Description
Established in 1937, this University of Arizona facility is the world’s premier and largest center devoted to dendrochronology. This is the science of using trees and their annual growth rings to examine events and processes, both cultural and natural, with absolute time. Today the Laboratory contributes to many powerful insights into the long-term dynamics and history of the Earth and human societies. The research provides: climate history from tree rings; forest fire history from tree rings; history of environmental pollution recorded in tree rings as well as cultural history and information about geologic events. This tour will last 60 to 90 minutes.
