With a tip of the hat to Norman Geras, here are some amazing photographs of an expedition to the lava lake in Africa’s Nyiragongo Crater.

    Wow. Wowie kazowie. Thanks.

    Question[s] though. Photo #10 (I think) – what’s the measurement on the graph paper illustrating the height of the “walls”? My eyesight is kinda limiting. From the guy standing at the base – for whom I estimated at ‘about’ six feet – would the walls be ‘about’ 50 feet high?

    It appears Malcolm, you’ve given me something to do this weekend. You wouldn’t, by any chance, have the proper link handy for determining the composition and viscosity of the magma would you?

    Well, I can’t help you much at the moment, JK; I’m at the office, so don’t have all my usual magma-viscosity links handy.

    But I do know that according to the little ruler tool on Google Earth, the lava lake is about 0.13 miles wide.
