Description: Bubbling cumulonimbus cloud over Mitchell Lake on the day of the Big Thompson flood, July 31, 1976. The massive thunderstorm that followed the formation of these clouds dumped more than 12 inches of rain in a four-hour period, sending a wall of water more than 20 feet high through Big Thompson Canyon. 143 people died in one of Colorado's worst natural disasters.
