SPRING UPDATE - APRIL 5, 2024

 

Photo taken from Moose Jct. - 4.5.24
Snow coverage in the range and on the valley floor remains decent and spring corn snow is trying to form between snow events.  But as is typical in the Tetons in spring sustained clear and cold for very many days in a row can be illusive, as evidenced by an incoming storm tonight. Backcountry travelers should be prepared for the full gamut of winter and/or spring like conditions and expect abundant snow.  Please continue to check the latest avalanche forecast and snowpack information before your ventures.

Bighorn sheep closures remain in effect through April 30th. Help us protect this iconic species by knowing the location of and abiding by the closures.  Click here for the latest closure map. 

Backcountry permits are required year-round for any overnight travel inside Grand Teton National Park and are available and issued by phone during this time. See November 1, 2023 post for details.

All Park Visitor Centers and Campgrounds are closed for the winter season.  Camping is strictly prohibited in parking areas and pullouts.

  

TETON SNOWPACK DEEPENS - FEBRUARY 17, 2024

 

Taggart Parking was BUSY on this fine winter day! - 2/17/24
Two solid and lengthy storm cycles during the month of February have left the Teton Range with a healthier snowpack than we had a month ago.  Snake River Basin SWE % increased from about 73% to 89% during the past month.  Avalanche danger remains considerable today as the range adjusts to this latest loading event.  Please stay vigilant and stay up to date on the latest avalanche forecast and snowpack information before you head out into the hills to enjoy the fresh snow.

Please help us protect our bighorn sheep population by abiding by winter wildlife closures and voluntarily avoiding critical habitat zones.  Click here for the latest closure map.

HAPPY NEW YEAR - AVALANCHES EVERYWHERE! JANUARY 13, 2024

 

The Teton Range - Photo Taken 1/13/24
After the first legitimate storm cycle in weeks, the Teton Range is, unsurprisingly, literally littered with avalanche debris everywhere you look.  An uncountable number of avalanches were revealed this morning after the range received recordable snowfall eight out of the last nine days.  This storm snow put a significant load onto a dehydrated and feeble snowpack that developed during the extensive drought we experienced for most of December.  It is more important than ever to stay vigilant and stay up to date on the latest avalanche forecast and snowpack information before you head out into the hills to enjoy the fresh snow.

HAPPY HOLIDAYS - ASK SANTA FOR SNOW! - DECEMBER 16, 2023

 

Buck Mountain and Mt Wister on 12/13/23
Winter is off to a slower, yet not-too-atypical, start this season in the Tetons.  We are generally sitting below average for snow on the ground in the mountains and the valley, although it is much more noticeable in the valley bottom. As we move into the winter season please be aware of a few reminders and some new things as well...

FALL UPDATE - OCTOBER 14, 2023

Photo taken 10.13.23

Temperatures have cooled enough that snow on east and south aspects is not melting above approximately 10,500.'  Please read the September 20, 2023 post for important safety information regarding fall conditions in the Teton Range!  

FALL IS HERE - BE PREPARED! SEPTEMBER 20, 2023

Fall officially starts at 1:00 am on Saturday morning and Mother Nature is planning to celebrate accordingly!  A strong cold front is rapidly approaching us today and will bring cold temperatures and snow to elevations above 10,000 feet.  

While this snow is likely to melt off on east and south aspects, it will not on the north and west ones!  Snow, ice and verglas have been present  since early this month and will remain the rest of the season on the Owen Spalding route, requiring advanced skills and proper equipment to negotiate safely!  All backcountry users should acknowledge the shorter days, cooler temperatures and come prepared with a weather forecast available at www.mountainweather.com

Climbers attempting other popular routes in the Teton Range should be prepared for shifting weather, unexpected alpine conditions, and cold nights, which can produce ice and verglas on multiple aspects and elevations. Weather and climbing conditions in the Tetons can change rapidly with each passing storm. Adequate preparation, appropriate gear, and self sufficiency are of the upmost importance when venturing into the mountains, especially during this time of year.

Backcountry permits are required for overnight trips into the backcountry and can be obtained at the Craig Thomas Discovery & Visitor Center in Moose until October 31st.  Staffing in the park is limited this time of year which can result in slower rescue response times than in peak summer season.

The Jenny Lake ranger station is closed for the season. The staff will make an effort to update conditions for the Grand and other popular peaks throughout the remainder of the month, however, expect cold alpine conditions in the mountains as we move into fall.

UPPER MOUNTAIN SNOW & ICE- SEPTEMBER 6, 2023

 Winter-like conditions exist on the Owen-Spalding Route on the Grand Teton making the route considerably more difficult.  Crampons may help but they do not guarantee a successful ascent. Climbers should be prepared for these conditions to last the rest of the "summer" season.

SNOW ON THE GRAND TETON - AUGUST 5, 2023

The Teton Range and surrounding area has received a fair bit of precipitation the last three days, and is forecasted to receive more precipitation in the upcoming days. Heavy rain showers and large amounts of rockfall have been witnessed in Garnet Canyon, as well as snow above 13,000'. BE ADVISED!! Large amounts of precipitation increase rockfall potential in steep terrain. Be careful when traveling below steep terrain during prolonged heavy precipitation events. 

Travel to and from the summit of the Grand Teton the last couple of weeks has been void of ice and snow. BE ADVISED!! These conditions have changed. Be on the lookout for snow and verglas when traveling in the higher elevations. 

Conditions will continue to change this week as cooler temps and more precipitation move through the Teton Range. 

MOUNTAIN CONDITIONS UPDATE - JULY 22, 2023

Backcountry trails and popular climbing routes are overall in good condition. Snow levels have receded across the park, and most divides and passes on the Teton Crest Trail are dry. Trekking poles and micro spikes are useful but are no longer necessary across Paintbrush Divide. Buck Mountain Pass, however, still holds a steep snow crossing.

Buck Mountain Pass - 7/19

For updated conditions on the Owen-Spalding route, please visit the climbing route conditions page.

SUMMER WEATHER HAS FINALLY ARRIVED-JULY 9,2023

 We are finally experiencing proper summer weather here in Grand Teton National Park.  Valley temps have been reaching the mid 70's the last few days and high temps at the lower saddle have been in the low 50's.  With more warm dry weather in the forecast the time is now! Get out and enjoy it!

SECTION OF VALLEY TRAIL CLOSED - JULY 1, 2023

 Effective immediately, a section of the valley trail is closed due to an active Goshawk nest.  Hikers have reported numerous "dive bomb" attacks.  Closure is from the Taggart Loop Junction to the Death Canyon Junction.  See map.


 

GRAND TETON: OWEN-SPALDING CONDITIONS UPDATE - JUNE 22, 2023

Multiple winter storms have impacted the upper mountain in the recent weeks. Travel on steep, exposed snow is unavoidable above the Petzoldt Caves camp zone.  Summer route is recommended from the meadows to the moraine camping zone, and from the moraine to the Lower Saddle, the winter route is still the best option. Be especially aware of exposure to recent rockfall anywhere below the summer route "fixed lines". From the Lower Saddle to the summit, expect to encounter winter climbing conditions, including ice, snow, and verglas. Crampons and ice axe are highly recommended for safe travel up the Grand Teton as of today.

SIGNIFICANT ROCK FALL BELOW THE LOWER SADDLE FIXED LINES!!! - JUNE 16, 2023

Select "Lower Saddle Approach" under the "Climbing Route Conditions" tab for more detailed information. 

SPRING RAIN- JUNE 7, 2023


Rainfall and warming temps this week are accelerating the snowmelt. Depending on which canyon you choose to visit, the first 3-5 miles will be clear of snow. Beyond that, you will find patchy snow eventually leading to all snow. 

The valley is blooming with Balsam Root, Lupine, and Larkspur, and the valley trails are mostly, if not all dry. 

BAXTER'S PINNACLE CLOSED - MAY 31, 2023

Effective immediately, the Baxter’s Pinnacle area is closed to public entry.  This closes the Baxter’s Pinnacle climbing route to human traffic as well as the social trail that branches from the horse trail and serves as the approach route to the climb.  The National Park Service has determined that the closure is necessary for the protection of nesting peregrine falcons and their young. The peregrine falcon is a state Species of Greatest Conservation Need and is protected under the Migratory Bird Treaty Act.

Backcountry conditions in the valley are much improved, but patchy snow still remains scattered about.  The canyon trails remain mostly covered in snow and hikers should expect difficult travel and route finding at higher elevations.  Sturdy boots and and ice axe/crampons are required for travel over any mountain passes.  

The visitor center in Moose is now open and park information and backcountry camping permits can be obtained there from 8am to 5pm.  Backcountry camping permits and bear canisters are required for all overnight trips into Grand Teton NP. 

GETTING BETTER, BUT NOT GREAT - MAY 24, 2023

The snow continues to rapidly melt but we are still a long way out from summer-like conditions.  Trails on the valley floor are a mix of patchy, slushy snow with numerous areas of deeper snow and many down trees.  As you move into the heart of the canyons, expect nearly 100% snow cover.  A volunteer ranger attempting to reach the Death Canyon Shelf a couple days ago, fell through to his knees immediately after departing the top of the aerial Tram at Jackson Hole Mountain Resort.  He was wearing skis!!  Travel in the hills is still difficult to say the least.  Please be prepared for these conditions and stay safe out there.
