Beautiful day up on Jughandle with clear views in all directions and spring-like temps.  

We made managing the low tide conditions our primary focus and stuck to low angle terrain throughout the day. 

Protected terrain is capped with settled, recrystallized powder while terrain with any wind exposure varies from supportable to breakable wind board and scalloped surfaces.  We experienced consistent localized collapsing (dinner-plating) and a couple of larger collapses (audible) while ascending the west side of Jughandle at around 7K.  

We dug a quick pit on a protected NE aspect at 7650'.  The poor snowpack structure was immediately evident when you stepped out of your skis and sunk to your waist.  HS: 96cm, CT14 SC & ECTN14 on an obvious layer of 4mm surface hoar 30cm down.  CT18 SC 23cm from the ground in 2mm basal facets.  None of these failures were very “energetic”.  It seems like the snowpack has adjusted to the last couple loading events in this protected location.  I’d be suspect of the same structure in wind-loaded terrain.

More detailed information about the weather: 

Moderate SE winds with strong gusts were observed along the summit ridge.  There was some minimal wind transport taking place however not much loose snow available for transport remaining in exposed terrain.  

The snow surface below 6K was damp during our exit around 1500.
