Wyoming Rocky Mountain Bighorn Sheep

Unit 7 (Wind River)

Wyoming Hunting Guide — Rocky Mountain Bighorn Sheep

Hunt Area 7 covers the heart of the Wind River Range — one of the most spectacular and remote bighorn sheep environments in the lower 48 states. The high granite cirques, alpine lakes, and sweeping ridgelines between Pinedale and Lander hold a strong bighorn population managed for trophy quality. Rams in the Wind Rivers carry exceptional horn mass and curl, with full-curl animals common among trophy-class bulls harvested here. The unit requires significant backcountry experience — most productive habitat is 8–15 miles from any trailhead in the Bridger and Popo Agie Wilderness areas. This is Wyoming's quintessential mountain sheep hunt.

Rocky Mountain Bighorn Sheep Hunting in Unit 7

Where to Find Bighorn Sheep in Unit 7

Bighorn sheep in Unit 7 inhabit the high alpine terrain of the Wind River Range — the granite cirques, rocky ridgelines, and alpine meadows above 9,500 feet between the Big Sandy, Green River, New Fork, and Popo Agie drainages. This is classic mountain sheep country.

High Cirques and Ridge Systems

Rams summer in the highest cirque basins above 11,000 feet — the Titcomb Basin, Big Sandy Basin, and the high country along the Continental Divide. In September and October, rams descend to ridgelines between 9,500 and 11,000 feet where grassy benches and talus mix with cliff escape terrain.

Bridger Wilderness Interior

The Bridger Wilderness interior — accessible from Big Sandy, New Fork, or Green River Lakes trailheads — holds the highest ram densities. The 10–15 mile approach filters out pressure, and sheep in this terrain see minimal human contact. Multiple ram bands often inhabit the same ridge complex.

Popo Agie and Lander Drainage

The eastern Wind Rivers accessed from Lander via the Popo Agie Wilderness provide excellent sheep habitat in slightly drier, more open terrain. The Cony Mountain and Middle Fork Popo Agie areas are key sheep zones accessible from the east side.

How to Hunt Bighorn Sheep in Unit 7

Wind River bighorn hunting is a full wilderness expedition requiring complete backcountry self-sufficiency. The rewards — world-class rams in one of North America's most stunning mountain environments — justify the preparation demands.

Expedition Planning

Plan for a 10–14 day backpack or horse-supported expedition from your chosen trailhead. Big Sandy Trailhead (south), New Fork Lakes Trailhead (northwest), and Green River Lakes Trailhead (north) are the primary access points. Horse support from licensed outfitters makes the heavy camping and potential packout manageable.

Alpine Glassing

Set up on ridgetops or prominent points overlooking multiple cirque basins with a quality spotting scope. The Wind Rivers' open alpine terrain allows glassing across large distances. Cover 2–4 miles of ridge per glassing session to locate ram bands systematically. Once rams are found, study their movements for 1–2 days before planning an approach.

High-Altitude Stalks

At 10,500–11,500 feet, physical exertion is demanding. Move slowly on stalks and allow recovery time before the final approach. Wind shifts rapidly in mountain terrain — stay downwind and use terrain features to mask your approach. Final shots on mountain sheep are often 200–400 yards across open terrain.

Apply every year without fail from your first eligible year.

Wyoming's 75/25 draw structure allocates 75% of tags to max-point applicants — once you reach the max-point tier, your draw probability improves substantially. The 25% random component gives lower-point applicants a small but real chance each year.

Unit Logistics & Expectations

Planning Notes

🚐

RV Sites

None in the wilderness. Pinedale and Lander have full-service RV parks for staging.

⛺

Camp Sites

Wilderness camping only in the Bridger and Popo Agie Wilderness areas. No developed campgrounds in the core sheep habitat. Trailhead campgrounds available at Big Sandy and Green River Lakes.

🛻

Trailer Access

Big Sandy Road handles horse trailers to Big Sandy Trailhead. Green River Lakes Road handles trailers. Some forest approach roads are rough — scout ahead.

💧

Water

Excellent. Hundreds of alpine lakes and streams throughout the Wind Rivers. Always treat — giardia is present.

🛣️

Road Conditions

Big Sandy Road and Green River Road are gravel and accessible to standard vehicles in dry conditions. Mountain approaches are all trail or cross-country.

🥾

Terrain Difficulty

Extreme. 8–15 mile approaches over high-altitude terrain to 11,000+ feet. Full mountaineering fitness required. A sheep packout in this terrain is a major undertaking.

👥

Hunting Pressure

Very low in the interior wilderness. Trailhead areas see backpacker traffic but sheep habitat is well above most foot traffic.

🌦️

Weather

September–October temperatures 5–50°F in the high country. Afternoon thunderstorms are daily in early season. October brings early winter conditions with heavy snow possible at any time. Prepare for -20°F overnight temperatures on extended expeditions.

📱

Cell Service

None. A satellite communicator (inReach or SPOT) is mandatory safety equipment in the Wind Rivers.

Nearest Town

Pinedale (west side access — full services). Lander (east side access — full services, 90 minutes from primary east-side trailheads).

Frequently Asked Questions

What trailhead should I use for Unit 7 Wind River bighorn sheep?

Big Sandy Trailhead (south) provides access to the core sheep habitat in the Big Sandy and Cirque of the Towers area. Green River Lakes Trailhead (north) accesses the northern Wind Rivers. New Fork Lakes serves the west-central range. Choose based on where WGFD surveys indicate current ram concentrations.

How many preference points do I need for Unit 7 bighorn sheep?

Non-residents should plan for 15–20 preference points. The Wind Rivers are one of Wyoming's most competitive sheep draws. Residents draw with 10–15 points on average. There is no shortcut — apply every year from your first eligible year.

Is a horse required for Unit 7 bighorn sheep?

Not required, but strongly recommended. The 8–15 mile wilderness approaches and potential 200–400 pound packout of a mature ram make horse support from a licensed outfitter highly practical. Experienced backpackers with ultralight setups can hunt DIY, but the logistics are demanding.
