Mt. Bushnell

Mt. Bushnell is a 41,798-acre Inventoried Roadless Area in Lolo National Forest, Montana, carved into the Coeur d'Alene Mountains at the state's western edge. The terrain is mountainous and montane, framed by Mount Bushnell, Table Top Mountain, Cameron Peak, Goat Mountain, Hawk Mountain, and Tarbox Hill, and crossed by East Fork Pass, Joan Creek Pass, Daisy Creek Pass, Knox Pass, Taft Summit, and the C C Divide. The area lies at the Dry Creek headwaters within the broader Clark Fork watershed. Water radiates from the high divides through a dense network of named streams — Daisy Creek, East and West Twin Creek, Middle Fork Savenac Creek, Packer Creek, Timber Creek, Joan Creek, Savenac Creek, Knox Creek, and Wilkes Creek — cold, steep headwater tributaries carrying snowmelt and springflow to the mainstem below.

Forest cover shifts sharply with elevation and aspect. On warm lower slopes, Northern Rockies Ponderosa Pine Woodland carries ponderosa pine (Pinus ponderosa) above arrowleaf balsamroot (Balsamorhiza sagittata), bearberry (Arctostaphylos uva-ursi), and creeping Oregon-grape (Berberis repens). Mid-slope Southern Rockies Mixed Conifer Forest combines Douglas-fir (Pseudotsuga menziesii), western larch (Larix occidentalis), lodgepole pine (Pinus contorta), and grand fir (Abies grandis), with a huckleberry and thimbleberry understory. In cool, moist draws, Pacific yew (Taxus brevifolia) — near threatened on the IUCN Red List — grows beneath western hemlock (Tsuga heterophylla) and paper birch (Betula papyrifera), with devil's-club (Oplopanax horridus) and fairy slipper (Calypso bulbosa) at ground level. Rocky Mountain Subalpine Spruce-Fir Forest and Northern Rockies Subalpine Woodland and Parkland carry whitebark pine (Pinus albicaulis) along ridge crests. Avalanche chutes and subalpine meadows open the forest with streambank globemallow (Iliamna rivularis) and towering lousewort (Pedicularis bracteosa).

The streams carry westslope cutthroat trout (Oncorhynchus lewisi) and cedar sculpin (Cottus schitsuumsh), with Rocky Mountain tailed frog (Ascaphus montanus) and Columbia spotted frog (Rana luteiventris) in seeps and side channels. American three-toed woodpecker (Picoides dorsalis) works beetle-killed conifers, while Canada jay (Perisoreus canadensis) and Steller's jay (Cyanocitta stelleri) cache seed across the mid-canopy. Pacific wren (Troglodytes pacificus) and golden-crowned kinglet (Regulus satrapa) forage in subalpine fir shade, and flocks of evening grosbeak (Coccothraustes vespertinus) — vulnerable on the IUCN Red List — pass through conifer seed crops. Large mammals use the full elevation gradient: moose (Alces alces) browse streamside willow, wapiti (Cervus canadensis) and mule deer (Odocoileus hemionus) move between meadow and forest, and American black bear (Ursus americanus) forages on huckleberry. Gray wolf (Canis lupus) and coyote (Canis latrans) follow ungulate movements; calliope hummingbird (Selasphorus calliope) pollinates paintbrush and lousewort in subalpine meadows. Portions of this area fall within the potential range of several federally listed species; see the Conservation section for details.

A person climbing from the Dry Creek headwaters toward Mount Bushnell moves through distinct forest bands in the span of a few miles. Early walking along Savenac Creek passes through western larch savanna, where slender pillars filter light onto a red-needled floor. Across Joan Creek Pass and the C C Divide, the canopy breaks into open subalpine parkland; whitebark pine stands on Cameron Peak and the ridgelines above. At Daisy Creek Pass and Knox Pass, the sound of water falls away and wind moves through subalpine meadows and avalanche-shattered slopes. Along the high divide toward Goat Mountain and Hawk Mountain, the Coeur d'Alene Mountains open westward in successive, deeply cut ridges.

The Mt. Bushnell country lies within the traditional homelands of the Salish, Pend d'Oreille, and Kootenai peoples, whose seasonal travel, hunting, and gathering patterns long crossed the Clark Fork watershed that forms the lowland margins of the area.

European-era land use accelerated rapidly in the late nineteenth century. Mineral and Sanders counties — where Mt. Bushnell lies — were reshaped by silver, copper, and gold mining camps and by the push of transcontinental railroads through the St. Regis and Clark Fork valleys. Sawmills such as the Mann Lumber Company at Henderson operated "near present-day Cabin City Campground in the Lolo National Forest" [5]. Industrial logging to supply the booming copper industry reached into the valleys draining the roadless area; the Anaconda Copper Mining Company sawmill at Bonner, together with allied mills at Polleys in Missoula and J. Neils in Libby, defined timber demand across the Northern Region [2]. Kenneth Ross served as General Manager of the Lumber Department of the Anaconda Copper Mining Company [2].

Federal stewardship followed quickly. "Congress responded to the threat, authorizing the National Forest reserves in 1891" [4], and "by 1897 millions of acres had been set aside, including the Flathead and the Bitterroot reserves in Montana" [4]. "In 1905 Congress created the National Forest Service and hired rangers to patrol these vast public lands" [4]. "The Forest Homestead Act, passed in June 1906, opened land within the national forests" [1]. "Three months later, a presidential proclamation established the Lolo Forest Reserve (now Lolo National Forest)" [1].

The country around Mt. Bushnell became a laboratory of early American forestry. "Creation of the National Forest Service in 1905 brought Elers Koch, one of the nation's first professional foresters, to inspect and evaluate the Forest Reserves of Montana and Wyoming" [3]. "Appointed Forest Supervisor of the Bitterroot and Lolo National Forests in 1907, Koch happened upon the abandoned homestead of a German settler named Savennach" [3], adjoining what is now the roadless area. "Work began in 1908 and just as the first pine seedlings were ready for transplanting in 1910, fire swept through the region scorching 3 million acres of timberland" [3]. That catastrophic fire season — remembered as the 1910 "Big Burn" — drove the Forest Service's commitment to fire suppression and to the construction of thousands of fire lookout towers across the Northern Region [4]. Savenac Nursery, rebuilt after the fire, supplied seedlings to reforest burned ground; photographs document a "horse-drawn wagon... loaded with 100,000 pine seedlings" [5]. "The Civilian Conservation Corps rebuilt and modernized the facility a final time between 1932 and 1948" [3], and Savenac operated until regional reorganization brought closure in 1969 [3].

Mt. Bushnell is a 41,798-acre Inventoried Roadless Area within Lolo National Forest, managed from the Plains/Thompson Falls Ranger District in the USFS Northern Region and protected under the 2001 Roadless Area Conservation Rule.

Vital Resources Protected

• Cold Headwater Stream Integrity: The 41,798-acre Mt. Bushnell roadless block protects the Dry Creek headwaters and a dense network of steep, snowmelt-fed tributaries — Daisy Creek, East Fork Timber Creek, Middle Fork Savenac Creek, Packer Creek, and Wilkes Creek — flowing out of Rocky Mountain Subalpine Streamside Woodland and Northern Rockies Subalpine Woodland and Parkland. Without roads, these streams retain the cold water temperatures, low sediment loads, and intact spawning gravel that bull trout (Salvelinus confluentus), westslope cutthroat trout (Oncorhynchus lewisi), and Rocky Mountain tailed frog (Ascaphus montanus) require. Undisturbed channels also carry the cedar sculpin and cold-water invertebrate fauna that anchor the aquatic food web in the broader Clark Fork system.

• Subalpine Ecosystem Integrity: The high country — the C C Divide, Cameron Peak, Goat Mountain, and Mount Bushnell itself — supports Rocky Mountain Wet and Dry Subalpine Spruce-Fir Forest and Northern Rockies Subalpine Woodland and Parkland, carrying whitebark pine (Pinus albicaulis) at ridge elevations. The roadless condition preserves continuous old-growth structural complexity and the whitebark pine–nutcracker seed-dispersal relationship that underpins the subalpine food web. It also maintains climate refugia for species tracking cool conditions upslope as regional temperatures rise.

• Elevational Gradient Connectivity: An unbroken forest fabric from dry foothill sites (Northern Rockies Foothill Pine Wooded Steppe) through Southern Rockies Mixed Conifer Forest and Rocky Mountain Lodgepole Pine Forest to subalpine ridges allows seasonal movement for Canada lynx, grizzly bear, North American wolverine, moose, and wapiti. The roadless state maintains the large home ranges and low-disturbance corridors these species require, and holds the late-seral forest structure that supports interior-forest birds such as the evening grosbeak (Hesperiphona vespertina), listed as vulnerable on the IUCN Red List.

Potential Effects of Road Construction

• Sedimentation and Spawning Substrate Loss: Road construction across the steep Coeur d'Alene slopes produces chronic surface erosion from cut slopes and fills, delivering fine sediment to headwater channels such as Savenac Creek, Joan Creek, and Daisy Creek. Sediment smothers the clean gravel substrate that bull trout, westslope cutthroat trout, and Rocky Mountain tailed frog require for egg incubation, and culvert crossings fragment habitat and block spawning movements. Once fine sediment has accumulated in pool tails and redds, recovery requires decades of flushing flows.

• Habitat Fragmentation and Core-Area Loss: Roads cut through intact Southern Rockies Mixed Conifer Forest and Rocky Mountain Lodgepole Pine Forest create permanent linear edges that expose forest interior to wind, drying, and elevated light. Grizzly bear, Canada lynx, and wolverine avoid roaded country, so new corridors convert forest interior into edge habitat and shrink functional core area well beyond the roadbed itself. Fragmentation of late-seral structure is not reversible on human timescales.

• Invasive Species Introduction and Fire-Regime Alteration: Disturbed road corridors act as dispersal routes for spotted knapweed, sulphur cinquefoil, oxeye daisy, and Dalmatian toadflax, which have already established along roaded segments of the Lolo. Invasions alter the fine-fuels layer in ponderosa pine and larch savanna communities, shifting fire behavior and interfering with native understory regeneration. Combined with increased mechanized access that facilitates white pine blister rust spread in whitebark pine communities, road construction compounds landscape-scale vulnerability to large stand-replacing fires.

Mt. Bushnell occupies 41,798 acres of the Coeur d'Alene Mountains in Lolo National Forest, with backcountry access centered on native-material trails that radiate from low-elevation creek bottoms up to the C C Divide, Cameron Peak, and Mount Bushnell itself. The West Fork Dry Creek Trailhead is the primary maintained access point for the area, and Sloway Campground provides the nearest developed camping along the Clark Fork corridor. All trails inside the roadless area are surfaced in native material and are closed to motor vehicles, which keeps the footprint of use small and the walking-and-stock experience intact.

Hiking and horse packing are the dominant uses. Anchor routes include the CC Divide Trail (#404) — 31.0 miles along the high spine separating the Dry Creek and St. Regis drainages — and the Dry-Wilkes Divide Trail (#578), 10.6 miles along a connecting ridge. The Table Top Mountain Trail (#590, 7.6 miles) and the Wilkes Creek Trail (#584, 7.3 miles) open the western side of the area. Creek-bottom routes such as Savenac Creek (#263, 6.2 miles, hiker/horse), Packer Creek (#266, 2.8 miles), Joan Creek (#570, 3.8 miles), and West Fork Dry Creek (#572, 3.5 miles) climb from low water through Southern Rockies Mixed Conifer Forest into subalpine parkland. Dedicated summit approaches include Cameron Peak (#812, 4.7 miles) and Hawk Mountain (#811, 4.7 miles). Shorter spurs — Daisy Creek (#604, 5.6 miles), West Fork Knox Creek (#284, 1.5 miles), Knox Creek (#571, 4.9 miles), South Fork Wilkes Creek (#579, 3.4 miles), and Dry Creek-Hill 7 (#274, 2.2 miles) — allow point-to-point connections and day trips.

Winter recreation follows a separate, longer route network. The DeBorgia / Knox Pass route (SNO-70.12, 13.8 miles), the Saltese/Randolph Creek Loop (SNO-70.01, 20.7 miles), and the Meadow Mtn Loop (SNO-70.02, 5.4 miles) carry snow travel through the foothills and onto the C C Divide. Snow typically lingers at the upper elevations of Mt. Bushnell and the CC Divide into late spring.

Fishing is directed to the cold headwater streams that drain the area. Westslope cutthroat trout (Oncorhynchus lewisi) and brook trout (Salvelinus fontinalis) occur in the main creeks, with cedar sculpin (Cottus schitsuumsh) in the lower reaches. Anglers working Savenac Creek, Packer Creek, Joan Creek, and Dry Creek reach small-stream fisheries accessible only by foot or horse. Montana statewide fishing regulations apply; bull trout are catch-and-release where encountered.

Hunting follows Montana Fish, Wildlife and Parks seasons and tag allocations. Wapiti (Cervus canadensis), mule deer (Odocoileus hemionus), and white-tailed deer (Odocoileus virginianus) use the full elevation gradient between low winter range and subalpine summer range. Ruffed grouse (Bonasa umbellus) is the primary upland bird; American black bear (Ursus americanus) is hunted in season. Moose (Alces alces) occur under limited-entry permit.

Birding is strong at the low-elevation hotspots along the Clark Fork. The Thompson Falls town hotspot records 191 species across 510 checklists, and Thompson Falls Reservoir and Thompson Falls–Island Park add waterbird and riparian coverage close to the area boundary. Lookout Pass Ski Area and the Dena Mora Rest Area sample higher-elevation and pass-country communities. Inside the roadless block, interior-forest species — Pacific wren (Troglodytes pacificus), golden-crowned kinglet (Regulus satrapa), Townsend's warbler (Setophaga townsendi), and American three-toed woodpecker (Picoides dorsalis) — are characteristic of the mixed-conifer and subalpine forest communities, and calliope hummingbird (Selasphorus calliope) works subalpine meadows.

Photography opportunities follow the trail network — ridge light from Cameron Peak, Hawk Mountain, and the CC Divide; western larch color in late October along Savenac and Packer Creeks; avalanche-chute wildflower communities in July.

What makes each of these activities possible is the absence of roads. Trails remain trails, headwater streams carry clean sediment-free water, and the elevational gradient from foothills to subalpine ridge remains walkable as a single continuous landscape. Road construction would convert much of that to motorized travel and shorten every experience described above.
