Snowpit Observations
More detailed information about the snowpack: 

We skinned up the drainage north of Wahoo/Kindergarten towards Mt Humphreys impressive SE face. Turned right and booted up an attractive couloir that was very close to due south facing. At ~1100 began booting up slightly moist, unconsolidated snow over a firm base. Boot pen averaged around 30cm. At 200 vertical feet below the top the snow abruptly changed to smooth, apparently recent, and moist snow over a firm base. The new snow depth averaged 10cm. We felt quite warm booting up the couloir.

We reached the top (12,350') at noon. Dropped in at 1220. The new moist snow wanted to slough on the firm surface, but would not run. No pinwheels formed. There did not appear to be any significant cohesion in the new snow. Skiing was poor to fair in the couloir. Fair to good on more consolidated snow on the apron. Smorgasbord on the exit - which was fast.
