Minnesota Resources
Minnesota covers 79,610 square miles (2.25% of the United States). It is famous for its lakes, having in excess of 15,000, depending on the source of the count. Much of the state is flat, having been eroded during repeated glacial periods (most recently the Wisconsin Glacier). However, the extreme southeastern portion of the state is part of the Driftless Zone, which was not glaciated, and it is here that Lake Pepin and the rugged high bluffs of the Mississippi River are found. In addition, the Iron Range and other low mountains are found in the northeastern part of the state. The Minnesota portion of Lake Superior is the largest body of water in the state. Minnesota is home to many areas of park land, to the Boundary Waters Canoe Area Wilderness (BWCAW), as well as a number of state and county parks, most notably Itasca State Park, the official source of the Mississippi River. After its rivers and lakes, Minnesota's most prominent physical feature is the Iron Range. This is a range of low mountains that run across the northern part of the state. It is called the Iron Range because when discovered, it had some of the largest deposits of iron ore in the country. Although the high-grade iron ore was mostly mined out during World War II, taconite is still mined across the Iron Range.
