Figure 4. Comparison of individual tree-ring time series of (A) standing dead trees and (B) fallen dead trees which are successfully cross-dated with the master chronology. The youngest tree rings in each tree, which have only earlywood (EW), were not measured (⇣: the year of the earliest dead tree ↓: the year of the latest dead tree).
