McInnis Canyons National Conservation Area is in the high desert canyon country of western Colorado and eastern Utah, near Grand Junction, CO. It consists of approximately 123,430. Among its natural feautres are the more than 75,000 acres of the Black Ridge Canyons Wilderness, which includes the second-largest concentration of natural arches in North America. Internationally important fossils have been uncovered during more than a century of excavation. Pictograph and petroglyph sites abound, and the Old Spanish Trail, once referred to as the “longest, crookedest, most arduous mule route in the history of America,” runs through the NCA. Today, the NCA draws visitors to world-class mountain biking on Mack Ridge and along the 142-mile Kokopelli trail, which extends to Moab, Utah. Twenty-five miles of the Colorado River winds through the NCA, attracting boaters looking for straightforward floating through spectacular multi-hued sandstone canyons.
