Dendrochronology is, of course, the method of using tree rings to date things. Our records go back as far as 11,000 years in some cases, which is incredibly useful for archaeological purposes and as a side effect also demonstrates that such dates existed to boot – you can see how that might worry young Earth creationists. For his October Acts & Facts article John D. Morris wants to talk about Tree Ring Dating and its problems.
Several species of trees live almost indefinitely. The giant sequoia trees of California are known to live over 3,000 years, discerned through tree ring dating. Under normal circumstances, woody trees add one ring per year. A ring typically consists of a light-colored growth portion and a dark-colored portion produced in a stabilization season. However, some trees do not produce annual rings at all, especially those in temperate or tropical regions.
Actually, it is those that are in temperate regions that produce the best rings, as the seasonal changes in growth are the clearest. Morris needs to show us that dating via this method is unreliable. You’ll note the lack of specifics on his part. Continue reading
