Unit 103 (Great Divide Basin)

Wyoming Hunting Guide — Pronghorn

Area 103 sits inside Wyoming's Red Desert — the Great Divide Basin south of Wamsutter. It is vast, lightly pressured, and dominated by BLM ground, with historic herds that migrate hundreds of miles between the Red Desert and the Upper Green River. Hunters willing to navigate the basin's complex two-track network find legitimate 15-16 inch bucks and days where they see hundreds of pronghorn in a single glassing session.

Pronghorn Hunting in Unit 103

Area 103 sits inside Wyoming's Red Desert — the Great Divide Basin south of Wamsutter. It is vast, lightly pressured, and dominated by BLM ground, with historic herds that migrate hundreds of miles between the Red Desert and the Upper Green River. Hunters willing to navigate the basin's complex two-track network find legitimate 15-16 inch bucks and days where they see hundreds of pronghorn in a single glassing session.

Where to Find Pronghorn in Area 103

The Great Divide Basin is a rainwater-trapped bowl — pronghorn concentrate where sage, water, and wind meet.

Opening Week

Herds are still on summer patterns and scatter broadly across the basin floor. Glass the country around Chain Lakes, Lost Creek, and the Haystack Mountains for the widest distributions.

Mid-Season

Pronghorn key on the remaining stock water and the cheatgrass flush that follows early fall rain. The windmill tanks along Bar X Road and the two-tracks leading toward Adobe Town WSA hold animals through midday.

Late Season

Bucks shed and herd back up. Migration pressure pushes animals toward the Continental Divide ridges on the east and west rims of the basin. Late-season hunters focus glassing on the transition benches.

Frequently Asked Questions

Is Area 103 good for trophy pronghorn?
Yes. The Great Divide Basin has historically produced Wyoming's largest pronghorn herds, and mature 15-16 inch bucks are taken every season. Trophy potential rivals the more famous Red Desert areas to the west.
Do I need 4WD for Area 103?
Strongly recommended. The main basin roads are passable in 2WD when dry, but side two-tracks and any wet conditions require 4WD and high clearance. Gumbo mud after rain is legendary.
Are there lodging options inside the unit?
No. The closest lodging is in Wamsutter, Rawlins, or Rock Springs. Most hunters camp on BLM or stay in Rawlins and commute 1-2 hours each way.
