This study demonstrates the potential of Pinus flexilis James (Limber pine) in southwestern Alberta to provide long dendroclimatic records of precipitation. The AA. present a 487-yr reconstruction of annual precipitation based on tree-ring widths
from living and subfossil Pinus flexilis obtained from three sample sites. They compare this record with the results of previous tree-ring studies to examine the degree of synchrony between droughts in southern Alberta and other portions of the North
