Snow Preservation Score

How well each resort's mapped terrain is oriented for holding onto snow, relative to a neutral baseline — the same location, same slope, averaged evenly across every compass direction. This isolates terrain orientation from latitude and elevation, which the resort's Rain Susceptibility Score already accounts for separately.

Score version: ASPECT_V3_FIXED_COORDS. Trail geometry via OpenSkiMap / OpenStreetMap contributors (ODbL).

Bearing is the vertical-drop-weighted mean fall-line direction of mapped runs (0° = north). Alignment (0–1) is how consistently oriented that terrain is. Aspect ratio below 1.00 means the resort's real orientation beats a directionless version of the same mountain at the same location; the bar's right edge marks that 1.00 neutral point.
