Snohomish County iis located in northwest Washington State, nestled between the sparkling blue waters of Puget Sound and the rugged, snow-capped peaks of the Cascade Mountains. Snohomish County begins 12 miles north of Seattle, a little under 100 miles south of Vancouver, and a short ferry ride away from the San Juan Islands or Olympic Peninsula. Snohomish County is ideally situated for exploring the entire Pacific Northwest. The county seat and largest city is Everett. The county was created out of Island County on January 14, 1861 and is named for the Snohomish tribe. "Indians named rivers and areas after their own tribes. The dominant tribe in this county was the Snohomish, the Indians spelling it 'Sdoh-doh-hohbsh.' Although many historians debate the meaning or claim it had none, Chief William Shelton, last of the hereditary Snohomish chiefs, said it meant lowland people. Other students of Indian lore say it might mean 'a style of union among them' of 'the braves'. Other sources claim the name means 'Sleeping Waters'. Still other spellings have given Sdohobich."
