Geology Strikes Again

Okay, so you know how in Sleepless in Seattle, they roll the opening credits over a relief map of the USA?  Yeah.  And no shit, there I was, thinking of the vagaries of plate tectonics.  'Twas the angle on the map, y'see.  It showed with amazing clarity just how flat the Midwest is (where it's tectonically relatively quiet), how low the mountains in the East are (passive margin), and how mountainous the West is (active boundary, whole lotta squishing going on). 

I'm sure I'll start thinking of the actual movie here soon...
