McInnis Canyon National Conservation Area Ruby-Horsethief Canyons – Colorado River Campsite Map

The Ruby-Horsethief section of the Colorado River runs through beautiful red rock canyons and has many day hike opportunities offering both solitude and exploration. This section of the canyon, from Loma, Colorado to Westwater, Utah is a 25-mile stretch of mostly flat water with sections of Class I and II rapids. The Black Rocks section is composed of rock known as Vishnu schist, which dates back about 1.7 billion years. This same rock is exposed in certain sections of the Grand Canyon.
