<p><span><span><span><span><span><span>Recent heavy snowfall has created dangerous avalanche conditions and human triggered avalanches are likely. The mountains near Bozeman and Big Sky received 2-4 feet of snow since Wednesday (2-4” of snow water equivalent), and an avalanche warning was issued on the last two days. The warning expired today, but the snowpack is still unstable with a variety of buried weak layers. Over the last two days, people reported many large natural and human-triggered avalanches: </span></span></span></span></span></span></p>

<p><span><span><span><span><span><span>Similar avalanches can be triggered today, would have large consequences, and can be triggered on steep slopes or from lower angle terrain below steep slopes. Until the snowpack has adjusted to this recent storm, your safest plan is to avoid travel in avalanche terrain. Today, large human-triggered avalanches are likely and avalanche danger is CONSIDERABLE.</span></span></span></span></span></span></p>

Multiple natural avalanches were seen on all aspects, all elevations near Woody Creek Cabin. Poor test scores (ECTP) in 4/6 pits, mostly beneath the snow that fell earlier this week, buried small grain facets and decomposing surface hoar.
While snowmobiling up Little Bear we witnessed this natural avalanche. There was 2-3' of new snow.

There were numerous debris piles, point releases, and crowns on the north face of Elephant and the northeast face of Blackmore this morning. Most of them appeared to have run during the storm (1/27) and had been covered by at least 6 inches of new snow.
