The Ice Age Lake Missoula Floods affected four states and left much evidence of their passing. Most dramatic are the scablands of eastern Washington. With few exceptions all other books on the subject stop at the west end of the Columbia River Gorge. GigaFlood reveals the effects of the largest Lake Missoula Flood in northwest Oregon and southwest Washington with photos, maps and illustrations. This much neglected area has more subtle features from these floods that inundated the Portland/Vancouver area, Willamette and other valleys with up to 400 feet of water. GigaFlood shows you where to find the ice-rafted erratics, giant current ripples, huge gravel bars and flood channels that were a result of these cataclysms.
