Today we had intentions of finding some consistent snow (powder) that had not
been affected by the winds of 12/23. Pit results in this area were “middle of
the road”. Strength tests were moderate. The snowpack structure is poor, but
better than what we have been seeing in other areas around Turnagain. We
decided to ski into an area that had slightly steeper terrain and experienced a
decent sized collapse. Rather than push terrain angle for the sake of better
snow we backed off once we experienced the collapse. Today was a good reminder
that obvious signs should always trump any sort of in depth analysis.
