Archaeological Tree-Ring Dates from Wetherill Mesa Nichols, Robert F.; Harlan, Thomas P. 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. Contains: References, Indices for Four Directional Cores from SOT-1 to -6, Douglas-fir Indices for Climatic Analysis, Composite Species Indices for all Archaeological Specimens from Wetherill Mesa, Juniper Indices for Wetherill Mesa Archaeological Sites (A.D. 301-1274), Pinyon Pine Indices for Wetherill Mesa Archaeological Sites (A.D. 161-355; 486-1278), Douglas-fir Indices for Wetherill Mesa Archaeological Sites (A.D. 435-1276), Ponderosa Pine Indices for Wetherill Mesa Archaelogical Sites (A.D. 1060-1269)

A Tree-Ring Chronology for Climatic Analysis Smith, David G.; Nichols, Robert F. 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 Osbourne, Douglas; Nichols, Robert F. 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.
