Unit 83

Legend Rocks and Minnesela Slope provide distinctive visual anchors across the lower country. The Washakie Needles formation rises prominently in the central unit, offering both navigation reference and glassing vantage. Blue Ridge and Cedar Ridge form natural travel corridors running north-south.

Boysen Ridge to the south helps orient hunters in the basin country. Twin Buttes and Round Top Mountain are recognizable peaks for distance navigation. Key drainages include Owl Creek and its multiple forks, which funnel game movement and provide navigation routes through otherwise featureless terrain.

The Holy City formation near Hamilton Dome creates a unique geographic reference in the eastern portion.

Elevation spans from approximately 4,100 feet in low basins to over 12,400 feet on higher peaks, though most huntable terrain clusters in the 5,000 to 8,000-foot range. Lower elevations feature open sagebrush plains and basin floors with minimal tree cover—ideal pronghorn country. Mid-elevations introduce scattered juniper and low conifers, creating a transitional zone where ponderosa and Douglas fir begin to appear on north-facing slopes.

Higher ridges and benches support denser timber patches, though forest coverage remains sparse throughout. The high-desert climate creates distinct seasonal transitions; lower basins dry quickly in summer while higher areas retain moisture longer.

Approximately 461 miles of roads traverse the unit, but road density is low given the vast area, creating significant navigation challenges and genuine opportunity for solitude. Most roads are ranch roads with limited public access—verification with landowners is essential. Wyoming Highways 120 and 431 provide main access routes; Highway 120 approaches from the west near Thermopolis, Highway 431 from the north.

Small communities like Thermopolis, Embar, and Kirby serve as staging points. The terrain's complexity and limited road network naturally limit hunter pressure, but understanding ownership boundaries is critical. Private ranch lands complicate access patterns significantly, particularly near lowland basins where water makes ranching viable.

Unit 83 straddles the boundary between Hot Springs County and the Wind River Reservation in north-central Wyoming, anchored by Thermopolis to the west. The unit's boundaries follow Wyoming Highways 120 and 431, with the Bighorn River forming the eastern limit and the reservation boundary running south and west. The unit encompasses roughly 1,800 square miles of high-desert country, though exact acreage is complicated by mixed ownership including non-Indian fee lands within reservation boundaries.

Access corridors follow the major highways and a scattered network of ranch roads. The landscape transitions from sagebrush-dominated basins to sparse-timbered ridges as elevation changes.

Water is the defining constraint in Unit 83. Perennial streams are limited—Owl Creek and its forks are the most reliable sources, though access varies by season and ownership. Scattered springs like Val Day Spring, Keg Spring, and the notable Maytag Spring exist but require knowledge of exact locations. Multiple reservoirs dot the unit: Grass Creek reservoirs, Wales, Wortham, and others—many associated with irrigation infrastructure on ranch lands.

Hunters must research water availability before entering, as dry camps are common. Creeks like Cherry Creek, Fall Creek, and Rattlesnake Creek may be seasonal. Understanding the canal system (Holland Ditch, South Side Ditch, Peterson Ditch) helps identify where water exists and access restrictions may apply.

Unit 83 is pronghorn-focused hunting across high-desert basin and ridge country. The sparse forest cover means pronghorn have excellent visibility—hunting relies on early-morning glassing from ridges and benches to locate animals in open basins, then planning stalks using terrain irregularities and gullies for cover. Water sources concentrate game; hunting near reservoirs and springs during dry periods can be productive.

The vast terrain demands extensive scouting before the season; identifying water and animal sign ahead of time is essential. Early season finds pronghorn in higher, cooler elevations; pressure and heat push them to lower basins later. Navigation skills matter here—terrain complexity means getting turned around is easy.

Successful hunting requires pre-season reconnaissance and acceptance that this country demands time investment.
