Sulfur So I got to Pos Paltuding, the "outpost" at the base of the Ijen volcano. Shared a bed in a crumbling, freezing cold shack with an Italian explorer who had madness in his eyes and kept mumbling about "The Blue Flame". At 2:45AM, Ulrich, I and the crazed Italian started the trek up the volcano. This is a photo of one of the locals who carry up to 200LBS (80 KG) of raw Sulfur out of the volcano and down the mountain by the light of flaming torches.
