Northern Madison Range
The mountains near Big Sky received 12 inches of snow yesterday containing 0.9 inches of SWE. Most of this snow fell during a 7 hour period. This area received 0.4 inches of SWE the previous day. Avalanches will be likely within the new snow especially on any wind loaded slope. The Big Sky Ski Patrol easily triggered shallow wind slabs yesterday with ski cuts.

At least 7 avalanches were seen yesterday (3/26) on SW aspects in the Jones Creek area on the west side of the Bridger Range. All were several days old. Three of them stepped down into wet snow and created large debris piles. Photo: A. Whitmore

The circle shows my pit location on a south-facing slope. We did not ski this slope because my stability tests were inconclusive on a layer of depth hoar found one foot off the ground. I do not trust this layer and try to avoid areas where thin, rockier terrain underlies the snowpack, which this slope has. Photo: GNFAC
