    The radiocarbon date is in for the Irma canoe, and the mystery continues!
    Radiocarbon dating is a reliable method, but sometimes it can lead to more questions than answers. Radiocarbon dating does not produce a single date but rather a range of dates with associated probabilities.
    The radiocarbon dating results for the Irma canoe returned three date ranges with associated probabilities. There is a 50 percent probability the wood used to make the canoe dates between 1640 to 16...

    Received some good news today. A Dendrochronology test was approved for the canoe!
    Dendrochronology is the formal term for tree-ring dating, the science that uses the growth rings of trees as a detailed record of climatic change in a region, as well as a way to approximate the date of construction for wooden objects of many types.
    As archaeological dating techniques go, dendrochronology is extremely precise: if the growth rings in a wooden object are preserved and can be tied into an existing chronology, researchers can determine the precise calendar year--and often season--the tree was cut down to make it.
    Because of that precision, dendrochronology is used to calibrate ​radiocarbon dating, by giving science a measure of the atmospheric conditions which are known to cause radiocarbon dates to vary. it.
