Here's another one:The way this "winter" started is reminiscent of a few past years. On some years where the ground is very warm (recall that temps at 5000' were near 50 degrees during the heavy rain event), and snow accumulates suddenly, the new snow tends to insulate the ground/snow interface from freezing up - the snow at the base of the snowpack will tend to be very wet and weak for as long as a month or two. So, especially on steep, south-facing grass slopes; and especially during or after warming, or sometimes just with steady snowfall, slopes may fail at the base of the snowpack. This last happened in the fall of 1997.
Whether one can trigger this type of snowpack or whether it just gradually releases, who knows? But is worth thinking about, especially if grass slopes are very steep (most face south or west in our climate).
