The United States Congress designated the North Fork Owyhee Wilderness (map
) in 2009 and it now has a total of 43,391 acres
All of this wilderness is located in Idaho
and is managed by the Bureau of Land Management.
The landscape within the North Fork Owyhee Wilderness, in the southwest part of Idaho near the Oregon border, is diverse, ranging from river canyons over a thousand feet deep to vast expanses of sagebrush and grassland plateaus. This ecosystem provides habitat for sage grouse, pronghorn antelope, bighorn sheep, songbirds, raptors, and numerous rare plant species. The river canyons in Owyhee County have been called the largest concentration of sheer-walled volcanic rhyolite and basalt canyons in the western United States. Many of the canyons are more than 1,000 feet deep, nearly twice as deep as the Washington Monument is tall. River enthusiasts come from around the country to challenge the famous white water rapids of these rivers.
