They are said to bear similarities with Clovis tools elsewhere in North America – but date somewhat earlier. Not that much earlier but enough to suggest they arrived via the Bering Land Bridge. This is where it gets a bit messy as Beringia, as it has been dubbed, was dry land during the Late Pleistocene. However, it does get rid of the idea they migrated along the frozen ice bound northern hemisphere. It leaves open the idea Alaska itself was largely free of ice during the Late Pleistocene in order for them to arrive on foot – or in a canoe. The new findings may find a way to get around the complications caused by having an extended ice sheet in the Late Pleistocene – affecting all of the area around the pole. The Late Pleistocene scenario is most easily explained by having the North Pole in a slightly different position – and therefore a different polar circle. One that does not include eastern Siberia and Alaska. How that might happen is open to question but that barrier is not necessarily enough to dispute the idea.

The cemetery belongs to the Mesolithic period and had links with similar cultures across NW Europe – including Britain. In general, fur, plant fibres, and other soft organic materials such as feathers, have only been preserved under special conditions. In this instance a new technique developed at the University of Helsinki, can distinguish fibres, hairs, and feather fragments from soil samples taken from graves.
