Written Report:
I traveled on south, east and northeast slopes near and above treeline. There was about 5 cm (2') of recent new snow. The snow surface in the direct sun was getting cooked. I found roller balls and very small natural loose wet slides on south through east aspects near and above treeline.

There was some wind affected snow near ridge lines, but I did not find any windslabs.

Although not widespread, there are some small cornices hanging over the cliff bands on the east side of Broken Top.

I dug into the snowpack on a NE facing slope near treeline. I did not find any weak layers in the upper 60 cm.

After 2pm, when the east facing slopes were in the shade, a surface crust began developing.

There has been 10 - 15 cm of settlement in the snowpack over the last week, although I was still measuring over a meter of snow in most areas I toured.

Around noon, the air temperature on the ridgetop of Ball Butte at 7800ft was 8 C (46 F). Wind was light out of the SW throughout most of the day.

It was a pleasant day in the mountains and I found some good skiing conditions on SE and E facing slopes near and above treeline.
