Brinnon

History

White settlers began arriving in the area that would become Brinnon, then referred to as both Quogaboos and Ducaboos, in the 1850s. Ewell P. Brinnon, a settler who later became the namesake of the settlement, took a donation land claim in the late 1850s at the mouth of the Duckabush River. In 1891 Brinnon was established when the post office began operations in the settlement. Camp Parsons was founded in 1919 just outside the north end of Brinnon. The camp is the oldest Boy Scout camp west of the Mississippi River.
