Moose Mountain SNA, A Late Summer Hike in the North Shore Highlands
Moose Mountain SNA in Duluth is a bedrock ridge "held up" by an underlying erosion-resistant diabase sill, formed by intrusion of magma between pre-existing rock layers. At its peak, the mountain rises nearly 550 feet above the elevation of Lake Superior, which is less than a mile away as the crow (or raven) flies.
