Joyce Kilmer Slickrock Add.

The Joyce Kilmer Slickrock Addition encompasses 1,396 acres of the Unicoi Mountains within the Cherokee National Forest, spanning elevations from 2,411 feet at Stiffknee Top to 2,831 feet at Farr Gap. This terrain channels water through multiple named drainages—Tallasee Creek, First Creek, Goat Creek, and Lowdown Branch—that feed into the Little Tennessee River watershed and ultimately Chilhowee Lake. The steep topography and high precipitation create a landscape where water moves constantly downslope, carving coves and hollows that concentrate moisture and organic matter in ways that shape every forest community below.

The area supports four distinct forest types arranged along elevation and moisture gradients. In the wettest coves, the Acidic Cove Forest (Silverbell-Hemlock Type) dominates, where eastern hemlock (Tsuga canadensis) and yellow birch (Betula alleghaniensis) form a dense canopy that filters light to near darkness. The understory here is sparse, dominated by rhododendron (Rhododendron maximum) and ferns. At mid-elevations on mesic slopes, the Southern Appalachian Northern Hardwood Forest transitions in, with American beech (Fagus grandifolia) and northern red oak (Quercus rubra) creating a more open canopy structure. On drier ridges and south-facing slopes, the Montane Oak-Hickory Forest takes over, with white oak (Quercus alba) and pignut hickory (Carya glabra) as the primary canopy species. The Southern Appalachian Grass Bald occupies the highest exposed ridgelines, where turkeybeard (Xerophyllum asphodeloides) and lanceleaf bluets (Houstonia lanceolata) grow in open herbaceous communities. Within the Cove Hardwood Forest, the white fringeless orchid (Platanthera integrilabia), a federally threatened species, occurs in specific microhabitats where moisture and light conditions align.

The streams and seeps support specialized aquatic and semi-aquatic communities. Brook trout (Salvelinus fontinalis) inhabit the cold, clear headwater branches, where they feed on aquatic invertebrates. The yellowfin madtom (Noturus flavipinnis), a federally endangered catfish, occupies similar cold-water habitat in the larger named streams. In the substrate of these creeks, the federally endangered Anthony's riversnail (Athearnia anthonyi) and the proposed endangered Tennessee pigtoe (Pleuronaia barnesiana) and Tennessee clubshell (Pleurobema oviforme) filter-feed on suspended particles. The dark hemlock coves provide critical roosting habitat for the federally endangered gray bat (Myotis grisescens) and Indiana bat (Myotis sodalis), which emerge at dusk to hunt insects over the streams and forest openings. On the forest floor and in leaf litter, red-cheeked salamanders (Plethodon jordani) and pygmy salamanders (Desmognathus wrighti) move through the moist soil, preying on small invertebrates. American black bears forage across all elevations, feeding on mast in the oak-hickory forests and on vegetation in the coves. The Carolina Northern Flying Squirrel (Glaucomys sabrinus coloratus), an endangered subspecies, glides between hemlock and beech trees in the cove forests at night, feeding on fungi and lichen.

Walking from Lowdown Branch upslope toward Farr Gap, a visitor experiences the landscape as a series of distinct sensory transitions. The creek bottom is cool and dark, with the sound of water constant and the air heavy with moisture and the smell of rich soil. As the trail climbs out of the hemlock cove, the canopy opens incrementally, light increases, and the understory shifts from sparse rhododendron to a more diverse mix of shrubs and herbaceous plants. The air becomes drier and warmer. Continuing upslope through the oak-hickory forest, the forest floor opens further, with more light reaching the ground and a visible carpet of leaf litter. At the ridgeline, the forest thins dramatically, and the grass bald opens to sky—a sudden shift from enclosed forest to exposed herbaceous meadow where wind becomes the dominant sensory element. This vertical compression of forest types, each with its own community of plants and animals, occurs within a few hundred feet of elevation gain, making the area a concentrated expression of Appalachian ecological diversity.

The Cherokee people inhabited this region of the Southern Appalachian Mountains for hundreds of years prior to European contact, establishing settlements and seasonal camps along nearby river valleys such as the Little Tennessee River. Archaeological evidence indicates that various Indigenous groups had occupied the broader region for approximately twelve thousand years. Before the Cherokee established dominance, other groups including the Creek (Muscogee), Yuchi, and Shawnee utilized parts of eastern Tennessee. The Cherokee eventually drove these groups from the immediate area and held sway over the region until their forced removal to Oklahoma in 1838–1839, known as the Trail of Tears.

Beginning in the early 1800s, the area experienced intensive industrial logging. The Babcock Lumber Company, based in Pittsburgh, operated in the Slickrock Creek watershed beginning in 1915, logging approximately two-thirds of the watershed before operations ceased. The company operated a standard gauge railroad to transport timber out of the area. In 1922, construction of the Calderwood Dam on the Little Tennessee River flooded the lower portion of the railroad access. The Gennett Lumber Company owned over twenty thousand acres in the region, including the Little Santeetlah Creek basin. Significant portions of these watersheds, notably Little Santeetlah Creek, escaped logging due to extreme remoteness, rugged terrain, and the eventual bankruptcy of local timber firms, preserving old-growth forest in these areas.

The Cherokee National Forest was officially established on June 14, 1920, through Presidential Proclamation 1568 issued by President Woodrow Wilson. The forest's creation was authorized under the Weeks Act of 1911, which allowed the federal government to purchase private lands to protect the headwaters of navigable streams, and also cited the Forest Reserve Act of 1891 as a source of authority. The proclamation consolidated the Tennessee portions of the Unaka, Cherokee, and Pisgah National Forests into a single administrative unit entirely within Tennessee. The forest is divided into two distinct sections by the Great Smoky Mountains National Park, which was established in the 1930s.

In 1934, the Veterans of Foreign Wars petitioned the federal government to create a memorial for Joyce Kilmer, a poet and journalist killed in World War I. The U.S. Forest Service dedicated 3,800 acres of old-growth forest as the Joyce Kilmer Memorial Forest on July 30, 1936. During the 1930s, the Civilian Conservation Corps worked in the Cherokee National Forest to restore lands damaged by overlogging, constructing fire roads, ranger stations, and recreation facilities including the Tellico Ranger Station Complex.

On December 20, 2018, the Tennessee Wilderness Act was signed into law as part of the Farm Bill, designating nearly twenty thousand acres within the Cherokee National Forest as protected wilderness. This 1,396-acre area, known as the Joyce Kilmer Slickrock Addition, is now protected as an Inventoried Roadless Area under the 2001 Roadless Area Conservation Rule.

Vital Resources Protected

Headwater Protection for Federally Endangered Aquatic Species

The Slickrock Creek and Little Santeetlah Creek drainages originating in this roadless area feed the Little Tennessee River system and maintain some of the highest-quality water in the Southern Appalachians. These cold, chemically stable streams are critical habitat for the federally endangered Anthony's riversnail (Athearnia anthonyi) and the federally threatened yellowfin madtom (Noturus flavipinnis), both of which depend on stable pH (≥5.5) and acid neutralizing capacity to survive. The roadless condition preserves the intact riparian canopy and undisturbed streambed substrates that these species require—disturbance that cannot be reversed once the hydrological and chemical integrity of these headwaters is compromised.

Bat Hibernacula and Foraging Habitat for Four Federally Endangered Species

The cove hardwood and acidic cove forest ecosystems provide critical habitat for four federally endangered bat species: the gray bat (Myotis grisescens), Indiana bat (Myotis sodalis), northern long-eared bat (Myotis septentrionalis), and the proposed endangered tricolored bat (Perimyotis subflavus). These species depend on the structural complexity of mature forest—intact canopy layers, snags, and understory vegetation—for foraging and roosting. The roadless area's unfragmented interior forest maintains the acoustic and thermal conditions these bats require to hunt insects efficiently and survive winter hibernation in nearby caves. Road construction would fragment this habitat into edge-dominated patches where light penetration and wind exposure reduce insect availability and increase predation risk.

Old-Growth Hemlock-Hardwood Structural Complexity and Soil Carbon Storage

The acidic cove forest (silverbell-hemlock type) and montane northern hardwood ecosystems contain old-growth structural elements—large trees, deep leaf litter, and complex canopy layers—that have accumulated over centuries. Although hemlock woolly adelgid has caused significant mortality of eastern hemlock (Tsuga canadensis) throughout the drainage, the remaining old-growth hardwood canopy and the accumulated organic matter in forest soils remain intact. This structural complexity supports shade-dependent species including the near-threatened red-cheeked salamander (Plethodon jordani) and vulnerable small spreading pogonia (Cleistesiopsis bifaria). The deep, undisturbed soil organic layers also store carbon and regulate water infiltration; once excavated or compacted by road construction, these functions cannot be restored on meaningful timescales.

Elevational Gradient Connectivity for Climate-Sensitive Species

The area spans from 2,411 feet (Stiffknee Top) to higher elevations in the Unicoi Mountains, creating a continuous elevational gradient across montane oak-hickory forest, cove hardwood, and southern Appalachian grass bald ecosystems. This unbroken elevation profile allows species to shift their ranges in response to climate change—a critical adaptation as regional temperatures rise. The federally threatened white fringeless orchid (Platanthera integrilabia) and vulnerable three birds orchid (Triphora trianthophoros) depend on this connectivity to track suitable microclimates. Road construction would sever this gradient, isolating populations at higher elevations and preventing upslope migration as lower elevations become unsuitable.

Threats from Road Construction

Sedimentation and Stream Temperature Increase from Canopy Removal and Cut Slopes

Road construction requires removal of forest canopy along the roadbed and excavation of cut slopes into the steep terrain. Exposed mineral soil on cut slopes erodes during rainfall, delivering fine sediment into the drainage network and smothering the clean gravel spawning substrates that the federally threatened yellowfin madtom and native brook trout require for reproduction. Simultaneously, canopy removal along the road corridor increases solar radiation reaching the streams, raising water temperature—a direct threat to cold-water species like Anthony's riversnail, which cannot tolerate the warmer conditions that result. These changes are particularly severe in headwater streams, where even small temperature increases can exceed the thermal tolerance of sensitive species and where sediment loads accumulate with no opportunity for settling.

Habitat Fragmentation and Edge Effects on Forest-Interior Bat Species

Road construction fragments the unfragmented interior forest into smaller patches separated by the road corridor itself and the edge habitat created along both sides of the roadbed. The four federally endangered bat species that forage in this area require continuous, structurally complex forest interior to hunt efficiently; fragmentation reduces the size of available foraging patches and creates edge zones where increased light and wind exposure reduce insect abundance. The road corridor itself becomes a barrier to movement, particularly for the Indiana bat (Myotis sodalis), which navigates using echolocation and avoids open areas. Once fragmented, the habitat cannot be reassembled—the forest will remain divided by the permanent road infrastructure, and the loss of interior conditions will persist indefinitely.

Hydrological Disruption and Acid Neutralizing Capacity Depletion in Chemically Sensitive Streams

Road construction requires fill material and drainage structures (culverts) that alter subsurface water flow and increase the residence time of water in contact with exposed mineral soils. In this region, where acid deposition has already reduced the acid neutralizing capacity (ANC) of streams below optimal thresholds, road-related hydrological changes accelerate cation leaching from soils and increase aluminum mobilization—both of which further lower stream pH and ANC. The federally endangered Anthony's riversnail and federally threatened yellowfin madtom are already living at the edge of their chemical tolerance; additional acidification from road-induced hydrological changes could push these populations below viable densities. Because the underlying cause is regional acid deposition, recovery would require both restoration of stream chemistry (a multi-decade process) and removal of the road—an economically and logistically prohibitive scenario.

Invasive Species Establishment and Spread via Road Disturbance Corridors

Road construction creates a linear corridor of disturbed soil, reduced canopy cover, and increased human access—conditions that favor invasive species establishment and spread. The hemlock woolly adelgid has already devastated eastern hemlock throughout the Slickrock Creek drainage; a road corridor would provide a dispersal pathway for this pest and other invasive species (emerald ash borer, gypsy moth) into currently less-affected portions of the roadless area. The increased fuel loads from dead hemlock already elevate fire risk; invasive species establishment in the road corridor would further alter fire behavior and increase the likelihood of high-intensity fires that damage old-growth soil organic layers and eliminate habitat for shade-dependent species like the red-cheeked salamander and small spreading pogonia. Once established, invasive species cannot be eradicated from a landscape of this size, making prevention through roadlessness the only viable conservation strategy.

The Joyce Kilmer Slickrock Addition encompasses 1,396 acres of mountainous terrain in the Cherokee National Forest, ranging from 1,100 feet along Slickrock Creek to 2,831 feet at Farr Gap. This roadless area protects a network of backcountry trails, cold-water trout streams, and interior forest habitat that would be fragmented and degraded by road construction. Access is limited to foot traffic and pack animals on designated trails; the absence of roads preserves the wilderness character essential to the recreation opportunities described here.

Hiking and Backcountry Travel

Two primary trails provide access to the roadless area's interior. The Stiffknee Trail (106) departs from Big Fat Gap Trailhead and descends steeply 3.1 miles from Farr Gap (2,831 ft) to Little Slickrock Creek, dropping approximately 2,200 feet over rugged, narrow tread. The trail is rated difficult and shows maintenance deficit in sections; hikers should watch for cut logs to stay on route. The Slickrock Creek Trail (TR42) is one of the ten toughest trails in the United States, climbing 3,700 feet over 12.8 miles from the Tapoco Trailhead near Cheoah Dam to Naked Ground. This extreme-difficulty route requires 12 to 13 stream fords that become dangerous during high water. Both trails connect to the broader Benton MacKaye Trail system and link this roadless area to the Citico Creek Wilderness and Nantahala National Forest, forming one of the largest contiguous roadless areas in the Southeast. The Farr Gap Loop combines Stiffknee, Slickrock Creek, Big Stack Gap Branch, and Fodderstack trails for a strenuous 12-mile circuit. No trail blazes mark the way; only junction signs are provided. Bicycles and motorized equipment are prohibited within the designated wilderness portions. The roadless condition preserves the quiet, undisturbed backcountry experience these difficult trails require—road access would fragment the landscape and introduce noise incompatible with wilderness travel.

Fishing

Slickrock Creek, forming the Tennessee-North Carolina border, is the primary fishery. The stream supports wild brown trout descended from 1930s Civilian Conservation Corps stockings; the upper reaches above Lower Falls are managed for wild populations with no modern stocking. Rainbow trout inhabit lower sections, and large brook trout have been documented in the deep pool at Lower Falls. Tallasee Creek supports 12 species including brook, brown, and rainbow trout, bluegill, and channel catfish. Anglers access these streams via steep descents: the Big Fat Gap Trail drops 1,000 feet in 2 miles to reach the creek, rated most difficult. The Slickrock Creek Trail and Stiffknee Trail provide longer approaches. Spring fly fishing is productive during Sulphur, Drake, and Yellow Sally hatches; fall brings spawning brown trout moving upstream from Calderwood Lake. A valid Tennessee or North Carolina fishing license is recognized for the state-line section. The creel limit is 7 trout per day. The roadless condition maintains the cold, undisturbed headwater habitat and intact riparian corridors that support these wild trout populations. Road construction would warm streams, increase sedimentation, and degrade the wilderness fishing experience.

Hunting

Black bear and wild turkey are the primary game species. The area lies within the Tellico River Wildlife Management Area and is adjacent to the Tellico Bear Reserve. Bear seasons typically run late September through December; turkey seasons occur in spring (April–May), governed by Tennessee Wildlife Resources Agency regulations. Wild boar, established in the region since 1912, also inhabit the area. Hunters access the roadless area via Farr Gap and the Stiffknee Trail, with dispersed campsites located along Double Camp Creek and near Farr Gap. Bear Creek Hunt Camp provides a base for hunting operations. A Forest Service order limits group size to 10 people; vehicles and game carts are strictly prohibited within the designated wilderness. The roadless condition preserves the remote, undisturbed habitat and quiet conditions essential to hunting success. Roads would fragment wildlife corridors, increase human disturbance, and degrade the primitive hunting experience.

Birding

The area's montane hardwood and cove forest support interior forest species including Wood Thrush, Scarlet Tanager, Black-throated Green Warbler, Indigo Bunting, and Eastern Towhee. High-elevation specialties include Black-billed Cuckoo, Yellow-bellied Sapsucker, Winter Wren, and Common Raven. Broad-winged Hawks and Bald Eagles are documented in the broader region. Spring migration (mid-April peak) offers the best variety of warblers and other songbirds in breeding plumage. Fall migration concentrates raptors on high ridges. Access via Farr Gap and the Stiffknee Trail provides entry to these elevations. The roadless condition preserves the unfragmented interior forest habitat and quiet conditions that support breeding songbirds and migrating warblers. Road construction would fragment forest interior, increase noise and human disturbance, and degrade critical breeding and migration habitat.
