Prehistoric Alaska begins with Paleolithic people moving into northwestern North America sometime between 40,000 and 15,000 years ago across the Bering Land Bridge in western Alaska; a date less than 20,000 years ago is most likely. [1]
1000 BC: Athapaskan-speaking natives arrive in Alaska and northwestern North America, possibly from Siberia. 1000 BC: Pottery making widespread in the Eastern Woodlands. 1000 BC–100 AD: Adena culture takes form in the Ohio River valley, carving fine stone pipes placed with their dead in gigantic burial mounds.

The oldest human skeletal remains are the 40ky old Lake Mungo remains in New South Wales, but human ornaments discovered at Devil's Lair in Western Australia have been dated to 48 kya and artifacts at Madjedbebe in Northern Territory are dated to at least 50 kya, and to 62.1 ± 2.9 ka in one 2017 study.

The history of Alaska dates back to the Upper Paleolithic period (around 14,000 BC), when foraging groups crossed the Bering land bridge into what is now western Alaska. At the time of European contact by the Russian explorers , the area was populated by Alaska Native groups.
It is located on the Pacific coast of Katmai National Park and Preserve, in the mainland portion of Kodiak Island Borough, Alaska. The most important site in the bay is on Mink Island, which contains evidence of human habitation from 7,300 to 500 years ago, and is one of the oldest known places of human habitation on the Alaska Peninsula.
Warmer, ice-free conditions in the southeast Bering Sea are roughly 200 times more likely now than before humans began burning planet-warming fossil fuels. Scientists have more evidence to explain ...
