This is most impressive and makes dendrochronology the main dating method for structures containing oak timber.

The method relies upon the response of trees to the weather during the growing season, which runs from March to October.

For example, the year 1976 had a gloriously hot, long summer with most rainfall arriving in autumn but the trees did not appreciate it and all oaks produced a distinctively narrow ring.Again the summer of 1915 was cold and wet, quite different from 1976, yet the trees also produced a distinctly narrow growth ring.He established a laboratory in the university of Arizona, at Tucson, to study tree-rings.Unfortunately, after many years of analysis he was not able to confirm the correlation he sought.Nevertheless, the laboratory was able to demonstrate many interesting properties of ring widths and their relationship with various aspects of climate and other natural phenomena and, of course, their use in the accurate dating of timber.

His laboratory is still one of the leading centres in world dendrochronology.We see this site opens in 0 milliseconds and it is a really good score.
