Dr. Stephen Norton earned rave reviews from the more than two dozen people on a Geology Walk he led recently at Sears Island.

Steve Norton received his A.B. in geology from Princeton University, and his M.A. and Ph.D. in geology from Harvard University. He retired from the University of Maine in 2008, having taught there and performed research for 40 years. Early in his career he conducted research with the U. S. Geological Survey and the Maine Geological Survey, unraveling the history of crustal rocks in western New England and Maine. His research continues to the present and is concerned with chemical processes at the Earth’s surface, specifically the interaction of water, rock materials and humans. His work has taken him to many places, including close to the North and South poles, Europe (with two years in Norway), and to Canada and Mexico. He came out of retirement this fall to teach his graduate course in geochemistry.

Last year, Steve co-taught a class on “Catastrophes” for the Penobscot ValleySenior College. Recently, he has given talks at the Downeast Salmon Federation, Orono Land Trust, The International Appalachian Trail Maine Chapter, College of the Atlantic, Acadia National Park and several Bucksport town committees,

The Geology Walk concluded a series of five natural resources theme walks sponsored by the Friends of Sears Island, a non-profit organization that provides stewardship for the land. For more information go to www.friendsofsearsisand.org.
