Northern Gallatin

We dug near the top of Bacon Rind and found 155cm of snow. Our primary concern is with the upper snowpack. As it warms and wets we can expect an increase of avalanche activity on the ice crusts. Facets are still dry and soft at the bottom of the pack and I got this layer to break with an ECTP29. Photo: GNFAC

Natural Cornice break and wet loose in Alex Lowe Basin

Notes

From the Blackmore/Elephant saddle I observed what looked to be a less than a day old cornice break which triggered a loose wet slide in front of it. The cornice debris was large, about the size of a VW beetle. Also observed some surface hoar on the north side of the saddle.

Cornices have grown rapidly in the last few days. These will be susceptible to breaking and could trigger pillows of wind slabs under them. Photo: Bridger Bowl Ski Patrol
