The North Fork Owyhee River consists of steep vertical walled canyon ranging in depth from 200 to 500 feet. As it flows toward Oregon, the canyon changes from a landscape dominated by rhyolite monoliths and pinnacle formations to one engulfed in sheer walls of blocky basalt. The river shoreline is lined with groves of mature and old-growth juniper woodlands. During high spring flows, a portion of this river is used by expert boaters as an outstanding Class V whitewater run.
