Unit 27

Robertson Flat and the Red Hills provide visual references across the open country for navigation and orientation. Rochelle Hills offer modest elevation gain for glassing operations and landmark identification. The Cheyenne River serves as the northern boundary and a major hydrologic feature.

Key creeks including Meadow Creek, Porcupine Creek, and the Wagonhound drainage provide both navigation corridors and water sources. Gray Butte and Black Butte, while modest summits, stand out in the plains landscape and assist with route planning.

The entire unit falls within a narrow 1,100-foot elevation band, all below 5,300 feet, making this consistently low-elevation high plains country. Sparse timber appears in scattered patches—ponderosa stands on north-facing slopes and juniper in draws—but sagebrush dominates the open flats and ridges. The habitat is predominantly non-forested plains broken by shallow valleys.

This open character defines hunting strategy; visibility and thermals are paramount. The elevation consistency means habitat remains relatively stable across seasons, though spring water sources become critical in late summer.

Limited road access keeps pressure relatively low across the unit. The Lynch Road, Dull Center Road, and Rochelle Hills Road (Forest Service Road 933) are primary access routes, most connecting to county roads rather than maintained highways. This network is sparse—roughly 230 miles of roads across a vast unit—meaning access is concentrated and predictable.

Most hunting occurs along drainages and creek bottoms accessible from these corridors. The limited infrastructure keeps casual hunters out but rewards those willing to park and walk, particularly into the draws where pronghorn congregate.

Unit 27 encompasses the high plains region between Wyoming Highways 59 and 450, bounded on the north by the Cheyenne River and on the east by the Lynch Road. The unit straddles Converse and Weston counties in northeastern Wyoming, a landscape defined by gentle rolling terrain rather than mountains. Rochelle Hills provides a modest topographic break in otherwise consistent plains country.

The terrain transitions through draws and creek bottoms that dissect the otherwise uniform sagebrush expanse, creating natural corridors for wildlife movement.

Water is the limiting resource in Unit 27. The Cheyenne River forms the northern boundary with reliable flow, while the Dry Fork provides perennial water in its drainage. Scattered reservoirs—Porcupine, Beckwith, Reno, Morton, and others—concentrate water and wildlife, especially critical during late summer. Creeks including Meadow, Porcupine, Sheep, and Spring Creek provide seasonal flow.

Hans Spring and Red Spring offer supplemental sources. Most water requires specific location knowledge; surface availability should be confirmed before hunting in mid-to-late season when flows diminish.

Unit 27 is pronghorn country in its purest form. The open sagebrush plains demand spot-and-stalk hunting; find water sources and high ridges for glassing at dawn and dusk when pronghorn are active. The draws, particularly those draining toward creeks and reservoirs, concentrate animals seasonally.

Early season offers the most visibility as vegetation remains low. Plan water access beforehand—rely on mapped creeks and reservoirs rather than assuming surface water. The sparse timber provides occasional cover but shouldn't define your approach; instead, use terrain undulation and draw systems for approach routes.

Pressure is light, allowing thorough coverage of promising country without competing with other hunters.
