Sampling Thousand-Year-Old Wood

Caption: Christopher Baisan of the University of Arizona's Laboratory of Tree-Ring Research examines a cross-section of wood he's just removed from a dead Douglas-fir (Pseudotsuga menziesii) in a canyon near Price, Utah. Analysis later showed that the tree had started life around A.D. 960, lived through the epic drought of the 1100s and died in about 1421.
