Since my first polar expedition, to Ellesmere Island in 1992, I’ve been back to the Arctic or Antarctica almost every year, including three new routes to the South Pole, a double-season traverse of the Arctic Ocean and two crossings of Greenland. In 2012 I co-founded the International Polar Guides Association and am its current president. With over 25 expeditions to the North and South Poles, most as a guide for my company Icetrek, I’m fascinated by high latitude adventures.
