Lemhi Zone Context
East-Central Idaho — Lemhi Range
The Lemhi zone covers the high, dry country between the Lemhi and Lost River Ranges, with broad valleys and steep mountain flanks. Elk populations are healthy and visibility is good — a glass-and-stalk zone more than a brush-busting zone.
Salmon is the closest supply town. Many roads cross BLM-private mosaic; check ownership before scouting.
