The Snohomish River Valley was originally inhabited by the Snohomish people, a Coast Salish tribe who lived between Port Gardner Bay and modern-day Monroe. An archaeological site near the confluence of the Snohomish and Pilchuck Rivers has indications of human habitation that began as early as 8,000 years before present.
