Late Archaic Stage hunter‐gatherer communities living in the Humboldt Bay, Eel River, and Mad River areas of the Pacific coastland of northwestern North America in the period c.150 bc to recent times. These communities specialized in riverside and coastal locations, relying heavily on seasonal salmon runs and other predictable marine resources. Hunting was also carried out in adjacent uplands. Lithic assemblages of the period include distinctive projectile points of triangular outline with pronounced basal barbs and a central tang. Long‐distance trade allowed the acquisition of obsidian from sources over 400 km away. Cemeteries suggest some ranking among Gunther communities.
