A thawing historical archive
Across the vast expanse of Arctic Siberia, rising temperatures are thawing the permafrost, the perennially frozen ground that covers about two-thirds of Russia. This process reveals an immense and fragile archaeological record. For millennia, the cold, low-oxygen conditions of the permafrost have preserved organic materials that would decay elsewhere. As the ground softens, it exposes everything from ancient hunting equipment and textiles to the remains of extinct Pleistocene megafauna. Scientists now face the challenge of discovering and preserving these materials before they are lost to microbial decomposition.
One significant location is the Ust-Polui site, near the modern city of Salekhard, occupied between roughly 260 B.C. and A.D. 140. Permafrost at this Iron Age sanctuary preserved a remarkable collection of artifacts, including parts of complex sleds and dog harnesses. The remains of at least 128 dogs have been identified at the site, providing information on the history of dog domestication and their use in transportation and ritual sacrifice. Another important site is Mangazeya, the first Russian polar city, founded in 1601. Excavations at this 17th-century trading post have yielded thousands of well-preserved items, including leather shoes, clothing, wooden tools, and one of the largest archaeological collections of chess pieces in Russia.
