Huemul Circuit

EXTREME // LETHAL
Full Route Report

Considered a premier multi-day trekking route in Los Glaciares National Park, the Huemul Circuit provides a circumnavigation of Cerro Huemul near El Chaltén. The route crosses two significant passes—Paso del Viento and Paso Huemul—offering direct panoramas of the Southern Patagonian Ice Field. Terrain varies from forested valley floors and river crossings to exposed glacial moraines and high-altitude scree slopes. The circuit is defined by its remoteness and the requirement for technical river crossing skills using fixed steel cables.

Sky Rim Trail

EXTREME // LETHAL
Full Route Report

The Sky Rim Trail is Yellowstone National Park's premier alpine ridge traverse, providing an experience completely unlike the park's famous geyser basins or crowded roadside viewing areas. Located on the remote northwestern boundary defining the border between Yellowstone (Wyoming) and the Gallatin National Forest (Montana), this grueling 21-mile loop acts as a 'roof' over the park. Hikers ascend steeply from the valley floor to a continuous, undulating ridgeline that remains above 9,000 feet for over 7 miles. The trail precariously hugs drop-offs, crosses massive grassy saddles, and summits several distinct peaks (including Big Horn Peak), offering unparalleled 360-degree, 100-mile views of the Absarokas, the Tetons to the south, and the Madison and Gallatin ranges in Montana.

HikeMetrics Hazard Scale — Explanation

STANDARD // RT

MODERATE // CHLG

EXPERT // HAZARD
5
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.

Full Scale Documentation
Route A // Hazard Verdict
Huemul Circuit
EXTREME // LETHAL
extreme_winds: Winds on the high passes can be severe, particularly in summer afternoons. Gusts may make progress slow and unstable.
river_tyrolean_traverse: Two river crossings require the use of fixed steel cables (tyrolean traverses) and specialized gear.
Route B // Hazard Verdict
Sky Rim Trail
EXTREME // LETHAL
grizzly bears: The Gallatin Range is dense grizzly habitat. Bears frequently traverse the high saddles looking for army cutworm moths in the talus slopes.
lightning and exposure: The 7-mile ridge is fully exposed above the tree line. If a thunderstorm rolls in, you are the highest point holding a metal trekking pole, and there is no fast route down to safety.
