Abstract

The presence of false rings was documented for over 100 samples (increment cores and cross-sections) from the Border Lakes Region. Marker years were characterized as years in which three or more trees at a site exhibited a false ring. The two modern false ring events were cross-referenced with instrumental precipitation data, and the full chronology was overlain with the nearest North American Drought Atlas PDSI reconstruction. The largest contributing factor to widespread false ring formation in this area is likely moisture stress.
