Signs of Unstable Snow

Observations

We skied the Snot and Slot Couloirs on Mt. Snoqualmie today. On the Phantom slide, we found a firm sun crust that took until 2-3 pm for those slopes to soften with intermittent but occasionally intense solar input and was quite firm in the morning. The most recently fallen snow continues to improve its bond to the underlying snow. At higher elevations and more northerly aspects, that most recent storm snow overlays a firm crust (4/11?). At lower elevations and on southerly aspects, that interface still sits on very moist snow that is showing some signs of draining but is still very moist, to say the least. We did not observe any recently wind-transported snow.
