This was the higher viewpoint we hiked to. A little different view of the Falls area including the power plant on left.
The Bonneville Flood- An Ancient Lake Dies, A Canyon Grows
About a million years ago, a gigantic lake about the size of Lake Michigan, covered roughly 20,000 square miles of northern Utah, eastern Nevada and southern Idaho. Lake Bonneville was formed by a natural rock barrier at Red Rock Pass in eastern Idaho but had no river outlet to the sea.
Approximately 11,000 years ago-yesterday in geological terms-rainfall and snowmelt gradually raised the level of the lake until the natural dam collapsed. The entire lake came crashing through the Snake River Canyon, causing the Great Bonneville Flood.
