Book excerpt: Water Gold Soil: The American River tells the story of a single flow of water in present-day California from origin to end use. Beginning at the river's headwaters in the Sierra Nevada mountain range, the book follows the water through pipes and dams, past Sutter's Mill and the birthplace of the Gold Rush, to the corporate agricultural fields until it eventually disappears into the ground, finding veins in the soil. Including a short essay by Elizabeth Kolbert, the book brings together a series of narrative text, photographs, and archival images that represent the history of extraction in California and testify to the social and ecological consequences of watershed colonialism.
