Island County was created out of Thurston County on December 22,
1852, by the legislature of Oregon Territory, and is the eighth-oldest county in Washington.
It originally encompassed what are now Snohomish, Skagit, Whatcom, and San Juan Counties.
Included in the county are two large islands, Whidbey and Camano, and seven smaller islands: Baby, Ben Ure, Deception,
Kalamut, Minor, Smith, and Strawberry.
The county seat is Coupeville, while its largest city is Oak Harbor.
