Avalanche slid at 11am this morning after overnight snowfall and drifting. The bedsurface was a thin melt-freeze crust (from the recent meltdown probably) with the failure layer being soft overlying broken (windblown) crystals. Note the surface roller ball activity to the right of the crownwall & running out further than the avalanche debris. Freezing level rose to around 750m and initiated this surface activity as well as the partial cornice collapse. The cornice line is still quite big though doesn’t show up well in the photo above…
Drifting all day at higher altitudes. See above and below. The weather was overcast for almost the entire day with just the occasional cloudbreak. Got very lucky with the first photo!
