Why Shoshone National Forest stands out
Shoshone National Forest is best known as America's first national forest, a distinction it has held since 1891 and which gives it foundational significance in the history of U.S. conservation policy. The forest is also known for encompassing some of the most rugged and ecologically intact mountain terrain in the Greater Yellowstone Ecosystem, from the volcanic Absaroka Range to the ancient Precambrian granites of the Wind River and Beartooth Mountains. Its wildlife profile is another defining feature, with thriving populations of grizzly bears, gray wolves, bighorn sheep, elk, and mule deer, all sharing a landscape of designated wilderness, glacial cirques, alpine lakes, and the headwaters of major Rocky Mountain rivers. The forest's proximity to Yellowstone National Park and its dramatic scenic byways, especially the Beartooth Highway, further reinforce its identity as one of the crown-jewel landscapes of the American West.
Shoshone National Forest history and protected-area timeline
The human history of Shoshone National Forest extends back at least 10,000 years, when paleoindian peoples inhabited the caves and river valleys of what is now northwestern Wyoming. Archaeological sites such as Mummy Cave, rediscovered in 1957 and subsequently excavated through the 1960s, document continuous occupation from around 7280 BC through the late pre-contact period and reveal a finely preserved paleoindian cultural assemblage placed on the National Register of Historic Places in 1981. In more recent centuries, the forest was home to Shoshone, Lakota, Crow, and Northern Cheyenne peoples, who used the high country for hunting, shelter, and spiritual practice. In the 1840s and 1860s, Chief Washakie of the Eastern Shoshone negotiated with the U.S. government, ultimately resulting in the establishment of the Wind River Indian Reservation, which still borders the forest today.
The first European exploration of the area occurred in the early nineteenth century by mountain men including John Colter, Jim Bridger, and Manuel Lisa, who traversed the Absaroka Range, Jackson Hole, and the headwaters of major rivers. Later scientific and military expeditions, notably the Raynolds Expedition of 1860 led by Captain William F. Raynolds and guided by Jim Bridger, completed much of the geographic understanding of the region. Ferdinand V. Hayden, geologist and naturalist on that expedition, returned in 1871 and helped build the public case that the Greater Yellowstone country deserved federal protection.
The defining moment in the forest's institutional history came in 1891 with the Forest Reserve Act, which authorized the President to set aside public land as forest reserves. President Benjamin Harrison immediately designated the Yellowstone Timberland Reserve, the nation's first. In 1902 President Theodore Roosevelt expanded the reserve and divided it into four units, of which Shoshone was the largest. With the creation of the U.S. Forest Service in 1905, the reserve was redesignated as a national forest, and its present title was formally adopted in 1945. The surviving Wapiti Ranger Station, built in 1903, is the oldest ranger station in any U.S. national forest and is recognized as a National Historic Landmark. Following World War II, visitation rose sharply with improved road access, and in the mid-twentieth century Civilian Conservation Corps camps built during the Great Depression left a lasting legacy of roads, trails, and campgrounds throughout the forest.
Shoshone National Forest landscape and geographic character
Shoshone National Forest contains some of the most dramatic and varied mountain scenery in the Greater Yellowstone Ecosystem, with elevations ranging from roughly 4,600 feet near Cody to 13,804 feet at Gannett Peak, the highest point in Wyoming. The forest encompasses three geologically distinct mountain ranges, each contributing a different character to the overall landscape. In the northern and central portions of the forest, the Absaroka Range rises in volcanic ridges of andesite and breccia laid down during Eocene volcanic activity around 50 million years ago, with Francs Peak, at 13,158 feet, marking the highest summit. Major passes through the Absarokas include Sylvan Pass, the route to Yellowstone's east entrance, and Togwotee Pass, the gateway to Jackson Hole and Grand Teton National Park.
At the far north of the forest, a small portion of the Beartooth Mountains rises in windswept plateaus and sheer cliffs of ancient Precambrian granite. Uplifted during the Laramide orogeny around 70 million years ago, the Beartooths are among the oldest exposed rocks in North America and host Beartooth Lake, dramatic cliff-walled glacial valleys, and some of the most popular alpine scenery in Wyoming. The Beartooth Highway, an All-American Road National Scenic Byway, crosses 10,974-foot Beartooth Pass and links the forest with Yellowstone's northeast entrance.
The southern section of the forest is dominated by the Wind River Range, a vast spine of Precambrian granite containing eight summits above 13,500 feet and 119 peaks over 12,000 feet. The Cirque of the Towers, located in the Popo Agie Wilderness, is one of the most famous alpine climbing areas in the country, surrounded by sheer granite walls and more than 200 climbing routes. The forest is also home to more than 500 lakes and about 1,000 miles of streams and rivers, including the Clarks Fork of the Yellowstone, which is federally designated as a Wild and Scenic River for 22 miles through a dramatic canyon walled by cliffs rising up to 2,000 feet.
Shoshone National Forest ecosystems, habitats, and plant life
Because the forest stretches across more than 9,000 vertical feet, it contains an unusually wide spectrum of Rocky Mountain ecosystems within a single protected area. Lower-elevation sites near Cody support sagebrush steppe and grassland communities, while mid-elevation forests are dominated by lodgepole pine, Rocky Mountain juniper, and quaking aspen. Higher montane and subalpine forests give way to stands of subalpine fir, Engelmann spruce, whitebark pine, and limber pine, and these in turn yield to alpine tundra and ultimately to rock, ice, and barren alpine terrain, which together account for roughly a quarter of the forest's total acreage. Along lower-elevation streams, cottonwoods and willows create distinct riparian corridors. Endemic plant species such as the shoshonea, fremont bladderpod, north fork Easter daisy, and a whitlow grass contribute to the region's botanical distinctiveness, while invasive exotics such as Canada thistle, spotted knapweed, and leafy spurge pose ongoing management challenges.
The forest lies within the Greater Yellowstone Ecosystem, which supports approximately 1,700 documented plant species. The complex elevation gradient, combined with the wide variation in moisture availability, creates a landscape of striking ecological transitions, from dry sage flats to high cirques holding snow well into summer. Tree distribution is strongly governed by water availability, with denser forests on higher slopes where longer-lasting snowpack keeps soils moist into the growing season. Mountain pine beetle and related bark beetle outbreaks have impacted more than a million acres of timberland, and have triggered intensive forest management efforts including controlled burns, salvage harvest, and targeted spraying to reduce wildfire risk and recover dead wood.
Shoshone National Forest contains 16 named and more than 140 unnamed glaciers, all located in the Wind River Range, making it the most glacier-rich national forest in the Rocky Mountains. Forty-four of these glaciers cluster in the Fitzpatrick Wilderness around the range's highest peaks. Like mid-latitude glaciers worldwide, they have been retreating significantly since the end of the Little Ice Age, with substantial volume loss documented across the twentieth and early twenty-first centuries. Gannett Glacier, on the northeast flank of Gannett Peak, is the largest single glacier in the U.S. Rocky Mountains.
Where the climate is generally arid, with most precipitation falling in winter and spring, higher elevations receive dramatically more moisture and snow, sustaining the glaciers and the cold-water habitats that many native fish species depend on.
Shoshone National Forest wildlife and species highlights
Shoshone National Forest harbors one of the most complete native wildlife communities in the contiguous United States. All 70 mammal species historically present in the region still occur there, and at least 335 wildlife species overall have been documented. The forest supports roughly 125 grizzly bears within an estimated Greater Yellowstone population of about 700, making it one of the last major strongholds of the species in the lower 48. American black bears are also present and managed through cooperative programs with neighboring national forests and Yellowstone. Management of human-bear conflict includes trapping, ear-tagging, and relocation, and in serious cases, removal of chronically nuisance animals, along with food storage requirements for visitors in both frontcountry and backcountry areas.
Gray wolves, originally absent from the region after aggressive early eradication programs, were reintroduced in nearby Yellowstone in the mid-1990s and have since established permanent packs in Shoshone National Forest. By 2012, about a dozen packs and roughly 70 wolves were documented in the forest, and managed hunting seasons were later introduced. Other large carnivores include cougars, which are nocturnal and rarely seen, and rare wolverines, which are usually documented only by tracks. Coyotes, bobcats, weasels, martens, ferrets, and badgers round out the carnivore community. Omnivores such as raccoons and skunks are common, along with smaller mammals like porcupines and American pikas.
Ungulates are abundant. Elk number more than 20,000 and mule deer about 40,000, while bison and pronghorn antelope maintain sustainable populations as well. Bighorn sheep are particularly associated with the forest's rocky terrain; the herd that winters near Dubois is one of the largest in the lower 48 states, though disease transmission from domestic sheep and goats has reduced numbers since the 1990s. About 5,000 bighorn sheep live across the forest, and a small, stable population of roughly 200 mountain goats inhabits the northernmost portions. Moose, though declining in recent decades, are still found near lowland waterways, with around 739 estimated in 2006. Beavers are especially valued for their role in maintaining wetland and riparian habitat that benefits moose, waterfowl, amphibians, and other species.
The forest supports approximately 300 species of birds, including bald eagles, peregrine falcons, Swainson's hawks, and prairie falcons. Waterfowl such as western grebes, northern pintails, great blue herons, and Barrow's goldeneyes have stable populations along forest rivers and lakes, and rare trumpeter swans are sometimes observed. Sage-country upland species like pheasants, ruffed grouse, and wild turkeys are common, while sensitive species such as harlequin ducks and northern goshawks receive targeted habitat protection. Fish communities include rainbow, brook, brown, and Yellowstone cutthroat trout, with the Shoshone River being a particularly important stronghold of the native Yellowstone cutthroat. Reptiles include prairie rattlesnakes at lower elevations and various lizards and turtles, while amphibians such as the Columbia spotted frog and boreal toad are considered species of concern due to disease and habitat change.
Shoshone National Forest conservation status and protection priorities
Shoshone National Forest is a landmark in the history of American conservation, beginning with the Forest Reserve Act of 1891, which fundamentally changed the federal government's relationship to public land by allowing the President to set aside forest reserves rather than disposing of them through private transfer. The forest is a key component of the Greater Yellowstone Ecosystem, one of the largest nearly intact natural ecosystems in the temperate world, and the protection of its wilderness, rivers, wildlife, and headwaters has been a defining element of regional conservation policy for more than a century.
Roughly 56 percent of the forest is officially designated wilderness within the meaning of the Wilderness Act of 1964, providing the highest level of land protection available under U.S. law. Within these wilderness areas, all forms of mechanized transport, road construction, building, logging, and mineral extraction are prohibited, allowing ecosystems to function without major human alteration. The Clarks Fork of the Yellowstone is federally designated as a Wild and Scenic River for 22 miles through the forest. The forest's extensive roadless and wilderness lands make it a critical refuge for wide-ranging species such as grizzly bears, gray wolves, and wolverines, and the entire forest is considered critical habitat for Canada lynx recovery under the Endangered Species Act.
Conservation management within the forest continues to confront several large-scale pressures. Mountain pine beetles and related bark beetle outbreaks have killed trees across more than a million acres, accelerating fuel accumulation and increasing wildfire risk. Forest managers respond with controlled burns, fuel reduction projects, salvage logging, and targeted treatment of high-value stands. Invasive species also threaten the forest's native plant communities, and managers maintain a precautionary aquatic invasive species program focused on zebra mussels, quagga mussels, and the New Zealand mud snail, which have already been detected nearby. Finally, the retreat of the forest's glaciers is reducing late-summer cold-water runoff, with downstream consequences for native trout and other cold-water species, and illustrates how climate change is now a central driver of long-term conservation planning in the region.
Shoshone National Forest cultural meaning and human context
Shoshone National Forest takes its name from the Shoshone people and lies adjacent to the Wind River Indian Reservation, home to the Eastern Shoshone and Northern Arapaho. The forest's indigenous heritage extends back at least 10,000 years, as documented by archaeological sites such as Mummy Cave, and the dramatic mountain landscapes of the Absaroka and Wind River ranges were used by the Shoshone, Lakota, Crow, and Northern Cheyenne for hunting, shelter, and spiritual practice, including vision quests in the high country. Chief Washakie's mid-nineteenth-century negotiations with the U.S. government led to the establishment of the Wind River Indian Reservation, which today still borders the forest to the east.
The forest also sits at the heart of nineteenth-century American westward movement. The Oregon Trail, the South Pass route used by covered wagon migrants heading west, passes just south of the forest and gives a cultural context to the rugged landscape the pioneers encountered. The Chief Joseph Scenic Byway, running through the forest, follows the trail along which the Nez Perce and their leader Chief Joseph attempted to flee the U.S. Cavalry in 1877. Fort Washakie, built on the reservation lands east of the forest, was a U.S. Cavalry post staffed in part by African-American Buffalo Soldiers, including the second African-American graduate of West Point. The forest's natural setting also made it a cultural touchstone in modern media, serving as the setting for the 2016 video game Firewatch.
Top sights and standout views in Shoshone National Forest
Shoshone National Forest stands out as the first federally protected national forest in the United States, set aside by President Benjamin Harrison in 1891 and still recognized as a foundational landmark of American conservation. Its landscape sweeps from the sagebrush lowlands near Cody to the glacier-clad summit of Gannett Peak, the highest point in Wyoming, encompassing the ancient Precambrian granites of the Wind River and Beartooth ranges and the volcanic Absaroka Range in a single contiguous protected area.
With more than half of its land designated wilderness, the forest preserves some of the most ecologically intact habitat in the Greater Yellowstone Ecosystem, supporting thriving populations of grizzly bears, gray wolves, elk, mule deer, bighorn sheep, and mountain goats. Together with the Beartooth Highway, the Chief Joseph Scenic Byway, the Buffalo Bill Cody Scenic Byway, and the Wyoming Centennial Scenic Byway, the forest offers access to Yellowstone, Grand Teton, and the heart of the American Rocky Mountain West.
Best time to visit Shoshone National Forest
Because the forest covers such a wide range of elevations, the best time to visit depends largely on the type of experience desired. Summer, from roughly June through early September, is the most versatile season: trails in the subalpine and alpine zones are largely free of snow, wildflowers including endemic species such as shoshonea and the fremont bladderpod are at their peak, and the forest's many rivers, lakes, and campgrounds are most accessible. Late summer, particularly August and September, brings the warmest and driest conditions at lower elevations, but it is also the period with the highest natural wildfire activity, since lightning is the dominant ignition source across the forest.
Winter transforms the forest into a different kind of destination, with extensive snowmobile trails and cross-country skiing routes opening in the Togwotee Pass area, where snowpack regularly reaches 6 to 10 feet at higher elevations. Spring and autumn tend to be quieter seasons marked by strong temperature swings, lingering snow at high elevations, and rapidly changing conditions. Across all seasons, large daily temperature variations are the rule, and visitors should expect cool to cold nights even during summer, especially at higher altitudes.
