Avalanche Summary
A Saturday report documented a large cornice falling naturally on a northwest aspect at 2200 m did not trigger the slope below, but the cornice itself ran quite far downslope.
Rapid warming triggered a loose wet avalanche cycle from solar slopes Last Thursday afternoon. The snowpack has since cooled and avalanche activity is unlikely, but re-frozen debris could be a real travel hazard.
Snowpack Summary
Wind has impacted 5-30 cm of recent snowfall. This covers a crust up to 2200 m and to mountain top on steep, solar slopes.
A thick rain crust with facets above from early December is buried around 100-200 cm deep. Large avalanches were naturally triggered on this layer during the last significant warming event in western terrain near the Bugaboos. With cold temperatures, avalanche activity on this layer is unlikely, however could easily wake up again with the next major input of moisture or heat.
Terrain and Travel
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Problems
Wind Slabs
Easterly winds Monday could build fresh slabs in less common areas. Check for reactive slabs around steep and high-consequence slopes.
