Chart 18007 San Francisco to Cape Flattery. Note that at 41-28 N and 124-54 W there is a 331 fathom (2000 feet) shallow area and that just below and east of there the water is much deeper. Any long period wave arriving from the far Pacific would be parallel to the coast along the entire coast, at this point. Such a wave would be twisted around and funneled towards Crescent City. There is no similar structure along the US West Coast and it may account for why CC gets hit. The underlying assumption is that the waves that have caused damage at CC were of such a length that they would be focused by such water depths as exist in this area. The wave length involved can't be much more than 30-50 miles at these water depths, I would estimate. I don't think this proves the case, but the possibility is intriguing.
