The La Crosse River is an 80-mile-long stream that flows into the mighty Mississippi River at the city of La Crosse, Wisconsin (population: about 50,000). This part of the state is called the Driftless Region, because it was never glaciated, so it has bluffs, steep-sided valleys, and wooded streams while most of the Upper Midwest is more flat and more purely agricultural. In early May, birds include residents like the Sandhill Crane, Black-capped Chickadee, and Bald Eagle, as well as summer visitors like warblers, Blue-winged Teal, and American Woodcock. Myrick Park is popular with children, college students, and local residents, and is the site of WisCorps, a sustainable land management and environmental education group.
