Skied up the sisters today. Mostly ice but steep solar slope corned up a bit. The ice seems to have faceted out and is reasonably edgable in most places. The ramp is very scoured and icey and rocky. The approach couloir seems to be going through a melt freeze with morning sun and was soft on the way up and ice on the down. Super windy at the top! But not much snow to transport. The inversion didn't seem to be super strong as most slopes did not get moist. No pinwheeling or avalanches observed.
