Beginning Friday, May 1st, an area including Baxter’s Pinnacle and its southwest descent gully will be closed due to an active peregrine falcon nest.

In 2011, a peregrine falcon pair established a new nest near Baxter’s Pinnacle; this is the fifth year in a row that a closure will be levied to protect both climbers and falcons. As the peregrines reclaim this previous nest area, it is an especially critical time for them; therefore, it is important that climbers comply with the posted public closure.

Peregrines are territorial and aggressive birds especially while nesting and incubating eggs; they become even more protective after their chicks hatch.  This area will remain closed indefinitely until the young birds have fledged or biologists determine there is no longer a risk to either climbers or the falcons.

The peregrine falcon is among the world’s fastest birds, flying at 40-55 mph and diving at more than 200 mph while defending territory or striking prey. This poses a safety risk to climbers who could be knocked off the route and injured.

Backcountry camping permits are required year-round for all overnight trips into the backcountry of Grand Teton National Park.  Climbers and hikers can obtain backcountry camping permits at the Craig Thomas Discovery & Visitor Center.  Detailed information can be found in the links on the right.

LAKE ICE UNSAFE! - April 24, 2015

BEWARE!  The lake ice on the valley floor is unsafe.  A visitor fell through ice on Leigh Lake a few days ago and rangers in the Colter Bay District are reporting that Jackson Lake is no longer safe for travel.  The outlet area of String Lake is completely open water and Jenny Lake has open water showing along the shoreline and among several interior cracks and pockets.  Please be extra cautious around all valley lakes in the Park!  

Jenny Lake ice looking thin and weak!  - April 24, 2015


An unseasonably warm and dry February and March has left Jackson Hole with a thin and rapidly disappearing snow pack as we head into April.  Snow-free south facing aspects below 8,000' are no longer the exception, but are becoming the rule, as the impact of the sun's increasingly stronger rays becomes greater.  The Teton Park Road between Taggart Lake Trailhead and Signal Mountain has been plowed and is bare and dry, open exclusively to hiker/biker traffic until May 1st.  The valley lakes are still frozen, however, extra caution is warranted now as the ice becomes thinner and more suspect during the spring thaw.  Above 9,000' winter-like conditions prevail and travelers can expect typical, and extensive, snow coverage in the Teton Range for this time of year.

Stay tuned for more spring updates as we get ready for another Teton summer season!  Stay safe!

Winter climbing conditions prevail in the high peaks of the Teton Range. Climbing and backcountry travel will involve access through avalanche prone terrain. In order to have a safe and successful trip, it’s important to have good route finding and avalanche skills while traveling throughout the range. Be diligent when selecting a route, trail, or campsite in canyons or on peaks while remaining flexible to changing your plan or itinerary depending on the conditions. This information will not change until significant warming occurs in late Spring.

Please refer to the Bridger Teton Avalanche Center for recent postings of backcountry avalanche conditions, but be aware that this information only covers areas up to 10500 feet.

Lake Ice conditions:
All of the park lakes, including Jackson Lake, are frozen and will support skiers and snowshoers in most areas. There are still areas of thinner ice throughout Jackson Lake, be sure to monitor the changing ice conditions and change your route depending on the presence of water, slush, or unusual cracking.
