I have read/heard that many of the tribes down the Columbia river have flood stories as well. It is interesting to hike up to where the water line was. You can clearly see it in the rimrock and hills/mountains around Coeur d'Alene/Spokane. Missoula is even more pronounced with the lake rings. You can stand on Chilco Peak and look west it is all flat and filled in up to a certain point with aggregate (lots of gravel, great aquifer) and you look east and it looks like typical mountain valleys. The ridges nearby formed the barrier to the flow. edits: add more info
