Avalanche Forecast
Avalanche Bulletin - Little Yoho
The main concerns right now are small buried wind slabs and sluffing in steep terrain. We have removed the persistent slab problem because of a lack of activity on this layer, but the structural weakness remains especially in shallow snowpack areas.

What Elevation?
Which Slopes?
Chances of Avalanches?
Expected Size?
Travel and Terrain Advice
- Watch for whumpfing, hollow sounds, and shooting cracks.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
Avalanche Summary
No new avalanche activity reported or observed in the Little Yoho region. We have not seen any avalanche activity on the persistent layers for about ten days and have removed this as a problem but in some places this structural weakness remains.
Snowpack Summary
Buried wind slabs exist in most open areas at higher elevations, with loose surface facets at lower elevations. Mid pack surface hoar is rounding and inactive in tests. Deep facet layers are weak but are presently difficult to propagate.
Weather Forecast
A few more cm's of new snow with light NE winds. Moderately cool temperatures are forecast. Bring spring please.

Wind slabs exist in lee areas in the alpine. While they may not be very thick or particularly touchy, they certainly have the potential to carry you into an undesirable location (cliffs/terrain traps) if triggered in steep terrain.
