Unit 36

Key reference points include Mount Loening, Mount Greylock, and Pinyon Peak for orientation and glassing vantage points. The Yankee Fork system—especially the West Fork Yankee Fork—provides major drainage corridors for travel and navigation. Sunbeam and Custer serve as nearby reference towns for planning.

Several named lakes including Horseshoe, Mystery, Fish, Lightning, and Hindman Lakes mark reliable water and camp locations. Red Mountain and Bonanza Peak offer additional glassing positions. These landmarks are critical for navigation in steep terrain and locating animals on high ridges.

This is upper-elevation country throughout—the entire unit sits between 5,700 and 10,300 feet, with the median elevation at 8,068 feet. Expect low, windswept alpine meadows and rocky slopes above treeline on the highest peaks and ridges. Moderately timbered subalpine slopes of whitebark pine, limber pine, and scattered spruce-fir drop into the major drainages.

Open rocky terrain dominates the ridgeline systems where bighorn sheep live. Lower drainages feature ponderosa and Douglas-fir transitions, but the overall character is high-country alpine and subalpine—steep, exposed, and treeless on the high peaks where sheep concentrate.

Two hundred sixty miles of roads provide access corridors, but most are staging routes rather than direct access to sheep habitat. State Highways 21, 44, and 55 frame the unit's perimeter. From these roads, hunters face significant backcountry travel—foot traffic and stock are the primary access methods to high-country sheep terrain.

This naturally limits hunting pressure compared to lower-elevation units. However, popular drainages near Custer and along the Yankee Fork system may see concentrated early-season pressure. The steepness and elevation demand physical capability, which naturally filters casual hunters.

Remote ridgelines away from major drainages see minimal pressure.

Unit 36 encompasses portions of Blaine and Custer Counties centered on the Salmon River drainage. The unit is bounded by the Payette River and South Fork Payette River to the north near Banks, State Highways 55 and 44 to the west, and State Highway 21 to the east. The southern extent includes the Marsh Creek drainage of the Middle Fork Salmon River.

The unit captures an extensive slice of the central Idaho backcountry, incorporating the Yankee Fork drainage system and surrounding ridgelines. This is alpine and subalpine terrain with significant vertical relief.

Water sources are limited but strategically located. The Salmon River and its South Fork provide perennial water in the main drainages but require significant descent from high sheep habitat. The Yankee Fork system—including West Fork Yankee Fork, Rankin Creek, and Red Rock Creek—offers reliable flowing water at mid-elevations.

High-country creeks like Trail Creek, Sawmill Creek, and Sevenmile Creek are seasonal but important for alpine travel. Several named lakes provide reliable water at elevation but require navigation to accessible basins. Late-season hunting demands knowledge of spring locations and persistent snowmelt.

Unit 36 is bighorn sheep country in rugged high-altitude terrain. Success depends on glassing from distance using optics to locate sheep on rocky ridges, then executing long stalks across steep country. Early season may see sheep at slightly lower elevations in the subalpine zone; peak rut occurs in late season.

Utilize the lake basins and high drainage heads as approach routes. Water scarcity means sheep concentrate near reliable springs and creeks—scout these areas during preseason if possible. Physical fitness is essential; many successful hunts require 8,000+ vertical feet of elevation change over multiple days.

Pack light and plan for extended backcountry camps. Spring hunting during green-up often concentrates sheep in accessible terrain before summer dispersal.
