North Fork Owyhee Wilderness

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. Elevations within the Wilderness boundaries range from about 4,800 to 6,800 feet. 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.
