Unit 9

Sierra Madre

High-elevation sagebrush plateaus and rimrock country defining Wyoming's remote south-central uplands.

Hunter's Brief

Unit 9 spreads across a vast, high-elevation landscape of open sagebrush parks, scattered timber, and dramatic rimrock formations. The terrain ranges from rolling plateaus to steep-sided valleys, with elevations spanning from mid-elevation basins to alpine ridges. Access is limited but traceable via a network of rough roads and old ranch infrastructure. Water is scattered through the unit via springs, creeks, and reservoirs, requiring knowledge of reliable sources. This is big country that rewards preparation and self-sufficiency—solitude is achievable for hunters willing to work for it.

Terrain Deep Dive

Landmarks & Navigation

Atlantic Rim and Cottonwood Rim define the unit's western character, providing elevated vantage points for glassing the vast basins below. The Sierra Madre range anchors the southern portion, with summits like Bridger Peak and Mowry Peak offering navigation reference points. Bridger Pass and Battle Pass serve as natural travel corridors through higher terrain.

The Sand Hills and Savage Hills provide rolling terrain breaks across the middle country. Springs are scattered throughout—Big Spring, Beckman Spring, and Stage Station Springs mark reliable water and traditional travel routes. Basins like Reader Basin, Eightmile Lake Basin, and Wild Horse Basin offer distinct geographic divisions for breaking up the landscape mentally.

Elevation & Habitat

The unit sprawls across a diverse elevation range, with terrain climbing from mid-elevation sagebrush flats into high-country plateaus and scattered conifer stands. Lower elevations feature extensive sagebrush parks and open terrain, while higher ridges support ponderosa and limber pine scattered across otherwise open country. Expansive meadows like Huston Park, Cunningham Park, and Fletcher Park punctuate the landscape, creating natural movement corridors for wildlife.

The terrain is fundamentally open with timber serving as accent rather than dominance—typical of high-desert transition zones where trees cling to north slopes and drainage bottoms.

Access & Pressure

The unit contains over 1,100 miles of roads, primarily rough ranch tracks and old forest service routes. Access is decidedly limited despite road mileage because these roads are dispersed across vast terrain and many are gated or seasonal. Highway 789, 130, and 230 provide highway access around unit perimeter, but interior penetration requires four-wheel drive and patience.

The remoteness means relatively light hunting pressure compared to more accessible units, but this is offset by the terrain's demands. Most hunters concentrate near established trailheads and accessible drainages; the open interior remains lightly pressured for those willing to navigate rough roads and hike away from vehicles.

Boundaries & Context

Unit 9 occupies south-central Wyoming between the Colorado border and Interstate 80, bounded by Highway 789 on the west, Highway 130 on the east, and Highway 230 on the north. The unit encompasses the upper drainages of the Sierra Madre and surrounding plateaus, anchored by the small towns of Encampment and Savery. This vast expanse sits at the intersection of high-desert basins and forested ridges, characteristic of Wyoming's remote interior.

The terrain is largely roadless in its interior, with access concentrated along established but rough ranch and forest roads.

Water & Drainages

Water is the limiting factor in this unit. Perennial streams include Cottonwood Creek, Savery Creek, and Battle Creek drainages, but flow is modest and seasonal. Eightmile Lake, Miller Hill Lake, and Battle Lake provide reliable surface water, though scattered and requiring navigation.

Numerous reservoirs dot the landscape—Johnston Number 2, Sage Creek Reservoir, Jack Creek Reservoir—most serving historical irrigation purposes with variable reliability. Springs like Pop Springs, Chicken Pete Spring, and Rock Springs are critical waypoints for hunters; their exact location and seasonal flow demand local knowledge. Early-season and late-season water scarcity dictates movement patterns and camp placement strategy.

Hunting Strategy

This unit historically holds black bear in the timbered ridges and canyon drainages, particularly around the Sierra Madre and higher elevation meadows. Bears use sagebrush parks for spring grazing, concentrate in berry patches during mid-summer at higher elevations, and move to aspen draws and timber for fall forage. The sparse forest means glassing opportunities exist across open terrain—glass the benches above drainages and rim systems for movement.

Early season targets bears feeding in high parks and on green-up. Late season focuses on oak brush and remaining berry patches at mid-elevations. Water sources and travel corridors between elevation zones drive routing decisions.

Success requires multiple camp moves and extensive hiking; this is not drive-and-hunt country.
