The Mississippi National River and Recreation Area is a 72-mile river park offering fishing, boating, canoeing, birding, bicycling, and hiking along the Mississippi, where millions of people visit each year and 40 percent of all North American waterfowl and 326 bird species use the river as a migratory flyway. Between the Twin Cities, St. Paul developed around shipping and transportation, while Minneapolis, powered by lumber and flour mills at St. Anthony Falls, became an industrial giant, and by the mid-19th century the cities' social differences and destinies were firmly established. The area includes places such as the John H. Stevens Interpretive House, Historic Fort Snelling, St. Anthony Falls, and Lock and Dam No. 1, where locks and dams made navigation to Minneapolis feasible after natural rapids had long made it nearly impossible. Ramsey, named for Minnesota's first territorial governor, Alexander Ramsey, embraces its natural resources, with half the city bordering the Mississippi and Rum Rivers, more than 15 percent of its land protected wetlands, and several hundred acres of parks, greenways, and public open space supporting recreation, water conservation, and wildlife habitat. The 72-mile recreation area begins at the confluence of the Crow River in Ramsey/Dayton and flows south to the confluence with the St. Croix River, making Ramsey a northern gateway to this national park, the Mississippi River Trail, and the Metro Mississippi Great River Road Destination Area. The Rum River, known to the Dakota as Watpa waķaŋ or Spirit River, flows 150 miles from Mille Lacs Lake to the Mississippi and was an important fur trade route in the 17th and 18th centuries before carrying millions of logs to Twin Cities sawmills by the late 19th century. In Ramsey, the Mississippi River Trail welcomes bicyclists with both short loops and longer trips, including on-road segments for experienced riders and off-road paths and trails suitable for riders of all abilities.
