Unit 117

Star Butte, Inyan Kara Mountain, and the Cedar Ridge system provide reliable orientation points visible across the flats. The ridges—Piney, Riflepit, Elkhorn, Williams, Cedar—form the primary terrain structure, running roughly north-south and creating natural routing corridors. Springs scattered throughout (Bear Den, Buckley, State Line, Salt) mark water sources and possible glassing vantage points.

Major drainages like Poison Creek, Spring Creek, and the various canyons (Fish, Berry, Crane, Horse) funnel game movement and offer travel routes through cover. These features create a navigable landscape where terrain reading is straightforward.

The entire unit operates in the 3,500 to 6,600-foot band—pure lower-elevation country without high peaks or alpine zones. Ponderosa pine dominates forested sections, interspersed with open prairie, grassland flats, and scattered juniper. Antelope Flats and Black Flats live up to their names as expansive, rolling grasslands where visibility extends for miles.

The forest coverage feels moderate overall: thick enough in drainages and ridge systems to provide cover and travel corridors, but open enough that glassing productive. This elevation band stays mild through hunting season, though early snow can arrive at the higher divides like Elkhorn and Williams Divide.

Over 700 miles of road thread through the unit, creating a fair access network without the density that triggers severe pressure. Multiple communities (Newcastle, Jerome, Buckhorn, Osage, Clay Spur) mean multiple staging areas and entry points. The Moskee Road, Sand Creek Road, and various two-track routes provide practical access to different sections.

Most hunting pressure concentrates near road corridors and established camping areas near Newcastle. The moderate terrain complexity and expansive grassland visibility work both ways—you can see other hunters, but you can also locate distant country with fewer people. Midweek hunting and pushing into the rougher ridge drainages yields better solitude.

Unit 117 occupies the northeastern Wyoming border country, anchored by Interstate 90 at the Wyoming-South Dakota line and the Black Hills National Forest boundary to the northeast. Newcastle, Cambria, and surrounding communities provide the main access points. The unit encompasses roughly the footprint between Piney Ridge to the west and the state line to the east, with the Moskee Road corridor forming a natural southern reference.

This is true front-country terrain—no wilderness designation, but plenty of public land mixed with private holdings that define hunting strategy. The Black Hills proximity brings cooler conditions and reliable timber cover compared to typical high plains units.

Water defines strategy here. Poison Creek, Spring Creek, and Red Canyon Creek represent the primary flowing water; everything else relies on reservoirs and springs. Multiple small impoundments—C B, Y T, Kellogg, Big Delaney, Bernard Howell, Clark—dot the unit, typically near ranches or developed areas.

Springs like Bear Den, Buckley, Boardinghouse, and Salt Spring provide reliable sources away from reservoirs, but water scarcity in the broader landscape concentrates wildlife movement. Understanding which sources hold water through the season versus which go dry is critical. Seasonal timing affects water reliability—early season springs may be more dependable than late-season creeks.

Elk are the primary species, utilizing the forested ridge systems and higher drainage bottoms for cover while moving to grassland parks and flats for feeding. Early season finds elk in ponderosa timber and along the divides (Elkhorn, Williams, Cedar Ridge). Rut hunting focuses on ridge systems and the drainages connecting them—particularly the canyons and draws where bulls concentrate. Water becomes critical, especially in the drier western portions; hunting near reliable springs and reservoirs in late season concentrates opportunities.

The moderate elevation means minimal elevation migration—elk shift between timber and grass seasonally rather than moving dramatically upslope. Glassing Antelope and Black Flats in early morning and late afternoon can locate feeding herds before working into adjacent timber.
