Unit 146

Fish Creek

High-elevation timbered ridges and rolling basins along the Continental Divide near Grand Teton.

Hunter's Brief

Unit 146 sits in the upper reaches of the Gros Ventre drainage, a mix of dense forest and open parks at elevation between 7,400 and 10,450 feet. Rolling topography with scattered meadows breaks up the timber. Access relies on Forest Service roads—primarily the Moccasin Basin and Union Pass roads—that provide fair vehicle access to staging areas, though the road network is moderate and not densely connected. Limited water sources and moderately complex terrain mean careful trip planning. Both mule deer and whitetail inhabit the unit, using meadows and timbered slopes.

Terrain Deep Dive

Landmarks & Navigation

The Continental Divide anchors the northern boundary and provides a strategic spine for navigation and glassing. Bacon Ridge and Burnt Ridge offer elevated vantage points for surveying the rolling country below. Lava Mountain and Sunday Peak serve as visible reference points.

Sheridan Pass marks a key crossing. Named creeks—Hackamore, Leeds, Packsaddle, and No Feed Creek—trace drainages useful for navigation and water searches. Purdy Basin provides open terrain for midday glassing, while the meadows (Buffalo, Park Creek, Washakie) concentrate deer and elk movement, particularly during transitions between timber and open ground.

Elevation & Habitat

Terrain rises from 7,421 feet in the Gros Ventre River drainage to above 10,450 feet along the Continental Divide crest. Elevation bands compress into the upper half of the spectrum, creating a predominantly high-country unit. Dense forest—primarily lodgepole and subalpine fir—covers most slopes, with pocket meadows and parks interspersed throughout (Park Creek Meadow, Buffalo Meadow, Washakie Park, Purdy Basin). These clearings are critical elk and deer habitat in a sea of timber.

The rolling topography means gentle slopes in places, steeper pitches elsewhere—not a mountainous knife-edge but substantial elevation change between drainage bottoms and ridge crests.

Access & Pressure

Forest Service roads provide the primary access backbone: the Moccasin Basin Road (USFS 30750) and Union Pass Road (USFS 600) connect to staging areas. The Darwin Ranch Road (USFS 620) offers additional routing. Total road mileage approaches 175 miles, but road density is not exceptionally high, suggesting main arteries with less connected secondary routes.

Access is fair—not locked down but requiring navigation and trip planning. Most hunters enter from the south (Gros Ventre River valley) or northwest (Union Pass area). The moderate terrain complexity and fair access mean the unit absorbs regular pressure but large tracts remain quieter if hunters venture beyond main roads.

Boundaries & Context

Unit 146 encompasses terrain along the Gros Ventre River drainage between Kinky Creek and Fish Creek, bounded on the north by the Continental Divide. The unit wraps around the eastern slope of the Divide in the Absaroka-Beartooth country, roughly 30-40 miles northwest of Jackson. Grand Teton National Park and Bridger-Teton National Forest define the western and northern context.

The unit is entirely above 7,400 feet, occupying the transition zone between lower valley drainages and the high spine of the Continental Divide. Size is moderate—substantial enough to absorb pressure but navigable in a few days of hunting.

Water & Drainages

Water sources are limited despite the upper elevation. The Gros Ventre River anchors the southern boundary and provides reliable water at lower elevations, but the headwater tributaries (Fish Creek, North Fork Fish Creek, Kinky Creek, and smaller feeder streams) run seasonally or spring-dependent. Hackamore Creek, Lloyd Creek, and other named drainages support seasonal flow.

Hunters must plan water locations carefully—relying on springs and perennial creeks rather than assuming continuous water. Early season may offer better water access as snowmelt feeds drainages; late season requires knowledge of reliable seeps and springs. This limitation shapes camp placement and daily hunting range.

Hunting Strategy

Mule deer and whitetail use the meadow-and-timber mosaic throughout the elevation band, concentrating in transition zones where forest meets park. Early season finds deer in high parks and along ridgetop transitions; as temperatures drop and snow pushes animals lower, focus shifts to middle-elevation timbered draws and the meadows that remain accessible. The Continental Divide and ridge systems provide glassing opportunities for spotting deer on open parks and benches.

Most productive hunting involves walking the edge between forest and park, glassing Purdy Basin, Buffalo Meadow, and Washakie Park from distance, then stalking into timber or open ground depending on wind and animal location. The rolling terrain rewards methodical coverage of multiple drainage systems. Limited water means camps must anchor near reliable sources like the Gros Ventre or perennial creeks; from there, make daily loops into adjacent basins and ridges.
