Ruby-Horsethief Canyon

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