Unit 33
Middle Fork
Sprawling sagebrush basin with isolated ridges and limited water - remote high plains hunting.
Hunter's Brief
Unit 33 is vast, open sagebrush country at lower elevations with scattered ridges breaking up the flats. Most terrain sits between 4,600 and 8,500 feet, dominated by plains with sparse timber. A limited road network makes access deliberate rather than convenient, which trades accessibility for solitude potential. Water is scarce and concentrated in reservoirs, springs, and creek bottoms - critical for locating elk. The terrain is straightforward enough to navigate but expansive enough to demand patience and glassing skill.

Terrain Deep Dive
Landmarks & Navigation
Devils Monument and Castle Rock serve as distant navigation markers visible from lower terrain. The Mesa and Tisdale Mountain provide ridgeline references. Poker Butte, Roughlock Hill, and Steamboat Rock dot the landscape as recognizable landmarks.
Red Wall and The Wall offer natural features for terrain orientation. Named drainages like Million Creek, North Poker Creek, and Lost Creek function as travel corridors and water reference points. The Trap and Bar C Gap are notable topographic breaks.
These scattered features help break up the monotony but require map work and glassing to effectively locate and use during hunting.
Elevation & Habitat
Terrain ranges from 4,600 feet in basin bottoms to 8,500 feet on ridgetops, with most country sitting in the 5,000-6,000 foot band. This is sagebrush basin country with sparse tree cover concentrated on north-facing slopes and ridge systems. Low elevation means little alpine terrain; instead, expect wide-open flats interrupted by juniper pockets and scattered ponderosa on higher ground.
Vegetation transitions from pure sagebrush in the basins to juniper-and-grass mixes on ridges and occasional conifer stands on the steeper north aspects. The openness creates visual hunting country but offers limited thermal cover.
Access & Pressure
Over 280 miles of roads crisscross the unit, but density is sparse relative to the vast terrain, meaning access is genuinely limited despite the mileage. County roads like the 33 Mile Road, Hazelton Road, and Dead Horse Road provide main access corridors, but segments are maintained unevenly and may be impassable in wet conditions. Most hunters stage from Kaycee or Barnum, creating pressure concentration near the eastern boundary and around town access points.
The western and northwestern portions see far less pressure due to distance from staging areas and rougher road conditions. The complexity score of 7 reflects the combination of expansive terrain and limited road infrastructure creating navigation challenges.
Boundaries & Context
Unit 33 occupies a large swath of north-central Wyoming, anchored by Interstate 25 on the east near Kaycee and Midwest, with boundaries extending west and north through Natrona and Washakie Counties toward the town of Barnum. The unit encompasses classic high-plains terrain where the Powder River Basin transitions from interstate corridor to remote sagebrush country. State highways 190 and 191 frame portions of the perimeter, but most access depends on county roads that become increasingly sparse the deeper you penetrate west.
The sheer size means hunters must commit to specific areas rather than casual exploration.
Water & Drainages
Water is the limiting factor in Unit 33. Reservoirs including Rock Spring, Keith, Three Forks, Chocolate, and Ellis provide reliable surface water but are often concentrated in specific locations. Perennial creeks like Million Creek, North Poker Creek, and Lost Creek maintain seasonal flow. Springs—Jacques, Taylor, Turkey, Antelope, and others—exist but may dry seasonally.
The Lea Ditch and other irrigation structures indicate developed water infrastructure. In typical dry conditions, elk concentrate near reliable water sources, making drainage systems and reservoir locations tactical elements. Early and late season especially demand water-source knowledge for elk location.
Hunting Strategy
Unit 33 holds elk that utilize both basin flats and ridge systems depending on season and pressure. Early season finds elk in higher sagebrush country and ridge timber; they migrate lower as temperatures cool and snow arrives. Rut activity centers on ridge systems where bulls can cover terrain and respond to calling.
Late season concentrates elk in the most protected south-facing draws and canyon bottoms. Success depends on locating water first, then glassing open country to spot feeding or traveling animals. The limited road network means hiking from natural staging points and establishing glassing positions overlooking known elk concentration areas.
This is methodical hunting—find water, glass from distance, plan entries that minimize disturbance.
