A marine mammal-hunting culture found around the Kachemak Bay of the southern Kenai Peninsula in central southern Alaska. It is divided into three phases, the oldest of which may date back as far as the 8th century BC and the most recent lasting until historic times. The first phase was the most distinctly Eskimo in character. Stone (including slate) implements in the early period were usually retouched; later they were ground. Round or oval stone lamps and realistic human figures of carved stone have been found. Copper tools and pottery appeared in the third stage. Rock paintings were mainly representations of men and animals. Burials have the body in a crouched position, with associated grave goods. During the final stage, artificial bone or ivory eyes were placed over those of the deceased. There may have been cultural connections with eastern Asia, with adjacent land areas, and with Kodiak Island.
