MILLINOCKET — About 200 geologists are in northern Maine for a field conference.

The 105th New England Intercollegiate Geological Conference is aimed at exposing geology students to field investigations. A total of 17 trips were being run from Friday to Sunday, covering everything from the glacial history of Mount Katahdin to the origin of ore at Katahdin Iron Works.

This is the 20th time the event has been held in Maine. The Maine Department of Agriculture, Conservation and Forestry’s Maine Geological Survey staff is conducting five of the trips.
