If the method had a large component of random error due to inaccurate pattern matching, how could such detailed agreement between the radiocarbon in the rings of two independent dendrochronologies be possible? In addition, particular tree-species may present "missing rings", and this influences the selection of trees for study of long time-spans. Tree-ring chronologies have been extended to 10, years before present in this way. However, they did agree with the bristlecone chronology as far back as it could be checked by the shorter chronologies. In all cases, the number of rings affected is grouped around 51 or 96 rings. It can be anchored by cross-matching a section against another chronology tree-ring history whose dates are known. If trees were growing two or three rings per year at the time one of these episodes occurred, two or three times as many rings would be affected than if trees were only growing one ring per year. They are deciduous, grow relatively rapidly, at low altitudes, in relatively warm, moist environments, and live for only hundreds of years. On the other hand, past cultures that communicated information orally have left us few sources useful for climatic reconstruction, and when piecing together the climatic shifts that affected such civilizations we must depend on, for example, tree ring data. But another independent check came along which was even better than the Douglas fir chronology.
