Amicalola, Georgia - ga010 Additional Site Information N. Pederson B. Catron K. Tackett Notes: Some raw data here have values of -8888 for years where the rings were distorted or otherwise not useful for dendroclimatology. The latest version of ARSTAN reads these as dummy variables and can in-fill these gaps. Amicalola LITU were lumped with the collection from Frick Creek, GA to make the Chattahoochee National Forest LITU chronology used in the final reconstruction. So, only raw ring width data are uploaded for this site. A site chronology was not created for this collection. Reference: Pederson, N., A.R. Bell, T.A. Knight, C. Leland, N. Malcomb, K.J.
