Chestnut Mountain Resort

414 feet of lift-served vertical, from a base of 600 ft to a summit of 1,014 ft. Measured from the lowest and highest lift terminal on this mountain — not a box around a map pin — and cut into 2 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
No SNOTEL within 25 km. SNOTEL is a western network, so this mountain is verified against the NOHRSC snowfall analysis and the nearest COOP and ASOS observations instead — all coarser, and none of them at summit height. That is a real limit on what can be claimed here, and it is stated rather than hidden.
