Both chronologies correlate most strongly with July temperature. The relationship with July temperature is inverse for the low-elevation Douglas-firs, due to moisture stress associated with high July temperatures, and positive for the high elevation whitebark pine, due to enhanced growing conditions at the cold treeline site. The tree-ring data are available in the International Tree Ring Data Bank at the NOAA/WDC Paleo website: http://www.ncdc.noaa.gov/paleo/treering.html Salmon River Valley Douglas-fir site id is ID014. Railroad Ridge whitebark pine site id is ID012. Railroad Ridge: 44.13N, 114.55W, 2930m elevation.

These cold intervals are interrupted by prolonged warm spells in the early 1400s, late 1500s, and in the 1930s. The spatial signature of the paleoclimatic record is centered on the north-central Rockies and Central Great Plains, and expands over North America following a wave-like pattern. Neither instrumental nor proxy data in Idaho northeast valleys show unusual warming during the twentieth century. Climate episodes over the last three centuries are in broad agreement with the Greenland borehole temperature history. Low-frequency patterns are consistent with other northern hemisphere tree-ring records for the late Holocene, and provide a chronology of warm and cold intervals during the Little Ice Age.
