Comments

Strong westerly ridgetop winds drifted recent storm snow to the leeward side of upper elevation terrain in the wind zone. Cornices were particularly tender, breaking further back than you might expect, and initiating slabs as they trundled steep terrain below.

This slide on a steep NE facing slope, broke into weak, old snow near a rock band close to the ridge.

Once triggered, yesterday's slabs were running a surprisingly long distance and could definitely ruin your day if you were on the receiving end.

This smaller natural slide quickly lost steam as it descended the slope.

 

 

Comments

A few drainages to the west in mid Weber Canyon we found much less wind effect and natural cornice failures produced no avalanches.

 

Comments

Lower parts of the canyon look more like mid March than early February.
