How this score was built ⓘ
- Refreeze (× 0.5) 🏔️ 50% route froze +16.1
- Warming (× 0.3) +12.0
- Streak bonus (capped at 20) +0
- Final score 28.1 / 100
Why this score?
- Refreeze 32/100 contributed +16 pts (50% weight) — Climbers Bivouac above freezing but 50% of route surface froze (0% from air temp + radiative cooling pulls surface freezing line lower) (freezing level ~8,606 ft). Snow surface estimated ~46°F (air 49°F − 3°F radiative cooling — sky 48% cloud, wind ×0.69, humidity ×0.69).
- Warming 40/100 contributed +12 pts (30% weight).
- Freeze/thaw streak is 0 days — base score (refreeze + warming) caps at 80 until a streak builds.
- 🏔️ Climbers Bivouac above freezing — score boosted by route-frozen fraction (50% of route froze after radiative cooling)
