Is there an allure of spoiled places? Spoil islands are overlooked places that combine dirt with paradise, waste-land with ';brave new world,' and wildness with human intervention. Although they are mundane products of dredging, these islands form an uninvestigated archipelago that demonstrates the potential value and contested re-valuation of landscapes of waste. To explore these islands, this book navigates a course along the U.S. east coast, moving from New York City to Florida. Along the way, a general populace squats, picnics, and reflects on the islands, while other forces are also at work. New York City parks commissioner Robert Moses first deplores then adopts Hoffman and Swinburne Islands, UN Secretary General U Thant meditates on the East River's Belmont Island, businessman John D. MacArthur rejects the purchase of Peanut Island, artist Christo surrounds Miami's spoil islands, Key Westers debate the futures of two spoil islands that mark their sunset view, and artist Robert Smithson augments this archipelago materially and conceptually. Historical and contemporary stories highlight each island's often contradictory ecologies that pair nature with infrastructure, public concerns with private development, rationalized urbanism with artistic impulse, and order with disorder. Spoil islands put you in places you normally wouldn'tand perhaps shouldn'tbe. To examine these marginalized topographies is to understand emergent concerns of 21st-century place-making, public space, and natural and artificial infrastructure. Today, spoil islands constitute an unprecedented public commons, where human agency and nature are inextricably linked.
