— Explore a wealth of archaeological digs in the Arctic with FrontierScientists, including Raven Bluff, site of a 12,000 year old prehistoric hunting camp overlooking the Kivalina River in Alaska yielding generations of evidence beginning at a time when the Arctic was a drier, grassier landscape grazed by animals including steppe bison. The Bering Land Bridge between Russia and North America may have still existed or may have just submerged for the last time when wandering hunters first frequented Raven Bluff. What archaeologists discovered is contributing new insights–and contrary new evidence–to the thinking on how humans spread throughout North American at the close of the Pleistocene, and the way we’ve lived since then.
