High Alpine: Above 2000m
Alpine: 1000 to 2000m
Low Alpine: Below 1000m
Description:
If a steep S or Se aspect ( or well shaded ) slope above 1900m has relatively thin snow cover you might want to check for the presence of weak sugary facetted snow buried beneath shallow windslab and how well it's stuck together.

Current Snowpack Conditions

Current Snowpack Conditions
Snow conditions are reportedly pretty well settled and stable around the ski area. Layers of weak sugary snow ( AKA facets) have been identified in the Two Thumb and Gammack ranges( often associated with buried rain crusts.) They are likely to exist in some spots in the ohau back country as well. The chance of triggering a slide on buried facets is low but it could still be worth having a look for them on steep shady slopes that do not show signs of prior avalanching.

Sliding Danger

Slide For Life
yes you could take a long sliding fall and whack into sharp rocks in a lot of places right now... especially in the morning ( or in the shade) when the snow is still frozen hard.
