Over the Edge: Death in Grand Canyon

Every recorded death in Grand Canyon National Park, sorted by how it happened: falls from the rim, dehydration on the trails, flash floods, the Colorado River, air crashes, freak accidents, suicides and murders. Michael Ghiglieri is a biologist who has run the river for decades and Thomas Myers is a doctor who has treated hundreds of the injuries; each chapter closes with a dated list of names and causes. They are blunt about the pattern: most of these people made the same small, avoidable decisions.
