A brief period of radiation from 1415- snow's surface remained dry but thickened up enough to add a bit of energy to the 29-30 Jan storm snow- failure plane mid storm F- 4F density change (no evidence of the 30 Jan Rime Crust at this aspect/ elevation). A turn on a steep SSE facing convexity produced a pushalanche that slowly oozed its way down slope. Dont see this interface as being capable of producing anything hazardous with the exception of long/ exposed paths. Didn't hang around long enough for any more than a quick hand pit but observed not much change with the old snow structure -a series of crust/ softer snow sandwiches with the weakest snow seemingly a 15-20cm layer of 2mm faceted grains underlying a 4-6cm thick 31 Dec melt/ freeze crust- this around 45cm down.
