Regions

Glacier.

Varying degrees of wind affect in the alpine down into tree line, with areas of soft snow. Lower elevation skiing is crusty.

Its like spring skiing... minus the warmth and corn snow.

Weather Forecast

Saturday will see a mix of sun and cloud, 10-20km/hr Easterly winds, a freezing level rising to 1500m and an alpine temperature high of -6. Similar weather pattern for the next few days until Tuesday, where we might see another small winter storm system roll through with 10cm of snow.

Snowpack Summary

A supportive crust from valley bottom to ~2200m makes for quick travel (ski crampons recommended). Preserved soft snow can typically be found on Northerly slopes at higher elevations. Wind affected snow in the alpine from the Northerly winds these past few days with some pockets of wind slab.

Avalanche Summary

A size 2.0 slab pulled out of Lone Pine on Friday, running to the top of the fan.

On Wednesday, there was a size 3 cornice fall off of Mt Bonney (triggered by a skier on belay). And on Monday, there was a close call when a small wind slab nearly took a skier into a crevasse!

Confidence

Problems

Cornices

Cornice Fall is the release of an overhanging mass of snow that forms as the wind moves snow over a sharp terrain feature, such as a ridge, and deposits snow on the downwind (leeward) side. Cornices range in size from small wind drifts of soft snow to large overhangs of hard snow that are 30 feet (10 meters) or taller. They can break off the terrain suddenly and pull back onto the ridge top and catch people by surprise even on the flat ground above the slope. Even small cornices can have enough mass to be destructive and deadly. Cornice Fall can entrain loose surface snow or trigger slab avalanches.
