    Around 10 to 40 cm of snow sits above a weak layer of surface hoar and a crust on south aspects. The surface hoar is likely best preserved in shaded and sheltered areas between 1500 m and 1900 m.

Snowpack Summary

Around 10 cm of wind-affected snow overlies hard wind-consolidated snow in exposed terrain and a melt-freeze crust on southerly aspects. You may be able to find isolated pockets of wind slab in steep alpine terrain features. Beneath this, around 10 to 40 cm of snow overlies a weak layer of feathery surface hoar crystals on shady and sheltered slopes. This layer may be most prominent between 1500 m and 1900 m.The remainder of the snowpack is generally well-settled. Thin snowpack areas, such as in the east of the region, may find weak and sugary faceted grains near the base of the snowpack.
