In this treeless coastal tundra, the primary wood resource is driftwood that come from the boreal forest carried by major interior rivers and ocean currents. While in northern Alaska, some Birnirk and Thule archaeological wood samples can be dated using the rare existing millennial tree ring master chronologies, many come from geographical areas where tree-ring master chronologies are too short (250-300 years). Here, we explore the potential of high-resolution wiggle-matching to accurately date tree-ring series that cannot be dated by conventional dendrochronology and develop preliminary tree-ring chronologies. We present the wiggle-matching results based on 75 radiocarbon dates for eight archaeological timbers from the Piġniq, Rising Whale and Pingusugruk coastal sites in northern Alaska. Wiggle-matching makes it possible to reduce the calendrical interval of these timbers’ last growth ring from centennial to decadal range and position 22 timbers in calendar time. These results open new insights into tree-ring dating of others Birnirk and Thule architectural treering samples and analyzing climatic variations of the early 2nd millennium CE, in different regions of Alaska.}}
