I have been asked about volcanoes as we are currently in the Bering Sea very close to the Aleutian Islands which are made up of a long chain of volcanoes, so I thought I might write a few words. I have been interested in volcanoes for almost 30 years and I have been lucky enough to travel around the world to see and climb many of them. Most of my research has been looking at the material that Australian volcanoes produced 300 to 400 million years ago. These volcanoes are long gone but we can still read the story of their eruption in the deposits they leave behind.
