Take a tour of the first Laboratory in the world dedicated to dendrochronology or tree-ring science! The science of dendrochronology was developed here at the University of Arizona. Dendrochronology - or the study of tree-rings to understand the past climate - is more than just counting rings. Tree-rings can tell us about the world around us, now and in the past. Each tree tells a unique story about its experiences. We offer a variety of hands-on programs and tours for all ages, as well as classroom visits.
