Unit 49

Key navigation features include the Pioneer Mountains as the eastern backbone, with named peaks like Hyndman and Johnstone that anchor orientation across the high country. The Wood River system provides a major drainage corridor, flowing north through the unit with the South Fork and East Fork as key tributaries for navigation and water access. Lava Lake and Lower Box Canyon Lake serve as recognizable water features in the upper country.

The gap systems—P K Pass, Muldoon Summit, Bradley Summit—offer natural saddles for accessing high ridges. Jasper Flats and Burgess Flats provide open glassing areas where pronghorn can be spotted.

The unit spans nearly 8,000 vertical feet, from lower sagebrush valleys around 4,750 feet to alpine terrain above 11,900 feet in the Pioneer crest. Most productive hunting occurs in the middle elevation band where sagebrush benches transition into scattered timber. Ponderosa and lodgepole pine appear at higher elevations, but overall forest coverage is sparse, leaving vast expanses of open sage and scattered juniper that characterize the terrain.

The lower valleys support dense sagebrush with greasewood in wetter draws, while ridges and peaks feature alpine meadows and barren rock.

Nearly 926 miles of roads crisscross the unit, creating fair but not dense access; most are forest service routes requiring high-clearance vehicles. Highway 75 and U.S. 20 provide paved entry points, but backcountry hunting requires driving primitive roads or foot access from trailheads. The proximity to Ketchum and Sun Valley means weekend pressure can concentrate near popular trailheads and lower elevations.

However, the unit's vast size and steep terrain distribute hunters thinly; those willing to climb and hike into the sagebrush benches and high valleys can find solitude. Private land near towns limits some access corridors, channeling hunters into specific public entry routes.

Unit 49 encompasses a large section of Blaine County centered on the Ketchum-Sun Valley area, bounded roughly by Highway 75 to the west, U.S. 20 to the north, and the watershed divides of the Wood River system. The unit includes portions of the Pioneer Mountains and extends down through the productive Wood River valleys where private ranches and residential areas intersect public land. Towns like Ketchum, Bellevue, and Sun Valley sit within or adjacent to the unit, serving as logical access points, though much of the hunting country lies in the higher elevations and more remote valleys to the south and east.

Water is scattered but present in key locations. Perennial streams include the East Fork and South Fork of the Wood River system, which support willow corridors and camping opportunities. Springs are critical in the sagebrush country: Strode Spring, Timber Butte Spring, and Chokecherry Spring represent reliable water for mid-country hunting.

Higher elevation lakes like Lava Lake and the Box Canyon Lakes hold water year-round but require alpine access. Many summer springs dry by fall, making route planning essential. The South Fork and Lime Creek drainages provide the main water arteries through the lower valleys.

Pronghorn are the primary species for this unit, inhabiting the open sagebrush flats and benches where visibility is excellent. Early season hunting focuses on lower-elevation sage country and the flats (Jasper, Burgess, Campbell Flats) where pronghorn congregate before thermal pressures move them higher. Mid-season requires glassing ridge systems and open slopes; the steep terrain creates thermals that push pronghorn into predictable patterns.

Water sources become critical in late summer and fall—hunting near reliable springs and the Wood River drainage increases encounter odds. Success depends on spotting-and-stalking across open country with minimal cover; early morning and evening glassing from elevated vantage points is essential. The terrain complexity demands good map reading and navigation skills to access productive areas without excessive pressure.
