High Res Ijen Crater Map and Surrounding

The volcanic cone of Ijen dominates the landscape at the eastern end of Java. Crater of Ijen is filled by a spectacular turquoise blue lake, its surface streaked in wind-blown patterns of yellow sulphur. Kawah Ijen is the world's largest highly acidic lake and is the site of a labor-intensive sulfur mining operation in which sulfur-laden baskets are hand-carried from the crater floor. .
