History of a mountain range: how do we unlock its secrets? — Johan Erikson

Part 7 of our Centennial Faculty Lecture Series
7 p.m., Viola George Auditorium - Alfond Hall
30 min., 30 min. Q&A

Taller but narrower than the Rocky Mountains, the Andes in northern South America have a story to tell about the different ways that mountain ranges grow. Come hear and see how river sands, radioactive elements, and the Earth's magnetic field can be used to decipher 15 million years of mountain growth and erosion.

Professor Erikson's geologic research in Maine has implications for interpretation of long-term climate changes and their effects on the landscape.
