On September 1, 1894, two forest fires converged on the town of Hinckley, Minnesota, trapping more than two thousand people. The fire created its own weather, including hurricane-strength winds, bubbles of plasma-like glowing gas, and 200-foot-tall flames. As temperatures reached 1,600 degrees Fahrenheit, the firestorm knocked down buildings and carried flaming debris high into the sky. Two trains-one with every single car on fire-became the only means of escape. In all, more than four hundred people would die, leading to a revolution in forestry management and the birth of federal agencies that monitor and fight wildfires. A spellbinding account of danger, devastation, and courage, Under a Flaming Sky reveals the dramatic, minute-by-minute story of the tragedy and brings into focus the ordinary citizens whose lives it irrevocably marked.
