Bears are active in Grand Teton
Black and grizzly bears are roaming throughout the park--near roads, trails and in backcountry areas. Hikers and backcountry users are advised to travel in groups of three or more, make noise and carry bear spray. Visitors must stay 100 yards from bears. More »
Multi-use Pathway Closures
Intermittent closures of the park Multi-use Pathway System will occur through mid-October during asphalt sealing and safety improvement work. Pathway sections will reopen as work is completed. Follow the link for a map and more information. More »
Moose-Wilson Road Status
The Moose-Wilson Road between the Death Canyon Road and the Murie Center Road is currently open to all traffic. The road may re-close at any time due to wildlife activity. For current road conditions call 307-739-3682. More »
Park Officials Troubled by Increase in Wildlife-Vehicle Collisions

Grand Teton National Park plans to redouble efforts to reduce wildlife-vehicle collisions on park roads. Each year, motor vehicles cause the deaths of well over 100 animals, resulting in a significant toll to park wildlife. Over the past few years, park rangers and biologists have documented trends related to wildlife-vehicle collisions in an attempt to make park roads safer for both people and animals.
Since 2000, the number of animals killed on park roads has steadily increased. In fact, a 31% rise in wildlife-vehicle collisions occurred between 2008 and 2010. While an average of 104 animals are killed annually on park roads, an unparalleled 162 vehicle-caused deaths were tallied in 2010 alone. Included in the 2010 data were 48 elk, 41 deer, 17 bison, 6 pronghorn, 5 moose, 5 bears, and 2 wolves. Park biologists believe this tally is likely higher as some collisions are never reported. This unprecedented increase in vehicle-caused wildlife deaths came despite a proactive education/ prevention campaign launched in 2006.
Records of wildlife-vehicle collisions indicate certain trends and patterns. Statistics show that most of the accidents occurred between dawn and dusk along Highway 26/89/191 between Moose and Moran junctions where the speed limit is posted as 55 mph. A number of collisions also occurred between the Gros Ventre River Bridge and Jackson Hole Airport Junction. Drivers involved in wildlife collisions were almost equally as often local residents as they were out-of-state visitors; most commonly the drivers were males traveling alone or with one passenger. Speed was often the biggest factor in these collisions, particularly at night when drivers exceeded the range of their headlights. Motorists who overdrive their high beams-when the stopping distance is greater than the headlight illumination distance-are less able to stop or slow down with the sudden appearance of an animal on the road. Drivers are cautioned to observe posted speed limits and even reduce their speed, especially at night.
Park managers plan to implement new prevention measures in an effort to reverse the recent trend in animal deaths from vehicle collisions. Flashing message boards will be placed at various wildlife crossings and collision hotspots; and stationary signs will be posted at seasonally active areas. In addition, the Highway 26/89/191 speed limit will be reduced to 45 mph from the park's south boundary to Moose Junction while construction of the multi-use pathway is underway. During this same time, park staff will closely monitor wildlife-vehicle collisions to determine if there is a related decline in animal deaths. Data collected will inform future decisions about possible actions that can be taken to control traffic, such as seasonal speed limits to slow vehicles during wildlife migrations on Highway 89 in Grand Teton National Park. Rangers may also increase patrols to educate motorists about being alert for wildlife and enforce speed limits.
Park roads wind through expansive sagebrush flats-and through some of best habitat in the country for elk, deer, bison, pronghorn, moose and bears. The same conditions that make Grand Teton a global destination for wildlife-viewing also make it a challenge for wildlife-vehicle collisions as animals regularly cross and travel near park roads. Park officials remind motorists to stay alert, slow down and give wildlife a break-especially during low-light conditions from dusk to dawn when animals may be difficult to see. Drivers should expect the unexpected with regard to wildlife that travel near and across park roads.
The reduction of vehicle-caused wildlife deaths is everyone's responsibility.
Did You Know?
Did you know that Grand Teton National Park was established in both 1929 and 1950? The original 1929 park protected the mountain peaks and the lakes near the base. The boundaries were later expanded in 1950 to include much of the adjacent valley floor.
