Snowpit Observations
More detailed information about the snowpack: 

Toured up Tinemaha Creek drainage bt Birch and Tinemaha. Lots of wet slides from last week in the chutes on both peaks, Wind came up early 10am and just kept getting worse. Snow transport all the way down the mid elevation and lower steps. Wind affected snow and slabs across the canyons. Lots of quick hand pits, as it was too cold and windy for real pit. Consistent 10-20 cm windslab with fist/4F density snow underneath and then another slab. Slabs were 1finger to bullet proof. Sheers were easy to moderate on the top slab, 1-2m cracking around S facing rocks or edges of gulleys and hollow sounding. No slabs were visible having slid, but snow tornados and transport in the whole drainage. Transported snow was round pellets. Lower moraine outside of the mouth of canyon skied great - 2" deep corn on east/south facing aspects. Ski crampons were a necessity.
