During the Ice Age about 15,000 years ago, an enormous glacier pushed down from British Columbia and blocked the Clark Fork River in northern Idaho near present day Sandpoint. The glacier functioned as an ice dam creating the largest glacial lake known to have existed, Glacial Lake Missoula. The ice dam broke, triggering a flood of epic proportions. The floodwaters roared through the Clark Fork drainage West of here enroute to the Pacific Ocean, carrying icebergs, large boulders, trees, animals, etc. and perhaps humans. Glacial Lake Missoula filled and emptied over and over again perhaps as much as 100 times over a 2,000 - 3,000 year period. Other evidence of the glacial floods include the ice age floods shorelines (strandlines) on Mt. Jumbo and Mt. Sentinel in Missoula, Montana.
