Riverside Plaza is a modernist and brutalist apartment complex designed by Ralph Rapson that opened in Minneapolis, Minnesota in 1973. Situated on the edge of downtown Minneapolis in the Cedar-Riverside neighborhood, and next to both the University of Minnesota's West Bank and Augsburg University, the site contains the 39-story McKnight Building, the tallest structure outside of the city's central business district. Initially known as Cedar Square West, exterior shots of the complex were featured on television as the residence of Mary Richards in sixth and seventh seasons of "The Mary Tyler Moore Show". [SEP] Knowledge 3: Minneapolis
Minneapolis lies on both banks of the Mississippi River, just north of the river's confluence with the Minnesota River, and adjoins Saint Paul, the state's capital. The city is abundantly rich in water, with 13 lakes, wetlands, the Mississippi River, creeks and waterfalls; many connected by parkways in the Chain of Lakes and the Grand Rounds National Scenic Byway. It was once the world's flour milling capital and a hub for timber. The city and surrounding region is the primary business center between Chicago and Seattle. As of 2018, Minneapolis was home to 6 Fortune 500 companies, and the Twin Cities were the fifth-largest hub of major corporate headquarters in the United States. As an integral link to the global economy, Minneapolis is categorized as a global city. [SEP] Knowledge 4: Mississippi River

The basin covers more than 1,245,000 square miles (3,220,000 km), including all or parts of 31 U.S. states and two Canadian provinces. The drainage basin empties into the Gulf of Mexico, part of the Atlantic Ocean. The total catchment of the Mississippi River covers nearly 40% of the landmass of the continental United States.
