Comments
After checking and double checking and triple checking that there was no one below, I tapped on a big obvious cornice just east of the flagstaff skin track.
The cornice broke easily and intact. The upper part of the slope was steep and rocky and that snow immediately was scoured off. Low on the slope it triggered an adjacent snow field and picked up a descent amount of debris.
It was hard to see around corner but I'd guess the second slope was 20 or 30 feet away. My guess for the combined width was maybe 50'. My best guess was that the crown was 6 or 8". Also was soft.
Not a huge thing I guess but interesting.
