Large natural sluffs in Flanders/Hyalite

From notes: "There was about 6" of new snow in Flanders. It snowed on and off all morning and kicked in again around noon. There was no wind. We climbed Killer Pillar (E. facing, ~8600'). In about a 45 minute span we had 5-6 large sluffs barrel over the top of the climb and run a few hundred feet down the gully...a long ways... It was running so fast and far I had to stop and dig a quick pit to see why. It was near-surface faceting under the snow... LS-N-R2-D,... by the time they all ran I imagine a lot of the bowl above had released. I was super psyched that we both had our lighweight shovels and probes and were beeping. You just never know!"
