Tree sliced by chainsaw. Cutting up some storm downed dead fall I was intrigued by the bark and dark core rings of this tree.

Dendrochronology (from δένδρον, dendron, "tree limb"; χρόνος, khronos, "time"; and -λογία, -logia) or tree-ring dating is the scientific method of dating based on the analysis of patterns of tree rings, also known as growth rings. Dendrochronology can date the time at which tree rings were formed, in many types of wood, to the exact calendar year. This has three main areas of application: paleoecology, where it is used to determine certain aspects of past ecologies (most prominently climate); archaeology, where it is used to date old buildings, etc.; and radiocarbon dating, where it is used to calibrate radiocarbon ages.
