Unit 156

Two Ocean Mountain and Mount Leidy serve as major reference points for understanding the unit's ridge system—both visible from distance for glassing and orientation. Moccasin Basin at the southern edge provides a logical landmark for navigating the Continental Divide transition zone. The major creek drainages—Dallas Fork, Brush Creek, Coal Creek, and the North and South Forks of Ditch Creek—function as the primary navigation corridors through dense forest, making them critical for hunters working through the backcountry.

Gunsight Pass on the northern end offers passage between major drainage systems. The scattered high lakes (Marys Lake, Square Lake, Hidden Lake, Dallas Lake) and reservoirs mark water locations valuable for both glassing benches and as reference points when navigation gets complex in the rolling terrain.

The unit spans from mid-elevation forest around 6,700 feet up through dense conifer country approaching 10,600 feet, with most terrain sitting between 8,000 and 9,500 feet. Heavy timber—primarily spruce and fir—blankets the ridges and slopes, creating classic high-country elk and deer habitat. Scattered meadows and park areas like Preacher Park, Blackrock Meadows, and Skull Creek Meadows punch through the forest canopy, providing summer forage and seasonal hangout areas.

The rolling topography prevents any single elevation zone from dominating, creating a patchwork where game can move between timbered shelter and open feeding grounds relatively easily. Aspect variation across the drainages means some south-facing slopes thin out slightly, offering transitional habitat between dense forest and open slopes.

Over 430 miles of road infrastructure service the unit, accessed primarily from the west via US 26-287 and from trailheads off USFS roads like Road 30750 descending from Togwotee Pass. The road network allows hunters to penetrate deeper than foot traffic alone, though many roads are USFS roads rather than maintained highways and may present seasonal challenges. The western boundary proximity to Grand Teton National Park and proximity to Jackson create moderate pressure zones, particularly near established trailheads and lower-elevation access points.

However, the rolling, forested terrain limits visibility and concentrates hunters in creek drainages rather than spreading them across open ridges. Dedicated hunters moving away from major drainages can find quieter country—the dense forest and rolling topography mean that off-trail navigation rewards patient scouting.

Unit 156 occupies the eastern flank of the Teton Range, anchored by the Grand Teton National Park boundary to the west and the Continental Divide to the east. The northern boundary follows US Highway 26-287, while the southern edge traces the Gros Ventre River drainage. This moderate-sized unit wraps around the Teton backcountry in a horseshoe pattern, encompassing mixed public lands that provide solid public access percentages.

The terrain transitions from the park's high peaks downward through a complexity of ridges, basins, and creek drainages that feed major rivers—the Gros Ventre from the south and various forks joining Fish Creek from the north.

Despite the badge indicating limited water sources, the unit contains a network of creeks, reservoirs, and high-country lakes tied to the drainage systems. The North Fork and South Fork of Fish Creek form the western spine, while Ditch Creek forks and other tributaries lace through the eastern terrain. Turpin Creek, Brush Creek, Coal Creek, and Slate Creek represent other reliable options, though late-season flow can be unpredictable at elevation.

Multiple lakes and reservoirs exist—Wallace Draw Reservoir, Hardemann Reservoir, and Porter Reservoir are marked features—but these may not always be reliable for domestic water. Antelope Spring and scattered other springs provide backup options, but water planning becomes essential during early and late seasons when high-country sources freeze or diminish significantly.

Unit 156 holds both mule deer and whitetail deer across its elevation gradient, with mule deer favoring the open parks and ridge saddles while whitetails use the dense timber and creek drainages. Early season hunting focuses on the highest parks and meadows where mule deer concentrate in summer, glassing Grouse Mountain, Green Mountain, and the ridge systems above 9,000 feet. As temperatures drop, transition to the dense timber and sidehill benches where both species winter in lower-elevation pockets below 8,500 feet.

Whitetails respond well to methodical drainage stalking—work Ditch Creek, Brush Creek, and Dallas Fork where small parks provide visibility into shadowed timber. The rolling terrain demands more stillhunting and spotting-and-stalking than open-country glassing; the thick forest breaks sight lines but also provides concealment for careful approaches. Water sources become focal points during dry periods, making late-season hunts around reservoirs and reliable springs particularly productive.
