[MCR] Mt Athabasca

 Took a run at Mt Athabasca today, we made it as high as the base of the Silverhorn in light to moderate snowfalls and deteriorating visibility. Moderate winds gusting to strong at times, were redistributing the snow into windslabs up to 35cm in places.  Snow depths  at 2700m were highly variable, but averaged 20cm.  Many crevasses were brushed over with weak bridges, attentive route finding and probing was necessary.

On our descent we saw fresh debris from a loose sz 1.5 avalanche starting off the silverhorn and running across the ramp.  

Another wave of precipitation and wind is forecast to push through again tonite and early tomorrow. It may take a couple of days for these snow instabilities to settle out.
