Grand Marais in Cook County, Minnesota — The American Midwest (Upper Plains)
Geology of Minnesota
Grand Marais
To the west of Grand Marais, the serrated crest of the Sawtooth Range, clearly visible from the harbor breakwater, is another example of unequal erosion. Here the relatively soft basalt and the more resistant diabase have, through the process of weathering, produced the notched profile of the hills along the coast.
To the east of Grand Marais rise the hills near the mouth of the Arrowhead River, while to the north, along the Gunflint Trail, are older rocks. At Saganaga Lake, the Saganaga granite, one of the oldest granites in North America, marks a core of the ancient mountains of the Laurentian Highlands.
Erected 1955 by the Geological Society of Minnesota and the Department of Highways, State of Minnesota aided by a grant from the Louis W. and Maud Hill Family Foundation.
