The basis for stratigraphy seems quite intuitive today, but its applications were no less than earth-shattering to archaeological theory.Each tree then, contains a record of rainfall for the length of its life, expressed in density, trace element content, stable isotope composition, and intra-annual growth ring width.Using local pine trees, Douglass built a 450 year record of the tree ring variability.His research culminated in proving that tree ring width varies with annual rainfall.Not only that, it varies regionally, such that all trees within a specific species and region will show the same relative growth during wet years and dry years.
