Archaic Stage, coastally adapted communities of the San Francisco Bay area of the American west coast between ad 600 and recent times. These groups lived in small villages, exploiting the coastal marshlands for fish and shellfish, while also using a wide range of edible plants, especially acorns. Small side‐notched points were probably arrow tips; barbed bone spears were used in fishing. Burials were usually by cremation, any grave goods, mainly ornaments and beads, being burnt too. Hotchkiss communities are regarded as ancestral to the Wintum, Miwok, and Yokuts who occupied central California at the time of European contact.
