Question: Where does the Glacier des Diablerets located?
Context: The Diablerets (French: "Les Diablerets" ; lit.  "the abode of devils") are a huge ice-covered mountain massif of the Alps, culminating at the Sommet des Diablerets (VD, VS) at 3210 m above sea level and straddling the border between the Swiss cantons of Vaud (VD) and Valais (VS).  The northeastern part of the massif streches also into the canton of Bern (BE). The Pointe des Berons is a mountain of the Mont Blanc Massif, located on the border between Switzerland and France.  It lies approximately halfway between the Col de Balme and the Aiguille du Tour.  The east (Swiss) side is covered by the Glacier des Berons. The Scex Rouge (also spelled "Sex Rouge"; lit.  "red rock"; 2,971 m) is a mountain of the Alps, overlooking Les Diablerets in the canton of Vaud.  Along with the Oldenhorn to the east, it is one of the main peaks of the Diablerets, a huge ice-covered mountain near the western end of the Bernese Alps, straddling the border between the cantons of Vaud, Valais and Bern, and exceeding 3,000 metres above sea level.  On its west side, the Scex Rouge is part of a nearly 2,000 metre-high amphitheatre of cliffs surrounding the Creux de Champ valley, south of Les Diablerets.  On its southeast side, the Scex Rouge overlooks the Tsanfleuron Glacier, the largest in the massif.  Administratively, the mountain is part of the municipality of Ormont-Dessus, which also includes Les Diablerets. Glacier 3000 (officially Gstaad 3000 AG) is a company that operates several cable cars and ski lifts in the region of the Diablerets in western Switzerland.  It was created in 1997 by the merging of two former companies (Reusch - Cabane des Diablerets SA, Téléphériques Pillon – Glacier des Diablerets SA).  The company is now based in Gstaad. Jackson Glacier is approximately the seventh largest of the remaining 25 glaciers in Glacier National Park located in the US state of Montana.  A part of the largest grouping of glaciers in the park, Jackson Glacier rests on the north side of Mount Jackson.  The glacier was most recently measured in 2005 at 250 acre , yet when first documented in 1850, the glacier also included the now separate Blackfoot Glacier and together, they covered 1875 acre .  Between 1966 and 2005, Jackson Glacier lost almost a third of its acreage.  When the two mountains were united prior to their separation sometime before 1929, they were known simply as Blackfoot Glacier.  In 1850, there were an estimated 150 glaciers in the park.  Glaciologists have stated that by the year 2030, many if not all of the glaciers in the park may disappear completely.  Jackson and Blackfoot glaciers have been selected for monitoring by the U.S. Geological Survey's Glacier Monitoring Research program, which is researching changes to the mass balance of glaciers in and surrounding Glacier National Park.  The glacier is being monitored using remote sensing equipment and repeat photography, where images of the glacier are taken from identical locations periodically.  Jackson Glacier is one of the easiest of the park's glaciers to observe, and is located south of the Going-to-the-Sun Road on the east side of the Continental Divide, upper St. Mary Valley. Baudissin Glacier ( ) is a tidewater glacier on the north side of Heard Island.  in the southern Indian Ocean.  Located 1 nautical mile (1.9 km) west of Challenger Glacier, Baudissin Glacier is 1.5 nautical miles (2.8 km) wide and flows into the western part of Corinthian Bay.  The terminus of Baudissin Glacier is located at the western side of Corinthian Bay, at Sealers Cove.  To the east of Baudissin Glacier is Challenger Glacier, whose terminus is located at the eastern side of Corinthian Bay, close west to Saddle Point.  To the south of Baudissin Glacier is Schmidt Glacier, and to the northwest is Atlas Cove.  Kildalkey Head is west of Schmidt Glacier.  To the south of Schmidt Glacier is Vahsel Glacier, whose terminus is at South West Bay, between Erratic Point and Cape Gazert.  Immediately south of Vahsel Glacier is Allison Glacier.

Most of the glacier is used as a ski area and is better known under the name "Glacier 3000" or "Glacier des Diablerets" (the latter is in fact a nearby smaller glacier on the summit of the Diablerets).  The area can be reached from the Scex Rouge. The Diablerets Glacier (French: "Glacier des Diablerets" ) is a glacier situated on the summit of Les Diablerets in the Bernese Alps.  It covers an area of approximatively 1 km. The Aiguille du Grépon (literally the "Needle of Grépon"), informally known as The Grepon, is a mountain in the Mont Blanc Massif in Haute-Savoie, France.  The Grepon has a Southern (3,482 m) and Northern (3,478 m) peak, which are the highest points of a sharp granite ridge to the east of the "Glacier des Nantillons" above Chamonix and northeast of the Aiguille du Midi.  A madonna statue is situated on the Southern peak. The Wildhorn is a mountain of the Alps, straddling the border between the Swiss cantons of Bern and Valais.  At 3248 m above sea level, it is the highest summit of the Bernese Alps west of the Gemmi Pass.  It forms a large glaciated massif, about 10 km wide, extending between the Sanetsch Pass and the Rawil Pass.  Along with the Muverans, the Diablerets and the Wildstrubel, the Wildhorn is one the four distinct mountain massifs of the Bernese Alps that lie west of the Gemmi Pass.  The massif of the Wildhorn is at the centre between the valleys of the Saane, Simme (both canton of Bern) and the Rhone (Valais).  It comprises several distinct summits, including (from west to east) the Arpelistock, Le Sérac, the Geltenhorn, the Sex Noir, the Sex Rouge, the Schnidehorn and the Six des Eaux Froides.  The main crest is between the glaciers named "Tungelgletscher" and "Glacier du Wildhorn".  South of the main summit is the almost equally high summit of Mont Pucel (3,177 m).  The Wildhorn is surrounded by several large mountain lakes: the Lac de Sénin, the Lauenensee, the Iffigsee, the Lac de Tseuzier and the Lac des Audannes.  The Tungelgletscher, on the north-east face, was measured as 1.9 km in length in 1973.
