Unit 36

Rock Creek

Bighorn Mountain foothills with rolling terrain, scattered timber, and critical water infrastructure along the I-90 corridor.

Hunter's Brief

Unit 36 straddles the transition zone between high Bighorn ridges and lower foothill country, with elevation ranging from valley floors to alpine terrain. Most land is public with scattered private parcels near towns. Well-connected by roads but much of the best country requires hiking into rougher terrain. Water is critical here—multiple creeks, lakes, and reservoirs dot the unit, but summer flows can be unpredictable. Expect to encounter irrigation infrastructure and some cattle presence in lower drainages.

Terrain Deep Dive

Landmarks & Navigation

Pilot Knob and Stone Mountain serve as excellent glassing landmarks from lower country. The Bighorn divide itself—running roughly north-south along the western boundary—provides constant navigation reference. Powell Creek, Johnson Creek, and multiple named draws create natural travel corridors through the unit.

Golden Lakes and Flatiron Lake offer alpine navigation points for high-country hunters. The irrigation ditch network (Rock Creek, Penrose, Hopkins, and others) marks lower terrain patterns and concentrates water in otherwise dry pockets. Florence Pass provides a recognized crossing point between major drainage systems.

Elevation & Habitat

The unit spans from mid-elevation valleys near 4,600 feet to high alpine basins above 12,800 feet, with most hunting taking place in the 7,000 to 9,500-foot band. Lower elevations feature sagebrush parks and grassland benches with scattered ponderosa pine; middle elevations transition to mixed conifer forest with open meadows; upper slopes support dense subalpine timber and tundra parks. The Bighorn divide creates a natural weather barrier, and aspect matters significantly—south-facing slopes dry out quickly while north-facing timber holds moisture and game longer.

This elevation spread means hunting patterns shift dramatically between early season and late season.

Access & Pressure

The unit has roughly 259 miles of road, creating a well-connected network that concentrates pressure near trailheads and lower drainages. Interstate 90 parallels the northern boundary, making access easy but visible. Most roads are secondary—Forest Service and county routes—rather than major highways, which keeps traffic moderate once away from I-90 corridor.

Private land near Buffalo and Kearny forces hunters onto public routes, creating choke points. The complexity score of 8.1 reflects how quickly terrain steepens; roads end early, forcing serious hiking into broken country where pressure drops significantly. Patient hunters willing to climb past road access find solitude.

Boundaries & Context

Unit 36 occupies the northeastern Bighorn Mountain front, bounded by Interstate 90 to the north and Interstate 25 to the east, with the high divide of the Bighorn range forming the western edge. The unit encompasses roughly 8,000 square miles of transition country where rolling foothills give way to steeper mountain slopes. Towns like Buffalo and Kearny sit at the eastern boundary, providing logical staging points.

French Creek drains the unit's eastern face while Piney Creek marks the northern boundary. This is working cattle country interspersed with public land, and irrigation has shaped water availability throughout.

Water & Drainages

Water availability is inconsistent and critical to strategy. Reliable year-round sources include Piney Creek, Powell Creek, and the major reservoirs (Huson, Reynolds, Mowry) concentrated in lower basins. Mid-elevation creeks like Johnson, Elk, and Ditch Creek run seasonally and depend on snowmelt; summer can mean dry beds.

The extensive ditch network (nine separate irrigation channels) maintains water in surprising places but creates unpredictable access. High alpine lakes—Golden, Powell, Elk, Flatiron, Florence, Gem, Deer, Frying Pan—hold water year-round but require substantial elevation gain. Early season hunters can water at creeks; late season requires knowledge of reliable springs or high basins.

Hunting Strategy

Unit 36 is elk country, pure and simple. Lower elevations (7,000-8,500 feet) hold elk early season and again in November, particularly in timber breaks and around water sources. Mid-elevations see peak elk use during the rut as bulls move toward high meadows.

Upper slopes and basins above 9,500 feet concentrate elk during September and again post-season. Use creeks and ditch systems as navigation and glassing reference points. The rolling terrain means spotting elk from ridges before pursuing into thick timber.

Early season means high-country scouting and evening water-hole watches; rut season means sound and movement up timbered draws; late season means knowing which snow-shadowed basins retain residual elk when higher country locks up. This is physically demanding country that rewards preparation and map study.
