Above 1800m there is going to be between 10-100cm of new snow depending on the elevation and more so on slopes lee to the West or Nor'west (the windward slopes may well be scoured to old ice), over a predominately wet grain snowpack.
There are layers underneath this of less consolidated decomposing fragments and loose wet grains sandwiched with Icy, firm layers.
