Rifle, Colorado, is a small town on the Colorado River, in the heart of the Rocky Mountains, that's big on natural resources. It attracts hunters, fishermen, hikers, rock climbers. Its striking scenery attracted husband-and-wife environmental artists Christo and Jeanne-Claude as well; they stretched the Valley Curtain, a 200,200-square-foot orange sheet of nylon, across 1,250-foot-wide Rifle Gap. The curtain lasted only 28 hours before another of the area's natural resources, wind, began to tear it down.
