Unit 7-A

Open prairie grasslands with scattered buttes and limited water across southwestern North Dakota.

Hunter's Brief

This is straightforward prairie country—mostly flat to gently rolling grassland with minimal timber. The unit sprawls across 1,273 square miles of private rangeland with sparse public access, requiring permission for most hunting. Water is limited to scattered springs and creeks; planning around reliable sources like the Green River and Spring Creek is essential. Well-developed road network makes navigation simple, though terrain complexity is minimal. Pronghorn is the primary opportunity here—open sightlines and low elevation make glassing-and-stalking the core strategy.

Terrain Deep Dive

Landmarks & Navigation

The Little Badlands dominate the unit's character, anchoring the central landscape with low butte ridges useful for orientation and glassing. White Butte, Black Butte, and Flagstaff Butte are the most recognizable summits for navigation. The Green River and Spring Creek represent the most reliable water corridors, cutting northward through the unit and defining major drainage systems.

Dobson Buttes and Lime Hills provide secondary topographic features for reference points. These modest features offer enough definition to break up the prairie monotony without creating significant terrain complexity.

Elevation & Habitat

The entire unit sits below 5,000 feet, ranging from roughly 2,160 to 3,040 feet elevation. This is shortgrass prairie and mixed-grass rangeland—open, treeless country ideal for long-distance visibility. The Little Badlands provide subtle topographic breaks with low buttes and ridges scattered throughout, offering slight elevation relief and natural travel corridors.

Vegetation is predominantly grassland with minimal forest cover; scattered juniper and cottonwood occur only in drainage bottoms and around water sources. The landscape is working cattle and sheep country with native prairie—big, exposed, and simple to read.

Access & Pressure

The unit is nearly 97 percent private land, making access the defining constraint. A well-developed road network (nearly 2,500 miles of roads at 1.97 mi/sq mi density) means finding your way is straightforward, but legal access requires permission from private landowners. Several highways including major routes near Dickinson cross the unit, providing approach routes but also potential highway hunting pressure near accessible areas.

Most hunters will be concentrated near major roads and town-adjacent sections. The vast majority of the unit remains lightly hunted simply due to access barriers, not because of difficult terrain.

Boundaries & Context

Unit 7-A occupies a large swath of southwestern North Dakota between Dickinson and the Wyoming border, centered on the Little Badlands region. The unit is nearly 1,273 square miles of predominantly private rangeland with minimal public acreage—a critical consideration for access planning. Several small towns including Dickinson, South Heart, and Regent sit on or near the unit boundaries, providing supply and staging points.

The terrain is geographically simple: grassland prairie with subtle elevation changes and scattered badlands features. This is low, open country dominated by private working ranches.

Water & Drainages

Water is the unit's limiting factor. The Green River flows north through the central unit and represents the most dependable year-round source. Spring Creek in the western portion and Ash Creek in the east provide secondary drainage systems with seasonal water.

Scattered springs including Black Spring and reservoirs like Jung Lake and Edward Arthur Patterson Lake supplement flow, though reliability varies seasonally. Most hunting will require knowledge of current water status; dry periods can concentrate pronghorn movement. Plan water locations carefully and have contingency sources identified before hunting.

Hunting Strategy

This is pronghorn country. The open prairie grasslands, minimal vegetation, and flat-to-rolling topography are ideal for spotting-and-stalking pronghorn across long distances. Early season offers easier glassing as vegetation is lower; fall rut periods concentrate animals.

Water sources become critical during dry periods, potentially funneling pronghorn into predictable patterns. The lack of elevation changes simplifies terrain navigation but eliminates hiding cover—stalking requires patience and use of terrain breaks provided by buttes and drainage bottoms. Access requires advance landowner permission.

Hunting pressure is generally light away from roads due to access limitations, offering opportunity to find less-pressured animals.
