How this score was built ⓘ
- Refreeze (× 0.5) 🏔️ 23% route froze +7.5
- Warming (× 0.3) +16.3
- Streak bonus (capped at 20) +0
- Final score 23.8 / 100
Why this score?
- Refreeze 15/100 contributed +8 pts (50% weight) — Heliotrope above freezing but 23% of route surface froze (0% from air temp + radiative cooling pulls surface freezing line lower) (freezing level ~9,640 ft). Snow surface estimated ~47°F (air 50°F − 2°F radiative cooling — sky 59% cloud, wind ×0.59, humidity ×0.78).
- Warming 54/100 contributed +16 pts (30% weight).
- Freeze/thaw streak is 0 days — base score (refreeze + warming) caps at 80 until a streak builds.
- 🏔️ Heliotrope above freezing — score boosted by route-frozen fraction (23% of route froze after radiative cooling)
