In 2008 I was the recipient of the Roderick Dew Travel Grant and went to Iceland to see the effects of the 1973 eruption of the volcano Skaftafell on Heimaey in the Vestmann Island group. There were numerous signs of the islander's struggle to keep their only port from being closed off by the lava and ash. Also seen were the effect of Jokulhaups; massive floods caused by ice dams breaking, often without warming, and releasing millions of cubic feet of glacial melt water. These floods destroy everything in their path and often deposit huge boulders called glacial erratics miles from their point of origin.
