Marum volcano, Ambrym Island, Vanuatu, Sunday 19 September, 2010 - check out the photos of Drew Bristow and Johno Smith on Geoff Mackley's website(scroll to the bottom picture and you'll see Johno disappearing over the edge with the lava lake in the background).
Apparently, Geoff has managed to getsome fantastic footage but the climbing gear is taking a hammering from the sulfuric acid and ash!Drew Bristow 'pondering' at the lava lake edge! Photography by Bradley Ambrose.
