The Owyhee River carves narrow canyons of sheer rhyolite and basalt walls hundreds of feet deep into the sagebrush and grassland high desert sprawling over southwestern Idaho and eastern Oregon. An area four times the size of Yellowstone, it’s the loneliest corner of the Lower 48. It’s hard just to get there because of the few, bad roads. Check out the canyons of the Owyhee in this slideshow. Then read my story about our eight-day, 82-mile kayaking descent of the upper Owyhee River, where we saw just one other kayaker, on our last night, a couple miles before the takeout.
