Another site I found says that the Mountain Station is at 670 meters, leaving an elvation differential of 1443 meters, but that the western route involves the loss and regain of 300 meters as one crosses over the summit of Vierramvare at 1800 meters, leading to a total elevation gain of 1742 meters or 5,720 feet.
