Mcclellan Mountain

McClellan Mountain Roadless Area encompasses 21,213 acres across the Malheur National Forest in eastern Oregon, spanning elevations from 5,741 feet at Packsaddle Gap to 7,365 feet at Fields Peak. The landscape is defined by a series of prominent ridges—McClellan Mountain, Riley Mountain, and Moon Mountain—that channel water into five primary drainages: Riley Creek, McClellan Creek, Wickiup Creek, Buck Cabin Creek, and Moon Creek. These headwater streams originate on the higher slopes and flow through steep-sided canyons, including Packsaddle Canyon, creating a network of cold-water corridors that drain the area's moderate hydrologic system.

Forest composition shifts dramatically with elevation and aspect. Lower and drier slopes support Ponderosa Pine Forest and Woodland, where western ponderosa pine (Pinus ponderosa) dominates open stands with an understory of curlleaf mountain mahogany (Cercocarpus ledifolius), pinemat manzanita (Arctostaphylos nevadensis), and geyer's sedge (Carex geyeri). Mid-elevation north-facing slopes transition to Douglas-fir / Western Larch Forest, where western larch (Larix occidentalis) and grand fir (Abies grandis) create denser canopy conditions. Higher elevations and moist coves support Grand Fir / White Fir Mixed Conifer Forest. At the highest elevations, subalpine fir and alpine sagebrush shrubland take hold, where the federally threatened whitebark pine (Pinus albicaulis) persists alongside snowbrush ceanothus (Ceanothus velutinus). Western juniper / sagebrush woodland occupies drier ridgelines and south-facing slopes. The vulnerable mountain lady's-slipper (Cypripedium montanum) occurs in moist forest understories, while peck's paintbrush (Castilleja peckiana) and colonial luina (Luina serpentina) inhabit open, rocky areas.

The area supports a full complement of montane predators and prey species. The federally endangered gray wolf (Canis lupus) hunts mule deer (Odocoileus hemionus) and Rocky Mountain elk (Cervus canadensis nelsoni) across the forested ridges and valleys. Wolverine (Gulo gulo) range across high-elevation terrain. In the cold headwater streams, the federally threatened bull trout (Salvelinus confluentus) and rainbow trout (Oncorhynchus mykiss) occupy different thermal niches, with bull trout preferring the coldest reaches. The white-headed woodpecker forages on ponderosa pine bark for insects in the lower forest zones. Mountain quail move through shrubland and open forest understory. American beaver (Castor canadensis) engineer riparian habitat in the creek corridors. Pollinator communities include the proposed endangered suckley's cuckoo bumble bee (Bombus suckleyi) and the proposed threatened monarch butterfly (Danaus plexippus), both dependent on flowering plants across elevation zones. Columbia spotted frog (Rana luteiventris) occupies shallow pools and seepage areas in the drainage systems.

Traveling through McClellan Mountain, the landscape reveals itself in distinct transitions. A hiker ascending from Packsaddle Gap enters open ponderosa pine woodland where sunlight reaches the forest floor and the understory is sparse and dry. As elevation increases and aspect shifts northward, the forest closes—grand fir and western larch create shade, and the ground becomes carpeted with deeper duff and shade-tolerant plants. Crossing a ridge into a north-facing cove, the air cools noticeably and the canopy darkens further. The sound of water becomes audible as you approach one of the named creeks—Riley, McClellan, or Moon—where the forest opens slightly at the riparian edge and the stream's cold flow is visible through the trees. Higher still, approaching Fields Peak or McClellan Mountain, the forest thins again as elevation and exposure increase, giving way to subalpine conditions where whitebark pine and low shrubs dominate the windswept ridgeline. The sensory experience is one of continuous ecological transition, where elevation and aspect drive visible changes in forest structure, understory composition, and the presence of water across the landscape.

Indigenous peoples of the Columbia Plateau region utilized the Blue Mountains and adjacent high country as part of a seasonal round, moving from lowland winter villages to highland areas for summer and fall hunting and gathering. The Cayuse, a tribe of the Confederated Tribes of the Umatilla Indian Reservation, specifically hunted elk, deer, and mountain sheep in the upper tributary valleys and Blue Mountains. Northern Paiute bands, including those who became the Burns Paiute Tribe, gathered roots, huckleberries, and medicinal plants in the high-elevation terrain. The Wasco and Warm Springs tribes of the Confederated Tribes of Warm Springs also utilized portions of this region. The Treaty of Walla Walla in 1855 reserved hunting and gathering rights for the Confederated Tribes of the Umatilla Indian Reservation on unclaimed lands in the Blue Mountains. The Malheur Indian Reservation, established in 1872 for the Northern Paiute across 1.8 million acres, was discontinued in 1879 following the Bannock War of 1878, after which many Paiute were forcibly removed from the region.

The Malheur National Forest was established by Executive Order 814, signed by President Theodore Roosevelt, on June 13, 1908, with an effective date of July 1, 1908. In 1911, portions of the Umatilla National Forest were transferred to the Malheur National Forest, expanding its holdings.

Large-scale timber extraction began in the late 1920s following major Forest Service timber sales. The Fred Herrick Lumber Company initiated railroad construction in 1924—the Malheur Railroad, a predecessor to the Oregon and Northwestern (O&NW)—to transport timber from the Bear Creek valley to processing facilities. In 1927, the Herrick company lost its substantial Forest Service timber contract due to financial failure and inability to complete required infrastructure. The Edward Hines Lumber Company acquired the timber contracts and became the dominant industrial operator after 1928, establishing Hines, Oregon, a company town southwest of Burns that served as headquarters for regional logging operations. Industrial railroad activity continued until 1984, when the O&NW ceased operations due to flooding of Malheur Lake and declining profitability; the line was officially abandoned in 1990.

In 1954, the Malheur National Forest underwent administrative reorganization of land management divisions. McClellan Mountain was identified as a roadless area during the RARE (Roadless Area Review and Evaluation) process, with its inventoried size increased during RARE II. The area is now protected under the 2001 Roadless Area Conservation Rule.

Vital Resources Protected

Cold-Water Spawning and Rearing Habitat for Bull Trout

The headwaters of Riley Creek, McClellan Creek, Wickiup Creek, Buck Cabin Creek, and Moon Creek originate within this roadless area and feed the Upper John Day River basin. Bull trout (Salvelinus confluentus), a federally threatened species, depend on these cold, clean tributaries for spawning and juvenile rearing. The roadless condition maintains the riparian forest canopy that shades these streams, keeping water temperatures within the narrow range bull trout require to survive. Historical grazing removed this protection in adjacent areas, contributing to documented population declines; the McClellan Mountain IRA's intact riparian buffer is now critical to preventing further losses in the Malheur River watershed.

Whitebark Pine and High-Elevation Refugia

Whitebark pine (Pinus albicaulis), a federally threatened species and IUCN-listed endangered species, occurs in the subalpine fir and alpine sagebrush shrubland zones at higher elevations within the area. This species is retreating upslope and to higher latitudes as climate warms, making intact high-elevation habitat increasingly valuable as a climate refugium. The roadless condition preserves the elevational gradient from lower montane ponderosa pine through mixed conifer and subalpine zones—connectivity that allows whitebark pine and associated species to shift their ranges as conditions change, rather than becoming isolated on fragmented peaks.

Unfragmented Forest Interior for Gray Wolf and Large Ungulates

The 21,213-acre roadless expanse provides continuous interior forest habitat across multiple elevation zones and mountain ridges, essential for gray wolves (Canis lupus), a federally endangered species recolonizing the Blue Mountains, and for mule deer and elk that use the area as summer range and security cover. Gray wolves require large territories with minimal human disturbance and road access; the absence of roads eliminates the corridors that facilitate poaching and vehicle strikes. The interconnected forest canopy across McClellan Mountain, Fields Peak, Riley Mountain, and Moon Mountain allows these large carnivores and ungulates to move between seasonal ranges without crossing developed landscapes.

Native Pollinator and Plant Communities

Suckley's cuckoo bumble bee (Bombus suckleyi), proposed federally endangered, and monarch butterfly (Danaus plexippus), proposed federally threatened, depend on native wildflower and sagebrush communities that persist in the roadless area's varied ecosystems—from mountain-mahogany shrubland to Douglas-fir/western larch forest. Road construction and the associated soil disturbance create corridors for invasive cheatgrass (Bromus tectorum), which outcompetes native bunchgrasses and forbs that these pollinators require for nectar and larval host plants. The roadless condition prevents the fragmentation and weed invasion that would degrade these communities.

Threats from Road Construction

Stream Sedimentation and Temperature Increase from Canopy Removal

Road construction requires cutting slopes and removing riparian forest to create roadbeds and sight lines, particularly acute in the steep terrain of McClellan Mountain and the Aldrich Mountains. Exposed cut slopes erode during spring snowmelt and summer storms, sending sediment into Riley Creek, McClellan Creek, Wickiup Creek, Buck Cabin Creek, and Moon Creek. Simultaneously, removal of the riparian canopy allows direct sunlight to warm these tributaries. Bull trout (Salvelinus confluentus) cannot tolerate sustained water temperatures above 13°C; even a 2–3°C increase from canopy loss can render spawning and rearing habitat unsuitable. Once sedimentation fills the gravel interstices where bull trout eggs incubate, recovery requires decades of natural sediment flushing—a process that cannot occur if the road remains a chronic erosion source.

Habitat Fragmentation and Edge Effects for Gray Wolf and Forest Interior Species

Road construction fragments the 21,213-acre roadless block into smaller, isolated patches, reducing the continuous interior forest that gray wolves require for denning, hunting, and movement without human interference. Roads create "edge habitat"—the transition zone between forest and open roadside—where predation risk increases, visibility increases, and human access facilitates poaching. For whitebark pine (Pinus albicaulis) and associated subalpine species, fragmentation interrupts the elevational connectivity needed for climate-driven range shifts; populations become trapped on isolated high peaks rather than able to migrate to suitable microclimates. The loss of interior forest also increases nest predation and parasitism for songbirds and reduces security cover for elk and mule deer, making them more vulnerable to hunting pressure.

Invasive Cheatgrass Establishment and Wildfire Feedback Loop

Road construction creates disturbed soil corridors that are rapidly colonized by invasive annual grasses, particularly cheatgrass (Bromus tectorum), which is already documented as a significant threat in the Malheur National Forest. Cheatgrass dries earlier in summer than native bunchgrasses, creating a continuous fine-fuel layer that increases fire frequency and intensity. This feedback loop converts native sagebrush and grassland communities—essential habitat for Suckley's cuckoo bumble bee (Bombus suckleyi) and monarch butterfly (Danaus plexippus)—into cheatgrass monocultures that support neither native pollinators nor their host plants. Once established, cheatgrass-dominated landscapes are difficult to restore; the roadless condition prevents the initial disturbance that triggers this conversion.

Culvert Barriers and Loss of Aquatic Connectivity

Road crossings of Riley Creek, McClellan Creek, Wickiup Creek, Buck Cabin Creek, and Moon Creek require culverts or bridges. Improperly sized or installed culverts create velocity barriers that prevent bull trout (Salvelinus confluentus) and steelhead (Oncorhynchus mykiss) from moving upstream to spawning habitat or downstream to rearing areas. Even where culverts do not completely block passage, they fragment populations into isolated subunits, reducing genetic diversity and increasing extinction risk. The Upper John Day River basin has already experienced documented bull trout declines; further fragmentation of the remaining cold-water tributaries that originate in the McClellan Mountain IRA would eliminate critical refugia for this federally threatened species.

Hiking, Backpacking, Mountain Biking, and Horseback Riding

The McClellan Mountain Roadless Area offers non-motorized trail access across 21,213 acres of montane forest and high country. McClellan Mountain Trail #216 is the primary route—a 10.2-mile non-motorized trail rated easy to moderate, climbing from 5,600 to 7,400 feet with approximately 1,800 feet of elevation gain. Hiking time is 5 to 6 hours. The trail is open to hikers, backpackers, mountain bikers, and horseback riders. Access the trail from the Riley Creek Trailhead or the Fields Peak–McClellan Mountain Trailhead. Riley Creek Trail #216A connects to McClellan Mountain Trail #216 from the Riley Creek Trailhead and provides alternative access to the high country. The typical recreation season runs June through November; prepare for rapidly changing weather. The roadless condition of this area is essential to the experience—motorized vehicles are prohibited on Trail #216, preserving the quiet, secluded character that makes these routes attractive to non-motorized users seeking undisturbed backcountry travel.

Hunting

The McClellan Mountain area lies within the Northside Wildlife Management Unit (Unit 47) and supports hunting for Rocky Mountain Elk, Mule Deer, Black Bear, and Bighorn Sheep. Blue Grouse and Ruffed Grouse are documented small game species. Hunting typically occurs from late August through fall seasons; standard Oregon Department of Fish and Wildlife controlled hunt regulations and tag requirements apply. The prohibition of motorized vehicles on McClellan Mountain Trail #216 and throughout the interior roadless area means hunters must travel on foot or horseback—a requirement that maintains the semi-primitive character and quiet conditions essential to successful hunting in this remote terrain. Access points include the Riley Creek Trailhead, the Fields Peak–McClellan Mountain Trailhead, and the McClellan Trailhead (reached via Forest Road 21, FR 115, and FR 2160).

Fishing

Native Rainbow Trout, Redband Trout, and Bull Trout inhabit the headwater streams and tributaries of the Malheur River within the roadless area. These streams are managed for natural production of indigenous wild trout and mountain whitefish; hatchery stocking is limited to specific high-use areas and curtailed if it affects native populations. Fishing falls under Oregon's Southeast Zone regulations: the daily bag limit is two trout with an 8-inch minimum length, and streams are open year-round. Access to the interior is limited by steep terrain and the absence of roads; anglers reach fishable water via non-motorized trails. The roadless condition preserves the spawning habitat and cold-water stream conditions that support native trout populations and makes light-use fishing possible in a remote setting.

Birding

The area supports White-headed Woodpecker, Peregrine Falcon (nesting in Aldrich Mountain canyons), Clark's Nutcracker, Mountain Quail, Blue Grouse, Ruffed Grouse, Chukar, Bald Eagle, American Kestrel, Pileated Woodpecker, Common Raven, and various songbirds and sparrows. Spring and early summer are peak birding seasons, coinciding with wildflower blooms in meadows (late May through July) that attract birds and pollinators. Peregrine falcon nesting may result in seasonal closures of certain canyon areas. McClellan Mountain Trail #216 and Riley Creek Trail #216A provide non-motorized access for quiet wildlife and bird observation. The absence of roads and motorized traffic preserves the undisturbed forest interior habitat and quiet conditions necessary for observing forest songbirds and raptors.

Photography

Fields Peak (7,365 feet), the highest point in the Aldrich Mountains, offers 360-degree panoramic views of the John Day River Valley to the north and the Steens Mountains to the south. McClellan Mountain (7,044 feet) provides expansive views of the Strawberry Mountain Range to the east and Logan Valley to the southeast. Both summits are accessible via non-motorized trails and offer outstanding vistas from rocky crags and cliffs. Wildflower displays bloom in meadows along the trails from late May through July, with documented species including Scarlet Gilia, Phlox, Columbine, Balsamroot, Mule's Ears, Woodland Stars, and Hyssop. Wildlife photography opportunities include Bighorn Sheep, Mule Deer, Rocky Mountain Elk, Grouse, Clark's Nutcrackers, and Ravens. The roadless condition ensures that scenic vistas and wildlife habitat remain unfragmented and undisturbed by road construction and motorized access.
