Tree-Ring Bulletin, Volume 28 (1967)
ABOUT THE COLLECTION
Tree-Ring Research is the peer-reviewed journal of the Tree Ring Society. The journal was first published in 1934 under the title Tree-Ring Bulletin. In 2001, the title changed to Tree-Ring Research.
Issues from 1934–2006 are freely available on the publications section of the Tree-Ring Society website. The Tree-Ring Society and the Laboratory of Tree-Ring Research at the University of Arizona partnered with the University Libraries to re-digitize back issues for improved searching capabilities and long-term preservation.

Archaeological Tree-Ring Dates from Wetherill Mesa(Tree-Ring Society, 1967-05)The 1,916 wood and charcoal specimens obtained from five years of survey and excavations on Wetherill Mesa produced 501 tree-ring dates. The dated specimens filled a gap between A.D. 674 and 733, greatly lengthening the combined species' tree-ring series for Mesa Verde so that it now extends from A.D. 161 to 1280. In addition a very long tree-ring series was established for juniper, a tree rarely dated from Mesa Verde in the past.
A Tree-Ring Chronology for Climatic Analysis(Tree-Ring Society, 1967-05)A long Douglas-fir tree-ring chronology was needed for use in a climatic interpretation of Mesa Verde. The archaeological portion of the chronology was derived from 21 archaeological specimens obtained from excavations on Wetherill Mesa and extended from A.D. 435 to 1276. The modern portion, extending to 1963, was derived from directional and non-directional cores from six very old living Douglas-fir trees. In addition, four directional cores from each of the six trees were used to compute tree-ring indices for the years 1860 to 1963, which have been used for an analysis of paleoclimate.
Introduction(Tree-Ring Society, 1967-05)The Wetherill Mesa Archeological Project devoted a portion of its funds and personnel to an attempt to reconstruct the past climate at Mesa Verde National Park. Data for this study were obtained from the thorough tree-ring dating of the archaeological excavations, from environmental measurement stations, and from measurements of tree growth. The results of the dendrochronological study on Wetherill Mesa include very long tree-ring chronologies; large clusters of dates from each site excavated on Wetherill Mesa; and a tentative climate reconstruction for Mesa Verde.
