Thule people
Old Bering Sea stage, 200 BC to AD 500

A strong maritime adaptation is characteristic of the Thule, and the OBS stage, and then can be seen in the archaeological evidence. Both Kayaks and umiaks (large skinned boats) appear in the archaeological record for the first time. The toolkits of the people of the time are dominated by polished-slate rather than flaked-stone artifacts, including lanceolate knives, projectile heads, and the ulu transverse-bladed knife. The people also made a crude form of pottery and there was much use of bone and antlers for heads on harpoons, as well as to make darts, spears, snow goggles, blubber scrapers, needles, awls and mattocks, also walrus shoulder-blade snow shovels.
