This volcano is situated in the very east of Java. The crater is filled by a greenish sulphuric acid lake. A huge sulphur body has formed near the shore, brown hot sulphuric steam rises hissing. When the wind carries the cloud towards you, breathing is almost impossible, the acid bites your eyes and nose. Some of the vapour is carried away in pipes, at the ends of which the yellow element condenses and slowly forms congealing puddles. In large blocks, it is filled into carrying baskets and these are dragged up the crater and down the other side by the workers for about 3 euros a day. (See also my books The Formation of Mountains and The World of Mineral Deposits.)
In the meantime, we have crossed Bali and taken the ferry to Lombok (20 km in 6 hours). The next destination is the small offshore Gili Islands.
