Three to six inches of new snow was seen touring from Bunny Flat above treeline on Green Butte Ridge. Blocking, cracking, and column tests indicated the possible presence of a storm slab breaking just below a sun crust below the new / old snow interface. A sugary faceted layer with 0.5 mm grains exists below an ice crust about 78 cm down. Failures on this layer were moderate to hard. No notable ECT failures were achieved.

No signs of a wind slab problem were seen. Snow surfaces below, near, and above treeline had no wind affect. Winds were unusually calm to light.
