One collapse with weight of 8 people in close proximity, at 1250 feet elevation, SW aspect, on Center Ridge.
No new, Calm
Center Ridge, SW aspect, 1250 feet, 29º slope.
Consistent failure on surface hoar 45cm down, CT12-14, Q1-2 (SP), ECTP14. From top, snow overlaying weak layer was, 15cm NSF (Fist hard), 15cm melt-freeze crust (Pencil+ hard), 15cm rounds (1 finger hard).
Similar findings in pits on sunburst at 1200 feet, W aspect. Similar findings in pits (slightly less reactive) on Tincan at 2200 feet, but rounds instead of melt-freeze layer overlaying the weak layer.
