Unit 17L (Salmon River Drainage — Archery)

Idaho Hunting Guide — Rocky Mountain Bighorn Sheep

Unit 17L is the archery-only limited permit hunt within the Salmon River drainage of central Idaho — one of the most spectacular and remote bighorn sheep habitats in the lower 48. The Frank Church–River of No Return Wilderness forms much of the backdrop, where canyon walls drop thousands of feet to the river. Archery tags are extremely scarce and the wilderness terrain demands self-sufficient hunters comfortable with backcountry travel.

Rocky Mountain Bighorn Sheep Hunting in Unit 17L

Unit 17L is the archery-only limited permit hunt within the Salmon River drainage of central Idaho — one of the most spectacular and remote bighorn sheep habitats in the lower 48. The Frank Church–River of No Return Wilderness forms much of the backdrop, where canyon walls drop thousands of feet to the river. Archery tags are extremely scarce and the wilderness terrain demands self-sufficient hunters comfortable with backcountry travel.

Where to Find Rocky Mountain Bighorn Sheep in Unit 17L

Sheep in the Salmon River canyon country of Unit 17L occupy the dramatic canyon walls and rocky sidehills along the Main Salmon and its tributaries. These are remote, roadless landscapes requiring float or horse access.

Main Salmon River Canyon

The steep canyon walls above the Main Salmon between Riggins and Salmon City hold resident sheep bands year-round. Glass the rocky outcrops and grassy benches on the south-facing slopes above the river from 1,500 to 5,000 feet elevation.

Tributary Drainages

Side canyons and tributary drainages feeding the Salmon provide additional habitat. Sheep move up these draws to reach higher-elevation summer range and descend to the canyon floors in winter. The transition zones between cliff faces and open bunchgrass slopes are prime feeding areas.
