April has been relatively cool and snowy so far, continuing to add to already near-record snow depths above 9,000 feet.  Settled snow depths at this elevation range from 7-12 feet and settled cold/dry snow is prevalent at and above these altitudes.  Localized wind slabs continue to be an issue at these higher locations throughout the Teton Range (Recent Rescue Report).  On top of all that, backcountry users must continue to be aware of wet avalanche hazard, especially during periods of warming afternoon temperatures.  Evidence abounds of wet snow releases on slopes at all elevations and aspects.  

The coming spring is more readily apparent at the lower elevations as creeks are beginning to open up and bare ground is starting to show.  Be extremely cautious of lake crossings as we move into late April and May as they may no longer be a safe option for cross country travel.

As a reminder all overnight backcountry camping requires a permit that can be obtained at the Craig Thomas Discovery & Visitor Center in Moose between 9am and 5pm.  Food Storage utilizing bear canisters is required in Grand Teton National Park for all overnight stays in the backcountry.

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.
