A memoir-meets-expose that examines our fraught relationship with the West and our attempts to clean up a toxic environmental legacy In 2002, Texas journalist Brad Tyer strapped a canoe on his truck and moved to Montana, a state that has long exerted a mythic pull on America's imagination as an unspoiled landscape. The son of an engineer who reclaimed wastewater, Tyer was looking for a pristine river to call his own. What he found instead was a century's worth of industrial poison clotting the Clark Fork River, a decades-long engineering project to clean it up, and a forgotten town named Opportunity. At the turn of the nineteenth century, Montana exploited the richest copper deposits in the world, fueling the electric growth of twentieth-century America and building some of the nation's most outlandish fortunes. The toxic by-product of those fortunes-what didn't spill into the river-was dumped in Opportunity. In the twenty-first century, Montana's draw is no longer metal but landscape- the blue-ribbon trout streams and unspoiled wilderness of the nation's "last best place." To match reality to the myth, affluent exurbanites and well-meaning environmentalists are trying to restore the Clark Fork River to its "natural state." In the process, millions of tons of toxic soils are being removed and dumped-once again-in Opportunity. As Tyer investigates Opportunity's history, he wrestles with questions of environmental justice and the ethics of burdening one community with an entire region's waste. Stalled at the intersection of a fading extractive economy and a fledgling restoration boom, Opportunity's story is a secret history of the American Dream and a key to understanding the country's-and increasingly the globe's-demand for modern convenience. As Tyer explores the degradations of the landscape, he also probes the parallel emotional geography of familial estrangement. Part personal history and part reportorial narrative,Opportunity, Montanais a story of progress and its price- of copper and water, of father and son, and of our attempts to redeem the mistakes of the past.
