Broke a small wind slab on Sluice Box

A small wind slab broke as I was skiing down Sluice Box near the weather station on Bridger Ridge. Crown was about 8 feet wide and the slide path looked to be about 60 feet. I was out of its way and unharmed, gave me a pretty good scare though!

Notes
The skiing was good and non reactive on the main East face next to the skin track. The North gullies into Naya Nuki creek and the the lower/steeper gullies to the south were highly reactive and entraining lots of snow.

Notes
Skied the Banana today with 8-12” of new snow that has mostly bonded. The snowpack below the new snow had froze over night and was well consolidated.
Observed a layer of graupel (3-4mm grains) at the new/old interface on the NE ramp starting at 8600’ and clearing up after 8700’. This layer created some reactivity in the storm snow.
Wind slabs <6” had formed on N and NE aspects. We had one small release in the bottom of the couloir measuring ~10x20’ and running ~50’.

The 12" of snow since yesterday fell right-side-up and had little to no slab properties. This new snow rests on a stout melt-freeze crust from the high temperatures last week. Photo: GNFAC

Other than that, the skiing was amazing and manageable.
