Tree-Ring Circus
Well, tree-ring dating, or dendrochronology, can be this precise, and even more so. Dendrochronologists showed that an ancient wooden road uncovered in southwestern England not only was built in 3806 B.C., but that the trees used for the road were chopped down in the winter of that year (the winter of 3807-3806). The science can also reveal the origin of old pieces of wood. In one case, archeologists determined not only the age of a Viking ship found in Denmark, they also learned that it was built in Ireland."
The above quote from a NOVA page, this subject turns out to be much more complicated and detailed than just measuring the width of the rings, which is all I thought there was to it. See NOVA's treatment of it, and build your own tree ring right here.
