By Mark Jenkins Photographs by Carsten Peter The Swiss have mountains, so they climb. Canadi- ans have lakes, so they canoe. e Australians have canyons, so they go canyoneering, a hybrid form of madness halfway between mountaineering and caving in which you go down instead of up, o en through wet tunnels and narrow passageways. Unlike other places with slot canyons, such as Utah, Jordan, or Corsica, Australia has a rich, deep heritage of canyoneering. In a way, it's an extreme form of bushwalking, something Ab- origines were doing tens of thousands of years before Mark Jenkins last wrote about big-wall climbing in Yosemite Valley in May 2011. Carsten Peter photographed an expedition into the crater of Nyiragongo, a volcano in the Democratic Republic of the Congo, for our April 2011 issue.
