Unit South Hills
Vast high-desert basin country with scattered buttes, limited water, and complex terrain spanning remote sagebrush flats to juniper-studded ridges.
Hunter's Brief
South Hills is a sprawling, high-complexity desert unit dominated by open sagebrush basins, scattered rock formations, and isolated ridges. The terrain is mostly low-elevation desert and semi-arid country with sparse timber on higher slopes. Access via a well-developed network of ranch roads and crossings is excellent, but water is scarce and navigation demands careful planning. Elk inhabit the unit, typically at higher elevations and in canyon drainages where water concentrates. This is big country that rewards self-reliant hunters comfortable with distance and minimal water sources.

Terrain Deep Dive
Landmarks & Navigation
Register Rock, Twin Sisters, and Balanced Rock stand as distinctive rock formations useful for orientation across the open country. Bruneau Dunes and Columbet Table provide visible reference points; Castle Rocks and the East Hills define edges. Multiple passes—Beaverdam, Lyman, Summit Springs, and Trout Creek—serve as traditional travel corridors through ridge systems.
Salmon Falls, Phantom Falls, and Ross Falls mark drainage confluences where water concentrates. The Arch, Crows Nest, and various named buttes scattered throughout offer glassing platforms. Poison Creek Reservoir, Cedar Draw Lake, and Horse Lake are critical water landmarks that often dictate hunting routes in this water-scarce terrain.
Elevation & Habitat
The unit transitions from arid, shrub-covered basins in the lower elevations through juniper and scattered ponderosa on middle slopes, with sparse alpine timber on the highest ridges. Most terrain sits between 4,000 and 7,000 feet, creating a semi-arid ecosystem where sagebrush dominates the flats and draws, with grass and low brush on exposed slopes. Higher elevations support more robust timber coverage and cooler microclimates that attract elk during hot months.
The sparse forest density reflects the overall dryness—trees cluster along creeks and north-facing slopes while vast expanses remain open. Vegetation transitions are gradual rather than dramatic, with elevation gains often subtle across the broad basins.
Access & Pressure
Over 8,400 miles of roads crisscross South Hills, mostly ranch roads and crossings rather than maintained highways. This extensive network creates excellent logistics—staging from Bruneau or Murphy Hot Springs puts hunters close to multiple entry points. However, the sparse timber and open terrain concentrate visible pressure quickly; well-developed road systems mean multiple hunters can access country rapidly.
Crossings like Three Island, Marshall Butte, and Deadhorse are traditional travel routes that see regular use. The vastness works both ways: it's big enough to absorb pressure, but obvious terrain funnels hunters into predictable patterns. Savvy hunters use the connected road system to reach less obvious basin edges and ridge saddles where fewer hunters venture.
Boundaries & Context
South Hills anchors a vast chunk of southwestern Idaho high desert, encompassing multiple basins and ridgelines from the Bruneau Desert through the East Hills and surrounding mountains. The unit spans from low desert valleys around 2,400 feet to alpine terrain above 10,000 feet, though the majority sits in the mid-elevation transition zone. Populated places like Bruneau and Murphy Hot Springs provide supply points at the periphery.
The landscape is characterized by isolated buttes, named basins, and scattered water features that serve as critical navigation landmarks in country that can feel featureless without them. Saylor Creek Air Force Range occupies a portion of the northern section.
Water & Drainages
Water is the limiting factor defining hunting strategy in South Hills. Perennial sources include East Fork Jarbidge River, Poison Creek, and the Malad River, but much of the unit relies on seasonal flows and scattered springs. Notable springs include Dead Horse, Cougar, Horse Springs, and Reynolds Springs—reliable benchmarks during dry periods.
Reservoirs like Keith, Grassy Hills, and Dry Fork concentrate water seasonally. Creeks like Clover, Cold Springs, and Devil Creek provide secondary drainages that typically flow in spring and early summer. Extensive irrigation infrastructure (canals, ditches, laterals) reflects agricultural development on lower elevations, but reliability depends heavily on season and location.
Successful hunting hinges on knowing which water sources hold through your planned hunt dates.
Hunting Strategy
Elk in South Hills primarily use the scattered ridgelines, canyon drainages, and higher terrain during warm months, dropping to lower elevations and water sources in fall. Early season success requires glassing from high vantage points like buttes and ridge saddles where visibility spans multiple basins; the open country rewards optics and patience over bushwhacking. Water sources become critical focal points as temperatures rise—position near reliable springs and reservoirs during mid-season.
Rut hunting concentrates around terrain breaks and saddles where bulls travel between basins. The sparse forest offers limited thermal cover, so elk rely on steep canyon walls and dense juniper pockets—hunt drainage heads and rocky outcrops. Distance is typical; be prepared to cover ground and navigate by landmarks rather than obvious trail systems.
