Data for: High-elevation mountain hemlock growth as a surrogate for cool-season precipitation in Crater Lake National Park, USA

Measurements of tree-ring widths from seven mountain hemlock (Tsuga mertensiana [Bong.] Carr.) sites in Crater Lake National Park, Oregon. Ring-width data are stored as text files in Tucson decadal format (http://www.cybis.se/wiki/index.php?title=Tucson_format). Measurements are total ring-widths in microns. The first three lines of each file contain metadata describing:
*Three-letter site code
Site name
Tree species code
Country
Elevation (meters above sea level)
Latitude and longitude (decimal degrees)
First year of chronology
Final year
