EXTREME // LETHAL

The HikeMetrics Hazard Scale is a proprietary 5-point classification system that evaluates hiking routes across five dimensions: physical demand, technical complexity, altitude exposure, weather risk, and rescue accessibility.

Unlike generic star ratings, the Hazard Scale is calibrated against altitude profiles, elevation gain per day, and logistical isolation factors — making it the most precise route classification system available.

extreme winds: The wind coming off the Southern Patagonian Ice Field across Lago Grey can be forceful, sometimes blowing hikers off their feet.
cold exposure: Even in mid-summer, the ambient temperature near the glacier drops significantly.
