Sheltered slopes on the N end of the compass had a mixture of surface hoar and recrystalized faceted snow on the surface, slopes on the S end of the compass had either a melt freeze crust or damp snow depending on the time of day.

Comments

Yet another clear cold night has helped with the development of surface hoar and facets on the surface of slopes on the N end of the compass, sluffs are running noticeably farther than just a few days ago, and the trail breaking is getting slippery. We were getting long running sluffs in steep N facing terrain but they were easily manageable with ski cuts, they are definitely running fast enough and entraining enough snow for them to take you for a ride in steep, confined, and unforgiving terrain, seems the best technique is to ski cut, let them run then ski the line. It was definitely warm enough for wet activity but most of the S facing seems to have already run or baked out enough to stabilize. There is also still some massive cornices that I wouldn't trust getting out too far on with the warm temperatures. I'm thinking the important thing is to keep an eye on the surface and figure out what might get buried by the next wave of storms.

Photos: Ski cut produces large and fast running sluff, then the line is skied, natural sluffs in steep terrain, surface hoar growth, and the surface hoar feathers are getting so big you can grab a handful off the surface, suspect cornice
