We skied a couple of laps on Zoa today after a pleasant tour up the ridge. We opted for lower-angle and supported terrain, abundant in this area. Some old tracks were visible on the steeper glades. We conducted a snowpack test near ridge-top, then chose to ski conservatively.

The reason for caution is the crust / storm-snow interface is the predominant weakness, it fails with a clean planer result. Testing today compared to testing on March 1st, revealed the possibility of slab propagation continues to be a concern. (Test results were slightly different today; Progressive Saw Test, PST 80/100 down 90cm, failing at the end of the column with a clean shear), This indicates to me that a deep persistent weakness persists and may linger for some time.

No recent activity was observed except some small slabs avalanches ran off the rock slabs on Yak. These slabs didn’t run far,

We had very good skiing on N, but the S became moist in PM. There was no wind, it was calm under a broken sky with some flurries, in the AM, Surface snow was undisturbed with large stellars mixed with small surface hoar. Skies cleared in PM. Ski pen 25 cm, HST 90 overlying the Early Feb interface. HS was 180cm near the ridge top.
