Dendochronology

Dendochronology is tree-ring dating. Dendochronology is useful in climatology and to date paintings and buildings. For this lab, we had to look at two trees, one that grew in Georgia, which was 50-55 years old, and another from Palm Springs, California, that was 30-35 years old. Through comparing the data from each at 5 year intervals, I found that there was almost no correlation between average summer temperatures and tree ring thickness.

Addtionally, I put dates on the trees to show significant events in history.
