Big Thompson Canyon Flood
Today is the 30th anniversary of the Big Thompson Canyon Flood. It was Colorado's worst natural disaster. A thunderstorm stalled near Estes Park at the head of Big Thompson Canyon. It dumped 14 inches of rain into the narrow canyon. The usual two-foot-high stream turned into a twenty-foot wall of water. It swept 10-foot boulders, cars, campers, and houses through the twisty canyon. 145 people were killed and 418 houses were destroyed.
Because of that disaster, when you ride up each canyon on the east side of the Rocky Mountains, you will see signs that say "Climb to safety" if the water level rises rapidly. One more thing to pay attention to when riding.
