Below 35°C

Cross an autumn mountain ridge in China's Qinling range, from Tangkou to Baxian Summit (3771 m). Rain, hail, wind and nightfall all pull your body temperature down. Manage layers, dry clothes, food, gas and your tent to stay above 35°C — or know when to turn back.

Body temperature is in Celsius: 37°C (98.6°F) is normal, below 35°C (95°F) is hypothermia.

Made for Mini Jam 221: Autumn (limitation: Staying Warm). English / 中文 — switch in the top-right corner. Sound is synthesized in real time with Web Audio; no audio files.

Inspired by the real Aotai traverse, where many hikers have died from hypothermia. The route is now officially closed.
