South Columbia
Pericolo valanghe
In sintesi
Avalanche hazard is low, It's a good time to explore.
Use normal caution and good travel habits, keeping cornice hazard in mind as you move through terrain.
Confidence
High
- We are confident due to a stable weather pattern.
Avalanche Summary
Over the past week several natural cornice falls have been observed in the region. These cornices did not trigger avalanches on the slopes below.
Some natural glide slab releases have also been observed, these hazards should be given a wide berth.
Snowpack Summary
A crust, with surface hoar above it, extends up to at least 2000 m on all aspects and to mountain tops on solar aspects. On north aspects in the alpine, dry wind-affected snow may still be found.
Cornices are large and overhanging.
Weak layers from mid December and early January are still found in the upper and mid snowpack. Triggering these layers is unlikely, except with large loads or in thin snowpack areas.

Terrain and Travel Advice
- Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
- A hard crust on the snow surface will help strengthen the snowpack, but may cause tough travel conditions.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
- Be alert to conditions that change with elevation and sun exposure.
- Make observations and continually assess conditions as you travel.
