Unit 11
Mule Creek
High plains country where creeks cut through sagebrush and grassland between Wyoming and South Dakota.
Hunter's Brief
Unit 11 spreads across the northeastern Wyoming high plains, a sprawling landscape of low elevation sagebrush flats and grass country punctuated by draws and creek bottoms. Mule deer and whitetails use the drainages and scattered cover throughout. Access comes via county roads and U.S. Highway 85, which bisects the unit—good connectivity but also predictable pressure corridors. Water is sparse outside creeks like Lodgepole and Stockade Beaver, making water sources critical for hunting strategy. Terrain is relatively straightforward, making this accessible country for hunters comfortable with open ground and working drainages.

Terrain Deep Dive
Landmarks & Navigation
Key landmarks include the Graham Roughs and Rattlesnake Ridge, which provide slight elevation breaks for navigation and glassing across otherwise open country. The Nose (a notable cliff feature) and Chimney Rock Butte serve as recognizable reference points. Creeks like Lodgepole and Stockade Beaver are physical landmarks hunters can follow as navigation corridors.
Draws such as Glasby Draw, Marcus Draw, and the Brewster Draws break the plains and funnel game movement. Horseshoe Bend on one of the creeks provides another identifiable feature. These landmarks are moderate in prominence—useful for orientation but not dramatic; navigation here relies more on county roads and creek systems.
Elevation & Habitat
The entire unit sits in the lower elevation band around 3,600 to 4,700 feet, creating a high plains environment dominated by sagebrush, native grasses, and scattered shrubland. Timber is minimal—mostly limited to riparian corridors along the major creeks and occasional draws. The terrain transitions gradually across rolling prairie rather than steep mountains.
Vegetation is sparse and open, typical of northeastern Wyoming's semi-arid climate where big sky country meets practical ranching ground. This open character means thermal cover is limited; deer concentrate in the creek bottoms, draws, and rare timber patches.
Access & Pressure
Over 400 miles of roads provide fair connectivity throughout the unit, with U.S. Highway 85 as the main spine and county roads providing secondary access. This creates moderate hunting pressure concentrated along primary roads and obvious creek bottoms. Hunters can reach much of the country, but sparse timber and open terrain mean anyone hunting gets visible quickly.
The straightforward terrain and road network mean there's less hiding from pressure; established access routes funnel hunters into predictable patterns. Working ranch country and private land interspersed with public ground require careful attention to boundaries. Early season pressure often concentrates near Highway 85 and obvious water sources.
Boundaries & Context
Unit 11 spans the Wyoming-South Dakota border country in Weston, Niobrara, and Converse counties, anchored by Highway 85 running north-south through its center. The unit's eastern boundary follows the state line and Highway 18, while western boundaries track county roads through rangeland and agricultural transition zones. The landscape sits in the foot-hills region between higher mountain country to the west and the plains extending eastward.
This is working ranch and public land country where old ranch roads, county roads, and highways provide the primary access infrastructure throughout the unit.
Water & Drainages
Water is the limiting resource in Unit 11. Lodgepole Creek and Stockade Beaver Creek are the primary reliable drainages, flowing year-round through the unit. Secondary creeks including South Snyder Creek, Snyder Creek, Sheep Creek, Sevenmile Creek, and Owl Creek provide seasonal water and deer habitat. Multiple small reservoirs dot the landscape (Peterson, Brenner, Spring Draw, Johnny Wasserburger, Geiger, Boggy, and others), though some are historical and may be unreliable.
Elk and mule deer concentrate around these water sources, particularly during dry periods. Without water, much of the open sagebrush flats are less attractive to game, making creek bottoms and reservoir areas primary focus areas.
Hunting Strategy
Mule deer and whitetails inhabit this unit, using the creek bottoms and draws as primary cover and daily travel corridors. Early season often finds mule deer in the open sagebrush during cooler mornings and evenings, with deer moving to creek bottoms for thermal refuge during day. Whitetails prefer the riparian corridors and brush-choked draws.
The sparse timber and open nature mean glassing the breaks and drainages is more effective than stillhunting. Water sources become critical in dry periods—hunting near Lodgepole Creek, Stockade Beaver Creek, or active reservoirs concentrates opportunity. The low elevation means early and late season hunts can track temperature-driven movement through the sagebrush.
Avoid the pressure corridors along Highway 85 by accessing via secondary county roads and working smaller, less obvious draws.
