How this score was built ⓘ
- Refreeze (× 0.5) 🏔️ 82% route froze +26.6
- Warming (× 0.3) +27.0
- Streak bonus (capped at 20) +20
- Final score 73.6 / 100
Why this score?
- Refreeze 53/100 contributed +27 pts (50% weight) — Timberline above freezing but 82% of route surface froze (75% from air temp + radiative cooling pulls surface freezing line lower) (freezing level ~6,652 ft). Snow surface estimated ~33°F (air 34°F − 1°F radiative cooling — sky 49% cloud, wind ×0.62, humidity ×0.38).
- Warming 90/100 contributed +27 pts (30% weight).
- Streak bonus capped at +20 pts (7 consecutive freeze days).
- 🏔️ Timberline above freezing — score boosted by route-frozen fraction (82% of route froze after radiative cooling)

Sanity-check this
- 🤔 Timberline didn't freeze (34°F) but ~75% of the route above did — corn quality improves with elevation. The lowest slopes near the trailhead may be icy or slushy instead of corn.
- 🤔 Daytime high (55°F) is on the warm edge of the corn window — south-facing aspects may go to mush before north-facing ones soften.
- 🤔 Wind (24 mph) is approaching the 25 mph penalty threshold — slight forecast revisions could flip the score.
