A multidisciplinary Science Advances study details Shég' Xdaltth'í' in interior Alaska, where the earliest occupation dates to about 13,800 years ago. A post stain, hearth and small pit form a potential dwelling area, while a nearby earth oven held charcoal and animal bone. Bone-needle fragments, an antler pendant, stone tools and tens of thousands of artifacts show repeated family life, cooking, sewing and toolmaking. Obsidian came from hundreds of miles away, and diamond-shaped bifaces resemble western Beringian technologies while also connecting with early traditions south of the ice sheets. The researchers describe one of North America's earliest potential habitation structures, while the exact dwelling form and possible dog domestication remain cautious interpretations of the evidence assemblage.
