Record snowfall and early bear sign

As of March 13, 2017, we have received over 536” of snow for the season. This means that there will be a fairly high likelihood of snow remaining on mountain passes and in the high peaks deep into the summer months. If you are planning a backcountry trip this summer it will probably be prudent to bring an ice axe and the knowledge of how to use it.

Last week bear tracks were seen, and confirmed, in the high country of Yellowstone National Park. As we are beginning to move into spring be diligent with proper food storage and think seriously about bringing bear spray with you if you venture into the backcountry. Mandatory food storage requirements are in place and will be strictly enforced.

Valley lakes are experiencing surface flooding, use caution and prepare for alternate trips.  


It has been a busy winter in Grand Teton National Park, with near-record amounts of snow in the mountains and the valley.  The continuous severe winter weather has kept rangers busy with highway closures, highway bison herding, numerous vehicle slide-offs and accidents, plus a handful of backcountry rescues to boot!  Teton Village lost power for nearly a week after the most recent major storm system knocked down several large power lines about two weeks ago!

The Teton Range currently has a very deep snow pack with settled snow depths of around eight to eleven feet at the 9,000 foot level.  For detailed information on the current avalanche hazard in Grand Teton National Park, please visit the Bridger-Teton Avalanche Center website.

Recent storms have deposited more snow throughout the range. Expect to encounter significant amounts of unconsolidated snow above 9,000 feet, below that elevation the snow coverage is roughly 4-6 inches. For the most up to date snow conditions please refer to the Bridger Teton National Forest Avalanche Report at: http://jhavalanche.org/viewTeton , pay particular attention to the Snowpack Summary.
As of November 22nd none of the valley lakes are frozen over.  


We have received quite a bit of snow and rain over the last 10 days. This past weekend we experienced warmer temperatures in the valley, but most of the snow above 10,000 feet stayed, so expect ice and snow to linger in shaded areas and north facing peaks. Cold mornings and shorter days have not allowed for melting in these areas and any new storms will most likely compound existing winter conditions. Most of the classic couloirs, like the Black Ice Couloir, have not received enough melt-freeze to make for adequate alpine ice. This is not a good time of year to attempt long climbs for the first time and climbers should be prepared for rapidly changing weather patterns.
