Mule deer within the Upper Shoshone herd make a number of significant, long-distance migrations west into the core of the Greater Yellowstone Ecosystem. The longest is a 133-mile (214-km) migration that originates at the mouth of the South Fork of the Shoshone River near Buffalo Bill Reservoir and ends at Jenny Lake in Grand Teton National Park. Deer in the Upper Shoshone herd winter in the lower-elevation sagebrush valleys of the South Fork Shoshone River and North Fork of the Shoshone River. Each spring, an estimated 6,700 deer head west into the high-elevation, mountainous country of the Absaroka Range and then into Yellowstone National Park or Grand Teton National Park. These challenging journeys, an average...
Mule deer within the Clarks Fork herd make a number of significant westward long-distance migrations. These migrations originate north of Cody, near Heart Mountain and along the foothills of Absaroka Front. There, deer winter in the lower elevation sagebrush valleys, and in spring an estimated 2,700 deer head west into the high elevation mountain valleys of the Absaroka Range and Yellowstone National Park. This herd summers along the Lamar River, Cache Creek, and the Clarks Fork of the Yellowstone. The longest migration is 68 miles and ends just north of Yellowstone Lake along the Yellowstone River in the Hayden Valley. These challenging journeys, an average of 38 miles long, cross rugged terrain and steep mountain...

The Carter Mountain pronghorn herd contains approximately 7,000 animals—half which migrate 10–60 mi (16–97 km) west from common winter ranges in the Bighorn Basin to summer ranges near the Absaroka Range (fig. 29). During this migration, pronghorn must cross U.S. Highway 14 and Wyoming Highway 120. Most pronghorn summer in ranges west of Wyoming Highway 120 along the Greybull River, but some individuals summer in the South Fork Shoshone River drainage. A segment of the population gains nearly 6,000 ft (1,829 m) in elevation to summer on the high plateaus of the Absaroka Range and upper Greybull River and spend the summer months at 10,000–11,000 ft (3,048–3,353 m) above sea level in alpine meadows they share with...

Ungulate Migrations of the Western United States, Volume 4
This is the data archive for the publication Ungulate Migrations of the Western United States, Volume 4 and includes the collection of GIS map files that are mapped and described in the report. These map files are meant to provide a common spatial representation of the mapped migrations and seasonal ranges. This data release provides the means for ungulate migrations to be mapped and planned for across a wide variety of landscapes where they occur. Due to data sharing constraints of participating agencies, not all the files that underlie the mapped migrations included in the report have been released. Data in this archive can be downloaded two ways. To download by individual herd/range, clicking on child item pages...
Mule deer within the Owl Creek/Meeteetse herd make a number of medium- to long-distance migrations west into the Shoshone National Forest. These migrations originate on the sagebrush grasslands just southwest and west of Meeteetse, Wyoming, where this population winters. In spring, an estimated 4,100 deer leave these foothills and travel into the rugged Absaroka mountain range. These journeys, across challenging natural terrain, range an average of 27 miles and include navigating fast moving rivers, such as the Greybull River, and over high mountains passes like Bear Creek and East Fork Pass—the highest at 12,230 feet in elevation. The longest migration is 70 miles to the Dunoir Valley northwest of Dubois. Although...
