Mt. Jefferson Avalanche 1 Mar 9, 2010 - Mt. Jefferson Avalanche 1 -

A snowmobiler triggered this slide around 2pm on a southeast facing slope.  No one was caught.  Photo: Derek

Surface Hoar - Sunlight Basin Mar 6, 2010 - Surface Hoar - Sunlight Basin -

These large potato chip like surface hoar crystals were found on north facing slopes in Sunlight Basin and other north facing slopes in the Taylor Fork.  These large crystals formed in less than two days and will more than likely be a problem when it snows again.   
Buried Surface Hoar Sunlight Basin Mar 6, 2010 - Buried Surface Hoar Sunlight Basin -

These two layers of buried surface hoar are being found on most north facing slopes, but are showing signs of strenghteing. 
Argentina Bowl Crown Mar 4, 2010 - Argentina Bowl Crown -

This avalanche was triggered by skiers who dropped a piece of cornice.  It did not propagate widely but broke deep and ran far through trees and over rocks. Photo - Anonymous
Argentina Bowl Avalanche Mar 4, 2010 - Argentina Bowl Avalanche -

Skiers dropped cut a piece of cornice and triggered this slope in Argentina Bowl just south of Saddle Peak.  Even though this avalanche did not propagate widely, it broke deep and ran far through trees and over rocks, a painful ride at best.  Photo- Anonymous
Hyalite Avalanche Mar 1, 2010 - Hyalite Avalanche -

The avalanche ran over steep terrain mid path.  You can see the debris curving away outside the right side of the photograph.  It ran 1,200 feet and pulled out the entire winter's snowpack.   Photo: Wykoff. 
Hyalite Avalanche 2/3 Mar 1, 2010 - Hyalite Avalanche 2/3 -

This slide broke on an east facing slope near the ridge from skiers kicking off a large cornice.  It was a hard slab of wind compacted snow at the crown.  Photo: Wykoff
Hyalite Avalanche 1/3 Mar 1, 2010 - Hyalite Avalanche 1/3 -

The slide broke on facets near the ground. Skiers kicked off a cornice on the ridge which avalanched the slope. It looks to be 3-5 feet deep.  Many potential trigger points can be seen as this slide uncovered previously buried rocks where the snowpack was thinner. Photo: Wykoff
Easy shears in the Northern Gallatin Range Feb 28, 2010 - Easy shears in the Northern Gallatin Range -

Skiers got very easy and clean shears with the ECT in open terrain.  They were surprised at this result yet heeded its warning and skied lower angled slopes.  This soft slab likely failed on a layer of small grained facets formed at the surface a few weeks ago. Photo: Anon
