Unit 126
Lost Springs
High plains and badland breaks spanning three northeastern counties with scattered buttes and limited water.
Hunter's Brief
Unit 126 covers a massive swath of northeastern Wyoming's high plains country—rolling sagebrush flats punctuated by scattered buttes, ridges, and badland breaks. The terrain sits between 3,500 and 5,800 feet with sparse timber and wide-open vistas. Access is limited with minimal improved roads, making much of this unit feel remote despite its size. Water is scarce and seasonal, requiring hunters to focus effort near known springs and reservoirs. This is big country that rewards patience and self-sufficiency.

Terrain Deep Dive
Landmarks & Navigation
Navigation hinges on recognizing scattered buttes and ridge systems visible across the plains. Steamboat Rock, Castle Rock, Hat Rock, and Ship Rock serve as distant landmarks useful for glassing and orientation. The Old Woman Creek Hills, Horseshoe Hills, and various smaller ridge systems break the monotony and create hunting terrain.
Notable draws and flats—including Sundquist Flats, Culligans Flats, and several named gulches—help subdivide the vast country into huntable sections. Coyote Gap and Twentyone Divide offer natural travel corridors. These features are essential for navigation given the limited road network and need to locate water sources.
Elevation & Habitat
This entire unit sits in the 3,500 to 5,800-foot band—genuine high plains country without significant alpine terrain. The landscape is predominantly open sagebrush and grassland with scattered juniper and cottonwood in drainages. Elk historically use this country during specific seasons, moving between the higher mountains to the west and these lower plains.
The terrain transitions between flat tableaus and broken badland country with intermittent timbered draws. Vegetation is sparse overall, dominated by sage and native grasses with riparian zones providing the only reliable cover and forage concentration points.
Access & Pressure
Despite 2,200 miles of roads totaling across the unit, most are ranch roads and unimproved tracks—the road density doesn't translate to hunting accessibility. Limited highway access and sparse development mean hunter pressure is generally lighter than adjacent units, but the vast size also means finding concentrated elk requires serious effort. Small towns like Van Tassell, Douglas, and Morrisey serve as the nearest resupply points.
Four-wheel drive is often necessary for exploring the backroad network. The scarcity of improved access actually creates opportunity for patient hunters willing to navigate rough country and locate water sources away from main travel routes.
Boundaries & Context
Unit 126 encompasses all of Converse, Weston, and Niobrara counties plus the Belle Fourche River drainage in Campbell County—a vast stretch of northeastern Wyoming's high plains. The unit sprawls across three counties and multiple drainages, creating a complex geographic area that spans from the settled areas near Douglas and Van Tassell eastward to remote badland country. Its size and boundary complexity mean hunters need solid navigation skills and detailed maps.
The Belle Fourche River forms a natural eastern reference point, while the surrounding county lines define the core hunting territory.
Water & Drainages
Water is the limiting factor across Unit 126. Named creeks include Sage Creek, Duck Creek, Box Creek, Shawnee Creek, and Walker Creek, though most run seasonally or diminish significantly by late summer. Multiple reservoirs scatter across the unit—Buck Reservoir, Hornbuckle, Bear Creek Reservoir, and several others—but many are isolated from developed access. Springs are critical: Lake Spring, Kelly Spring, Mud Springs, Mix Spring, Red Rock Spring, and others provide focal points for both wildlife and hunter planning.
Success depends on pre-hunt scouting to confirm water availability and understanding seasonal flow patterns in creeks and draws.
Hunting Strategy
Unit 126 is elk country, though the open plains setting requires a different mindset than mountain hunting. Early season, bulls move onto the high plains to feed in cooler months; later they push into rougher breaks and timbered drainages for thermal cover. Success depends on understanding seasonal migration patterns and water availability.
Hunt near springs and reservoirs during dry periods. The broken badland country around the Graham Roughs, Cedar Breaks, and Hat Creek Breaks provides terrain where bulls can hide. Glassing from elevated flats and ridges is productive during low-light hours.
This unit rewards hunters who glass methodically, locate water sources, and are prepared for long hikes in open country where wind and visibility work against you.
