This page contains photos from the Laboratory of Tree-Ring Research in the University of Arizona’s College of Science.
The Laboratory of Tree-Ring Research is a global hub of dendrochronology: the science of dating events and changes in the environment by analyzing the annual growth patterns of rings inside of tree trunks. The lab uses such practices to study interactions of the earth’s climate, ecosystems and people throughout history. The lab was created in 1937 by A.E. Douglass, the founder of dendrochronology.
Tree-ring research at the University of Arizona and elsewhere has revealed historic flows in the Colorado River Basin dating back more than 1,200 years.
Information about tours of the Laboratory of Tree-Ring Research can be found here.
