Unit 110

Grinnell

Alpine and subalpine terrain carved by the North Fork Shoshone drainages with steep ridges and high mountain basins.

Hunter's Brief

Unit 110 spans high-country ridges and alpine basins between 6,000 and nearly 12,000 feet, centered on the North Fork Shoshone River drainage. Access is moderate with roughly 220 miles of road, though terrain becomes increasingly rugged at higher elevations. Water sources are scattered but reliable in the main drainages and several named streams. Expect steep, complex country with significant elevation gain and descent—this is demanding terrain that rewards careful navigation and patience for both mule deer and whitetail.

Terrain Deep Dive

Landmarks & Navigation

Notable peaks including Monument Mountain, Mount Chittenden, and Notch Mountain provide critical glassing and navigation points across the high country. Fishhawk Glacier distinguishes the northern terrain, while Paradise Valley offers a recognizable natural feature for orientation. The Palisades cliff system marks significant terrain breaks.

High meadows including Fishhawk, Eagle Creek, and Sam Berry Meadow serve as focal points for hunting and natural gathering areas. Hughes Basin, Silvertip Basin, and Glacier Basin are distinct high-country bowls worth targeting. These landmarks are spread across steep terrain, making them useful for distance glassing and route planning rather than quick reference points.

Elevation & Habitat

Elevations rise from approximately 6,000 feet in the river valleys to nearly 12,000 feet on the highest peaks, with most terrain concentrated in the 8,000 to 10,000-foot band. Lower drainages hold scattered forest and meadow interspersed with sagebrush and aspen, transitioning rapidly into lodgepole and spruce-fir forests on mid-elevation slopes. Above 10,000 feet, timber becomes sparse and stunted, giving way to alpine tundra and rocky summits.

Fishhawk Glacier and several high basins represent the most extreme alpine terrain. This vertical arrangement creates multiple distinct habitat zones within a relatively compact footprint.

Access & Pressure

Approximately 220 miles of road enter the unit, primarily via drainage bottoms and lower-elevation approaches, providing fair access to river valleys and lower slopes. However, road density doesn't translate to easy hunting—the roads end where steep terrain begins, forcing hunters to foot it into most productive country. Main access likely concentrates around river corridor and lower drainage approaches, creating pressure zones near trailheads.

Vast acreage of upper-elevation terrain remains relatively inaccessible without significant climbing. Early season sees increased pressure in accessible lower areas; higher elevations see less competition due to elevation gain and complexity. Planning routes to avoid concentrations of people is essential on this unit.

Boundaries & Context

Unit 110 encompasses the northern and southern drainages of the North Fork Shoshone River, bounded by Clearwater Creek on the upper end and Elk Fork Creek on the lower end. The unit sits in the high country of northwestern Wyoming's mountain terrain, creating a substantial vertical relief zone from mid-elevation river valleys to alpine summits. Pahaska Tepee marks a reference point on the western edge.

The North Fork Shoshone forms the primary geographic spine, with numerous tributary drainages creating distinct subunits within the larger terrain. Most terrain is public land with steep, complex topography throughout.

Water & Drainages

The North Fork Shoshone River is the primary water corridor, with reliable flow throughout the unit. Key tributaries include Hughes Creek, Gunbarrel Creek, Libby Creek, Grinnell Creek, and Jones Creek—all significant drainages worth following for both water access and game movement. Mormon Creek, Moss Creek, Aspen Creek, and Neva Creek provide supplementary flow.

Newton Spring and several unnamed springs are scattered across the high country. Water becomes limiting in the highest basins during late season, making drainage bottoms important hunting concentrations. Early season offers better water distribution, while late-season hunting requires knowledge of reliable spring locations and perennial creeks.

Hunting Strategy

Unit 110 holds both mule deer and whitetail deer across its elevation zones, each using distinct habitats. Mule deer concentrate in mid-elevation forests and high basins, particularly around spruce-fir transitions and alpine parkland where they feed in meadows then retreat to timber. Whitetail prefer lower drainages with denser cover, moving through riparian corridors and aspen breaks.

Early season (September) allows glassing high basins and parks for mule deer before early snows. By October, deer migrate downslope, concentrating in transitional terrain where timber meets meadow. Late season sees both species in lower drainages with available water and remaining vegetation.

The terrain's complexity demands careful route planning, thorough glassing, and willingness to cover significant vertical distance. Success depends on reading elevation-driven movements and water availability.
