WY Pronghorn Unit 107 — Upper Sweetwater

WY 107 – Upper Sweetwater. Terrain & Access Upper Sweetwater spans nearly 196,000 acres across a rugged elevation band from 7,231 to 12,433 feet, with exceptional public-land access—97.3% of the unit is public. This high-elevation terrain limits pronghorn habitat to the lower benches and valleys, making concentrated glassing a practical strategy on accessible ridges and open slopes. Herd Quality Recent wildlife surveys show a buck:doe ratio averaging 55:100—exceptional and well above the 35:100 threshold that marks outstanding pronghorn populations. This ratio indicates a mature age structure with abundant mature bucks, ideal conditions for hunters pursuing quality animals..
