The Dent Blanche is a mountain in the Pennine Alps, lying in the canton of Valais in Switzerland. At 4,357 m (14,295 ft)-high, it is one of the highest peaks in the Alps.
An arête is a narrow ridge of rock that separates two valleys. It is typically formed when two glaciers erode parallel U-shaped valleys. Arêtes can also form when two glacial cirques erode headwards towards one another, although frequently this results in a saddle-shaped pass, called a col. The edge is then sharpened by freeze-thaw weathering, and the slope on either side of the arête steepened through mass wasting events and the erosion of exposed, unstable rock. The word arête is French for "edge" or "ridge"; similar features in the Alps are often described with the German equivalent term Grat.
The Großglockner, or just Glockner, is, at 3,798 metres above the Adriatic (12,461 ft), the highest mountain in Austria and highest mountain in the Alps east of the Brenner Pass. It is part of the larger Glockner Group of the Hohe Tauern range, situated along the main ridge of the Central Eastern Alps and the Alpine divide. The Pasterze, Austria's most extended glacier, lies on the Grossglockner's eastern slope.
In topography, prominence or relative height measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. The key col ("saddle") around the peak is a unique point on this contour line and the parent peak is some higher mountain, selected according to various criteria.
The Aiguille de Bionnassay is a mountain in the Mont Blanc massif of the Alps in France and Italy. It has been described as "one of the most attractive satellite peaks of Mont Blanc", and is located on its western side. The mountain's south and east ridges form the frontier between the two countries, and its summit is a knife-edge crest of snow and ice. Reaching it via any route provides a "splendid and serious snow and ice climb".
The Grand Combin is a mountain massif in the western Pennine Alps in the canton of Valais. At a height of 4,309 metres (14,137 ft) the summit of Combin de Grafeneire is one of the highest peaks in the Alps and the second most prominent of the Pennine Alps. The Grand Combin is also a large glaciated massif consisting of several summits, among which three are above 4000 metres. The highest part of the massif is wholly in Switzerland, although the border with Italy lies a few kilometres south.
La Meije is a mountain in the Massif des Écrins range, located at the border of the Hautes-Alpes and Isère départements. It overlooks the nearby village of La Grave, a mountaineering centre and ski resort, well known for its off-piste and extreme skiing possibilities, and also dominates the view west of the Col du Lautaret. It is the second highest mountain of the Écrins after the Barre des Écrins.
The Aiguille Blanche de Peuterey is a mountain of the Mont Blanc massif in Italy. It is considered the most difficult and serious of the alpine 4000-m mountains to climb.
The Aiguille d'Argentière is a mountain in the Mont Blanc massif on the border between France and Switzerland. The second highest summit of the Aiguille d'Argentière is the prominent rock-tower Flèche Rousse southeast of the main-summit.
Mont Blanc de Courmayeur is a point on the south-east ridge of Mont Blanc that forms the peak of the massive south-east face of the mountain. It is connected to the main summit via the Col Major.
The Aiguille Noire de Peuterey is a mountain of the Mont Blanc massif in Italy, forming part of the Peuterey ridge to the summit of Mont Blanc with its higher neighbour, the Aiguille Blanche de Peuterey.
At the height of 3,770 metres (12,370 ft) the Kleinglockner is the third highest mountain summit in Austria. However, with a prominence of only 17 metres it is arguable whether it can be counted as an independent mountain, or just as a subpeak of the Großglockner. It lies in the Glockner Group of Austria's Central Alps, the middle section of the Hohe Tauern. Geographically and geologically speaking, it is viewed a secondary summit of the neighbouring Großglockner, but in the literature, in view of its importance to mountaineering, it is in some cases treated as separate. Its peak forms part of the Glockner crest or ridge (Glocknerkamm) and lies exactly on the border between the Austrian state of Carinthia and Lienz District in the East Tyrol. The Kleinglockner has the shape of a sharp edge, covered with the so-called Glockner Cornice (Glocknerwechte) and, depending on the conditions, can make the ascent of the mountain dangerous to almost impossible. The climbing history of the Kleinglockner is closely linked to that of the Großglockner, because the first climbers, coming from the south and east, had to cross it.
The saddle between two hills or mountains is the region surrounding the saddle point, the lowest point on the line tracing the drainage divide connecting the peaks. When, and if, the saddle is navigable, even if only on foot, the saddle of a (optimal) pass between the two massifs, is the area generally found around the lowest route on which one could pass between the two summits, which includes that point which is a mathematically when graphed a relative high along one axis, and a relative low in the perpendicular axis, simultaneously; that point being by definition the col of the saddle.
The Große Möseler, also called the Mösele, is a mountain, 3,480 m (AA), and thus the second highest peak in the Zillertal Alps after the Hochfeiler (3,509 m). It lies on the Zillertal main ridge which forms the border here between the Austrian state of Tyrol and the Italian province of South Tyrol. Its great size makes it the dominant mountain in the area. Seen from the northwest it appears like a firn-covered dome; but from the northeast as a regularly shaped cone of rock. Prominent arêtes radiate from the peak to the northwest, east and south. The mountain is easily ascended from the Furtschaglhaus and is often visited as a result. It was first climbed on 16 June 1865 by G. H. Fox, Douglas William Freshfield and Francis Fox Tuckett with mountain guides, François Devouassoud from Chamonix and Peter Michel from Grindelwald, as well as two unknown bearers.
The Große Bärenkopf or Weißer Bärenkopf is a twin-topped mountain in the Glockner Group in the Fuscher/Kapruner Kamm of the High Tauern, a range in the Austrian Central Alps. The mountain lies exactly on the border between the states of Salzburg and Carinthia.
The Jochköpfl is a mountain, 3,143 m (AA), on the Windach-Brunnenkogel-Kamm, a subgroup of the Stubai Alps in Austria.
The Küchlspitze is a three-thousander in the Verwall between the valley of Stanzer Tal and Paznaun in the western North Tyrol in Austria.
Émile Rey was an alpine mountain guide from Aosta Valley in Italy. Dubbed "the Prince of Guides" in Courmayeur, he was one of the most renowned guides at the end of the 19th century, making many first ascents on some of the highest and most difficult mountains in the Mont Blanc massif of the Alps. He has been described as "one of the greatest guides of his generation."
