) 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.

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).And so the tree-ring sequence is extended from the living trees backwards. Conventional carbon-14 dating assumes that the system has been in equilibrium for tens or hundreds of thousands of years, and that , chapter 4).The biggest problem with the process is that ring patterns are not unique.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.
