Red Flags Comments
Wind loading was the main red flag today, large amounts of snow was being trasported onto the NE-E leeward slopes, in upper Cardiff.
Comments

Todays route was up Pole Line Pass from the Alta guard, dropping into Cardiff on the NW facing aspect off the pass, skiing that out down to the mine then up to Ivory Flakes E-NE facing. NW aspects had received allot of wind damage and were some what slabby and hollow, not too psyched on how the snow felt on that aspect. Wind damage reached all the way down to the mine on the NW aspects. Also like I said before the wind did a good job hammering all the upper elevation terrain in Cardiff, (Cardiac Ridge, Cardiac Bowl, LSB) it was also starting to hammer mid elevations in the drainage by the time we left. Noted couple day old avalanches, one was a new snow only slide that pulled out under the cliffs under N facing Cardiff Peak, the other slide was on Cardiac Ridge this slide went into old snow, it was on the E-SE facing part were the skin trail is usually put in, I'm thinking it ran on facets that had formed under a heat crust before last weeks storms.

Still might stick to considerable in high elevation wind loaded terrain, moderate in most other terrain
