TETON VILLAGE, WY \u2014 Jackson Hole Mountain Resort expanded its Via Ferrata this summer with four new routes open now through September 29. JHMR is home to the first-ever US Forest Service-approved Via Ferrata on public land. The new routes add options, challenge, and new features like a cable ladder and two different types of bridges. The Ferrata carries guests over Teton granite slabs, through cracks, overhangs, and caves. \u201cWe are proud to open new and additional challenging features to the Via Ferrata,\u201d says JHMR President Mary Kate Buckley. "This has been a hugely popular activity at JHMR, and we are excited about seeing it grow this summer with the expansion of this terrain. There are now routes for all types of abilities, and a sense of progression from the easier routes to the most difficult.\u201d The Via Ferrata opens some of the classic steep, rugged terrain that the Tetons are known for with guided ascents, and allows JHMR to offer the same thrilling and authentic guided mountain experience via climbing in the summer as with skiing in the winter. A guided rock climbing activity, most often translated to \u201ciron ways\u201d or \u201ciron pathways,\u201d ferrata systems were initially built in Italy to move military units and equipment through the Dolomite Mountains during World War I. They involved not only cables and platforms fastened to the sides of mountains, but occasional connections to extensive tunnel systems. The ferratas were later restored and upgraded by the Italian Alpine Club. Today they are popular tourist attractions in Italy, Switzerland, Austria, France, Germany, Spain and increasingly in North America.
