Admiralty Inlet

On the bridge of a massively expensive and modern warship sits a well used and carefully annotated nautical chart of the immediate vicinity.

Admiralty Inlet is the channel in purple separating Whidbey Island and the Olympic Peninsula.  All marine traffic to the Port of Seattle, the Port of Tacoma, and the Everett, Bangor, and Bremerton naval bases pass through this 4 mile wide channel.
