dendrochronology

Method of scientific dating based on the analysis of tree rings. Because the width of annular rings varies with climatic conditions, laboratory analysis of timber core samples allows scientists to reconstruct the conditions that existed when a tree’s rings developed. By taking thousands of samples from different sites and different strata within a particular region, researchers can build a comprehensive historical sequence that becomes a part of the scientific record. Such master chronologies are used by archaeologists, climatologists, and others.

The theory was apparently disproven recently when an dendrochronologist determined the tree predates Lewis and Clark, lending credence to the other theory: it was planted by Native Americans who valued the flexible wood for its value as hunting bows.
