Essentially what is the most practiced principle is comparing dates of tree-ring series from one tree to many other trees from a different location.

Once tree rings from one general area are compared with corresponding patterns observed in another area it is compiled as a set of data and crossdating has been achieved.

Please check back as more information becomes available, and we look forward to seeing our tree-ring colleagues from around the world in Thimphu the summer of 2018!

Dendrochronology (also called tree-ring dating) is a technique of dating past climatic changes through a study of tree ring growth.

Each year a tree adds a layer of wood (xylem) to its trunk and branches thus creating the annual rings we see when viewing a cross section.

Wide rings are produced during wet years and, narrow rings during dry seasons.

As well as one of the founders of the modern creation science movement, Walter Lammerts, who documented in the lab that trees can also display extra rings in short drought periods.

There are seven dendrochronological principles that contain certain assumptions, that are used as a framework or theory to interpret tree-ring data.

The most prominent of such assumptions, uniformitarianism is also an assumption that is quite prevalent within evolutionary science.
