Unit 30

Upper Powder River

Foothills country bridging I-25 and the Bighorn National Forest with rolling terrain and scattered water.

Hunter's Brief

Unit 30 sits in the transition zone between the Powder River Basin and the Bighorn Mountains, characterized by rolling foothills with mixed sagebrush and scattered timber. The unit has fair road access via several county roads and Forest Service routes, making it moderately navigable for hunters. Multiple reservoirs and named creeks provide water throughout the unit, though springs and small streams are more reliable than permanent flow. This is solid deer country—mule deer and white-tailed deer both utilize the elevation gradients and habitat mix. Terrain complexity runs moderate to steep in places, so glassing from ridges pays off for locating animals.

Terrain Deep Dive

Landmarks & Navigation

The Horn and Tisdale Divide provide prominent ridge features useful for glassing and orientation across the foothills. The Mesa to the south and Cash Hill offer higher vantage points for scanning country. Crazy Woman Canyon Road and the various Forest Service roads provide key navigation corridors.

Springs named throughout the unit—Red Spring, Cash Spring, Charlie Brown Spring, and others—serve as water references and natural gathering points for deer. Beartrap Meadows and Bull Camp Park mark more open terrain useful for crossing and camping, while The Slip gap provides a navigable passage through steeper ground.

Elevation & Habitat

Terrain rises gradually from around 4,600 feet in the basin areas to nearly 9,250 feet on the higher ridges, with most of the unit falling in the mid-elevation range. The landscape transitions from sagebrush flats and open draws in the lower elevations to scattered ponderosa and Douglas fir timber on the slopes. Mixed sagebrush dominates the basin areas, while ridges support heavier timber stands.

This elevation spread creates distinct habitat zones that attract mule deer throughout the year—lower country in winter and fall, ridge country during summer months. The moderate forest coverage means good glassing country mixed with adequate cover for deer.

Access & Pressure

Fair road access via county roads and Forest Service routes means the unit is navigable without extreme difficulty, but roads are not densely networked. Highway 196 provides a northern access corridor, while the Mesa Road offers southern entry. Hazelton and the Mayoworth area serve as logical staging points for hunters.

The moderate accessibility means the unit won't feel remote, but it's not a high-pressure area either. Most traffic likely concentrates on lower-elevation areas near reservoirs and main roads. Hikers willing to move away from easy access points can find quieter country, especially in the western foothills approaching the national forest boundary.

Boundaries & Context

Unit 30 encompasses foothills country in Johnson County, bounded by Interstate 25 to the east and the Bighorn National Forest to the west. The unit stretches from Mayoworth and the Mesa Road area in the south to Highway 196 in the north, with Hazelton on the western edge serving as a reference point. The boundary follows county roads and Forest Service access routes, creating a moderate-sized unit that bridges lower elevation basin country and higher forested slopes.

This position makes it a natural transition zone for wildlife moving between elevation bands seasonally.

Water & Drainages

Water is moderately available but scattered, requiring advance scouting. Middle Fork Crazy Woman Creek and Muddy Creek represent the main drainages with more reliable flow, while Mattox Creek, Johnson Creek, and Spring Run are secondary options. Multiple reservoirs dot the unit—Horn Creek Reservoir, Seven Elk Reservoir, Purdy Reservoir, and others—though reservoir levels vary by season and irrigation demands.

Numerous springs including Red, Cash, Charlie Brown, Cole, and Donaldson provide supplemental water sources. Ditch systems indicate irrigation infrastructure in lower areas, meaning water availability downstream may be affected during growing season. Early season scouting to confirm reliable sources is essential.

Hunting Strategy

Both mule deer and white-tailed deer inhabit this unit across the elevation gradient. Mule deer favor the higher ridges and broken terrain in summer and fall, moving to lower sagebrush in winter. White-tailed deer use draws, timber patches, and creek bottoms year-round.

Early season hunting concentrates on higher ridge country where glassing is effective—use The Horn, Tisdale Divide, and similar vantage points to glass draws and benches. Mid-season rut hunting works draws and creeks where timber provides cover. Late season focuses on lower elevations and sagebrush flats where deer congregate.

Water sources like the reservoirs and springs become critical draws as season progresses. The rolling terrain requires patience and glassing skills rather than constant movement.
