Middle Fork Zone Context
Central Idaho — Middle Fork Salmon Drainage
The Middle Fork zone groups Units 20A, 26, and 27 in central Idaho. Plans here may involve the Frank Church–River of No Return Wilderness and the Middle Fork of the Salmon River. The Middle Fork river is managed for nonmotorized floating; a jet-boat approach is not authorized on that river.
If combining a hunt with a float, check river permits, launch arrangements, and hunting boundaries separately. A wilderness airstrip or stock route requires its own logistics check; neither is guaranteed by an elk-zone map.
