 Comments: As I toured up once I hit an open SW ridge line around 8,100 feet the wind had formed a thin wind slab and sculptured the snow after the last storm on Tuesday/Wednesday. Around 8,300 ft the wind slab had gotten stiffer and thick about 3 cm. Dug a quick hand pit at 8,400ft HS 60 cm on a W aspect. 1mm facets at base to 5cm then a thick ice crust 3cm. T-day snow then another crust most likely from the days of sun and no snow between storms and then new snow from earlier this week.
On top went to NE aspect at 8700ft.once I rolled on to it the slope around me collapsed and settled a pretty big area around whumpfed. And I decided to get back on top of the ridge line. It was to foggy up top to see the surrounding terrain for new slides or anything off the NE side.
