At the western rim of the Grand Canyon (the side closest to Las Vegas), the Native American Hualapai Tribe hosts the Grand Canyon Skywalk. Opened in 2007, this cantilevered glass bridge is suspended 4,000 feet above the Colorado River and the magnificent Grand Canyon below. It is truly breathtaking and inspires one to know how an eagle must feel soaring freely in and around this incredible ancient landmark. Ancient indeed—the National Park Service's Web site notes that the rocks exposed by the canyon are up to two billion years old, and then adds: "The Canyon itself—an ‘erosional’ feature—has formed only in the past five or six million years.”Brenda Calvin is the founder and president of The Calvin Group, LLC.
