Wine is big business here in Washington and each region vies for attention.  So besides being very cool that geologists can infer a fantastic, complex sequence of events to explain why this place looks like it does; the resulting landscape is claimed to be perfect for red wine grapes.  Fortuitous side benefit I would say!  I have picked up bottles of the signature reds (Cabernet Sauvignon, Syrah, and Merlot) from this region.  I will keep you posted as they are uncorked.
