Welcome and thank you for visiting the Science of Tree Rings web pages, designed to be the ULTIMATE source for information on the science of Dendrochronology.
I've designed these pages to be easily understood by people at all levels of education, from elementary school students to high school students, from first grade teachers to college professors.
The size of the rings can also depend on the age of the tree, because as a tree gets older it produces narrower rings as well. Dendrochronology has two uses in archaeology: it can be used to calibrate (correct) radiocardon dates, and it can be used to date things all on its own.
Archaeologists look at other trees of the same species in the area because they have the same ring patterns.
My mission was born from an overwhelming need among dendrochronologists for a permanent repository of information that was free to the public, easily understandable, and as comprehensive as humanly possible.
