The line is the average temperature and the bars are average precipitation at Lamoille Yost, 11 miles from the center point at 5,840 feet, station USC00264394 in the NOAA monthly climate normals for 1991 to 2020. Precipitation totals about 13 inches a year. The station sits about 4,000 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.
