Known for its dramatic canyons, white-water rapids, and eleven U.S. National Parks, the Colorado River system is a vital source of water for 40 million people in southwestern North America. Native Americans inhabited the Colorado River basin for at least 8,000 years. Between 2,000 and 1,000 years ago, the river and its tributaries fostered large agricultural civilizations. Inspired by rivers, their colors, flower lines, textures and surroundings; our designers have crafted our stunning Colorado blue ring.
