Went for a ski on Jumbo Mountain via the Lava lake parking lot....
The big surprises for the day were 3 separate deep slab avalanches since the most recent loading event (likely 4/3). Photos are attached. The first that we sighted was on the N/NE face of Jumbo. It appears to be cornice fall triggering a windslab that stepped down, photo attached.
HS-N-R2-D2-O @ around 10000ft on the N/NE face of Jumbo.
the next that we sighted was a large deep slab on the E face of the ridge just north of the true summit of Jumbo.
HS-N-R2-D2.5-O @ around 10,000ft.
The real show stopper was on the E face of Jumbo.
HS-N-R4-D3.5-O/G. Approximate crown width of 1000ft and average depth of 6-8ft. Total run of around 2000ft. A few photos attached.
other slides of note, a few D1-1.5 WL slides low in the basin SW facing. Also, an older deep slab on N facing terrain just south of Hell Roaring Lake, D2-D2.5.

Lots of naturals and maybe a rider triggered avalanche seen today. Steep solar aspects had lots of wet loose activity and small cornice/pillow fall.
