Unit 33

Casper Mountain

Open sagebrush and grassland interspersed with forested ridges near the North Platte River drainage.

Hunter's Brief

Unit 33 is mid-elevation country characterized by rolling plateaus and scattered mountain ridges breaking up wide-open sagebrush and grassland basins. The terrain spans from low desert valleys to forested ridge systems, offering a mix of open glassing country and timbered refuge. Access is straightforward with connected road networks linking toward Glenrock and surrounding communities. Water comes primarily from perennial creeks and scattered reservoirs rather than springs, requiring strategic water location knowledge. The moderate terrain complexity and fair accessibility create hunting opportunities across varied elevation zones without excessive pressure concentration.

Terrain Deep Dive

Landmarks & Navigation

Casper Mountain County Park and Hat Six Hogback provide dominant visual references across the rolling terrain. Deer Creek Range runs as a major north-south ridgeline offering excellent vantage points for surveying the surrounding country. Garden Creek Waterfall marks a notable drainage feature in the Deer Creek system.

Red Buttes, Pine Mountain, and Ice Cave Mountain provide recognizable summits for navigation. Steeple Pasture and Negro Creek Park represent significant meadow and park systems worth examining during transition periods. Glen Rock serves as an eastern landmark near Glenrock, anchoring the unit's populated reference points.

Major reservoirs including Evansville Storage, Mary Steed, and Nicholaysen provide both water markers and staging areas.

Elevation & Habitat

Terrain spans mid-elevation zones with low sagebrush and grassland basins dominating the lower valleys, transitioning to scattered juniper and pine-covered ridges at higher elevations. The Deer Creek Range and surrounding foothills provide ponderosa and Douglas-fir cover in steeper terrain, creating distinct habitat pockets. Upper elevation parks and benches support mixed conifer stands with openings suitable for grazing.

Meadow areas and agricultural land intersperse with native sagebrush throughout the unit. The elevation spread creates natural seasonal movement patterns with lower-elevation grazing grounds in winter and ridge systems offering refuge during summer and fall.

Access & Pressure

Extensive road networks totaling over 800 miles provide straightforward access throughout the unit, with primary routes linking toward Glenrock and surrounding communities. The connected road system reduces access difficulty but creates predictable hunting pressure patterns around maintained drainages and reservoir access points. Most hunters concentrate near Glenrock and along the primary creek corridors where water and road access converge.

Moderate terrain complexity allows pressure distribution, but popular meadow systems and reservoir areas see consistent traffic during season. Strategic hunters should focus on side drainages and upper elevation park systems away from main access routes to find quieter country.

Boundaries & Context

Unit 33 encompasses country centered around the North Platte River corridor and its major tributaries, with Glenrock serving as the primary reference point for geographic orientation. The unit stretches across rolling uplands and basin terrain typical of Wyoming's transition zone between high plains and mountain country. Deer Creek Range and Hat Six Hogback provide the major ridge systems defining the topography.

Bordered by the North Platte drainage to the south and west, the unit spreads north and east across mixed ownership country with significant connected road access. The landscape transitions from sagebrush flats to scattered conifer stands as elevation increases toward the higher ridge systems.

Water & Drainages

The North Platte River anchors the western and southern boundary as the unit's most significant perennial water source. Deer Creek system with its East and West forks provides reliable drainages running north to south through the heart of the unit, offering water access at multiple elevations. Negro Creek and Spring Creek offer secondary drainage systems with consistent flow.

Scattered reservoirs throughout the unit—including Carroll, Sage Creek, Katy, and Flaherity—provide supplementary water but with limited surface access during hunting season. Asbestos Spring, Indian Spring, and Phillips Spring mark reliable water points for hunters working high country. Summer water availability is better than late-season conditions; identifying active creeks versus seasonal drainages is critical for strategy.

Hunting Strategy

Unit 33 supports black bear, with the diverse elevation and habitat mosaic providing suitable conditions across the unit. Bears utilize the lower sagebrush and grassland country during spring and early summer, moving to higher-elevation forested ridges and parks as season progresses. Deer Creek system and its upper forks offer prime habitat combining timber cover with open feeding areas.

Late-season bears concentrate in remaining berry patches and transition zones between high parks and timber. The scattered reservoir system and reliable creeks provide water access for both glassing and stalking approaches. Early season success favors lower elevation travel corridors and creek bottoms; later hunting requires moving to ridge systems and upper parks where bears shift with changing food sources.
