Unit 48-1

High-elevation elk country spanning steep ridges and forested slopes above the Wood River Valley.

Hunter's Brief

This is serious alpine terrain rising from around 5,800 feet to over 11,500 feet, with steep timbered ridges and basins that demand physical conditioning. The country sits above Ketchum and the Wood River corridor, accessed via Highway 75 and various creek roads that provide entry points to the high country. You'll find reliable water in drainages like the North Fork Big Wood River and numerous alpine lakes at elevation, though lower sections run dry. Roads get you to the fringe; most hunting requires foot work into the steep terrain where elk migrate seasonally between lower winter range and high summer basins.

Terrain Deep Dive

Landmarks & Navigation

Penny Mountain and Norton Peak dominate the ridgeline system and serve as major orientation markers visible from multiple approaches. Castle Rock provides a distinct pillar landmark for navigation in the central terrain. The North Fork Big Wood River runs through lower drainages as a reliable navigation corridor.

Kelly Gulch and the various named creeks—Cherry, Mill, Boulder, Norton—provide drainage systems for both travel and water finding. Window Lake, Smoky Lake, and the Lake Creek Lakes cluster in high basins worth knowing for late-season elk concentrations. Easley Hot Springs marks the southern boundary zone.

These features form a natural grid for route planning and terrain recognition.

Elevation & Habitat

Terrain climbs steeply from the mid-elevation sagebrush and aspen margins near 5,800 feet into thick lodgepole and subalpine fir forests above 8,000 feet, with exposed alpine ridges and rocky summits pushing toward 11,500 feet. The forested middle elevations form the primary elk habitat—dense timber broken by meadows and park-like clearings where animals feed and bed. Higher ridges above timberline provide sparse graze and escape terrain.

The moderate forest cover means pockets of open country and glassing terrain, but much of the unit requires navigating thick stands where you'll rely on sign and water sources rather than long-distance visibility.

Access & Pressure

Over 620 miles of road traverse the unit boundaries and lower drainages, but most are secondary roads climbing from Highway 75 and county routes—not maintained highways. This road network provides connected access for scouting and staging camps, but the steep terrain means real hunting happens far from vehicles. The connected badge reflects valley-floor road infrastructure more than high-country accessibility; most hunters will need to walk 2-5 miles into productive country.

The moderate complexity and steep terrain naturally distribute pressure—most people stick to lower drainages and ridge saddles accessible from parking areas, leaving side basins and creek systems less crowded for those willing to work harder.

Boundaries & Context

Unit 48-1 occupies the high country east and northeast of Ketchum in Blaine County, bounded by Highway 75 on the west, the Big Wood River and Kelly Gulch on the south, and county roads tracking Croy Creek and Oakley-Goose Creek on the north and east. The unit encompasses moderate acreage of steep alpine terrain, with access anchored to the Wood River Valley floor. It's surrounded by the Ruby Mountains to the north and the Sawtooth Range framework to the east, making it a natural corridor between lower river valleys and high-elevation basins.

State Highway 27 forms the northern boundary near the transition zone between private valley lands and public mountain country.

Water & Drainages

Water exists in reliable corridors but remains limited overall. The North Fork Big Wood River and its tributaries provide consistent flow in lower and middle drainages. Cherry Creek, Mill Creek, and Boulder Creek run through defined canyons offering water access while providing navigation highways.

Higher elevations depend heavily on alpine lakes—Governors Punchbowl, Smoky Lake, Window Lake, Prairie Lakes, and Silver Lake hold water through the season. Springs like Warfield Hot Spring offer alternative sources but require specific knowledge. Lower creeks may run dry by mid-season, making understanding which water sources persist critical for late-summer and fall hunting strategies in this terrain.

Hunting Strategy

This is a pure elk unit where terrain and elevation dictate hunting approach. Early season finds animals in high-elevation basins above 9,000 feet, accessible via ridge systems and creek saddles. Mid-season and rut periods see movement toward middle-elevation parks and meadows where food concentrates, particularly around aspen and meadow transitions.

Late season presses elk to lower drainages as snow builds higher, but some may winter on lower sagebrush slopes. Glassing opportunities exist along ridgelines and from high peaks looking into basins. Success depends on scouting water and understanding seasonal migration between high summer range and lower winter country.

This unit rewards hunters who scout early and are prepared for steep climbing—the steep terrain itself is your advantage if you're in condition to hunt it.
