Unit 300

Key landmarks anchor navigation across this complex terrain. The Tendoy Mountains form the western spine; Three Eagles Peak and Medicine Lodge Peak provide prominent reference points from distance. Muddy Hole Basin and the various ridges—Lima Peaks, White Pine Ridge—serve as major glassing and staging areas.

Four Eyes Canyon and the Sweeney Gulch system are notable drainages for travel and moose hunting. Clark Canyon Reservoir and Keystone Reservoir mark eastern boundaries and serve as visual orientation points. Named springs including Nut Pine, Lake Canyon, and Porcupine are reliable water sources worth mapping.

These landmarks reduce navigation complexity in terrain that could otherwise feel overwhelming.

Terrain rises from the Clark Canyon area around 5,500 feet to peaks above 11,000 feet, with most hunting occurring in the 6,500 to 9,500-foot band. Sparse forest characterizes the landscape—scattered stands of whitebark pine, Douglas fir, and limber pine interspersed with open ridges and sagebrush basins. Willow bottoms and aspen groves mark water courses, providing both browse and cover.

The rolling topography creates natural funnels and valleys where moose congregate, especially where timber meets water. Higher elevation basins hold snow longer, concentrating animals in late season; lower country dries earlier, pushing moose upslope in summer and early fall.

Nearly 1,000 miles of maintained roads provide fair but not connected access—roads thread through the unit rather than form tight grids. Route 324 and the Trail Creek-Lemhi Pass Road (USFS 3909) are primary arteries; county roads branch into drainages and basins. I-15 at Dell provides the eastern entry point.

Road density is moderate enough that concentrated pressure exists near established trailheads and road-access camping, but vast areas remain lightly hunted. Early-season pressure focuses on accessible drainages; savvy hunters push deeper into the high basins where terrain complexity increases and most foot traffic dissipates. Most public land access occurs from scattered BLM/Forest Service roads; private land blocks require attention to boundaries.

Unit 300 occupies the high country along the Montana-Idaho border in southwestern Beaverhead County, bounded by Clark Canyon Dam to the north, Interstate 15 near Dell to the east, and the state line and Bannock Pass area to the south and west. The unit encompasses roughly 991 miles of road access threading through rolling mountain terrain. This is substantial country—complex enough to scatter pressure but accessible enough for hunters with basic backcountry skills.

The boundary traces through historically significant territory including old mining sites and established ranching areas, creating a patchwork of public and private holdings.

Despite the 'limited water' badge, this unit has reliable seasonal sources critical to moose hunting strategy. Major streams—North Fork Maiden Creek, Tendoy Creek, Cochran Creek, Indian Creek—run year-round and hold water in lower elevations. Named springs scattered throughout (Shooting Herders, Lake Canyon, West Kate Creek, Rock Spring, and others) provide reliable water, especially important in the higher basins where summer seeps dry.

Willow-lined bottoms concentrate moose in early season; late-season hunting requires understanding which creeks and springs hold water as flows diminish. The Clark Canyon and Keystone Reservoirs anchor the eastern side. Water source knowledge directly determines moose location patterns across the unit.

Unit 300 is moose country across its entire elevation range. Early season (September) targets bulls in rut, focusing on willow bottoms and aspen groves where bulls call and move. Glass the open ridges and basin edges during dawn/dusk; listen in timber edges where calling works.

Midseason hunting (late September-October) shifts to higher elevation basins as cows move upslope; bulls follow. Pursue water sources intensively—creeks and springs concentrate animals as temperatures cool. Late season (November) pushes remaining moose to lower elevations where timber is denser and snow hasn't driven them below the unit.

Terrain complexity (7.9/10) means route-finding is real work; mark springs and water sources on maps before season. Hunt above crowds by ascending into the higher basins early; patience and observation from glassing ridges pays dividends in this terrain.
