This is a picture of the pupils as they descended into the crater of Eldfell volcano (which last erupted in 1973 ). Just before this photograph was taken the group had enjoyed spectacular views over the Westmann Islands as well as to the icecaps and mountains (and Hekla volcano) on the mainland (all the time whilst warming their bottoms on the summit steam vents on the crater rim).
So far we've done boiling mud puddles, lava fields, geysirs, glaciers, waterfalls and volcanoes (but, as Ian keeps telling us , we ain't seen nothing yet!).
