirling sulfur cloud. Inside the crater the different color and size of stones are found. Indeed the crater of Ijen is beautiful garden of stone as well.
