Avalanche Forecast
Avalanche Bulletin - Little Yoho
Our information is limited but watch for isolated pockets of wind slab in the alpine. Skiing is possible above 2100m due to a buried crust down 10-15 cm that helps carry the weight of skiers, but hitting rocks or stumps is still a real concern.

Travel and Terrain Advice
- Be careful with wind loaded pockets while approaching and climbing ice routes.
Avalanche Summary
No recent avalanche activity has been observed or reported. Some small wind triggered sluffs were observed in steep gullies on Sunday with the potential to run quite far due to the presence of the Halloween crust.
Snowpack Summary
An average of 30-50 cm of snow at treeline with up to 100 cm in alpine locations. A crust formed prior to Halloween is down 10-15 cm helping provide support for skiers. This crust disappears on N aspects around 2500m. Alpine winds have created isolated pockets of wind slab. On glaciers be wary of the ice-snow interface and check it for instability.
Weather Forecast
A Northern flow continues to keep cold arctic air in our region for the next few days. Expect high overcast and light flurries with clearing skies mid-week. No significant snow accumulations are expected through the middle of the week.

This is a typical early winter avalanche problem that exists in isolated pockets where the snow has drifted into small wind slabs and the slope is steep enough to slide. Mainly a concern for ice climbers in steep gullies or walking above cliffs.
