Sailing in the narrow channel between Fergusson and Normanby Islands, in the D'Entrecasteaux archipelago of Papua New Guinea, we were surrounded by the cones of ancient volcanoes. Now they lie dormant and cloaked in jungle green, but they are certainly not extinct. At the base of Deidei volcano we explored a large area of hot-springs, with bubbling pools of mud and water. We followed our guides carefully. The rocky crust was thin and punctuated with holes. Beneath lay scalding water. Where the water flowed out and over the surface it deposited lines of travertine crystals, creating a series of shallow terraces. Steam and a faint whiff of sulphur filled the air, the atmosphere positively prehistoric.
