Put A Ring On It: Dating Trees, Volcanoes, and the Sun


7 to 8 p.m., Feb. 14, 2024


Dr. Charlotte Pearson
Associate Professor, Tree Ring Laboratory

When tree-ring scientists 'put a ring on it' they apply an exact calendar date to a band of tree growth. This band can be unpacked and used as a dated time-capsule through history where we can explore past events and make future predictions. Explore the inside of a tree with Dr. Pearson of the Laboratory of Tree-Ring Research and discover the surprising twists that emerged from the development of tree-ring science at the University of Arizona.
