It's called the Owyhee Uplands National Backcountry Byway . . . a name chosen by the Bureau of Land Management. Locals simply call it the Mud Flat Road.

It's the main connector through the huge chunk of public land in southwest Idaho managed by the BLM. The byway runs from just outside Jordan Valley, Oregon to the outskirts of Grandview, Idaho, a distance of over a hundred miles.
