Comment
Opening Day at Mt Waterman. . . boo-yah!
NE winds scoured N ridges, NE & E aspects, and left snow on NW aspects and N faces below ridges (i.e. 'The Face' was off the chain in the afternoon).
Other than wind, we observed no signs of instability. Our main concern was icy conditions as the 30 cm (1 ft) of well adhered blower pow had blown away revealing the rain crust. Bummer. But in treed areas, there were pockets of pow stashes where it was easy to turn; making for highly variable riding/skiing conditions.
 
* HS66 (all measurements are from the ground up)
* STM to ground on basal facets
* CTM20@22 Q3
* CTH21@22 Q3
* CTM17@52
* ECTN22@51
 
When I pulled down the columns after each test, they'd hit the ground and the upper ice layers would break like dropping a deck of playing cards— in perfectly smooth planes.
