Comments: 

'Tis the season for extended column tests.  About 90 seconds of digging gave me a full depth (HS 38cm!) pit, and I only wasted 9 wrist taps (on a second test, 3) to get full propagation and a collapse in the 2mm facets on the ground.  The facets here were smaller and damper than at higher elevations and on more northerly aspects.

 

 

Test-slope avalanche demonstrates what the collapsing and propagation were all about. 8,100' WNW.
