Old avalanche
Went to check out 1/29 human triggered avy at 2700′ on south face of marmot.
Old avalanche
No red flags contributing to instability
Variable- little bit of everything
HS 100-110cm. Conducted 6 person bonzai next to 1/29 avy. Got block to fail.
Also did ECTP 11-17 SC. Found pencil/1 finger wind slab over fist hard depth hoar.
Conclusion- poor structure and still exists 7 days after avy.
