Manastash covers 11,155 acres of mountainous backcountry along the south side of the Cle Elum Ranger District in the Wenatchee National Forest, organized along Manastash Ridge and rising to Quartz Mountain, with named landforms at Rocky Saddle, Devils Slide, Frost Meadows, and Tripod Flat. The area sits on the watershed divide between the south-flowing South Fork Manastash Creek — a major hydrologic system in the Yakima basin — and the headwaters of the North Fork Wenas Creek. Cold water rises in Summit Spring, Milk Lake, Manastash Lake, Lost Lake, Shoestring Lake, and Devils Slide Lake, and runs out through Milk Creek and the South Fork Manastash before leaving the area; meadow wetlands at Hereford Meadow hold water on the divide itself.
Forest community structure traces the steep moisture and aspect gradients of the east Cascades. Northern Rockies Ponderosa Pine Woodland and Northern Rockies Foothill Pine Wooded Steppe occupy the warm, dry lower slopes, where ponderosa pine (Pinus ponderosa) stands open above antelope bitterbrush (Purshia tridentata), big sagebrush (Artemisia tridentata), and arrowleaf balsamroot (Balsamorhiza sagittata). Mid-elevation East Cascades Moist Mountain Conifer Forest and Southern Rockies Mixed Conifer Forest carry grand fir (Abies grandis), Douglas-fir (Pseudotsuga menziesii), western larch (Larix occidentalis), and lodgepole pine (Pinus contorta) over an understory of Geyer's sedge (Carex geyeri) and twinflower (Linnaea borealis). Higher up, Pacific Northwest Mountain Hemlock Forest and Rocky Mountain Wet Subalpine Spruce-Fir Forest hold mountain hemlock (Tsuga mertensiana), Engelmann spruce (Picea engelmannii), and subalpine fir (Abies lasiocarpa); whitebark pine (Pinus albicaulis, IUCN endangered) and western white pine (Pinus monticola, IUCN near threatened) cling to the highest ridgeline. Pacific Northwest Alpine Dry Grassland and Pacific Northwest Mountain Cliff and Talus open into thin-soil meadows where Kittitas larkspur (Delphinium multiplex) and Knoke's biscuitroot (Lomatium knokei, IUCN critically imperiled) bloom.
Wildlife sorts itself across these strata. American pika (Ochotona princeps) work the talus near the ridge crests; Cascade golden-mantled ground squirrel (Callospermophilus saturatus) hold the rocky edges of the high meadows; mule deer (Odocoileus hemionus) and wapiti (Cervus canadensis) graze the meadow openings; white-headed woodpecker (Leuconotopicus albolarvatus) and Lewis's woodpecker (Melanerpes lewis) hunt insects in the ponderosa pine, while Clark's nutcracker (Nucifraga columbiana) cache seeds in the whitebark pine. Streams support coastal tailed frog (Ascaphus truei), Cascades frog (Rana cascadae, IUCN near threatened), and westslope cutthroat trout (Oncorhynchus lewisi). Townsend's big-eared bat (Corynorhinus townsendii, IUCN vulnerable) forages above the meadow edges, and western rattlesnake (Crotalus oreganus) and pygmy short-horned lizard (Phrynosoma douglasii) sun on the lower exposed slopes. Portions of this area fall within the potential range of several federally listed species; see the Conservation section for details.
A walker climbing south up Manastash Ridge moves through the full elevational sweep in a few hours: ponderosa pine and arrowleaf balsamroot on the warm lower slopes, then closing into mixed conifer with the gold of western larch in autumn, then up into mountain hemlock parkland and Engelmann spruce around the headwater lakes. At Hereford Meadow the canopy gives way to wet meadow, and from the crest above Devils Slide the ground falls away into talus where pika call across the slope. Manastash Lake and Lost Lake sit in glacial pockets below the ridgeline, draining out as the South Fork Manastash Creek toward the Yakima River.
For thousands of years the upper Manastash Creek drainage at the southern edge of what is now the Cle Elum Ranger District lay within the homelands of the Psch-wan-wap-pams, the "stony ground people" also known as the Kittitas band of the Upper Yakama [1][2]. The Kittitas Valley below was one of only a handful of valleys in Washington where both camas and kouse root grew in abundance, drawing Yakama, Cayuse, Nez Perce and Wanapum gatherers each spring to dig, fish, race horses and trade [1]. Fur trader Alexander Ross, passing through in 1814, found a single gathering camp that he estimated at more than 3,000 men "exclusive of women and children, and treble that number of horses" [1]. On June 9, 1855, Yakama Chief Kamiakin and other tribal leaders signed a treaty with territorial governor Isaac Stevens that ceded all but a small reservation of the tribe's lands — about 10.8 million acres including the Kittitas Valley [1][3]. The treaty was not ratified until April 18, 1859, but Stevens advertised the lands as open to settlement within a month of the signing [1][3].
European-American activity reached the Manastash drainage almost immediately afterward. In July 1848 the Oblate Father Charles Pandosy founded the Immaculate Conception Mission on Manastash Creek near what would become Ellensburg, though the mission lasted only a year before its logs were eventually used for firewood [1]. Cattle ranchers moved their herds onto the open valley by the late 1860s, and prospectors first discovered gold around Swauk Creek in 1867 [2]. The county's logging industry was established in the early 1870s, concentrated in the western end of the county and fueled by demand for railroad ties [1][2]. The Cle Elum mining district to the north was established after Walter Reed and Pete Brosious discovered coal in 1884; the Northern Pacific Railroad arrived in 1886 and Cle Elum became a major coal mining district in Washington Territory [4]. Lumber mills were built to supply materials for the railroad, mines and homes for miners and their families [4]. In 1903 the Cascade Logging Company became the first large-scale commercial logging operation in the region [1].
Federal protection followed the conservation movement that swept the West at the turn of the century. President Theodore Roosevelt signed the proclamation creating the Wenatchee National Forest in 1908, placing the upper Manastash watershed under federal management [5]. Today the 11,155-acre Manastash Inventoried Roadless Area within the Cle Elum Ranger District is protected under the 2001 Roadless Area Conservation Rule.

Potential Effects of Road Construction
Manastash protects 11,155 acres of east-slope Cascade backcountry in the Cle Elum Ranger District of the Wenatchee National Forest, threaded by more than 30 maintained trails open to hikers, horse riders, and mountain bikes. The Manastash Trail (SNO-3100) runs 18.7 miles as the backbone of the trail system, with the Manastash Ridge Trail (4W306, 7.7 miles) and Manastash Ridge-West (1388, 1.8 miles) extending the ridgeline. The Quartz Creek Trail (949) covers 7.5 miles, and the Hereford Meadows Trail (1207, 4.3 miles) climbs to the wet meadow on the divide. Lake-access spurs reach Manastash Lake (Trail 1350, 4.0 miles), Shoestring Lake (Trail 1385, 3.1 miles), Lost Lake (Trail 1350.1, 0.2 miles), and Taneum Lake (1380, 1.0 miles). Additional trails — Tripod Flat (4W307, 4.4 miles), Kaner Flat (4W676, 7.3 miles), Rocky Saddle (1384), Frost Mountain (1366), Milk Creek (4W686), and Tipover (4W330) — connect the basins and ridges across the area.
Backcountry trips typically start at the Manastash T.H., Shoestring, or Riders Camp trailheads. No designated developed campground sits inside the area; dispersed camping along the trail corridors is the standard approach, with Manastash Lake, Lost Lake, and Shoestring Lake commonly used as overnight basecamps for ridge and lake circuits. Multi-day loops link Manastash Ridge, Hereford Meadows, Manastash Lake, and Tripod Flat through the mixed-conifer mid-elevation forest into the higher mountain hemlock parkland.
Winter use is substantial. Designated snowmobile trails include Bald Mtn (SNO-1701, 14.6 miles), Rock Creek Snowmobile (SNO-311185, 13.3 miles), Milk Creek Snowmobile (SNO-1708, 9.2 miles), and Gold Creek (SNO-1703, 9.6 miles), running along the ridge bench above the South Fork Manastash Creek drainage when snow is deep enough.
Fishing is available in Manastash Lake, Lost Lake, Shoestring Lake, Devils Slide Lake, and Milk Lake, and in the cold headwater channels of Milk Creek, the South Fork Manastash Creek, and the North Fork Wenas Creek. The lakes and streams hold rainbow trout, brook trout, and westslope cutthroat trout; bull trout are present in the lower Yakima system and require strict catch-and-release handling under current Washington Department of Fish and Wildlife regulations.
Hunting and wildlife viewing both benefit from the area's unbroken canopy and lack of road access. Mule deer and wapiti graze the higher meadows during fall and summer; the open ponderosa pine and Douglas-fir mid-elevations support white-headed woodpecker, Lewis's woodpecker, and Townsend's solitaire, while Clark's nutcracker work the whitebark pine on the highest ridges and American pika call from the talus. Bald eagle, golden eagle, peregrine falcon, and osprey hunt the ridgeline and lake margins; 22 eBird hotspots within 22 km — including Wenas Campground, Robinson Canyon, and Teanaway River Bridge — provide road-accessible birding for trip planning. Photographers will find the gold of western larch in autumn, glacier lily in early summer, and Kittitas larkspur on the open dry slopes.
What makes recreation here dependent on the roadless condition is the connected backcountry character: more than 100 miles of summer and winter trail run through unfragmented forest and ridge habitat, the lake basins and creek headwaters remain free of road-derived sediment and culvert barriers, and elk and deer populations move across the ridge without the disturbance corridors that roads create. Removing the roadless protection would shorten the unbroken trail experience, alter water quality in the South Fork Manastash and Wenas headwaters, and reduce wildlife concentrations that hunters and birders currently rely on.
