A few inches of new snow combined with moderate winds from the southwest to begin loading Tumalo's east facing bowl. The first turn into the bowl by the snow machine zone produced cracking and a VERY small avalanche (see picture). There were lots of tracks elsewhere in the bowl and no substantial avalanches, but this cracking is a good clue that wind slabs likely exist throughout the range at and above treeline. They are also likely to increase in size as more snow continues to fall.
During my midday tour it snowed most of the time, but there were some short breaks when the sun would filter through some high clouds. There was approximately 7-10 cm. of new snow. At and above treeline the wind was light-moderate from the southwest. On top of the butte around noon, there was moderate blowing snow. It stayed below freezing throughout the day.
