Cold and clear, with a fair amount of solar radiation in the afternoon. The sinks read -10 this morning, driving through. The trailhead was in the teens. Throughout the day, it warmed to the mid 20's. Solar aspects warmed and became a bit heavy by mid-afternoon, cooling off back to the teens at sunset.

35cm of great cold low-density powder on top of a stout melt-freeze crust. This 10cm melt-freeze crust has a significant amount of 2mm+ grauple on top. Directly below the crust is a very rotten layer of large facets. All snow in the lower 45 cm, below this crust is very wet.

Problem #1 Comments
Based on observation, concers lie both on top and below the firm melt freeze crust in the snowpack. The wet snow below this crust seems to be setting up nicely. I am leery of the steep, cold northly slopes

Comments
I was surprised at the quality of the riding today. Generally, we found 79cm-95cm of snow above 7900'.
I am leery of the steep, upper elevation, cold northly slopes; the rest of the compass seems to be well on its way to healing with plenty of moisture in the lower snowpack.
