Nugent Park - Hams Fork Ridge

Nugent Park – Hams Fork Ridge covers 21,241 acres of montane mountain country on the Bridger-Teton National Forest in western Wyoming. The area takes in the Tunp Range, the open expanse of Nugent Park, the long crest of Hams Fork Ridge, and the basin called Poison Hollow. Drainage is significant. The West Fork Hams Fork rises here, joined by East Fork Hams Fork, Elk Creek, Kelley Creek, Chappel Creek and North Chappel Creek, Shingle Mill Creek, Burke Creek, Basin Creek, Hawkins Creek, Allen Creek, Coal Creek, Sawmill Creek, Spring Creek, Rock Creek, and Trail Creek. Big Spring contributes steady cold flow to the headwater system. These streams gather across the ridge and feed the Hams Fork drainage downslope.

Forest communities sort themselves by elevation and moisture. On the high ground, Rocky Mountain Dry Subalpine Spruce-Fir Forest and Rocky Mountain Wet Subalpine Spruce-Fir Forest hold subalpine fir (Abies lasiocarpa) above carpets of creeping Oregon-grape (Berberis repens). Rocky Mountain Lodgepole Pine Forest fills the middle slopes, with Central Rockies Douglas-fir Forest holding the warmer aspects in stands of Douglas-fir (Pseudotsuga menziesii). Quaking aspen (Populus tremuloides) shoulders into the disturbance-shaped Rocky Mountain Aspen Forest and the Intermountain Aspen and Conifer Forest, its understory thick with red raspberry (Rubus idaeus), thimbleberry (Rubus parviflorus), and choke cherry (Prunus virginiana). Higher and drier, Rocky Mountain Limber and Bristlecone Pine Woodland clings to wind-exposed ribs. Rocky Mountain Subalpine Meadow opens at saddles and parks, while Rocky Mountain Subalpine Streamside Woodland and Streamside Shrubland trace the creeks. Lower benches carry Intermountain Mountain Sagebrush Steppe and Great Basin Big Sagebrush Steppe, breaking against Northern Rockies Foothill Shrubland and Foothill and Valley Grassland.

Wildlife uses the area in layered fashion. Cougar (Puma concolor) and coyote (Canis latrans) work the timbered slopes and aspen edges where dusky grouse (Dendragapus obscurus) and ruffed grouse (Bonasa umbellus) feed. American black bear (Ursus americanus) browse the berry shrubs in summer and clear-cut openings. Beaver (Castor canadensis) shape the streamside woodlands along the smaller forks. Golden eagle (Aquila chrysaetos) hunt across the open parks; broad-tailed hummingbird (Selasphorus platycercus) and rufous hummingbird (Selasphorus rufus) drink at greater red Indian-paintbrush (Castilleja miniata) and western Jacob's-ladder (Polemonium occidentale) in the meadows. Canada jay (Perisoreus canadensis) and Cassin's finch (Haemorhous cassinii) hold the conifer canopy; white-crowned sparrow (Zonotrichia leucophrys) sings from the willow margins along Spring Creek and Big Spring. Western toad (Anaxyrus boreas) and terrestrial gartersnake (Thamnophis elegans) thread the wet meadows. Portions of this area fall within the potential range of several federally listed species; see the Conservation section for details.

A walker on Hams Fork Ridge moves from sagebrush-steppe and shrubby foothill into aspen groves shot through with light, then into the quieter shade of lodgepole and spruce-fir. Crossing into Nugent Park, the canopy opens to a long subalpine meadow where streams meet on a single bench. The sound shifts at each drainage — Elk Creek and Chappel Creek run fast over stone, while Big Spring's outflow is steady and cold. From the ridge, the basin of Poison Hollow drops away through dark conifer and silver-leafed aspen.

Nugent Park – Hams Fork Ridge is a 21,241-acre Inventoried Roadless Area within the Bridger-Teton National Forest in Lincoln County, Wyoming, administered by the Kemmerer Ranger District in the USFS Intermountain Region and protected under the 2001 Roadless Area Conservation Rule.

Human use of the western Wyoming mountains is deep. "Human groups have occupied the mountains of western Wyoming, including the area now known as the Bridger-Teton National Forest, for the last 10,000 years" [1]. Shoshone peoples in particular held the surrounding ranges for thousands of years: "Shoshones have lived in western Wyoming and the Wind River Mountains for at least 3500 years perhaps even 8,000 years ago" [2]. From 1825 to 1840, "all of the Fur Trade Rendezvous... were held in Eastern Shoshone country" [2], drawing trappers across the Green River drainage that flanks the area today.

Anglo-American place names on the ridge mirror that fur-trade era. "The Hoback River, Fontenelle and LaBarge Creeks, Smiths Fork, Hams Fork, and Greys River were all named after early trappers" [1]. Emigrant travel reshaped the region after "In 1857, Engineer Frederick W. Lander surveyed a new route across the Green River Basin and into the mountains of the Wyoming and Salt River Ranges" [1]; "The Lander Cut-off was the first federally funded road project west of the Mississippi" [1].

Industry followed the rails. "The Oregon Short Line railroad was built through Kemmerer in 1881 as a means to access the rich coal mines in the area" [1]. Coal and timber became the dominant economy at the foot of the ridge: "The City of Kemmerer was a town that was organized in 1897, incorporated in 1899, by Patrick Quealy" [3], and "Kemmerer... was founded as a coal town by Patrick Quealy and Mahlon Kemmerer" [4]. The Hams Fork drainage itself supplied the mines. "The Hams Fork area was also the scene of early tie hack operations, but also in the production of mine props for the coal mines in the Kemmerer area" [1]. "The Forest Service reported, in 1914, that evidence of old tie cuttings were visible and that the Hams Fork River was used to float the ties down stream" [1]. The hazards of that economy were real: an explosion at Frontier and Kemmerer on August 14, 1923 killed ninety-nine miners [4].

Federal protection arrived in stages. "On March 30th, 1891, President Benjamin Harrison set aside the Yellowstone Park Timber Land Reserve" [1], the regional precursor. "In 1908 President Roosevelt abolished the Yellowstone National Forest with its separate divisions and created the Teton, Wyoming (now Bridger), Absaroka and Beartooth (now Custer), Shoshone, Bonneville (now Caribou), and Targhee National Forests" [1]. Woodrow Wilson's "Proclamation 1337—Enlarging Area of the Bridger National Forest, Wyoming" took effect July 1, 1916 [5]. "The Wyoming National Forest was renamed the Bridger National Forest in 1941" [1], and "In 1973 the Bridger and Teton National Forests were combined to form a single forest" [1]. The Hams Fork Ridge country today carries that layered history into its present federal management.

Nugent Park – Hams Fork Ridge encompasses 21,241 acres of montane terrain in the Tunp Range of the Bridger-Teton National Forest, with the West Fork Hams Fork rising within its boundaries alongside Big Spring, East Fork Hams Fork, Chappel Creek, Elk Creek, and more than a dozen other named tributaries. Its roadless condition holds together a continuous gradient from sagebrush steppe through aspen and lodgepole into subalpine spruce-fir, with no permanent road network interrupting either the watershed or the elevational mosaic.

Vital Resources Protected

• Cold Headwater Stream Integrity: The West Fork Hams Fork headwaters and the cluster of springs and small tributaries — Big Spring, Spring Creek, Sawmill Creek, Shingle Mill Creek, Trail Creek, and the East and North forks of Chappel Creek — flow through undisturbed Rocky Mountain Subalpine Streamside Woodland and Streamside Shrubland. Roadless terrain keeps cut slopes, culverts, and ditch lines off these unconfined channels, preserving the cold, sediment-poor flow and stable streambanks that downstream aquatic communities depend on.

• Subalpine Ecosystem Integrity: The area protects intact Rocky Mountain Dry and Wet Subalpine Spruce-Fir Forest, Rocky Mountain Subalpine Meadow, Northern Rockies Subalpine Grassland, and Rocky Mountain Limber and Bristlecone Pine Woodland on the high ground around Nugent Park and Hams Fork Ridge. With no roads to break stand structure or open canopy on wind-exposed ribs, these communities continue to function as climate refugia for cold-adapted species and as the seed source for slow-growing limber and bristlecone pine.

• Elevational Gradient Connectivity: Sagebrush steppe — Intermountain Mountain Sagebrush Steppe and Great Basin Big Sagebrush Steppe — covers the lower benches and rises continuously into aspen forest, Douglas-fir forest, lodgepole, and subalpine fir. Roadless condition preserves this uninterrupted vertical band of habitat. Wide-ranging mammals can shift up or down the gradient with the seasons without crossing road corridors that would otherwise concentrate mortality and act as a behavioral barrier.

Potential Effects of Road Construction

• Sedimentation of Headwater Streams: Road construction on the steep timbered slopes above the West Fork Hams Fork and its tributaries cuts into unstable soils and exposes mineral subgrade. The resulting chronic surface erosion and culvert undercutting deliver fine sediment into Big Spring, Chappel Creek, Elk Creek, and the East Fork Hams Fork, smothering spawning substrate and reducing the cold, oligotrophic conditions on which downstream populations rely. Once a road prism is cut into these slopes, chronic sediment input continues for decades regardless of decommissioning.

• Fragmentation of the Sagebrush–Subalpine Gradient: Linear road corridors through Mountain Sagebrush Steppe and lodgepole forest fracture the continuous elevational habitat that allows ungulates and forest carnivores to move between winter and summer range. Roads concentrate human disturbance, increase animal-vehicle mortality, and create persistent edge effects in forest interior. These behavioral and demographic changes outlast the road surface itself.

• Invasive Species along Disturbed Corridors: Construction-disturbed ground in sagebrush steppe and foothill grassland is the primary entry point for cheatgrass, knapweed, and other annual exotics. Once established along a road, invasive cover spreads outward into adjacent Intermountain Aspen and Conifer Forest and Northern Rockies Foothill Shrubland, altering fire regimes, displacing native understory, and reducing the carrying capacity of the system for both forage and pollinators. Reversal requires sustained treatment with uncertain success.

Nugent Park – Hams Fork Ridge covers 21,241 acres of montane country in the Tunp Range of the Bridger-Teton National Forest, with access from the Hams Fork Trailhead and overnight base at the Hams Fork Campground. The area is laced by four documented trails that climb from the trailhead into the headwater country around Nugent Park, Hams Fork Ridge, and Poison Hollow. Travel is overwhelmingly non-motorized backcountry use, with the trail network well-suited to long, quiet day trips and multi-day loops.

The four verified routes form a connected system. Hams Fork Ridge (1SM10151) runs 7.9 miles along the crest, giving open sightlines across the Tunp Range and the West Fork Hams Fork drainage. The Switchbacks (1SM062) covers 8.7 miles of climbing trail between the lower forested benches and the high country. Big Park Loop (1SM10066) is the longest single route in the system at 16.2 miles, circling through Nugent Park and the connecting subalpine meadows. Nugent/Dry Fork (1SM10069) traces 14.6 miles between the high open park country and the Dry Fork drainage. All four trails are documented for snow-surface winter travel, making this area a backcountry destination for ski touring and snowshoeing as well as snow-free summer hiking. Riders, packers, and hikers all use the same corridors in the warm months.

Big-game and upland hunting are central uses of the area. The continuous belt of aspen, lodgepole pine, Douglas-fir, and subalpine fir, broken by sagebrush steppe at lower elevations and open subalpine meadow at the parks, holds American black bear and mountain lion in the timber and edge cover. Dusky grouse and ruffed grouse occupy the aspen and conifer-edge habitats where the canopy breaks. The roadless backcountry is the kind of ground hunters walk into from the Hams Fork Trailhead and stay in for several days. Wyoming Game and Fish hunting regulations and area-specific seasons apply.

The streams within the area — the West Fork Hams Fork headwaters, East Fork Hams Fork, Chappel Creek, Elk Creek, Kelley Creek, Sawmill Creek, Spring Creek, and the cold outflow of Big Spring — are small, high-gradient headwater channels typical of subalpine streamside habitat. Anglers fishing these waters work the small pools and runs that headwater country provides, accessed on foot from the Hams Fork Trailhead and the connecting trails. Wyoming Game and Fish fishing regulations apply.

Birding and wildlife viewing reward attention to habitat. Canada jay and white-crowned sparrow are part of the subalpine forest and meadow-edge community along the higher trails; bald eagle range over the larger drainages and open ridges. American beaver work the streamside woodlands along smaller forks of the Hams Fork system, leaving sign easy to read where the trails cross drainages. Western toad and western terrestrial garter snake live in the wet meadows and damp streamside ground. Photographers find consistent subjects in the aspen stands at autumn turn, the open subalpine meadows of Nugent Park, and the long ridgeline views from Hams Fork Ridge.

Every one of these uses depends on the area's roadless condition. The four trails draw their value from the absence of competing motorized corridors, which keeps wildlife distribution natural and the trail experience quiet. Headwater stream fishing requires the low sediment and stable bank conditions that only intact forested watersheds produce. Hunting success on bear and grouse depends on unfragmented forest cover and the elevational habitat mosaic that allows animals to move with the seasons. Without roads cutting the slopes between Nugent Park, Hams Fork Ridge, and the Dry Fork country, the entire backcountry recreation system functions as a single connected unit reachable only on foot, horse, or ski from the Hams Fork Trailhead.
