The Snokomish were a Halkomelem-speaking Coast Salish people whose territory was primarily located across the Boundary Bay area.
[1] Closest to modern day Point Roberts, Washington and Crescent, BC.
The Campbell River lets out to the ocean at the Semiahmoo First Nation's reserve lands--very close to today's city of White Rock, British Columbia.
The population was decimated by a smallpox epidemic in 1850, and thereafter some individuals were absorbed into the neighbouring Semiahmoo, whose territory was immediately to the south, and who absorbed the saltwater portion of Snokomish territory (the rest is now Kwantlen territory).
Families with Snokomish heritage among the Semiahmoo retain hereditary rights to the mouths of the Nicomekl, Serpentine and Campbell Rivers.
