Oak Harbor grew around the sea, with Maylor Wharf, built in 1893, serving a waterfront where logging dominated the 1800s and tall ships carried island logs worldwide, followed in the 1900s by daily steamships of the Puget Sound Mosquito Fleet loading passengers, freight, and farm products as farming and shipping shaped island life. Major changes came in 1935 with the opening of Deception Pass Bridge and in 1941 when the Navy established the PBY Seaplane Base and Ault Field, transforming the economy. At Maylor's Point, the remains of the old wharf still survive offshore, and the hulk of the steamer Whidby lies on the bottom where it drifted and burned in 1911; nearby, a 1920 fire destroyed Byrne Wharf and part of Old Town, after which the business district rebuilt farther west. Oak Harbor also retains remnants of the Garry Oak savannah that gave the town its name, with some large oaks estimated at 150-300 years old. The shoreline itself changed greatly when the Navy dredged Oak Harbor Bay in 1942 and the city dredged again in 1968 for a marina later moved southeast, using the spoil to fill a swampy lowland for a shore-side street; the resulting rocky fill inspired the names Flintstone Freeway and Flintstone Park, where a local businessman built a stone car.
