From email 2/18/22: "Went to Fairy Lake today. Booted up totally wind-bared grass to the top of love chutes, skied those. They were pretty much wind board, though there might have been a few places with some drifted snow that was slabby. Then we skinned up the basin to Frazier lake and saw lots of very reactive little wind slabs.... Throughout most of the terrain in Frazier around treeline there was wind slab everywhere."
