For more than 10,000 years, the Sammamish people have hunted, fished, and gathered on their lands along Lake Washington and the Sammamish River and Lake.
They [Sammamish People] are indigenous to the Sammamish River Valley in central King County, Washington.
The Sammamish speak Lushootseed, a Coast Salish language which was historically spoken across most of Puget Sound, although its usage today is mostly reserved for cultural and ceremonial practices.
