The Lake was called Humongous Lake Missoula. It was filled (and emptied) dozens of times during the ice age as the glaciers would first block the water, then collapse and flood what is now Spokane and eastern Washington state. This factoid is courtesy of Mountain Press, Missoula, Mt. and points west.
