Fair visibility allowed viewing of adjacent ridges but not much more. Light snow seemed to pick up a little in the afternoon but didn't really amount to much. Winds were light. Relatively warm.

Light winds and clouds/no sun kept the snow surface in good shape in protected areas.  Usual areas right along ridgelines were wind scoured.

Snowfall and associated loading from the past few days was the only red flag observed today. Surprisingly light winds even during the storm - winds at 9990 averaged mostly ~10 mph or less since Friday.

Problem #1 Comments
New snow seemed well behaved and many slopes along the Park City ridge line near 9990 were skied without problem.
 
It did seem like there were some unusual wind loading patterns from say the past month that have been covered by the most recent snow.  For example, places that normally didn't have cornices now have them.  Large drifts of snow are present even relatively far off ridge lines.

Overall very strong, stable snow.  Pit was in a bit of a shady spot and did note some rounding facets about 1m deep.  These were rounding and unreactive in snowpit test.
