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.

Because of the distortions and lies spread by fundamentalists about scientific dating there is a need for a centralized source of information on the topic.

A few examples of such lies are presented at the very bottom of this page.

He concludes that my reinterpretation is invalid because the timescale has been corroborated by up to three independent annual measuring methods that agree with volcanic acidity spikes and deep-sea cores: β€˜The first 110,000 annual layers of snow in that ice core (GISP2) have been visually counted and corroborated by two to three different and independent methods as well as by correlation with volcanic eruptions and other datable events.’ However, contrary to what Seely believes, neither the annual layer counting methods nor the external correlation methods are independent, they are all tied to the same starting assumptions of deep time.

The 110,000 annual layers are based on the assumptions that the Greenland Ice Sheet has been in equilibrium for several million years and that ice ages oscillate between glacials and interglacials with a period of 100,000 years based on the astronomical theory of the ice age (the Milankovitch mechanism).

Ice core sampling normally uses the assumption that the ring bands observed represents years.

It and the Acheulean toolkit were made for an immense period of time – ending in different places by around 400,000 to 250,000 years ago.

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.

Generally, it is not possible to construct a complete sequence of tree rings back through the historical periods using only living trees.

Chronologies derived from living trees must be extended.
