Popo Agie Wilderness (Units 90/92)
Shoshone National Forest, Wyoming, USA
The Popo Agie Wilderness, part of the Wind River Range, is defined by its dramatic granite peaks, high-alpine lakes, and subalpine forests. This is a rugged, scenic wilderness that provides excellent habitat for mule deer willing to climb. The 'Popo Agie' is named after a Crow Indian phrase meaning 'start of the waters,' referencing the headwaters of the Popo Agie River. What makes it special is its remoteness from easy road access and the challenging terrain that keeps many hunters out. Access is primarily from trailheads west of Lander, with pack-ins of 5-15 miles needed to reach productive areas. The ideal season is late September through early October, before significant snows close off high passes. This hunt demands strong physical fitness, navigational expertise, and the ability to deal with high-altitude conditions. Standard Wyoming deer tags are required; wilderness permits are generally self-issued at trailheads. Trade-offs include the physical demands of high-altitude hunting, rapidly changing weather, and the presence of grizzly bears, though fewer than in the Absarokas or Thorofare. The sheer number of lakes can also make route-finding complicated. **Highlights** * Spectacular high-alpine scenery with numerous lakes and granite peaks * Excellent opportunities for spotting and stalking mule deer above timberline * Significant challenge for hunters seeking a true wilderness experience * Potential for combining a deer hunt with fishing in pristine alpine lakes * Fewer hunters willing to penetrate the deepest sections **Watch-outs** * Very high elevations, requiring acclimatization and good fitness * Abrupt and severe weather shifts, including early blizzards * Presence of grizzly bears in some areas, especially lower elevations * Route-finding can be complex due to varied terrain and numerous lakes * Long pack-in distances over difficult terrain
