Geology of North Shore Eskers: In the Field

Course Overview

What is an esker, you inquire? You may not recognize them, but eskers are long deposits of sand and gravel criss-crossing the North, left from the last time a glacier rolled though the area. In this one day course, you’ll learn about the glacial geology of Minnesota, focusing specifically on the glacial features seen along the North Shore. You’ll learn to identify eskers from maps and aerial photographs, then spend the afternoon in the field visiting several sites of glacial geological interest in the Grand Marais area and up the Gunflint Trail. Instructor JD Lehr has spent years mapping and researching the glacial geology of Minnesota and knows the North Shore like, well, the back of his hand. Inquire no more: you’ll be the geology expert on your next group excursion.
