There have been isolated, skier reactive slab avalanches to size 1.5 reported on weak, feathery surface hoar crystals buried 25-50cm at treeline and in the lower alpine. 

A professional operation reported a slab avalanche being triggered by a wet loose avalanche from above on Thursday. 

There's a lot going on in the upper snowpack. Careful assessment is recommended. 

There is now a crust on the surface at lower elevations and on solar aspects at treeline.

Feathery, weak surface hoar crystals buried around February 26th are now found down 25-50cm most prominently at treeline elevations. There have been reports of this layer being reactive to skier traffic. 

A thick crust buried in mid-February is now found down 60-100cm. Though there has been little avalanche activity reported on this layer, it should be treated with suspicion. 

The lower snowpack is effectively bridged by the layers above and we do not expect avalanches to be triggered in the lower snowpack at this time. 

• Carefully assess open slopes and convex rolls where buried surface hoar may be preserved.
• Surface hoar distribution is highly variable. Avoid generalizing your observations.
• Avoid travelling on slopes below cornices.
• Firm cornices can pull back into flat terrain at ridgetop if they fail.
