Natural Avalanche Mt Republic - Cooke City
Cooke City, 2014-01-05

This natural slide occurred on Mt. Republic near Cooke City. The slide took place on an east facing slope around 9,200 ft. and likley failed on facets 1-2 feet above the ground. Photo Beau Fredlund 

Avalanches south of Mt. Blackmore
Northern Gallatin, 2014-01-04

Two recent avalanches were spotted just south of Mt. Blackmore in the northern Gallatin Range yesterday (1-3-14). Photo: B. VandenBos

Blackmore Avalanche
Northern Gallatin, 2014-01-04

This slide occurred in one of the meadows along the trail to Mt. Blackmore just before the trail climbs out of the Blackmore Creek drainage into the Blackmore basin. This slope gets heavily windloaded at the top. Photo: B. VandeBos

Active wind loading in Hyalite
Northern Gallatin, 2014-01-03

Active wind loading will make many slopes prime to be triggered or to slide on their own. More wind and more snow is expected. Photo: B. VandenBos

Natural avalanches in Hyalite Canyon
Northern Gallatin, 2014-01-03

These two recent avalanches were spotted just north of Hyalite Peak yesterday on a SE aspect. Seeing naturally triggered avalanches means we can easily trigger slides if we ride in avalanche terrain. Photo: B. VandenBos

Overview of Onion Basin Avalanche
Northern Gallatin, 2014-01-02

The crown from this avalanche that resulted in a fatality as well as one from another recent avalanche can be seen in this photo. Photo: GNFAC

Onion Basin avalanche debris and burial locations
Northern Gallatin, 2014-01-02

The full burial occurred just out of view of the photo near the toe of the debris. Photo: GNFAC

Avalanche Starting Zone - Onion Basin Fatality
Northern Gallatin, 2014-01-02

Faceted snow near the ground was the obvious weak layer in this avalanche. The crown was 1-3 feet deep and propagated 150 yards wide. The slide either failed naturally or was triggered from low on the slope. Photo GNFAC 

Avalanche Crown - Onion Basin Fatality
Northern Gallatin, 2014-01-02

This slide caught two snowmobilers resulting in one fatality. The slide either failed naturally or was triggered from low on the slope. Photo GNFAC

Tracks leading into the scene
Northern Gallatin, 2014-01-02

Tracks in this photo show where 2 riders entered the area right before the avalanche occurred. A third rider did not arrive until about a half hour after the avalanche happened. Photo: GNFAC

Partial Burial
Northern Gallatin, 2014-01-02

One rider was partially buried in these trees. His snowmobile was buried there as well and one of the skis is visible. It took him approximately 30 minutes to dig himself out. Photo: GNFAC

Sunset on Gallatin Crest
Northern Gallatin, 2014-01-02

Sunset on the Gallatin Range crest.  An avalanche left of the ridge was likely triggered by a cornice breaking. Photo: B. VandenBos.

Large natural avalanche near Divide Peak
Northern Gallatin, 2014-01-02

Large slide just down the ridge to the west of Divide.  It looks like this was triggered by the collapse of a big cornice. Photo: B. VandenBos

Avalanches on Divide Peak
Northern Gallatin, 2014-01-02

Numerous slides west of Divide Pk.  Strong winds were loading both over the top of this ridge as well as along slope from left to right. Photo: B. VandenBos

Cooke City, Miller Ridge
Cooke City, 2014-01-02

From Beartooth Powder Guides, "Today, on a tour up Sheep Creek, I found protected North facing powder about 18" deep and perfect riding conditions. Saw large new snow avalanche off of Miller Ridge on West,SW slope that looked like it had just happened this AM. Pretty broad (100 yards wide in the run out zone)." Photo: B. Zavora

Above Fairy Lake
Bridger Range, 2014-01-01

Mark Staples found 7 inches of dense (15%) new snow on a snowpack almost 5 feet deep.  Two feet off the ground facets broke in the Extended Column Test.  It's taking more force to get this layer to break, which is a sign of stengthening.  Photo: GNFAC

Buck Natural Avalanche
Northern Madison, 2014-01-01

This small slide occurred just off Buck Ridge in 1st Yellowmule. It occurred without a human trigger which is a bad sign. Avalanches happening on their own, mean we can easily trigger them. Photo: B. Ashe

Avalanche near Lionhead
Lionhead Range, 2013-12-29

A group of riders near Lionhead were riding on small but steep slopes. One rider got stuck and his buddy came to help dig him out. The slope avalanched burying multiple sleds and one rider up to his neck. Nobody in the group was carrying rescue gear. Photo APG

Teepee Basin Small Avalanche
Southern Madison, 2013-12-28

This slide occurred in upper Teepee Basin. It was snowmobile triggered. Photo: GNFAC
