Many other industries are of prime economic importance. About two-thirds of all the iron ore mined in the United States comes from Minnesota. The lumber industry still flourishes, furnishing raw materials for making pulp, paper and other products. Additional goods and services include cereals, chemicals, food mixes, metal products, medical and surgical instruments, printing and publishing. The fishing industry contributes a thriving market.
Fishing also accounts for part of the state's popularity as a prime tourist attraction.
The many species to be found in Minnesota's crystal lakes and streams include walleye, northern pike, muskie, lake trout, brook trout, brown trout, rainbow trout, salmon, largemouth bass, smallmouth bass, crappie, sunfish, catfish and bullheads. There is a wide variety of accommodations for sports enthusiasts, from primitive campsites to developed campgrounds, lodges and resorts. Every cultural attraction is at hand in the metropolitan area of the Twin Cities and in many smaller towns and communities throughout the state. Art galleries and museums, historic buildings and sites are located in cities, picturesque villages and rustic environments of unsurpassed scenic splendor. Duluth on Lake Superior in northeastern Minnesota is a wonder of its own, with dozens of interesting places and attractions to be experienced by car, bus, boat or on foot.
