Written Report:
I attempted to get into the high country near Ball Butte/broken top to check on the wind slab and cornice formation, but the visibility above treeline was absolutely zero.

I toured into the Todd Lake area. Snow was falling during my tour, however with the air temperature hovering around 0C (32F) the snow was very wet. I found 2-3 cm (1") of new snow on top of 20 cm (8") of slushy saturated snow. I did not travel on steep terrain, but I can envisage loose wet avalanches happening on steep terrain today and possibly wet slabs on convex/unsupported terrain. The temperature is expected to drop significantly tonight, so if we get a solid freeze, I expect these problems to subside.

No other signs of unstable snow were observed.

Ski quality was ok. The east facing glades below Todd Ridge were smooth, but the snow was a little sticky.

Wind was light out of the SE to SW. Light amounts of blowing snow was observed at ridgetop (6800ft).
Temperature: -0.5°C Precip: S-1 Very light snow Wind: Southwest @ 1-16 mph
New Snow: 3 cm Elevation: 6800 ft
