Unit 66

Lander

Foothill pronghorn country along the Wind River Reservation boundary with scattered water and moderate access.

Hunter's Brief

Unit 66 is open, rolling sagebrush and grassland terrain in the foothills between US 287 and Wyoming 135, bordering the Wind River Reservation. Elevation stays modest—mostly between 5,000 and 7,200 feet—with sparse timber and limited water making strategic spring and reservoir locations critical. Multiple irrigation ditches and scattered reservoirs provide some water, but reliable sources are the exception. Roads provide fair access throughout; most hunters can reach staging areas near Lander or Milford with straightforward logistics.

Terrain Deep Dive

Landmarks & Navigation

The ridgelines—Blue Ridge, Cedar Ridge, McTurk Ridge, and Del Monte Ridge—provide useful glassing vantage points and natural terrain division. Ninemile Hill, Monument Butte, and Dishpan Butte serve as landscape anchors visible from distance. The major drainages including Popo Agie Creek, Dickinson Creek, and Willow Creek run through draws and valleys that concentrate animal movement and offer water access.

Rocky Draw, Ninemile Draw, and Big Sand Draw are the significant features breaking up the more monotonous sage. These draws are worth scouting; they channel pronghorn and provide shade-hunting opportunities.

Elevation & Habitat

Terrain sits entirely in the modest elevation band between 5,000 and 7,200 feet, with median elevation around 5,600 feet. This is high plains transitioning to low foothills—sagebrush grassland with scattered juniper and small draws rather than forested slopes. The sparse forest badge reflects the open character; expect rolling sage flats broken by gentle ridges and shallow valleys.

Vegetation changes subtly with elevation but never becomes thick timber. The landscape is what pronghorn country looks like: visibility is the defining feature, with open sight lines across much of the unit.

Access & Pressure

Fair access throughout—315 miles of roads provide reasonable connectivity without making the unit feel crowded or developed. US 287 and Wyoming 135 frame the boundary and offer access from Lander (the nearest substantial town). Road density doesn't overwhelm, meaning hunters can reach good country without fighting traffic. The Lander Valley draws predictable pressure, but the unit's open character and pronghorn focus means dedicated hunters can find quiet country by moving away from main drainages and ridge systems.

Early-season crowds usually concentrate near known water; mid-season often sees lighter pressure.

Boundaries & Context

Unit 66 sits in the Lander Valley foothills, bounded on the north by the Wind River Reservation (accessible via US 287 and Wyoming 135), with the eastern and southern perimeter framed by those same highways. The unit encompasses moderate acreage of open foothill country that transitions from the valley floor upward toward the reservation boundary. This is working ranch and sage country—the landscape between Lander and the Wind Rivers rather than wilderness.

Kotey Place, Milford, and Wyopo provide geographic reference points; the valley setting keeps terrain relatively straightforward for navigation.

Water & Drainages

Water is limited but present in specific locations. Popo Agie Creek is the main drainage, but irrigation ditches (Grant Young, Taylor, Samuel P Large, and others) indicate developed water infrastructure that reduces natural spring dependence. Key reservoirs include Lander Valley Reservoir, Chugwater Reservoir, and Ninemile Reservoir—all worth locating on the map before hunting.

Springs like Bain Spring, Coal Mine Spring, and Wagon Bed Spring exist but scattered widely; don't assume water is readily available. The limited water badge is accurate; planning water access before the hunt beats discovering you're thirsty mid-day.

Hunting Strategy

This is pronghorn country, period. The open terrain and sparse timber favor glassing and stalking—the classic high plains antelope approach. Early season (September) means pronghorn are dispersed across the sage; focus on small bachelor bands and does moving toward water in cooler mornings.

Rut activity (mid-September through early October) concentrates bucks; the ridges and open flats become staging areas where competing bucks claim territory. Late season (October) finds animals moving toward reliable water and sheltered draws. The draws are critical—they concentrate animals, provide screening for stalks, and offer shade.

Water sources (reservoirs and springs) should anchor your scouting; pronghorn patterns follow water availability in this drier country.
