A chart shows a closeup horizontal view of a sample from a living tree, with rings dating back to about 1916. The rings are matched and overlapped with a sample from a dead/fallen tree underneath that dates back to the 1880s. The living tree sample appears again in a zoomed out just to the right, along with eight specimens taken from dead trees (labelled B to I), matched and overlapped one on top of another, with the earliest dating back prior to 1700. This method can extend the dating back by 1,000 years.
