Milwaukee heritage, its glass skywalk system, and the Milwaukee Riverwalk. Milwaukee lies along the shores and bluffs of Lake Michigan at the confluence of three rivers: the Menomonee, the Kinnickinnic, and the Milwaukee. Smaller rivers, such as the Root River and Lincoln Creek, also flow through the city. Milwaukee's terrain is sculpted by the glacier path and includes steep bluffs along Lake Michigan that begin about a mile (1.6 km) north of downtown. In addition, southwest of Milwaukee is the Kettle Moraine and lake country that provides an industrial landscape combined with inland lakes. According to the United States Census Bureau,

By 1960, Milwaukee had grown to become one of the largest cities in the United States. Its population peaked at 741,324. In 1960, the Census Bureau reported city's population as 91.1% white and 8.4% black. By the late 1960s, Milwaukee's population had started to decline as people moved to suburbs, aided by federal subsidies of highways. They
