During the first half of the twentieth century, the astronomer A. Douglass founded the Laboratory of Tree-Ring Research at the University of Arizona.

Douglass sought to better understand cycles of sunspot activity and reasoned that changes in solar activity would affect climate patterns on earth, which would subsequently be recorded by tree-ring growth patterns (i.e., sunspots → climate → tree rings).

Creationists have shown that the biblical kind is usually larger than the ‘species’ and in many cases even larger than the ’genus’—see my article Ligers and wholphins? Taking this into account would bring the age of the oldest living Bristlecone Pine into the post-Flood era.

Claimed older tree ring chronologies depend on the cross-matching of tree ring patterns of pieces of dead wood found near living trees.

Visible rings result from the change in growth speed through the seasons of the year; thus, critical for the title method, one ring generally marks the passage of one year in the life of the tree.

Removal of the bark of the tree in a particular area may cause deformation of the rings as the plant overgrows the scar.

There are many points in a given sequence where a sequence from a new piece of wood matches well (note that even two trees growing next to each other will not have recognized that ring pattern matches are not unique.

A tree's growth rate changes in a predictable pattern throughout the year in response to seasonal climate changes, resulting in visible growth rings.

So the carbon ‘date’ is used to constrain just which match is acceptable.

Consequently, the calibration is a circular process and the tree ring chronology extension is also a circular process that is dependent on assumptions about the carbon dating system.

) of the White Mountains of Eastern California, were dated in 1957 by counting tree rings at 4,723 years old.

This would mean they pre-dated the Flood which occurred around 4,350 years ago, taking a straightforward approach to Biblical chronology.

Recent research on seasonal effects on tree rings in other trees in the same genus, the plantation pine , has revealed that up to five rings per year can be produced and extra rings are often indistinguishable, even under the microscope, from annual rings.
