Avalanche Summary
On Thursday our field team observed several loose wet avalanches up to size 1.5 in the treeline and above. Ski cutting produced small wet slabs running on a crust down 15cm at 1100m.
Snowpack Summary
up to 15 cm of recent snow has formed wind slab in exposed alpine terrain. Below this a 1 cm thick crust can be found up to 1400 m.
Another crust from late January exists down 30 to 50 cm that extends up to mountain tops. This crust is over 10 cm thick.
Moist snow surfaces can be found at and below treeline from rain and warm temperatures.
The mid and lower snow pack is well settled but shallow at low elevations leaving many hazards just below the surface.
