WY Mule Deer Backpacking Units · #1
Thorofare Wilderness (Units 100/101)
Shoshone National Forest, Wyoming, USA

The Thorofare is the epitome of Wyoming's high-country mule deer hunting. Nestled between Grand Teton and Yellowstone National Parks, this vast, remote wilderness requires a multi-day pack-in to even reach its fringes. The setting is classic Greater Yellowstone ecosystem: sprawling meadows, timbered ridges, and alpine basins, all cut by the Yellowstone River and its tributaries. What makes it special is its sheer size and remoteness; pressure from road hunters is non-existent. Access is primarily from the east via Dubois or Cody, requiring a lengthy horse pack-in or a serious backpacking trip over numerous passes. Ideal season is the late archery or early rifle season before heavy snows, typically late September through early October. This is for experienced backpack hunters with excellent physical conditioning and advanced navigation skills. Permits are standard Wyoming deer tags, but wilderness permits may be required for camping in certain areas, which are generally free but must be acquired. Trade-offs include extreme weather variability, long packing distances, and significant grizzly bear encounters. Being self-sufficient and carrying bear spray is non-negotiable. **Highlights** * Vast, roadless wilderness with minimal hunting pressure * Potential for mature, old-growth bucks * Spectacular scenery, often compared to the Tetons or Yellowstone's interior * Excellent opportunities for combined elk and deer hunts * Experience true solitude in the Lower 48's most remote wilderness **Watch-outs** * Extreme remoteness and multi-day pack-in/pack-out * High density of grizzly bears, requiring constant vigilance * Unpredictable and severe mountain weather, even in early fall * Demanding physical exertion and navigation skills required * Limited cell service and no easy bail-out points
