Book excerpt: Minneapolis began at the Falls of St. Anthony, the sole waterfall on the Mississippi River. The cataract, the great hydrological engine, propelled the city's economic growth and physical expansion, and two distinct municipal identities emerged. A city of seasons, Minneapolis celebrates winter flurries and chills with ice skating and hot chocolate at the annual Holidazzle Festival. In the sultry midsummer heat, the Aquatennial brings swimmers and boating enthusiasts to the Chain of Lakes and the river. Landmarks, too, define the topography-Spoonbridge and Cherry, the Stone Arch and Hennepin Avenue Bridges, the Foshay Tower and the IDS Center. Join local authors Sherman Wick and Holly Day on a trip beyond the typical guidebook as they explore the architecture, parks and historical figures of the Mill City.
