Near Grand Marais in Cook County, Minnesota — The American Midwest (Upper Plains)
Geology of Minnesota
When Newton H. Winchell, Minnesota's state geologist, and, Ulysses S. Grant II (the president’s son) surveyed this area in the 1890s, they concluded that a peak in the Misquah Hills was the state's highest point. Using an aneroid barometer, they set its elevation at 2,230 feet. Later comers argued that Eagle Mountain, which Winchell and Grant did not measure and which can be seen from the Misquah Hills was higher.
In 1961 a United States Department of the Interior survey team remeasured, using aerial photographs and controlled bench marks. They found Eagle Mountain's elevation to be 2,301 feet, making it Minnesota's highest point. They also determined that the first Misquah Hills peak is surpassed by another, unnamed summit 2,266 feet above sea level, located in section 19 of T63N, RIW, in the same western Cook County area. The state's lowest point is Lake Superior, which has an elevation of 602 feet.
The igneous rock composing Eagle Mountain is as old as the Duluth Gabbro, which geologists estimate at over a billion years in age.
