Quick report

Two pits showed notable contrasts in snowpack structure and stability tests between a deeper slope (175 cm) and a shallower slope (123 cm).  In the deeper slope, weak layers in the upper snowpack (2/2 and above) looked relatively strong and produced non-propagating results.  I could feel weaker depth hoar near the ground with the probe, but seems out of range for triggering in wind-protected terrain where snow depths are more consistent.  In the shallower snowpack, the February 2nd layer still has the signature stripe, is fist hard, and produced hard, propagating results 2 feet deep.  The depth hoar below it looked equally weak 3 feet deep.  I think this terrain feature has avalanched earlier in the season making the snowpack shallower, and winds may have eroded this slope too.   

Minor sluffing in the upper few inches of moist snow on steep features.
