Unit 25
Ormsby
High plains sagebrush country spanning Casper to Pine Ridge with limited water and sparse access.
Hunter's Brief
Unit 25 is expansive high-plains terrain between Casper and Pine Ridge, dominated by rolling sagebrush flats with sparse juniper. Elevation varies modestly between 4,800 and 6,300 feet across relatively straightforward topography. Access is limited with 338 miles of roads but low density, making interior country quieter. Water is scattered and seasonal—rely on reservoirs and stock ponds rather than flowing streams. Pronghorn is the primary quarry here; this country suits glassing tactics from high points and patience in basin country.

Terrain Deep Dive
Landmarks & Navigation
Pine Ridge dominates the northern horizon and serves as both a navigational reference and elevation highpoint. Teapot Rock and Castle Rock provide recognizable summits for glassing and orientation. Suicide Soda Lake and Pratts Soda Lakes mark water features in the open country, valuable for both locating animals and planning water strategy.
The Sand Creek system, flowing from west to east through the unit, provides the primary drainage corridor and guides navigation. McKenzie Flat offers expansive glassing country. These features are scattered enough that navigation relies on map work and bearing—expect to move methodically rather than follow obvious terrain.
Elevation & Habitat
Terrain here sits entirely in the 4,800 to 6,300-foot band—relatively modest elevation that translates to consistent high-plains sagebrush habitat. The landscape is predominantly open country with scattered juniper breaks, particularly toward Pine Ridge. Most of the unit is rolling to gently sloping terrain with few dramatic elevation changes; you're looking at basin-and-ridge country rather than steep mountainside.
The sparse forest badge reflects extensive sagebrush steppe broken by occasional juniper stands and cottonwood draws along drainage bottoms. This is classic pronghorn and mule deer terrain—big open country with distant views.
Access & Pressure
Three hundred thirty-eight miles of roads sounds substantial but spread across vast terrain yields low density. Access is genuinely limited—this is backroad country without the major highways that would push crowds. Most hunters focus on areas near boundaries and recognizable access points, leaving interior basins and ridges quieter.
Main entry routes follow Highway 387 from the north and Highway 95 from the southeast, plus ranch roads and two-tracks from Casper side. High plains terrain doesn't concentrate pressure the way canyons do; animals have room to move. The limited access works both ways: solitude is possible, but so is the need to cover country on foot.
Boundaries & Context
Unit 25 encompasses the country north and east of Casper, bounded by Interstate 25 to the west and Wyoming Highway 387 to the north. The North Platte River forms part of the western border, while Pine Ridge rises along the northeastern boundary. Sand Creek and its tributary system drain the unit southeastward, with Highway 95 defining the southeastern edge.
The unit sprawls across roughly 1,000 square miles of high plains between the Casper metro area and the rougher terrain toward the Powder River Basin. Several small towns (Edgerton, Rolling Hills) dot the boundaries, but the interior remains sparsely populated.
Water & Drainages
Water is the limiting factor here. Sand Creek and its west fork system provide the main perennial water, but flow varies seasonally and much of the unit relies on scattered reservoirs and stock ponds—V-One, V-Two, Meadow Creek, and several others. Mud Springs and Sand Springs are potential water sources but reliability isn't guaranteed during dry periods.
The North Platte River marks the western boundary but may not be accessible from much of the unit. Most hunting strategy revolves around locating animals near reliable water features or planning camp logistics carefully. Expect dry country—scout water before committing to a hunting area.
Hunting Strategy
Pronghorn is the primary draw—this is textbook antelope country. Spend time glassing from high points like Teapot Rock or ridges overlooking basins; pronghorn are visible at distance in open sagebrush. Early and late seasons allow hunting water sources near reservoirs and stock ponds where animals concentrate.
Mid-season requires more movement and aggressive stalking across open country. The sparse timber and juniper breaks offer limited cover but also mean animals are visible from considerable distance. Water strategy is critical; locate reliable sources and hunt near them.
Mule deer inhabit the unit but occupy brushy draws and juniper stands rather than open flats. Terrain complexity is straightforward but the vast, open character demands good optics, patience, and willingness to cover distance on foot.
