With better overnight freezes and clearer nights, it might be time to start thinking about getting E & S facing aspects early in the day to start getting some corn snow. The full snowpack is far from a spring snowpack, but we are slowly heading that way.
Summary
Confidence
Avalanche Summary
No new avalanches observed or reported today
Thanks for this great MIN, quick, easy and paints the spring picture well.
Snowpack Summary
Crusts are found on all aspects below 2400m, and higher on solar aspects. Strong westerly winds yesterday and last night redistributed a lot of snow at upper elevations and wind slabs are found in alpine areas along ridgelines and in lee and cross-loaded features.
An important thing to consider at this time of year is the quality of the freeze overnight. Avalanche danger can change from low in the cool mornings to high in the hot afternoons. The timing of this change is important to monitor so plan you trips with these factors in mind.
Weather Summary
What will Wednesday bring?
A mix of sun and cloud and a predicted good overnight freeze. Day time high's of -6 will keep the snow from deterioting to much and Light winds out of the West.
Freezing levels to rise to 2100m.

Terrain and Travel Advice
- The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.
- Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
- Recent wind has varied in direction so watch for wind slabs on all aspects.
- Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
Problems
Wind Slabs
Recently formed wind slabs will be found on lee and cross-loaded terrain due to extreme west winds in the past 36hrs. Also watch for previously formed wind slabs on all aspects due to a period of northerly winds. These slabs will be more reactive where they are overlying a temperature crust.
Aspects: All aspects.
Elevations: Alpine.
Likelihood
Expected Size
Deep Persistent Slabs
Facets near the base of the snowpack may be triggered from thin areas and this season there are lots of thin areas. Dont try to outsmart the snowpack and stick to conservative terrain until we get into a good spring diurnal cycle.
Aspects: All aspects.
Elevations: All elevations.
Likelihood
Expected Size
Persistent Slabs
The Feb crust has been the main bed surface for many avalanches this winter. Slopes and features that have not slid should be treated cautiously or just avoided. Dig and look.
Aspects: North, North East, East, West, North West.
Elevations: Alpine, Treeline.
