The Simplon Valley or Divedro Valley ( German : Simplontal , Italian : Val Divedro ) is a valley of the Alps , situated between the Pennine and the Lepontine ranges. The valley is drained by the Diveria or Chrummbach , a tributary of the Toce at Crevoladossola . The Simplon Valley is the only valley of Valais located south of the main chain of the Alps .
6-691: The highest mountains in the valley are the Weissmies (4,017 m), the Lagginhorn (4,010 m) and the Fletschhorn (3,993 m), all in the Pennine Alps. On the other side (Lepontine Alps), the highest summit is Monte Leone (3,553 m). The most important pass in the valley is the Simplon , connecting Brig to Domodossola . The valley is politically divided between Switzerland and Italy . The upper western part belongs to
12-610: Is a mountain in the Pennine Alps in the canton of Valais in Switzerland near the village of Saas-Fee . It is the easternmost four-thousander of its range. The Weissmies is located on the main Alpine chain , on a massif separating the Saastal valley on the west and Simplon valley on the east. The massif consists of two other main summits lying to the north at almost the same altitude,
18-668: The Lagginhorn and Fletschhorn . The mountain lies between the Lagginjoch (3,500 m) to the north and the Zwischbergen Pass (3,260 m) to the south. The Weissmies is one of the 10 four-thousanders surrounding the Saastal , facing the Dom on the west, the third highest summit of the Alps . It was first climbed by Jakob Christian Häusser and Peter Josef Zurbriggen in 1855 via the Triftgrat. The ascent
24-659: The Swiss canton of Valais and the lower eastern part belongs to the Italian region of Piedmont . The international border runs from the Camoscellahorn to Monte Leone, reaching an altitude of 800 metres at valley floor. The main localities are Simplon , Gondo (Switzerland), Iselle , Trasquera and Varzo (Italy). 46°11′49″N 8°09′07″E / 46.19694°N 8.15194°E / 46.19694; 8.15194 Weissmies The Weissmies 4,013 m (13,166 ft)
30-538: Was climbed in 1884 by C. H. Wilson, A. Burgener, J. Furrer. Two weeks later, W. H. and E. Paine with T. Andenmatten and P. Zurbriggen opened a route on the northern ridge. The approach to the Trift Glacier/south-west ridge (Triftgrat) route can now be made via lift to Hohsaas (3,100 m), which is located virtually at the edge of the glacier . The ascent from Hohsaas takes about 4 hours and involves slopes to 40 degrees and crevasses . Another route starts from
36-459: Was mired in some controversy as the local guides did not believe that the peak could be ascended without their help; when they themselves ascended to the summit by following Häusser and Zurbriggen's footprints, they found that the highest point had indeed been reached. The east face was climbed first by J. A. Peebles, Mr E. P. Jackson and Margaret Jackson with guides P. Schlegel, U. Rubi and J. Martin on 17 October 1876. The more difficult south face
