Strong Verbs Are Just Better

Unrelated to anything romance-novel-y here (although boo unconvincing portrayals of academia), I have questions about the terminology of "Olympic Strait." Do they call it that in the book, as opposed to the Juan de Fuca strait/more properly these days the Salish Sea? Please do tell! While I cannot see the strait in question and the Olympic Peninsula on the other side of it from my house, I can of course see it from a ten-minute walk down the road, so this is relevant to my interests. I require further discussion/evidence to figure out if this is an alternative name for it in Washington State!
