At 60 to 100 cm deep, it can be most likely triggered on steep roll-overs in wind-sheltered terrain around treeline.
There is a persistent weak layer in the snow pack.
Seek out smaller terrain with no overhead hazard to enjoy the good riding conditions at higher elevations.

25 cm of recent snow has fallen over a crust that is present up to 1400 m.
In sheltered areas, a layer of weak, feathery surface hoar crystals is buried about 75 cm deep.
At 1100 m and below a prominent crust is just below a skiff of fresh snow and makes for challenging travel.
The snowpack is around 150 cm deep at treeline, tapering quickly with elevation.
