Unit 27-3
High-country alpine terrain with steep drainages, scattered lakes, and demanding sheep habitat above the Middle Fork Salmon.
Hunter's Brief
This is serious mountain goat and bighorn sheep terrain with elevations climbing from moderate valleys into high alpine country. The unit straddles multiple drainages in the Lemhi and Valley County high country, accessed via Forest Service roads and scattered trailheads. Expect steep, timbered slopes broken by alpine meadows, talus fields, and significant elevation gain. Water is available but not abundant—plan around documented springs and high-country lakes. The terrain is complex and remote enough to reward preparation and fitness.

Terrain Deep Dive
Landmarks & Navigation
McEleny Mountain, Sugar Loaf, and Wilson Peak serve as major reference points for navigation and glassing throughout the unit. Remenclau Saddle provides a critical pass for accessing the upper drainages between the Middle Fork and northern boundaries. The high-country lakes—Paragon, Plateau, Ramshorn, Reflection, and Turquoise among them—cluster in the alpine zone and offer both water sources and terrain anchors for route planning.
Hot Springs and Warm Spring provide reliable lower-elevation water for base camps or access points. These features help break the vast drainages into huntable segments.
Elevation & Habitat
Elevations span from roughly 3,400 feet in the river valleys to above 9,600 feet on high ridges, with the median sitting near 7,200 feet—solid sheep country. The landscape transitions from dense timber in the lower to mid-elevations into increasingly open alpine terrain above 8,000 feet. High meadows like Hoodoo and Frog Meadows provide browse and sightline advantages, while timbered saddles offer travel corridors between drainages.
Steep mountainsides define the terrain—this isn't rolling country. The forest density stays significant even as elevation climbs, creating the kind of timbered alpine terrain sheep use for escape and thermal cover.
Access & Pressure
Nearly 280 miles of road thread through the unit, but access is concentrated on Forest Service routes and scattered trailheads rather than a dense highway network. The Emmett-Council Road, Sheep Creek Road, and FS618 provide the primary vehicle access corridors; from there, hunting becomes foot travel into the drainages. The terrain's steep, complex nature and moderate accessibility create natural dispersal—not everyone can or will push into the high alpine.
Pressure centers around roadhead trailheads; deeper canyon country sees lighter use. This is country that rewards those willing to go vertical and stay committed.
Boundaries & Context
Unit 27-3 encompasses the high-country drainages surrounding the Middle Fork Salmon River system in central Idaho's Lemhi, Valley, and Custer counties. The unit is bounded by the Middle Fork corridor to the south, with northern limits near the Salmon River's third fork and western boundaries along US-95 near Indian Valley. This is classic Frank Church-Wilderness Area adjacent terrain—rugged, interconnected drainages with limited road access feeding into the main river canyon.
The unit's complexity comes from the intricate network of side canyons, passes, and elevation transitions rather than size.
Water & Drainages
The Middle Fork Salmon anchors the southern boundary with consistent water flow, while Camas Creek drains a major portion of the unit's eastern terrain. Woolard Creek, Big Creek, and Blackeagle Creek offer reliable drainages for travel and water access in mid to lower elevations. Alpine lakes scattered across the high country—particularly the cluster around Terrace, Tip Top, and Twin Cove—provide critical water in the sheep zones but may be seasonal.
Springs are documented but limited; water scarcity in the upper drainages means careful planning around known sources. Overall, water exists but demands route planning rather than casual availability.
Hunting Strategy
Unit 27-3 is sheep-specific terrain. Mountain sheep thrive in the steep, cliff-studded drainages and high-country ridges, particularly around the major peaks and talus fields above 8,000 feet. Early season means glassing from high vantage points—McEleny Mountain and the ridges above Camas Creek offer long sightlines into the alpine basins.
Mid-season tactics shift toward glassing lower timbered slopes during thermal movement and pushing into remote saddles where sheep concentrate. Late season pushes animals lower into the protective timber. Physical fitness matters enormously; expect significant elevation gain from any trailhead.
Water planning is critical. Navigation in the maze of drainages demands careful map work and compass skills. This is not pickup hunting—come prepared for terrain complexity rated 8.4/10.
