Avalanche Summary
Two large (size 2.5 and 3) wet slab avalanches were solar triggered either side of Grizzly couloir on Saturday failing on the April 9th crust.
Numerous loose wet avalanches were observed from sun exposed slopes late last week.
Snowpack Summary
In the Alpine and Tree-line, 20-30cm of heavy moist snow sits over a firm crust on any slope that faces the sun. Dry snow may be found on high north facing slopes
At tree line the snow depth is at a record low of around 220cm. The Feb 3rd crust/facet layer persists at upper elevations, buried down 80-140cm.
Below treeline the snowpack is going through its typical spring melt/freeze cycle, firm in the morning then breaking down and becoming isothermal with daily warming.
