Unit Nine Mile, Range Creek

Nine Mile Canyon and Range Creek form the two dominant drainages, with their steep canyon walls providing unmistakable navigation corridors and natural travel routes. The Book Cliffs and Roan Cliffs to the north create dramatic skyline features visible for glassing and orientation. Key benches—Horse Bench, Last Chance Benches, Big Horn Benches—offer elevated vantage points and thermal cover.

Summits like Big Horn Mountain, Xmas Mountain, and Blue Castle Butte serve as triangulation points across the complex terrain. The Green River to the east provides a permanent boundary reference. Multiple named springs (Mac, Hanging Rock, Buckhorn, Bear Springs) dot the landscape but require advance knowledge to locate reliably.

Terrain spans from low river bottoms near 4,000 feet to high plateaus and ridge systems exceeding 10,000 feet, creating distinct habitat transitions. Lower elevations feature sagebrush-covered benches and canyon bottoms with scattered juniper and pinyon. Mid-elevation slopes transition into ponderosa and mixed conifer forest on ridges and plateaus like the West Tavaputs and Beckwith Plateau.

Upper elevation terrain supports denser forest and alpine meadows. This vertical relief creates classic migration corridors for elk and mule deer, with early-season animals in high country descending to sagebrush and canyon floors as conditions shift. The moderate forest density means glassing opportunities exist throughout.

This unit presents a stark access paradox: over 1,000 miles of roads exist, yet nearly all land is private, requiring written landowner permission before hunting. Major roads penetrate Nine Mile Canyon and access Range Creek, allowing vehicle access to key drainages, but these same roads concentrate pressure on accessible corridors. Vast backcountry remains reachable only by foot, and private ownership limits legal travel options dramatically.

The high terrain complexity score (8.9/10) reflects navigation difficulty beyond just steepness—canyon mazes, plateau transitions, and limited landmarks make route-finding challenging. Hunters willing to navigate private-land logistics and hike beyond roadheads will find vastly less pressure than main-road staging areas.

The unit sprawls across three counties between Green River and the Price area, bordered by I-70 to the south and US-191 to the west. Nine Mile Canyon Road and Range Creek form the primary geographic spine, running northeast through the heart of the unit toward the Green River boundary. The eastern edge follows Nine Mile Creek to its confluence with the Green River, creating a natural boundary along this major waterway.

Swasey's Boat Ramp marks the southern terminus before Hastings Road leads back to SR-19. The unit's vast size and rolling topography are partially offset by its near-complete private ownership, which fundamentally shapes access and hunting patterns.

Nine Mile Creek and Range Creek are the lifeblood of this unit, flowing year-round and providing reliable water access in otherwise arid country. Hoffman Creek, Gordon Creek, and numerous smaller drainages (Argyle, Dugout, Fish, Deadman, Minnie Maud) offer seasonal or intermittent flow. Scattered springs exist throughout but are unreliable without detailed local knowledge.

Several reservoirs (South, Andersons, Kiahtipes, Grassy Trail) and ponds provide secondary water sources, though many may be private or inaccessible. The Green River boundary to the east offers water but presents a major navigation barrier. Limited water beyond the main creeks demands careful route planning and water cache strategies.

This unit supports elk, mule deer, moose, pronghorn, mountain goat, bighorn sheep, desert sheep, black bear, mountain lion, and bison—a diverse big-game portfolio tied to elevation and habitat diversity. Elk thrive in mid-elevation forests and canyon transitions, with early-season animals in high country descending to sagebrush benches and riparian corridors by late season. Mule deer follow similar patterns but occupy more open, brushy terrain at lower elevations.

Moose are tied to riparian zones and willow bottomlands along creeks. Pronghorn inhabit open sagebrush flats and benches. Goats and bighorn occupy cliff systems and upper ridge terrain—glassing from distance is critical.

The complex terrain rewards methodical, pre-scouted approaches. Private-land access requirements demand building relationships or hiring outfitters, which separates serious hunters from casual applicants.
