Problem #1 Comments
For the past several days, winds have been gusting out of the West loading N-S slopes. This is especially evident on ridges and couloirs where terrain traps the transported snow and forms cornices and wind slabs.

We decided to assess wind loading on Maybird Couloir as we ascended. Due to the past avy cycle with last week's storms, we were expecting a safer experience with faceted layers being flushed out. We also expected to encounter refrozen wet loose debris due to the recent solar warming. Finally, we expected the skiing to be rough with a bit of zipper crust where there was no debris.
We ascended the chute and discussed conditions at 4 different points on the ascent. We noted no stability concerns until approx 9400' where wind effect was increasingly evident. We spaced out on our booter and noted that the pockets of wind impact were small and not reactive. Higher up upon the convergence with the ridgelines from Lisa's and Tanners, the wind slabs were larger and more cohesive. We did not get any reactivity upon ski cuts on decent and avoided growing cornices on the ridge. I dug a quick and dirty hand pit finding poor snowpack structure with the upper layer indicative of generally bad skiing.
Weather: the day began clear and cold with minimal wind. Clouds built during our 3 hour ascent and light to moderate snowfall accompanied the descent.
