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.

High desert plateau. Dry, windy, and vast. Water is the limiting factor.
