Dating oak tree
The gap between living and dead wood was first breached by A. Douglas while testing prehistoric beams in ruins near Show Low, Arizona. Experiments show the trees can grow more than one ring in unusual seasons.
Of course, "modern" evolutionists have held these dates up for ridicule, but the Bristlecone pine research may well verify them. Some experiments have even suggested that many periods of time could have been characterized by the growth of one extra ring every one to four years, with evidence in controlled laboratory situations showing extra ring growth tied to short drought periods.
Measuring the intensity of the luminescence can determine how much time has passed since the last time the object was heated.They lie in the rain shadow of the Sierras, with an average annual rainfall of 10-13 inches.Bristlecones grow in other similar areas and were already the focus of much speculation when Schulman arrived on the scene in 1953.His dendrochronological studies spanned almost thirty years, of which the last five were spent mostly in the White Mountains.Through the study of annual growth rings of these trees, a fairly precise method of absolute dating has been obtained.
