Written Report:
I toured along the east side of Ball Butte and Broken Top en route to the Bend Glacier on the northeast corner of Broken Top.

I dug down 1 meter (3 feet) in the snowpack on a north aspect above treeline on the Bend glacier. I did not find any buried surface hoar in this location. Throughout the tour, I traveled on flat terrain as well as north, east, and south aspects above treeline. I did not encounter any slope collapse/wumphing that is often associated with buried SH. No avalanches were triggered.

Wind slabs from the previous storm were found in isolated areas on north and east aspects. The wind slabs appear to be bonding to the snow below. I observed no cracking or slabs moving when traveling over wind slab.

Isolated cornices were found at ridgetops on east and north facing slopes. Some of the cornices have become quite large. Watch for them on these warm sunny days when they can weaken and fall!

Small loose wet avalanches were observed on east and southerly slopes above treeline. We are moving into the season when loose wet slides become more common on these warm days.

The only signs of slab avalanches I observed were previous (days old) size D1 wind slabs in pockets of steep terrain on high east and north facing slopes.
