Small wind slabs may be possible to trigger in extreme terrain.
A few small, wet loose avalanches were reported on Monday. As well as some large cornices failing naturally.
The upper snowpack consists of:
Thin sun-crusts on steep slopes facing the sun.
Large surface hoar growing in sheltered spots
Sugary facets near the surface from large day-night temperature swings.
A second crust is buried 60 to 100 cm deep and may have a layer of surface hoar sitting above it. Recent tests show this layer is improving.
The remainder of the mid and lower snowpack is well-settled.
Snow depths at treeline are roughly 100 to 150 cm.
