Channeled Scablands and Central Oregon
The channeled scablands are an area of central Washington that were flooded dozens of times during the last ice age (which began 3 million years ago) by a glacially-dammed lake bursting out and engulfing the entire central Columbia River basin in hundreds of feet of rushing water. The erosional power was phenomenal. The water stalled as it tried to fit through the Wallula Gap on the Columbia River, however, and an enormous lake formed for about a week as the water flowed through it.
