Fairly warm but the clouds kept it from getting too hot, the few times the sun did poke out wet activity was noted on SE facing Cardiac Ridge. Not much wind at all.

Snow Characteristics Comments

Three inches of new over night, mostly consisting of graupel, the base was supportable unlike the inverted conditions I experienced yesterday, I guess creamy would be the word for it. Snow was damp 8700ft and below.

Comments

Went to Cardiac Ridge today to have a look at what happened during the storm, only avalanche activity noted in the upper drainage was a west facing slide just down canyon from Holy Toledo (DETAILS) that went to the ground most likely yesterday. The density inversion was much less pronounced today with settlement and warm temps. Luckily for us the sun only poked it's head out for a brief period, and the cloud cover kept things cool. Did note a large slide off Kessler east facing, put that on the avy page. (DETAILS)

Clouds keeping it cool most of the day.

Sun poking out for a brief period inducing some minor wet activity.

Supportable base with about 4 inches ski penetration.

Seems that things are stabilizing quickly, but would still be cautious of steeper previously thin and rocky areas. These are the type of slopes that seemed to have avalanched during the storm and after with explosive. From what I've gathered today there also seems to be a pattern of W, NW steep rocky slopes failing on old facets, ( slide next to Holy Toledo, North Baldy explosive triggered, Red Baldy). Thinking moderate in most other terrain.

FORECASTER COMMENTS: Mark met up with my partner and I mid day and I concur with Mark's assessment. We checked out one more area after Mark left and did experience a decent sized collapse while skinning. It was the density inversion from Friday that collapsed on a 35 degree slope. No cracking or avalanches resulted. There is no doubt that this instability is much less sensitive today than over the last couple.

Regarding the deep slab issue, after looking at the west facing slide near Holy Toledo, we thought we'd skip going into Mineral Fork through the Room of Doom which also has a west facing aspect that was nice and loaded - Kobernik
