Unit 111
Chalk Bluffs
High-plains grassland straddling the Wyoming-Nebraska border with scattered bluffs and irrigation infrastructure.
Hunter's Brief
Unit 111 is open, rolling high-plains country dominated by grassland and sagebrush across the Wyoming-Nebraska border region. The terrain is straightforward and relatively flat, making navigation simple and glassing productive. Multiple small reservoirs and creeks provide scattered water sources, though availability can be seasonal. Road access is well-distributed throughout the unit, creating logical entry points from Interstate 80 corridor towns. Pronghorn hunting here relies on glassing open country and managing distance across exposed terrain.

Terrain Deep Dive
Landmarks & Navigation
Pine Bluffs and Chalk Bluffs provide visible terrain anchors for orientation and serve as vantage points for glassing adjacent country. Spring Creek, North Fork Muddy Creek, and Duck Creek form the primary drainages crossing the unit, offering water access and natural travel corridors. Multiple small reservoirs including Beaver Dam, Campstool, and Gardner provide supplemental water sources, though most are tied to ranch operations.
Terry Peak and the Porter Draw system give hunters reference points in otherwise subtle terrain. These features are critical for navigation in country that appears uniform from ground level.
Elevation & Habitat
The unit occupies medium-elevation high plains ranging through the 5,000 to 6,500-foot band. Vegetation is predominantly grassland and sagebrush with minimal forest cover, creating open country ideal for spotting game from distance. The landscape transitions gently across rolling terrain without significant elevation breaks.
Scattered cottonwood draws and creek bottoms provide slight topographic relief and occasional vegetation density. Dry periods can stress vegetation, but spring snowmelt feeds creeks and supports grass growth. The open nature means minimal concealment—hunters rely on glassing and stalking across exposed ground.
Access & Pressure
Over 750 miles of roads create a well-connected network throughout the unit, enabling straightforward vehicle access from multiple entry points. Interstate 80 provides the primary corridor, with access to Laramie and other Front Range communities. The connected road system means hunting pressure distributes relatively evenly, though most hunters concentrate near convenient parking and major drainages.
Limited public land creates a patchwork pattern—knowledge of public-private boundaries is essential. The low terrain complexity and open country mean successful hunting often comes down to glassing efficiency and willingness to cover distance rather than finding untouched ground.
Boundaries & Context
Unit 111 encompasses the high-plains country along Wyoming's eastern border, bounded by Interstate 80 to the north, Interstate 25 to the west, and the Wyoming-Nebraska and Wyoming-Colorado state lines forming the eastern and southern edges. The unit sits at the convergence of three states where Nebraska, Colorado, and Wyoming meet. This is ranch and agricultural country interspersed with public land, positioned between the Front Range and the High Plains.
The surrounding region includes established towns along the I-80 corridor providing staging areas and supplies.
Water & Drainages
Water is limited but present in scattered sources. Spring Creek and its tributaries flow across the northern portions, while North Fork Muddy Creek and Duck Creek provide drainage systems in the southern and central areas. A network of small reservoirs—Beaver Dam, Campstool, Gardner, Culek, and others—supplement natural water, though many are private or seasonally reliable.
Several irrigation ditches including Beaver Dam Ditch and Kingman Ditch reflect the agricultural use of available moisture. Early-season hunting may depend on spring-fed sources; by mid-summer, major creeks may run low. Locating livestock water and minor seeps becomes critical in dry periods.
Hunting Strategy
Unit 111 is pronghorn country. The open, rolling grassland habitat is ideal pronghorn terrain—they thrive in the sagebrush steppe and grassland environment. Success depends entirely on glassing skills and patience; cover is minimal, so spotting animals before they spot you is paramount.
Early morning and late-day glassing from high points along the bluffs or ridges provides the best opportunity. Once located, pronghorn require careful stalking in open terrain where distance is deceptive and wind matters critically. Spring hunting favors water sources where animals concentrate.
Late-summer pronghorn are more dispersed but predictable near reliable creeks and seeps. The straightforward terrain means physical fitness matters less than optics, patience, and an understanding of pronghorn behavior in wide-open country.
