Unit 3E1
Slope
Open prairie and rolling grassland with scattered buttes and reliable water in central North Dakota.
Hunter's Brief
Unit 3E1 is vast, mostly treeless prairie broken by low buttes and badland formations. The terrain is straightforward—gently rolling grassland at modest elevation with good road access throughout. Water exists via streams, lakes, and reservoirs scattered across the unit. Most land is private, but roads provide reasonable access for scouting and hunting. The sparse forest cover means hunting requires glassing and stalking open country. Early season offers the most accessible conditions before winter weather impacts mobility.

Terrain Deep Dive
Landmarks & Navigation
The Little Badlands anchor the eastern portion and offer the unit's most dramatic topography—a break from relentless flatness. Scattered buttes serve as navigation points: Heart Butte, Antelope Butte, Long Butte, and Stone Hills are visible from distances and useful for glassing. Rattlesnake Point and the Frey Hills, Zich Hills, and other low ranges provide modest elevation for surveying surrounding grassland.
Lakes and reservoirs—including Charles Lake, Lake Tschida, and several others—concentrate wildlife and mark water sources. The South Branch Heart River and associated creeks like Beaver and Buffalo Creek define drainage corridors through otherwise uniform terrain.
Elevation & Habitat
Everything here sits below 5,000 feet, with terrain ranging from roughly 2,000 feet in lower drainages to just over 3,000 feet on the highest buttes. The habitat is almost entirely open grassland and prairie—no significant forest cover to speak of. Scattered buttes like Antelope, Heart, and Stone Hills rise as isolated features above the surrounding plains, but even these summits remain treeless or barely timbered.
This is pure prairie-dog and shortgrass country with occasional draws supporting denser vegetation. Habitat transitions are subtle here; the real breaks are the badland formations and coulees that provide concealment in otherwise exposed terrain.
Access & Pressure
Roads blanket the unit—1.86 miles per square mile means nearly every section has a road or two crossing through it. Most access follows county and township roads through private land; hunters need permission. Highway corridors (US routes and state highways) border and traverse the unit, making approach straightforward but also predictable.
The downside: that same connectivity means other hunters find access easy too. Pressure likely concentrates along roadsides and near towns (Dickinson, Glen Ullin, South Heart). The advantage is the unit's size—97% private land means space to spread out if you've got access. Early season typically sees lighter pressure than late season when animals concentrate near water.
Boundaries & Context
Unit 3E1 sprawls across roughly 2,000 square miles of central North Dakota prairie country between Dickinson and Glen Ullin. The unit sits in the northern Great Plains region, dominated by grassland with occasional badland breaks and scattered buttes. The landscape feels open and exposed—there are no mountain boundaries, just the continuous rolling prairie with small towns dotting the perimeter.
The unit's flat character means navigation is straightforward, though the sheer size demands planning. This is Big Sky country where you see weather coming from miles away.
Water & Drainages
Water exists but isn't abundant; it's concentrated in specific features rather than distributed evenly. The South Branch Heart River and its tributaries (North Creek, Beaver Creek, Peters Creek, Buffalo Creek, and others) form the primary drainages carrying reliable water. Multiple reservoirs and lakes—Charles Lake, Lake Tschida, Jung Lake, Edward Arthur Patterson Lake—provide seasonal and year-round water sources.
Springs like Black Spring occur but aren't numerous. For hunters, water strategy means knowing where these features lie and understanding that animals concentrate near them during dry periods. Late season can mean real pressure on these limited water sources.
Hunting Strategy
This unit holds mule deer, white-tailed deer, and whitetails across the grassland prairie. Mule deer favor the buttes and badland breaks where terrain provides escape routes and glassing opportunities. Whitetails use the creek bottoms and draws with denser cover.
Early season (September-October) offers the best conditions—animals are still patterned to summer ranges, roads are accessible, and the grassland greens up with fresh growth. Hunt the buttes for mule deer; glass from elevation and stalk into the wind. Whitetails require knowing water sources and hunting the creek drainages.
Late season concentrates deer on remaining vegetation and near water, but winter weather can shut down access. The flat, open character means success depends on good optics, patience with glassing, and securing access permission.
