Unit 72

Blackfoot Reservoir serves as the unit's dominant water feature and central navigation anchor. The Blackfoot Lava Field defines the western terrain, offering distinctive volcanic country for glassing and orientation. The Ninety Percent Range and Chesterfield Range frame the northern boundary and provide ridge vantage points.

Swaps Pass, Devils Gate, and Tenmile Pass are notable gaps useful for understanding access routes and movement corridors. Sawmill Ridge, Long Ridge, and Corral Creek Ridge offer higher ground for surveying sagebrush basins. The system of creeks—Tenmile, Indian, Spring, and Wilson—provides navigation corridors through the flats and draws.

Elevations climb gradually from around 5,300 feet in the basin floors to just over 7,200 feet on the higher ridges, creating a relatively confined vertical band. The terrain is predominantly sagebrush and grassland with scattered stands of juniper and limber pine, concentrated on north-facing slopes and the Blackfoot Lava Field margins. Most of the unit sits in the high-desert zone where vegetation is sparse and open.

Volcanic terrain—particularly the dark lava flows—creates visual contrast and provides patches of rougher country. The flats dominate, offering good visibility but limited shade; higher ridges and draws offer timber and cooler habitat for summer use.

Over 450 miles of roads crisscross Unit 72, creating fair accessibility throughout the plateau. Communities like Soda Springs, Henry, Chesterfield, and Meadowville provide logical staging points with services and camping infrastructure. The road network suggests moderate hunting pressure is spread across the basin and ridge systems rather than concentrated in specific canyons.

The open, rolling terrain means hunters can stage in multiple locations and cover ground efficiently. Fair access suggests less competition than highly connected areas but more traffic than truly remote terrain. Spring and summer access is straightforward; fall hunting may encounter rougher conditions on higher passes.

Unit 72 encompasses the high-desert plateau country straddling Bingham and Caribou counties in southeastern Idaho. The unit sits at the interface of the Snake River Plain and the upland basins to the east, characterized by volcanic features and basin topography. Soda Springs and the nearby towns of Henry, Chesterfield, and Meadowville provide reference points for the region.

The landscape is bookended by the Blackfoot Lava Field to the west and the Ninety Percent Range and Chesterfield Range to the north, anchoring the unit's geographic extent. This is accessible plateau country where roads connect scattered ranches and communities across the sagebrush.

Blackfoot Reservoir is the primary water feature, providing reliable surface water central to the unit. A robust network of named springs—Chandler, Hibner, Indian, Mammoth, Cold, Ninety Percent, and others—indicates consistent groundwater availability across the high-desert plateau. Multiple creeks drain the unit, including Tenmile, Indian, Spring, Wilson, and Coyote creeks, though flow varies seasonally.

Warbonnet Creek and Sunday Creek offer additional drainage corridors. The spring-fed system makes this water-abundant country compared to surrounding desert basins. Hunters should plan around these sources and the reservoir for reliable camp water throughout the season.

Unit 72's open sagebrush and sparse-timber character suits hunters comfortable glassing from distance and pursuing game across rolling country. The flat to rolling topography allows effective reconnaissance from ridges and vantage points overlooking the basins. Tenmile Creek, Indian Creek, and Spring Creek drainages funnel wildlife movement and offer cooler habitat in summer.

The Blackfoot Lava Field and its margins provide rougher escape terrain. Water sources—springs throughout the unit plus the reservoir—concentrate wildlife during dry periods. Early season hunters should focus on higher timber and spring-fed draws; later season pursuits benefit from the plateau's exposure and visibility.

The modest complexity rating reflects straightforward terrain navigation, making this country approachable for hunters with moderate backcountry experience.
