Precipitation totals about 31 inches a year. The dotted line is average snowfall, about 118 inches a year on the same inches scale. The station sits about 2,100 feet lower than the center point, so temperatures on the ground run cooler.

Large units span more than one climate. The station stands in for the center point, and the outer parts of the boundary can be warmer or colder.
