FATMAP difficulty grade
The western face of Kosciuszko holds the steepest gradient other than skiing directly below the corniced area, however the western aspect is exposed to the prevailing wind which can have some remarkable effects on the snow cover.
As you drop down, the face is open and one can choose from a variety of lines, just be careful of the granite outcrops, after snowfalls in midwinter, some can be hard to pick out, and in early season can take a chunk out of your bases.
Other than the exposure to the worst of the weather, the area holds some nice skiing and corns up nicely in the afternoon, leading to some rewarding skiing or boarding.
The best return from your run is to hike up either the north or south ridge line back to the summit of Kosciuszko.
