Signs of Unstable Snow

Observations

After discussing conditions we selected an assessment mindset for our tour up the alpental vallley this morning. We sought to avoid terrain traps that may have been buried by the recent storms, slopes 35 degrees, and convexities we suspected may harbor wind slabs. We encountered multiple terrain traps enroute, including open drainages above and below source lake. We decided to travel the slopes above source lake to take snow depth measurments and conduct a column test.
