Yvonne has the great fortune to live beside Lake Te Anau, the gateway to Fiordland National Park, where she propagates native plants for a small revegetation project. She has worked in Fiordland as geologist and kayak guide, and has also worked in the polar regions for many years. Yvonne first visited Antarctica in 1990, and subsequently explored the sub-Antarctic islands and Arctic regions. Yvonne has a Ph.D. in Antarctic geology and has been involved with projects examining changing climate and habitat diversity. For many years she ran a multidisciplinary post-graduate Antarctic studies course at the University of Canterbury and is editor and author of the accompanying text Exploring Antarctica: An Introduction to the Last Continent. More recently she has been working with some of the oldest rocks in Tanzania. As an avid outdoor enthusiast, Yvonne has led many international kayaking and climbing trips, and authored a mountaineering guide to one of New Zealand’s most remote mountain regions.
