Indonesian miners carry baskets of sulphur from the bottom of the crater of Indonesia's active Kajah Iwen volcano, in the extreme east of Java island. Some 350 sulphur miners eke out a dangerous and exhausting living on the active volcano, carrying hauls of up to 80 kilos of "yellow gold," which will be bought by local factories and used to refine sugar or make matches and medicines. The miners extract the liquid sulphur as it flows out of hot iron pipes. Once in the open air, it cools, crystallises and turns bright yellow. The sulphur is then loaded into wicker baskets at either end of bamboo yokes and carried back over the lip of the crater and down the side of the volcano, a treacherous journey of 2.5 miles.
