Unit 40 Boundary
That portion of OWYHEE COUNTY within the following boundary: beginning on the Snake River at the Idaho-Oregon State line, upstream to Grand View, then southeast on State Highway 78 to Mud Flat Road, then southwest on Mud Flat-Juniper Mountain Road to the North Fork of the Owyhee River, then downstream to the Idaho-Oregon state line, then north along the state line to the point of beginning.
Owyhee Zone Context
Southwest Idaho — Owyhee Canyonlands
Owyhee is high-desert hunting at scale — over a million acres of BLM canyon-and-rim country. Elk presence is limited and migration-driven; the zone is more associated with mule deer, antelope, and chukar.
Water sources are the strategic key. Marsing, Jordan Valley (Oregon), and Bruneau are the only meaningful resupply points.
