Snow Characteristics Comments

Down low in wind protected terrain the snow was inverted with 4 inched of dense snow sitting on lighter density snow, up higher in the exposed terrain dense wind slab was the special of the day, ski penetration was about 5 inches, did not really sink in far enough to hit the light density snow underneath.

Comments

Wanted to go check out South Monitor to see if the wind loading expected today was going to tip the scales in one of the only big bowls on the PC Ridgeline not to avalanche during the last cycle. The wind was not transporting snow to the level I thought it would, reasons for this would be the dense heavy snow on the winded south facing, and a lack of high wind speeds on the ridge line. That being said, cornices were growing larger and breaking off naturally and sympathetically if you walked to close to the edge. Still experienced some cracking and collapsing but nothing like earlier this week. The collapses seemed to be the dense 4 inch wind slab collapsing on the lighter density snow underneath and not going into the loose facets at the bottom. Did get one crack on a N facing roll just off the ridge in Mcdonalds to crack into the old faceted snow. South Monitor was quite drifted in the main bowl and I think this is the reason things are getting more stubborn. You might call this a highly suspect and untrustworthy bridge, probably not going to avalanche naturally, but with a trigger such as a skier there's still a good chance of a large and dangerous slide, think I'll wait and let things play out. Photos, crack into the old facets in Mcdonalds, cornices sympathetically released in West Monitor while walking too close to the edge, wind drifted S Monitor, old crowns from control work in Mcdonalds filling in.

Considerable for upper elevation E through N through W, Moderate in other terrain, a good thing to remember: its not all safe cause the sun is shinning
