No signs of instability observed. One recent avalanche that looks like the work of the Feb. PWL (see below).
In Convict Creek, wind more than snowfall seems to have been the dominant weather factor in the last storm. There is noticeably less snow between Morrison and McGee now than there was a week ago. Bare ground, sastrugi, fossil tracks and avalanche crowns have been unearthed by 100 mph wind over the past 48 hours. Travel was difficult in all but the most protected areas due to a mixture of old melt freeze crusts and sastrgui in low angle terrain. The exceptions are north faces which are fat and look to hold smooth if not soft snow.
Scattered snow showers and light to moderate wind along ridges in the afternoon. Cold.
|Past 48 hours
|Suspected release on the Feb. PWL during the March 4-5th loading event. This is the kind of terrain where activity has been observed during periods when avlanche activity on the layer was isolated - Steep N facing and protected from wind and sun by surrounding terrain.
At 9700′ on a sparsely treed W aspect with 30 degree slope I found HS~250cm and the Feb. PWL down 85cm. 4F+ 1.5mm FCxr in two 3cm layers separated by a 5cm faceted wind board. Slab above average hardness 1F. PWL did not show up in an ECT. PST 90/120 End.
