Unit 3A4
Northern Coteau
Vast prairie grasslands with scattered buttes, reliable water, and a connected road network.
Hunter's Brief
This is straightforward high plains country—rolling grasslands and sagebrush flats punctuated by low buttes and coulees. The terrain is low-elevation and open with minimal timber, making glassing productive and navigation simple. Water comes primarily from lakes and reservoirs scattered throughout, with creeks in the valleys. A dense road network provides easy access, though most land is private, so public hunting requires careful planning and local knowledge. The country suits mobile hunters covering ground systematically.

Terrain Deep Dive
Landmarks & Navigation
Black Butte and Buffalo Lodge Butte serve as primary navigation and glassing landmarks, visible from miles across the flat country. Hogback Ridge runs as a recognizable terrain feature for orientation. The Henderson Hills provide a secondary ridge system worth investigating.
Coulee systems—particularly Hay Coulee, Spring Coulee, and LaPorte Coulee—funnel deer movement and offer natural corridors for hunting. These valleys concentrate vegetation and water, making them productive focus areas. The Wintering River and creeks including Oak, Miller, and Snake provide water sources and travel routes.
Elevation & Habitat
The entire unit sits in a narrow elevation band, all below 1,900 feet, creating uniform prairie habitat with minimal vertical zonation. Grasslands and sagebrush dominate the landscape, with scattered riparian timber along watercourses. Low buttes like Black Butte and Buffalo Lodge Butte rise modestly above the plain, offering vantage points but not creating distinct habitat breaks.
The open character is striking—nearly 98 percent of land cover is plains without forest, meaning long sightlines and minimal concealment. This exposes hunters but also makes spotting deer straightforward.

Start free trial ›Access & Pressure
A dense road network of 2.21 miles per square mile makes the unit highly accessible, with 845 miles of major roads and 472 miles of highway. This connected infrastructure means hunters can quickly scout and relocate, but also that pressure on accessible land concentrates near main routes. The challenge here is private land dominance—95 percent is private—which restricts where legal hunting occurs.
Public land is scattered and limited. Successful hunters will need to identify public access points or secure landowner permission. The straightforward terrain and road access mean that experienced prairie hunters can be efficient; novices may struggle finding legal ground.
Boundaries & Context
Unit 3A4 sprawls across roughly 2,700 square miles of northwestern North Dakota prairie. The flat to gently rolling landscape is defined by open grasslands interrupted by low buttes, ridges, and coulee systems. Henderson Hills and Hogback Ridge provide modest elevation breaks.
Towns including Logan, Surrey, and Forfar sit at the unit's edges, offering staging and supply stops. The unit is entirely lower elevation—all terrain sits below 1,900 feet—creating a cohesive prairie ecosystem. This is private-land-dominant country where access hinges on landowner relationships.
Water & Drainages
Multiple lakes and reservoirs punctuate the unit, including Rock Lake, Oslie Lake, Round Lake, Rush Lake, and Poison Lake, plus several management reservoirs. These water sources are critical in prairie country and concentrate deer activity, especially during dry periods. The Wintering River runs through the unit with seasonal flow, while creeks like Spring Creek, Willow Creek, and Stone Creek provide additional water in their corridors.
Belmar Slough offers seasonal water. The moderate water availability across the unit means deer movement is relatively predictable near documented sources, simplifying hunting strategy.
Hunting Strategy
Mule and white-tailed deer use this prairie country year-round, with hunting focused on the open grasslands and coulee bottoms. Early season deer remain in high country; this unit's low elevation means deer don't migrate far—hunt productive sagebrush and grassland edges adjacent to water. Rut activity concentrates near does, typically in open terrain and riparian corridors.
Late season finds deer in coulees and draws where cover and water concentrate. Glassing is effective across the open landscape. Key strategy: identify public access (limited but present), scout water sources and coulee systems for deer sign, and focus on riparian bottoms where timber and water converge.
Pressure increases near main roads, so exploring secondary access often pays dividends.
