The Aleutian Tradition began around 2500 BC and ended in AD 1800. Aleutian artifacts are made out of chopped stone, unlike the more common slate tools. Objects were traditionally made using a concept called core and flake that uses bifacially carved projectile points. The Aleutian people lived in semi-subterranean winter houses made from driftwood, whale bone, and peat. They used kayaks, atlatls and harpoons to kill sea mammals for sustenance. Around 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 sustenance pattern changed from relying on sea mammals to eating mostly salmon. Long-distance trade also started increasing community with other local groups. rdf:langString
