Unit 35
The rest of the state
High-desert basin country spanning sagebrush flats to scattered ridges across south-central Wyoming.
Hunter's Brief
Unit 35 is expansive high-desert terrain dominated by wide-open sagebrush basins, scattered breaks, and low ridgelines. Elevation ranges from lower desert valleys to moderate highlands, with sparse forest and limited water concentrated in seasonal drainages and scattered reservoirs. Access is challenging due to sparse road networks and substantial private land interspersion; much hunting requires careful planning around land ownership. The sheer size and terrain complexity demand strong navigation skills and self-sufficiency. Black bear habitat centers on the breaks and higher terrain where ponderosa pines appear.

Terrain Deep Dive
Landmarks & Navigation
The Palisades and Wamsutter Rim provide recognizable escarpment features for glassing across the lower basins. Jack Morrow Hills, Pumpkin Buttes, and Richeau Hills serve as navigation reference points across the open country. Springs like Pete Spring, Horsethief Springs, and Cogswell Spring mark critical water locations in an otherwise arid landscape.
Named draws including Fero Draw, Dan Draw, and Cedar Draw channel terrain and provide cover corridors through otherwise exposed terrain. The Eye of the Eagle arch and various rock formations like Ship Rock and Hat Rock offer visual anchors. Red Desert Basin, Adobe Town, and Indian Grove distinguish major topographic zones across this vast expanse.
Elevation & Habitat
Terrain transitions from lower sagebrush deserts in the 3,100-foot basins upward through rolling breaks into higher ridges reaching above 10,000 feet. Low-elevation country supports greasewood and rabbitbrush flats broken by scattered juniper and Wyoming big sagebrush. Middle elevations introduce ponderosa pine and Douglas-fir on north-facing slopes and benches.
Vegetation follows typical desert-to-forest patterns, with the sparsest timber concentrated at middle elevations on breaks like the Powder River Breaks and Hat Creek Breaks. Water-dependent vegetation clusters in canyon bottoms and drainage draws. The landscape feels genuinely open at lower elevations, growing more complex and timbered with each thousand feet gained.
Access & Pressure
Despite 21,000 miles of roads, much of Unit 35 remains difficult to access due to sparse distribution and substantial private land checkerboarding. The unit's immense size and terrain complexity mean most pressure concentrates near populated areas like Gillette and Casper and along major drainages where water exists. Vast sections remain lightly hunted simply due to remoteness and the effort required to navigate private land mosaics.
Road density remains limited across much of the unit; many areas require substantial hiking or horseback travel. Staging from Gillette or Casper is practical, though hunters should expect long drives to trailheads. Self-sufficiency and detailed land-ownership knowledge become critical success factors.
Boundaries & Context
Unit 35 encompasses vast territory across south-central Wyoming, spanning from the plains near Gillette and Casper westward into the remote Red Desert and Adobe Town country. The unit's northern boundary aligns with traditional breaks terrain, while southern portions merge into classic high-desert basins. Major population centers like Gillette and Casper sit outside the unit but serve as supply points.
The unit contains scattered military installations and numerous canals reflecting historical water development. Boundaries encompass a patchwork of public and private land requiring careful navigation; the sheer size makes this one of Wyoming's most geographically complex hunt areas.
Water & Drainages
Water is genuinely limited and requires prior scouting. Seasonal springs scattered throughout the unit provide unreliable water during dry periods. Reliable water sources include scattered reservoirs like Little Chief Reservoir, Big Chief Reservoir, and Gustin Reservoir, though many sit on private land or near ranch developments.
Major drainages include Powder River tributaries, Hat Creek, and North Sand Creek, though these often run intermittently. The Platte Valley and various irrigation ditches indicate water systems but most benefit ranches rather than hunters. In high-desert country like this, water knowledge separates successful hunts from forced exits.
Late-season hunting becomes particularly challenging; spring and early summer offer the best water access.
Hunting Strategy
Black bear inhabit the higher-elevation breaks and timbered ridges, particularly where ponderosa pine and Douglas-fir provide cover and food sources. Springs and water-dependent vegetation attract bears during dry periods, making reliable water locations hunting focal points. Successful strategy involves high-country glassing of ridges and benches during morning hours, then investigating timbered draws where bears shelter during heat.
Early season hunting capitalizes on bears moving through lower elevations; late summer concentrates bears near remaining water and food sources in higher terrain. The unit's extreme size rewards hunters willing to pack deep into less-accessible country where bears see minimal pressure. Navigation skills and self-reliance are mandatory; this is not casual country.
