During the summer and autumn we offer guided geology tours in both Valdres and the Jotunheimen National Park. During the tour you will learn about the events that have occurred over the last 500 million years, that have shaped the landscape to how we know it today. Why is Bitihorn such a prominent shape? Why does the Besseggen ridge even exist? And why is Jotunheimen home to the biggest mountains in Norway? You'll find out the answer to all of these questions (and many more!) on a guided hiking tour.About your Guide: Dr. Alexandra Henderson is both a professional geologist and outdoor guide. She holds a PhD in Geology, where she wrote her thesis on the early development of the Himalaya, and has experience working as a geologist in Scotland, England, India, and Norway.
