Rain on wet snow on Andesite Ridge.

Steady moderate rain observed on Andesite Ridge. Rain on snow event following a couple of days of poor overnight snow surface refreeze. Deep wet snow conditions, marginally ski supportable. Deep boot penetration over the knee. Human triggered roller balls grew in size up to around a foot in diameter on NE-E aspects observed. Minor loose wet instability, still fairly difficult to skier trigger this morning.
