Unit 11

Green River

High-country alpine and subalpine terrain spanning the Continental Divide with glaciers, tundra parks, and remote passes.

Hunter's Brief

Unit 11 sits along Wyoming's Continental Divide, featuring rugged alpine and subalpine terrain from roughly 7,600 to nearly 14,000 feet. The landscape transitions from forested lower slopes to open tundra parks, glaciers, and exposed ridges at higher elevations. Access is limited to seasonal roads and foot travel—this is backcountry country requiring solid navigation skills and physical conditioning. Multiple passes and drainages provide travel corridors, though weather and terrain difficulty make this a complex, remote unit best suited for experienced hunters comfortable with high-elevation conditions.

Terrain Deep Dive

Landmarks & Navigation

The Continental Divide itself forms the unit's primary navigational spine, marked by distinct summits including Brimstone Mountain, Battleship Mountain, and Split Mountain visible from multiple drainages. Multiple high passes—Gunsight, Vista, Glacier, Green River, and Bonney—provide critical terrain anchors and route corridors. Lower in the unit, Clear Creek Natural Bridge and the series of glaciers (Twins, Stroud, Sourdough, Mammoth) offer distinctive landmarks for orientation.

The tundra parks and named ridges provide valuable glassing vantage points, while the glacier systems mark the most remote, exposed portions of the unit.

Elevation & Habitat

The terrain rises from approximately 7,600 feet in lower creek bottoms to above 13,800 feet at summits like Granite Peak and Stroud Peak. Most of the unit sits above 9,500 feet, transitioning through subalpine forest with scattered whitebark pine and spruce-fir stands into expansive alpine tundra meadows and exposed ridges. The higher parks—Alexander, Loomis, Ryan, and Three Forks—offer open glassing country broken by rocky outcrops and occasional draws.

Lower drainages retain more forest cover, while the spine of the divide features bare ridges, talus slopes, and diminishing vegetation as elevation increases.

Access & Pressure

Road access totals roughly 258 miles of forest service roads, but most are seasonal and limited to lower unit boundaries and staging areas. The Union Pass Road and Darwin Ranch Road provide the primary vehicle access corridors; beyond these, travel is foot-only through high passes and open country. This remoteness and complexity create genuine solitude—most pressure concentrates at trailheads and lower creek bottoms.

The high-country terrain itself limits casual access; reaching prime alpine terrain requires hiking 5+ miles from nearest roads, which filters out all but committed hunters. Terrain complexity at 9.1/10 reinforces this as serious backcountry.

Boundaries & Context

Unit 11 occupies a substantial portion of the southern Wind River Range along the Continental Divide, bounded by the Union Pass Road to the north, the Bridger-Teton National Forest boundary to the west, and drainages separating the Green River and Gros Ventre watersheds to the east and south. The unit encompasses the headwaters country between the New Fork and Green River systems, sitting in the heart of federally managed high country with limited private inholdings. This location places it in classic alpine terrain where weather, remoteness, and elevation present significant challenges and define the hunting experience.

Water & Drainages

Perennial water is scattered and elevation-dependent. Named streams including Clear Creek, Roaring Fork, Tepee Creek, and Whiskey Creek provide reliable flow in lower drainages, while higher elevations depend on seasonal snowmelt and scattered lakes like Iceberg Lake, Horseshoe Lake, and the Seven Lakes complex. Summit Lake and other small reservoirs in the lower portions offer reliable water sources.

Alpine springs including Fish Bowl Spring and Warm Spring provide scattered options, though availability decreases significantly above timberline. Most high-elevation glassing and travel requires planning water carries between established sources.

Hunting Strategy

Unit 11 is designated for wolf hunting, and the terrain supports this specialized pursuit. The high-country parks and open ridges provide excellent for glassing across broad country and spotting movement. The Continental Divide and associated drainages funnel wildlife movement, making ridge systems and pass zones critical vantage points.

Early season often provides the best weather and highest likelihood of encountering animals at higher elevations before snow pushes activity lower. Late season winter hunting requires avalanche awareness and technical mountain skills. Success hinges on patience, glassing discipline, understanding drainage movement patterns, and physical capability to cover 8-12 miles daily at elevation in variable conditions.
