Unit 329
3
High alpine basins and rolling ridges along the Montana-Idaho border ideal for mountain goat terrain.
Hunter's Brief
Horse Prairie North spans high country between Clark Canyon and Lemhi Pass with elevations consistently above 6,300 feet. The unit features scattered timber mixed with open alpine meadows and rocky basin country. Access via Routes 278 and 324 plus the Trail Creek-Lemhi Pass Road provides fair entry points, though terrain becomes progressively steeper and more remote away from major routes. Water is limited at higher elevations—reliable springs and creeks are critical to hunt planning. The rolling topography and moderate forest cover create classic mountain goat habitat across multiple basins.

Terrain Deep Dive
Landmarks & Navigation
Key terrain features include Independence Peak, Lookout Mountain, and War Eagle Mountain as primary navigation points and glassing vantage locations. The Bloody Dick-Big Hole Divide provides the northern spine of the unit with multiple ridgelines offering long-distance visibility. Boulder Pass offers a natural travel corridor and water opportunity between basins.
Baboon Mountain and Roundhead Butte serve as distinctive eastern reference points. These summits and ridges create natural glassing stations for spotting goats at distance across open alpine terrain—critical for a unit where terrain complexity and vertical relief demand methodical reconnaissance before stalking.
Elevation & Habitat
The entire unit sits in upper-elevation country, ranging from 6,300 to nearly 11,000 feet with a median elevation of 8,675 feet. This elevation band supports sparse to moderate coniferous forest interspersed with extensive alpine meadows, talus slopes, and rocky basins—classic mountain goat terrain. The vegetation transitions from scattered timber at lower ridges to open alpine terrain at higher elevations.
Sagebrush meadows like Frenchy Meadow provide openings for glassing, while basins such as Elk Creek, Telephone, and Hummingbird offer protected terrain and seasonal water sources critical for goat hunting.
Access & Pressure
Approximately 176 miles of road network provide fair access, concentrated along Routes 278 and 324 plus the Trail Creek-Lemhi Pass Road. Road density is moderate, meaning most hunters stage from these main corridors and focus on nearby basins and ridges. The Bannack-Grant Road and Skinner Meadows-Jackson Road offer secondary access into the interior.
Despite fair road access, the high elevation and rolling terrain limit where most pressure concentrates—the accessible basins fill up early season, while higher ridges and remote basins remain less crowded. Independence serves as the closest staging point.
Boundaries & Context
Unit 329 occupies the high country of southern Beaverhead County, anchored by Clark Canyon Dam to the south and Lemhi Pass on the Montana-Idaho border to the west. The unit encompasses roughly 176 miles of road access across rolling ridgelines and alpine basins bounded by major drainages: Grasshopper Creek and Interstate 15 define the eastern margin, while the Bloody Dick-Big Hole Divide marks the northern extent. The terrain is substantial enough to provide genuine solitude away from road corridors, yet accessible enough that the primary ridges and basins see regular pressure during hunting season.
Water & Drainages
Water is limited at these elevations, making the location of reliable springs and streams central to success. Basin Creek, Beaver Creek, Sheep Creek, and Bull Creek systems provide the primary water drainages; seasonal flows vary significantly. Higher basins like Elk Lake and Hidden Lake offer alpine water sources but are often unavailable until mid-season.
The headwaters of these drainages typically hold water longer into fall. Hunters must scout water sources early in the season—drying creeks at altitude force goats to concentrate near reliable sources, which can shift dramatically week to week.
Hunting Strategy
Mountain goat hunting in Unit 329 requires glassing-intensive tactics from high vantage points. Focus on Independence Peak, Lookout Mountain, and ridgelines with exposure to multiple basins—use extended optics to locate goats before attempting approaches. Early season targets the accessible high meadows like Frenchy Meadow and lower basin country.
As season progresses and hunters increase, goats retreat to steeper, rockier terrain near Monument Peak and the upper divide country. Water location dictates goat movement; scout Sheep Creek, Bull Creek, and basin lakes early. The rolling terrain demands patience—expect multiple-day glassing efforts and long stalks once goats are located.
Terrain complexity suggests hiring an outfitter unless you're comfortable navigating alpine terrain.
