| Recent Avalanches? | Yes |
| Collapsing (Whumphing)? | Yes |
| Cracking (Shooting cracks)? | Yes |
Observation: Hatcher Pass
Location: Independence mine area
Three groups traveled to Cross Hill, Independence Mine, and below Eldorado Bowl
Obvious signs of instability
Observer Comments
Whoomfing and large shooting cracks. Observed recent D2 in Eldorado Bowl (failed to ground), north aspect. Also observed recent D2 in Martin Mine Gully. Naturals on Fishhook creek. Widespread wind loading. Wind loaded test slopes very reactive, producing remote triggered avalanche on test slope below Eldorado Bowl.
Weather
Significant snow transport in morning, loading north aspects. Overcast, temps in low 20s.
Snow surface
Variable; soft new snow to pencil hard wind slabs.
Snowpack
Wind slabs on test slopes were reactive to human triggers.
In pits the windslabs generally failed at CT 1-7 (ECTP 8), at new/old snow interface. In CT/ECT's, basal facets generally failed at moderate forces with propagation.
