Asotin Creek

The Asotin Creek Roadless Area encompasses 16,433 acres within the Umatilla National Forest in southeastern Washington. Its mountainous terrain occupies a system of ridges — Smoothing Iron Ridge, Sheep Ridge, Bracken Ridge, Sourdough Ridge, and Middle Point Ridge among them — broken by incised features including Horsethief Canyon, Grouse Gulch, and Sourdough Gulch, with elevated points at Pinkham Butte and Elk Point. The area drains through the North Fork Asotin Creek watershed, which includes Lick Creek and both the Middle Branch and South Fork of the North Fork. Multiple springs — Pinkham Spring, Willow Springs, Fourth of July Spring, Deadhead Spring, Red Fir Spring, and Bracken Springs — sustain cold-water streamflow through the dry summer months and feed riparian habitat across the watershed.

The area supports a broad range of ecological communities, reflecting steep gradients in moisture, elevation, and aspect. Northern Rockies Ponderosa Pine Woodland occupies lower, drier slopes and rocky outcrops, where bluebunch wheatgrass (Pseudoroegneria spicata), tobacco ceanothus (Ceanothus velutinus), and curl-leaf mountain-mahogany (Cercocarpus ledifolius) compose the understory. On north-facing slopes and wetter draws, Southern Rockies Mixed Conifer Forest supports grand fir (Abies grandis) and western larch (Larix occidentalis) above an understory of Lewis' mock orange (Philadelphus lewisii), mallow-leaf ninebark (Physocarpus malvaceus), and twinflower (Linnaea borealis). Open south-facing canyon walls carry Columbia Basin Canyon Grassland, where prairie smoke (Geum triflorum), northern mule's-ears (Wyethia amplexicaulis), and sticky geranium (Geranium viscosissimum) characterize the community. At higher elevations, Rocky Mountain Wet Subalpine Spruce-Fir Forest surrounds spring seeps, and subalpine meadow openings persist where snowpack lingers into late spring.

Confirmed wildlife occupies distinct vertical zones. Wapiti (Cervus canadensis) and bighorn sheep (Ovis canadensis) range across ridges and open rocky slopes; mountain lion (Puma concolor) move through the full elevational range. Dusky grouse (Dendragapus obscurus) and mountain quail (Oreortyx pictus) occupy mid-elevation brushy understories, while along stream corridors western toad (Anaxyrus boreas) and Pacific treefrog (Pseudacris regilla) use riparian margins. In the open ponderosa pine stands, Lewis's woodpecker (Melanerpes lewis) forages for insects and Williamson's sapsucker (Sphyrapicus thyroideus) excavates nest cavities in larger snags; flammulated owl (Psiloscops flammeolus) works the same forest edges after dark. Pacific yew (Taxus brevifolia), assessed as near threatened by the IUCN, grows as a shade-tolerant understory tree in the wetter mixed conifer zones. Portions of this area fall within the potential range of several federally listed species; see the Conservation section for details.

A traverse from canyon bottom to upper ridge passes through sharply distinct zones. Horsethief Canyon's walls frame open canyon grassland below, where golden eagle (Aquila chrysaetos) and northern harrier (Circus hudsonius) patrol thermals above exposed slopes. Climbing through ponderosa pine to the mixed conifer zone, Lick Creek's spring-fed corridors support streambank wild hollyhock (Iliamna rivularis) and Sitka valerian (Valeriana sitchensis). Near Pinkham Butte, forest gives way to subalpine shrubland dominated by square-twigged huckleberry (Vaccinium membranaceum). On the high points — Devils Tailbone Ridge, Hard-to-get-to Ridge, and Jump Off Joe Point — the plateau breaks steeply back into canyon walls, completing a vertical transect from sagebrush steppe to subalpine meadow within a few miles.

The name Asotin comes from a Nez Perce word meaning "the place of eels," applied because of the presence of this form of life in Asotin Creek [1]. For generations before European contact, the Nez Perce (Nimiipuu) — the dominant people of the Columbia Plateau — made seasonal use of the Blue Mountains and the drainages that would become Asotin County. They wintered at the mouth of the Asotin where it empties into the Snake River [1]. One of the most-traveled Nez Perce summer routes ran southwesterly from the Lewiston area some fourteen miles to the junction of the North and South Forks of Asotin Creek, where trail marks remained distinct well into the twentieth century [1]. The trail was of great importance because it passed through prime hunting and gathering country in the Blue Mountains. Previous to the Nez Perce War of 1877, local settlers recorded that the Alpowa Indians under Chief Timothy were loyal and that the broader Native and settler communities lived in relative harmony [1].

American settlement of the county flanking the present roadless area accelerated in the 1860s and 1870s. By 1874, Henry Sharpnack had constructed the first sawmill in Garfield or Asotin County just above Columbia Center, a water-powered mill built almost entirely from wood without metal fasteners [1]. Livestock operations had already reached the mountains: sheep and cattle began to graze what would later become the Umatilla National Forest to a limited extent around 1875, with use intensifying year by year [1]. Before grazing regulations took hold, sheepmen drove their bands from the Pomeroy lowlands along a route that passed around the head of Lick Creek to Pinkham Butte, then crossed the North Fork of Asotin Creek at the Big Bend before climbing Smoothing Iron Ridge [1]. That route through the Asotin drainage was itself the product of local range politics: Peola cattlemen refused to let sheep cross their Pataha Creek holdings, forcing the herds onto the longer Asotin Creek passage [1].

Timber cutting raised its own legal conflicts. In December 1886, nearly all of the unsurveyed timberland in Garfield County became the subject of federal dispute; settlers who had long harvested fence rails, house logs, and firewood from public domain suddenly faced prosecution. The government tried the Henley Brothers in Pomeroy for cutting government timber, marking an early collision between informal frontier practice and federal land law [1].

The Wenaha Forest Reserve was created on May 12, 1905, by presidential proclamation of Theodore Roosevelt — one of the first formal protections for the Blue Mountains range [1]. On July 1, 1908, the Umatilla National Forest was established under the Forest Reserve Act of March 3, 1891, taking its name from the Umatilla River and the Umatilla tribe, members of the Confederated Tribes of the Umatilla Indian Reservation, whose people had long regarded these lands as central to their culture and livelihood [2, 3]. The Asotin Creek Roadless Area, administered by the Pomeroy Ranger District, is today protected under the 2001 Roadless Area Conservation Rule.

Vital Resources Protected

Cold-Water Stream Integrity

The Asotin Creek roadless area contains Bull Trout (Salvelinus confluentus) critical habitat within the North Fork Asotin Creek system, including Lick Creek and its tributaries. Bull Trout, federally listed as Threatened, require cold, clean, well-oxygenated water with stable streambanks and unobstructed fish passage — conditions that the roadless state preserves by eliminating the primary sources of chronic sediment input. Multiple spring sources — Pinkham Spring, Willow Springs, Fourth of July Spring, Deadhead Spring, Red Fir Spring, and Bracken Springs — maintain baseflows and water temperatures that sustain aquatic habitat through the dry summer months. Maintaining this system in a roadless condition protects the watershed's ability to function as a cold-water refugium as regional temperatures rise.

Elevational Gradient Connectivity

The area's montane terrain spans a nearly complete elevational continuum from Columbia Basin Canyon Grassland on lower canyon walls to Rocky Mountain Subalpine Meadow and Wet Subalpine Spruce-Fir Forest on the upper ridges. This uninterrupted gradient preserves movement corridors that wide-ranging species require: North American wolverine (Gulo gulo luscus), listed as Threatened, depends on connected subalpine habitats with persistent snowpack, while Spalding's Catchfly (Silene spaldingii), a Threatened plant, occupies grassland and shrubland communities that depend on intact fire regimes. The roadless condition prevents the fragmentation of this gradient, allowing species to track seasonal resources and shift distributions as climate conditions change.

Ponderosa Pine and Mixed Conifer Forest Integrity

The Northern Rockies Ponderosa Pine Woodland and Southern Rockies Mixed Conifer Forest communities depend on structural complexity — large-diameter trees, standing snags, and downed wood — that develops in the absence of road-associated disturbance. Yellow-billed Cuckoo (Coccyzus americanus), Threatened under the ESA, uses riparian woodland corridors within these forest types, while Suckley's cuckoo bumble bee (Bombus suckleyi), proposed for Endangered listing, depends on open native-plant communities where invasive grasses have not yet displaced the forb-rich understory. Documented threats to these forest systems include altered fire regimes, logging, and invasive exotic species — all associated with road access.

Potential Effects of Road Construction

Sedimentation and Aquatic Habitat Degradation

Road construction in the steep, montane terrain of Asotin Creek would introduce persistent sediment loading into the North Fork Asotin Creek watershed. Cut slopes and drainage crossings generate chronic fine-sediment inputs that smother spawning gravels and reduce the interstitial oxygen supply that Bull Trout eggs require for successful incubation. Once introduced, sediment sources associated with road prisms are difficult to stabilize and typically produce chronic impacts for decades even after road abandonment.

Habitat Fragmentation and Edge Effect Expansion

Roads divide interior forest blocks into smaller patches, converting core habitat into edge habitat along the full length of any new corridor. In the mixed conifer and ponderosa pine woodland communities, fragmentation reduces the area of structurally complex interior habitat available to species that require large undisturbed blocks — including wide-ranging carnivores such as mountain lion and wolverine. Edge effects — altered microclimate, increased shrub encroachment, and heightened predation pressure — penetrate well beyond the road corridor itself.

Invasive Species Establishment

Road corridors function as vectors for invasive plant establishment, exposing disturbed mineral soil that annual exotic grasses — particularly cheatgrass (Bromus tectorum), documented within this area — colonize preferentially. Documented threats to the Columbia Basin Canyon Grassland, Great Basin Big Sagebrush Steppe, and Palouse Prairie communities include exactly this pattern: annual non-native species invasion accelerated by soil disturbance and altered fire regimes. Once established, cheatgrass shortens fire return intervals and converts perennial grassland communities to annual monocultures — a shift that is exceptionally difficult to reverse.

The Asotin Creek Roadless Area covers 16,433 acres of mountainous terrain in the Umatilla National Forest, southeastern Washington — a vertically diverse landscape of canyon grasslands, ponderosa pine ridges, mixed conifer draws, and subalpine meadows. Wickiup CG provides the area's developed camping, serving as a base for day and overnight excursions into the surrounding terrain. No maintained trail network crosses the area, making it primarily suited to dispersed cross-country travel on open ridgelines and through the connected canyon systems.

Hunting

The area supports well-documented hunting opportunity for wapiti (Cervus canadensis) and bighorn sheep (Ovis canadensis) across its ridge and canyon systems. Mountain quail (Oreortyx pictus) and dusky grouse (Dendragapus obscurus) occupy brushy mid-elevation understories and forest-grassland edges that characterize much of the middle elevations. Sheep Ridge and Elk Point — both named features within the roadless area — reflect the long association between this terrain and its ungulate populations. The roadless condition sustains the interior cover, undisturbed browse, and low-traffic character that support these populations across the landscape.

Wildlife Watching and Birding

The area's broad elevational range and habitat mosaic support a diverse confirmed bird list. Golden eagle (Aquila chrysaetos) and northern harrier (Circus hudsonius) hunt open canyon grasslands and sagebrush steppe on the lower slopes. In the ponderosa pine stands, Lewis's woodpecker (Melanerpes lewis) and Williamson's sapsucker (Sphyrapicus thyroideus) work larger-diameter trees, while flammulated owl (Psiloscops flammeolus) occupies the same habitat after dark. Lazuli bunting (Passerina amoena) and vesper sparrow (Pooecetes gramineus) are confirmed in open brushy areas; gyrfalcon (Falco rusticolus) has been recorded in the vicinity. Three eBird hotspots within 24 km document the broader area's avian richness: Rainbow Lake records 105 species from 63 checklists, Grande Ronde River at Boggan's Oasis 83 species from 61 checklists, and Cloverland Flats 59 species from 83 checklists.

The area also supports viewing of larger mammals. Wapiti and bighorn sheep are visible along open ridgelines, particularly on Smoothing Iron Ridge and Sheep Ridge. Mountain lion (Puma concolor) and snowshoe hare (Lepus americanus) share the forest interior, while Columbian ground squirrel (Urocitellus columbianus) occupies meadow openings at higher elevations.

Backcountry Character

Horsethief Canyon, Devils Tailbone Ridge, Hard-to-get-to Ridge, and Jump Off Joe Point are the kinds of terrain features that define this area — steep, remote, and navigable on foot but not accessible by vehicle. The absence of roads eliminates the motorized traffic and habitat fragmentation that degrade dispersed recreation quality. Cross-country routes along the upper ridges and through the canyon drainages remain free of the invasive plants and edge disturbance that road corridors introduce. For hunters, wildlife watchers, and backcountry users, the roadless condition is the defining feature — it maintains the ungulate cover, intact canyon grasslands, and undisturbed upper ridges that make these activities possible here.
