Y O U R G U I D E T O T H E PA R K • FALL 2018 Changes of Autumn The arrival of autumn breathes new life into Grand Teton National Park. As the heat of summer slowly gives way to the cooler months of fall, changes may be seen across the park. The bright green leaves of the aspens become vibrant yellow; the sun, once bright until late in the evening, sinks below the horizon earlier each day; cool breezes and frequent rain showers wash away the haze of summer. For many animals, fall is the time to migrate to their winter grounds. Bison, pronghorn, and elk begin moving south. Grand Teton is a corridor for many of these animals, and they follow the same path their ancestors took thousands of years before. Pronghorn gather in large groups to head for their winter grounds near Pinedale, WY. For nearly 7,000 years, members of the Teton herd have headed to the Pinedale area where they join one of the largest gatherings of pronghorn on earth. The 150-mile migration is the second longest land migration in the Western Hemisphere. see CHANGES OF AUTUMN on page 6 Bears in Fall Hawthorne, chokecherry, and other berries attract grizzly and black bears to feast on this vital food source. Park rangers will close roads, trails, and other areas if necessary for visitor safety due to bear activity and bear safety.

More information available at go.nps.gov/tetonbackcountry SAFETY IMPROVEMENTS GROS VENTRE ROUNDABOUT Gros Ventre Junction on U.S. Highway 26/89/191 will be under construction through November 2018. Expect traffic delays and plan ahead. The Gros Ventre Road Junction has an average daily traffic volume of approximately 14,200 vehicles and almost 200 bicycle riders during the summer. Safety concerns have been identified at this location, for vehicles, bicycles/pedestrians, and wildlife. A roundabout is the most effective solution. BE PREPARED AND PLAN AHEAD Construction: April–November 2018 Expect: 15-minute maximum delays 5 am–8 pm 30-minute maximum delays 8 pm–5 am No parking/stopping allowed 1/2 mile from intersection. These construction delays should be considered in addition to busy summer traffic. GROS VENTRE ROAD CLOSURE The Gros Ventre Road, which provides access to Kelly and Gros Ventre Campground, may be closed for up to two weeks after September 15 between 9 am and 3 pm. Reroute via Antelope Flats Road. PATHWAY CLOSURE A temporary pathway closure between the Gros Ventre River Bridge and north of the Gros Ventre Intersection will occur for approximately two weeks in late September. Experienced pathway users may travel along U.S. Hwy 26/89/191 on the road shoulder. Grand Teton Guide, Fall 2018 3 GRIZZLY AND BLACK BEARS thrive in Grand Teton National Park and the John D.

Each species also has particular living space or habitat requirements. To learn more about wildlife habitats and behavior, attend ranger-led activities. While observing wildlife, please park in designated turnouts, not on the roadway. Remember animals are adapted to live in this environment. Please do not interfere. OXBOW BEND One mile east of Jackson Lake Junction. Slow-moving water provides habitat for fish such as suckers and trout that become food for river otters, ospreys, bald eagles, American white pelicans and common mergansers. Beavers and muskrats may swim past. Moose browse on abundant willows at the water’s edge. Elk occasionally graze in open aspen groves to the east, while grizzly bears occasionally look for prey. 4 Grand Teton Guide, Fall 2018 WILLOW FLATS BLACKTAIL PONDS North of Jackson Lake Dam. Moose browse on willow shrubs. At dawn and dusk, elk graze on grasses growing among willows. Predators such as wolves and grizzly bears pursue elk calves in early summer. Beavers create ponds by damming streams that also harbor muskrats and waterfowl. Half-mile north of Moose on U.S. Highway 26/89/191. Old beaver ponds have filled with sediment and now support grassy meadows where elk graze during the cooler parts of the day. Several species of ducks feed in the side channels of the Snake River while moose browse on willows. ELK RANCH FLATS TIMBERED ISLAND Stop at Elk Ranch turnout on U.S. Highway 26/89/191 just north of Cunningham Cabin. Pronghorn, bison, elk, and even domestic animals using a grazing permit frequent this area. The open grasses attract a variety of animals. A forested ridge southeast of Jenny Lake. Small bands of pronghorn, the fastest North American land mammal, forage on nearby sagebrush throughout the day. Elk leave the shade of Timbered Island at dawn and dusk to eat grasses growing among the surrounding sagebrush. SNAKE RIVER Jackson Lake Dam south to Moose. Elk and bison graze in grassy meadows along the river. Bison also eat grasses on the sagebrush benches above the river. Bald eagles, ospreys and great blue herons build large stick nests within sight of the river. Beavers and moose eat willows lining the waterway. ANTELOPE FLATS AND MORMON ROW East of U.S. Highway 26/89/191, one mile north of Moose Junction. Bison and pronghorn graze the flats. Watch for coyotes, Northern harriers and American kestrels hunting mice, Uinta ground squirrels, and grasshoppers. Sage grouse, sage thrashers, and sparrows also frequent the area.

Grand Teton Guide, Fall 2018 5 Changes of Autumn continued from cover Members of the ungulate family – such as elk, deer, and moose – find their mates during the fall months. Listen for elk bugles in the park—a key sign of fall. Bull elk will gather harems of cow elk, then challenge other males to establish dominance. These challenges include bugling and sparring. Younger bulls will often back off from larger males, but similarly sized bulls will often confront each other. Males use these battles to show their strength, and the bulls often sustain injuries, but rarely fatal ones, during the struggle. The strongest male wins and thus earns the right to mate. As snow blows in and fall shifts into winter, elk will continue their migration south to the National Elk Refuge, where they will make their winter home. Bull Elk Bison also join in on fall migration. While summers are spent in the eastern sagebrush plains of the park, the coming of fall sees bison head south to lower elevations. Less snow makes it easier to reach the grasses that are their main food source. Bison are experts at using their large heads to plow snow off the ground to reach the grass below. While you travel through Grand Teton, look out for the various animals also making their journey through the park. Fall is a time for movement and change, but will soon ease into the quiet of winter. Take in all the changes around you and breathe in the new energy that comes with the arrival of fall. Pronghorn Buck The Science of Color Black Hawthorn Crataegus douglasii During spring and summer, leaves use sunlight to generate food for the plant. Chlorophyll harnesses the sun’s energy to convert carbon dioxide and water into carbohydrates to sustain growth, giving leaves their green color. In fall, the length of daylight and cooling temperatures cause leaves to stop generating food. Chlorophyll breaks down and the green color disappears allowing other pigments to become visible like carotenoids that produce brillant yellow and orange leaves. Some leaves will generate red pigments, anthocyanins, due to excess water and sugars. Temperature and moisture control the intensity and duration of the colors. A wet growing season followed by dry, sunny autumn days with crisp, cool (but not freezing) nights seems to yield the best colors.
