AUGUST 15TH, 1967-The "sundance fire" in northern Idaho was started by lightning. Winds of 50 mph carried firebrands as much as ten miles in advance to ignite new fires, and as a result, the forest fire spread twenty miles across the Selkirk Mountains in just twelve hours, burning 56,000 acres. The heat of the fire produced whirlwinds of flame with winds up to 300 mph which flung giant trees about like matchsticks.
