Topic: geology et al
Interesting geological aspects of the Gunflint Trail: the trail cuts across several belts of various rocks including lava flows where gabbro and red rock granite can be observed. There is a conspicuous boulder bed. The finer glacial drift has been washed away leaving the bigger rock. Granite, being resistant to erosion, is seen as outcroppings in the form of hills. One is 2230 feet above sea level, the highest point in the state. A lot of the lakes are longitudinal because that's the direction the glaciers gouged out depressions, from west to east. I suppose this is pretty boring to most people.Hoffs Rock Shop
