Tree-Ring Analysis at Petrified Forest National Park, Arizona

Summary

Samples of ponderosa pine and juniper have been collected from various historic sites at the Petrified Forest National Park. Historic sites include several structures that were built by the Civilian Conservation Corps in the 1930s, old fences and sign posts, as well as Navajo hogans. The CCC structures were constructed with ponderosa pine beams that were imported to the park from sources not too far from the Petrified Forest. From tree-ring analysis, climatic variations in the past can be inferred from these CCC structures. Old fences, sign posts and Navajo hogan roof beam samples of juniper are also being analyzed. The presence of cut old growth juniper is apparent and will provide an interesting perspective on past structures in the Petrified Forest.
