In the late 1970s Chip Ward and his wife left the Sleeping Rainbow Ranch in Capitol Reef National Park to raise their children in the classic small-town American setting of Grantsville, Utah. There, on the edge of the Great Basin Desert, disturbing tales of local sickness and death interrupted an idyllic life. A seven-year quest to understand a hidden history of ecocide followed. Canaries on the Rim is Ward’s firsthand account of that quest and how lessons learned in the wilderness were later applied to building opposition to toxic waste disposal, chemical weapons incineration, industrial pollution, and nuclear waste storage.
