About this map

The Jarbidge River carves a deep path through this high-elevation landscape along the border of Nevada and Idaho during the mid-1980s. This survey focuses on the protected lands within the Humboldt National Forest and the Jarbidge Wilderness, where sharp elevation changes define landmarks like Biroth Ridge and Cougar Point. The drainage patterns of the East Fork Jarbidge River and the numerous springs feeding Poison Creek reveal the complex hydrology of this remote interior region.

While the map shows few permanent structures, it documents the important network of Pack Trail routes that provided the only access to the Jarbidge Wilderness interior. Topographic features such as Robinson Hole and the distinct plateaus of Wilkins Island and Little Island illustrate the erosive power of the river system. The state line between Idaho and Nevada and the boundary between Owyhee and Elko counties run through this terrain, marking a strictly regulated landscape defined by natural borders and wilderness protection.
