Dendrochronology is an absolute dating method. In other
words, it is possible to determine not only whether
an event occurred before or after another event, but
also the amount of time that has elapsed between events.
With the same processes you used in this simulation,
archaeologists can identify the precise year in which
a tree was cut to become the beam of an ancient dwelling
or a rancher's fence post. Dates for several Native
American cultures in the southwestern United States
have been established using dendrochronology.
