Written Report:
Climbing up the west side of Tumalo I saw a mixture of old preserved powder in the trees, ski penetration up to 2" (5cm), and supportable melt freeze crust on more open solar aspects.

At 12:10pm on top of Tumalo the skies where clear with light to moderate winds out of the east. Total height of snow was 65cm (26"), air temp around 1C (34f). There was no blowing snow.

The bowl itself was a mixture skied up old snow and wind affected snow. Digging into the snowpack I did not see any signs of instability, I did not see any evidence of avalanches. No cornice formation at the top of the bowl.

At the bottom of Tumalo bowl (7235') , on an east aspect, I dug a pit and found a crust 52cm (21") down. This crust was very well bonded to the snowpack above and below. CTN. See pic.
