Here’s a photo to get your heart racing. The massive stone column at Devils Tower National Monument in Wyoming – known as “Bear’s Lodge” or “Bear’s Tipi” to local tribes – rises 867 feet from its base. Hundreds of parallel cracks divide Devils Tower into large hexagonal columns, making it one of the finest traditional crack climbing areas in North America. Approximately 5,000 climbers a year test their skills on this amazing natural tower. Photo by National Park Service.
