AVALANCHE ACTIVITY INCREASED DURING MAJOR STORM - DECEMBER 11, 2012

Beginning December 1st, snowfall has been daily and snow totals have reached 4-5 feet above 9500'. This past weekend, dense wind driven snow increased the stress on the snowpack, triggering some of the first large avalanches of the season.  Here in the Tetons these large avalanches occurred on north and northeast aspects.  Looking at the November 7th photo below we can see the old snowline where the October weak layer likely exists today. 


ANOTHER SHOT OF SNOW THIS WEEKEND, LET IT SNOW! - NOVEMBER 7, 2012


The first storm of this season brought 2-3 feet of new snow to the mountains, but another warm and dry period melted it back to an elevation of 9,000'.  The reports of warm, south facing rock climbing may be coming to an end.  The second winter storm is predicted for this weekend with more snow in the mountains and cold temperatures.

FALL'S FIRST BIG SNOWFALL - OCTOBER 17, 2012


 Mt Owen and the Grand from Cascade Canyon - 10/17/12
After a long, hot, and dry summer and fall, the Teton Range finally received its first good dose of moisture over the past two days.  Hard rain and hail in the valley and significant snowfall in the high country left behind snow-coated peaks above 8,000 feet.  Today's sunshine was already beginning to melt the snow below 10,000 feet, but it's safe to say that it is here to stay above that elevation.

FALL UPDATE - SEPTEMBER 24, 2012


Clouds drape over the high peaks of the Teton Range - 9/24/12
After two weeks of hot and smokey weather, the Teton Range is experiencing another period of unsettled weather with precipitation expected in the high country.  As we move into fall, climbers and hikers should be prepared to deal with the changing conditions, including: 

  • snow, ice and verglas in shaded areas, especially on north and west aspects above 11,000 feet
  • freezing overnight temperatures - don't count on water at the Lower Saddle!
  • shorter days - usable light only lasts until about 7:30 - 8:00 pm 

Specific route condition updates will be limited as we move into fall and staffing is reduced to winter levels.  The HOMEPAGE will continue to provide updates on general conditions in the Teton Range throughout the winter.
