Bristlecone pine tree ring dating

To this day, there has still never been an older tree discovered. Basically, Currey got his tree corer stuck in the tree. An unwitting park ranger helped him by cutting the tree down, to remove the instrument, and later Currey began to count the rings. Eventually, he realized that the tree he had just felled was almost 5, years old — the oldest tree ever recorded. Great bristlecone pines are some of the longest living trees in the world.

To put the matter simply, the science of Dendrochronology uses tree ring patterns to construct chronologies that not only show the age of trees, but also the climatic conditions in which they grew. According to Wikipedia:. Fully anchored chronologies which extend back more than 11, years exist for river oak trees from South Germany from the Main and Rhine rivers and pine from Northern Ireland. Furthermore, the mutual consistency of these two independent dendrochronological sequences has been confirmed by comparing their radiocarbon and dendrochronological ages. Another fully anchored chronology which extends back years exists for the bristlecone pine in the Southwest US White Mountains of California. As you can easily understand, this is a problem for young-earth creationists.

Creationism and Tree Ring Chronology

By Hunter Oatman-Stanford — November 13th, In , a geologist in the Nevada wilderness discovered the oldest living thing on earth, after he killed it. The young man was Donald Rusk Currey, a graduate student studying ice-age glaciology in Eastern Nevada; the tree he cut down was of the Pinus longaeva species, also known as the Great Basin bristlecone pine. Working on a grant from the National Science Foundation, Currey was compiling the ages of ancient bristlecone trees to develop a glacial timeline for the region.

Objective To learn how scientists determine the age of living and non-living trees. Tell students they will be taking on the role of a dendrochronologist, a tree-ring scientist. Provide each student with two copies of the "Tree-Ring Science" student handout. Students will be crossdating tree-ring samples to determine which sample is oldest, and will then determine the age of the oldest sample. This works by comparing the patterns in the tree-ring samples obtained from trees in the same region that have experienced similar weather conditions.
