Unit 23
McCall
Remote mountainous terrain draining south toward the Salmon River through steep timbered canyons.
Hunter's Brief
Unit 23 encompasses steep, densely forested country in the south-draining canyons of central Idaho's Adams and Valley Counties. The terrain spans from low river valleys to high ridges, with elevation gain rewarding glassing efforts from saddles and meadow edges. Water is limited despite drainage proximity—springs and high-country lakes are scattered. Road access follows major creek drainages, but much country requires significant foot travel to reach. Expect rugged, complex terrain that filters casual pressure but demands route-finding skill.

Terrain Deep Dive
Landmarks & Navigation
Major saddles—Buck, Holbrook, Bell, Meadows Summit—provide both navigation anchors and high-ground glassing positions. Indian Mountain and Brush Mountain rise as visible reference points. Critical water navigation ties to named creeks: Fry Pan, McCrea, Twin Fork, and Star Creek drainages offer approach routes and locate reliable springs beyond the limited high lakes.
Satan Lake, Crystal Lake, and the scattered basin bottoms like Bear Basin and Rattlesnake Basin serve as destination landmarks. Meadow complexes—Chokecherry Flat, Dempsey Flat, Frosty Meadows—break the timber and offer alpine pocket hunting.
Elevation & Habitat
Terrain ranges from roughly 1,700 feet along lower creeks to above 9,300 feet on ridge summits, creating significant habitat diversity. Low-elevation river canyons support riparian vegetation and scattered ponderosa. Mid-elevation slopes transition into mixed conifer—Douglas-fir, grand fir, and spruce becoming dominant above 5,000 feet.
Higher slopes support dense subalpine forest broken by meadow pockets—Elk Meadows, Hartly Meadows, Big Creek Meadows offer glassing opportunity and early-season staging habitat. The dense forest cover throughout most elevations means travel corridors and meadow edges concentrate hunting potential.
Access & Pressure
Connected road systems follow major drainages—approximately 1,172 miles of roads provide corridor access, but density figures indicate sparse distribution across the vast landscape. Most roads are rough forest service/mining routes; pavement is limited to approach highways. This means many trailheads require rough-road navigation, filtering casual hunters.
The combination of steep terrain, dense forest, and limited road penetration creates significant portions of country accessible only by foot or horse. Light pressure likely concentrates near trailhead drainages; ridge country and upper basins receive fewer hunters.
Boundaries & Context
Unit 23 is defined by the south-draining canyons and basins tributary to the Salmon River, spanning Adams, Valley, and Idaho Counties in central Idaho. The unit encompasses a vast, mountainous region with mixed ownership dominated by public lands. The Salmon River forms a natural northern boundary, while the unit's southern extent rises into the high ridges of the Grass Mountains and surrounding peaks.
Access gateways are scattered—Riggins, New Meadows, and McCall serve as logical staging points. The terrain isolation means hunters must commit to multi-day efforts in most areas.
Water & Drainages
Water scarcity is the binding constraint. While the unit drains toward the Salmon River, mid and high-country water is limited to scattered springs (Tepee, Cannon Ball, Indian, Cold Springs) and alpine lakes (Satan, Crystal, Ruth, Morgan, Buck, Elk, Goat Lakes). Lower creeks—Fry Pan, McCrea, Twin Fork—run more reliably in spring and early season but may diminish by mid-summer. High-elevation hunting requires either spring reconnaissance or acceptance of limited water access.
Late-season hunting demands base camp near confirmed water sources.
Hunting Strategy
The steep, complex terrain (7.6/10 complexity) suits hunters comfortable with route-finding and vertical gain. Elk and mule deer are primary quarries based on habitat type. Early season targets high meadows before migration pressure; rut season focuses on ridges connecting basins.
Terrain forces tactical decisions—travel follows creek drainages, but animals winter or rut in saddle country where wind management favors glassing from distance. Spring locations become critical waypoints for multi-day hunts. Horse use or significant pack capacity is practical for units deeper than one day from roads.
Late season concentrates lower canyon country as high ridges snow over.
