Ron, I've been thinking and wondering the same. I have a hunch this past week's news helicopter crash may have something to do with that. I had heard KING 5 news shared KOMO 4's helicopter. I don't know about the other news channels though, I think KIRO 7 has one, but maybe they've been grounded for the time being. No doubt, aerial coverage would provide us all the visuals to get the full magnitude of this thing. I too was surprised to realize that it was the hill on the north side of the valley that slid, damned the river and continued south to cover the housing development, and carried on to bury the entire highway on the other side of the valley!
