Unit 29
Lemhi
High-elevation Lemhi Range terrain with rolling slopes, scattered timber, and challenging access into remote basins.
Hunter's Brief
Unit 29 sits in the Lemhi Range with elevations spanning roughly 4,000 to over 11,000 feet. The country transitions from lower sagebrush valleys into forested ridges and high alpine basins. Most terrain is public land, though access relies on an extensive but unpaved road network that can be seasonal. Water is scattered but present at springs, lakes, and high-country creeks. The complexity here demands solid navigation skills and patience working the drainages and basins.

Terrain Deep Dive
Landmarks & Navigation
The Lemhi Range dominates navigation and glassing opportunities, with Flatiron Mountain, Long Mountain, and Gunsight Peak providing visual anchors across the high country. Major basins—Copper Basin, Swan Basin, Baldy Basin, and First Basin—serve as natural gathering points and terrain breaks for hunting. Key drainages include Poison Creek, Paradise Creek, Trail Creek, and Copper Creek, which funnel animals through predictable corridors.
The Buck Lakes complex and Devils Lake provide reliable high-country references. Timber Creek Pass offers one of few natural travel routes across ridgelines, making it both asset and pressure point.
Elevation & Habitat
Terrain spans from roughly 4,000 feet in lower valleys to above 11,000 feet at high summits, with the median around 7,000 feet indicating substantial mid-elevation country. Lower elevations feature sagebrush and grassland valleys with scattered juniper and aspen. As elevation increases, ponderosa and Douglas-fir take hold on rolling slopes and canyon sides.
The high country above 9,000 feet transitions to subalpine terrain with whitebark pine, limber pine, and alpine meadows near major peaks like Flatiron Mountain and Gunsight Peak. This elevation spread creates distinct seasonal habitat zones that compress hunting strategies into narrow windows.
Access & Pressure
Over 950 miles of road network exist in and around Unit 29, but most are unpaved or seasonal forest service routes requiring high-clearance vehicles. Road density is uneven—denser near valley floors and staging areas like Tendoy and Leadore, sparse in the high basins. This creates predictable access corridors: most pressure concentrates along manicured entry roads, while upper basins and side drainages see lighter use.
Winter and early spring can limit access significantly. Hunters willing to park and pack gain substantial advantage over those road-bound. Connected road network benefits those with detailed maps and patience for slow travel.
Boundaries & Context
Unit 29 encompasses the Lemhi drainage and adjacent country in south-central Idaho's Lemhi County, anchored by the Lemhi Range as the dominant ridge system. The unit is bounded by State Highway 28 to the north and west, with the terrain extending into the high country of multiple named basins including Copper, Swan, Baldy, and First Basin. The town of Salmon sits nearby as a reference point, with smaller communities like Tendoy, Leadore, and Gilmore scattered at unit margins.
The Lemhi Range itself runs north-south through the unit, creating a backbone of high country that organizes drainage patterns and hunting opportunities.
Water & Drainages
Water exists but requires knowledge to find reliably. High-elevation lakes including Buck Lakes, Devils Lake, Everson Lake, and Dairy Lake hold water through hunting seasons. Numerous springs—Bull Spring, First Basin Spring, Cherry Spring, Nez Perce Spring, and others—support the high country, though spring reliability varies seasonally.
Major creeks including Poison Creek, Paradise Creek, and Copper Creek drain the unit but may be intermittent at lower elevations. Lower valley areas experience drier conditions, making high-country water sources critical to hunting strategy. Meadow Lake and Basin Lake provide additional insurance for water planning.
Hunting Strategy
Unit 29 is mid-to-high-elevation country suited for elk and mule deer across its elevation bands, with potential for mountain goat and bighorn in high basins (depending on current seasons). Lower sagebrush areas and aspen draws hold deer year-round. Elk summer in high basins and ridgetops, moving to mid-elevation slopes and canyon bottoms during late season. Early season hunting focuses on high country—Copper Basin, Swan Basin, Baldy Basin—where water and forage concentrate animals.
Mid-season requires working transition zones as elk drift downslope. Late season demands patience in snow-exposed basins and lower drainages. Terrain complexity and limited road-to-trailhead ratios reward self-sufficient hunters comfortable with navigation and off-trail movement.
