Tree ring dating oldest
Before you dismiss, please consider making a donation. If, in fact, the oldest tree is 4300 years old, so what? Hovind is impressed by the fact that such a tree would have sprouted at about the time Noah's flood ended.
The technique can date wood to exact calendar years, and tell much about the climate of specific years.The source of tree information that he is using as evidence comes from Wired Science, which compiled a list of 12 ancient, still-living trees.Thomas states that two of the trees are 'clonal trees', which he states have estimated ages based on presumed rates of outward spreading.But for the specimen to be useful in extending the tree-ring chronology, the absolute calendar age of its rings must be determined.The annual growth rings vary in thickness each year depending on environmental factors such as rainfall.The following article is abstracted from The Biblical Chronologist Volume 5, Number 1. The science of constructing chronologies from tree rings is called dendrochronology. Modern trees are known to produce one growth ring per year. (The idea that ancient trees grew more than one ring per year will be discussed below.) Therefore, by coring a living tree and counting rings from the present backwards, it is possible to determine the year in which each ring grew. The bristlecone pines in the White Mountains of California live to extremely old ages, some in excess of 4,000 years.
The University of Arizona dendrochronology lab sports a (no longer living) specimen which contains over 6,000 rings.
By matching ring-width patterns in a specimen of known age (starting with living specimens) to ring-width patterns in an older specimen, the proper placement of the older specimen is determined.
Tree-ring chronologies have been extended to 10,000 years before present in this way.
It might interest you to know that trees go back at least 8000 years without being disturbed by Noah's flood! Charles Ferguson of the University of Arizona has, by matching up overlapping tree rings of living and dead bristlecone pines, carefully built a tree ring sequence going back to 6273 BC (Popular Science, November 1979, p.76).
It turns out that such things as rainfall, floods, glacial activity, atmospheric pressure, volcanic activity, and even variations in nearby stream flows show up in the rings.
We could add disease and excessive activity by pests to that list.
