Weather Comments
Things really warmed up today, even more than yesterday, but sun angle is still cutting us a little slack even though it is March, we stuck to N facing area 10,000' interspersed with large firs, way warm in the sun, rollers observed on south facing slopes across canyon from us, breakable crust in flats had softened to turnable late afternoon on exit.

Snow Characteristics Comments

still able to find excellent settled snow on N facing sheltered slopes, faceting apparent, and some areas of large surface hoar although not widespread, did make for some loud powder turns today.  Heat is getting to sun exposed flats, W/S/E slopes and forming crusts.  We continue to enjoy a stable snowpack, and concerns shift to faceted snow on surface, ahead of next storm when it comes

Red Flags Comments
we did find evidence of activity both prior to last storm, with cornice drops initiating wind slabs, some covered by the last lower density snow, and in some extreme steep rocky terrain with shallow snowpack, activity noted in last storm

Problem #1 Comments

Cornices in places we have never seen them before, some very big, and while starting to get old now, still not to be trusted 

Avalanche Problem #2

Loose Wet Snow
Trend
Same
Problem #2 Comments

heating on new snow did promote some rollers and even small wet slides south facing steep slopes, with continued heating, would expect that to continue, but easily managed by getting off or from underneath before max heating for the day.
