I can tell you that the "snow" is fscking rubbish. it's all ice. from the top of twynam to the swing bridge across the snowy i skied on, perhaps, a total of 5m of snow. the remainder was varying thicknesses of ice. I reckon that blue lake would be amazing.
Basically, for the last week it's been around the +5 degree mark during the day and around the -5 during the night. It's the most amazing freeze/thaw cycle.
Ice - Excellent+++
Snow - rubbish++++
a lot of the snow no longer exists. hard to get a ski run even from guthega to the first bridge there's so little snow left. then from the top of the first ridge down to the flats in front of illawong hut there are quite a few bushy patches that you have to walk or scratch your skis on. Lots of shrubs exposed around spencers creek and on both sides of the snowy river below ~1700m (i say that because i reference the 1712m feature just across from illawong hut on the perisher map).
Post edit: wowsers about the rubbish ice conditions that gm84 just posted. figured that the freeze/thaw cycle would've helped it.
