The tradition is core and flake tradition using bifacially carved projectile points. The Aleutian people lived in semi-subterranean winter houses made from driftwood, whale bone, and peat. They used kayaks and atlatls and darts to kill sea mammals for sustenence. In AD 1150 Aleutian houses increased considerably in size. Food was stored in special chambers inside the house and weaponry was becoming more common around these sites. The sustenence pattern changed from relying on sea mammals to eating mostly salmon. Long distance trade also started increasing community with other local groups.
