The Morrison Mine is an open pit iron mine in the Mesabi Range, Itasca County, Minnesota. The Mine shipped ore starting in 1929 and produced into the 1950s. It later operated as part of the Walker Group of mines. The Oliver Iron Mining Company was organized in 1892 and acquired a number of mineral properties in Minnesota and in the Upper Peninsula. By 1901 the Company was a division of United States Steel Corporation.
