Rattlesnake Mountain and Town Pound, Rumney, New Hampshire - nh005 Additional Site Information Peter Clark, Stockton Maxwell, and the 2009 NADEF Dendroclimb-atology group Purpose of Collection: Climatology Detrend Method: Smoothing spline fixed N cutoff Cores are stored at: Hampshire College, Amherst, MA Notes: Samples were collected between 2007 and 2009 for the 2009 North American Dendroecology Fieldweek's dendroclimb-atology group. These red pine grow on the schist cliff tops, faces, and talus fields found on Rattlesnake Mountain and the Town Pound in Rumney, NH. This site was selected to analyse the climate response of cliff side trees and to introduce cliff side sampling methods to group participants. Number of dated series 53 Master series 1690 2008 319 yrs Total rings in all series 8210 Total dated rings checked 8195 Series intercorrelation .549 Average mean sensitivity .274 Segments, possible problems 19 Mean length of series 154.9 A 150-year cubic smoothing spline was used. EPS drops around 1840. The residual chronology was used for climate analysis. Regression analysis of PDSI and precipitation data resulted in a reconstruction explaining 22.7 and 29.4 of the variance, respectively.
