Central Minnesota is the central part of the state of Minnesota. No definitive boundaries of the region exist, but most definitions would include the land north of Interstate 94, east of U.S. Highway 59, south of U.S. Highway 2, and west of U.S. Highway 169. Geography The northern part of the region contains many softwood forests, including the expansive Chippewa National Forest. The western and southern parts are dotted with rolling prairie, and have the region's largest agricultural operations. The region's eastern part has many hardwood and softwood forests, and once had rich iron ore deposits. The now depleted Cuyuna Range, which formed the southwestern border of the large Iron Range, was near Crosby and Ironton, at the region's eastern edge. One thing all of central Minnesota has is abundant lakes. A typical image of central Minnesota includes the many large and small lakes that surround the cities of St. Cloud (by far the region's largest city), Alexandria, Brainerd, and other settlements. Two lakes in the region, Mille Lacs Lake, with an area of 206 mi² (534 km²), and Leech Lake, with an area of 175 mi² (453 km²), are, respectively, the second- and third-largest lakes entirely within Minnesota. The Mississippi River winds extensively through the region from its source at Lake Itasca. Area high school athletic conferences acknowledge the region's location and natural geography with names including Central Lakes, Granite Ridge, Great River, Heart O'Lakes, Mid-State, and Pine to Prairie. Economy Central Minnesota's economy, like that of the United States as a whole, has recently shifted away from agriculture and mining toward industry and service. But agriculture is still important in the region, especially the southern and western parts, where the land and soil is conducive to crops such as corn and soybeans. Dairy farms also dot the region in areas where crops cannot easily be grown, but their numbers have been drastically dwindling in recent years. Paper companies own expansive amounts of land in the region's heavily forested eastern and northern parts, but logging activity has long since peaked. Paper production mills continue to operate in Brainerd and Sartell. Tourism has become an important industry in the region in the last few decades, fueled largely by its lakes. Many of the region's cities see their populations swell in the summer, when people from the larger metropolitan areas of Minneapolis/St. Paul, Duluth, Fargo, and Grand Forks come to enjoy
