Buttermilk

2,010 feet of lift-served vertical, from a base of 7,876 ft to a summit of 9,886 ft. Measured from the lowest and highest lift terminal on this mountain — not a box around a map pin — and cut into 5 five-hundred-foot bands.

Slope and aspect are the Horn 3×3 method on a ~13 m DEM. A band's aspect is the direction of the mean unit vector, not the mean of the angles. NDJFM mm is the PRISM 1991–2020 November–March precipitation normal at that height — liquid equivalent, not snow depth.

How this mountain gets scored

the verification station
Chapman Tunnel SNOTEL (1101:CO:SNTL) is 21.7 km away at 10,090 ft — -204 ft below this summit. It reports hourly precipitation, snow water equivalent and temperature at a surveyed elevation, which is the only truth at height that does not have to be interpolated first. Forecasts for this mountain will be scored there, and the score published whether or not it flatters.
