In topography, prominence 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. A peak's key col is a unique point on this contour line and the parent peak is some higher mountain, selected according to various criteria.
Hoher Dachstein is a strongly karstic Austrian mountain, and the second highest mountain in the Northern Limestone Alps. It is situated at the border of Upper Austria and Styria in central Austria, and is the highest point in each of those states. Parts of the massif also lie in the state of Salzburg, leading to the mountain being referred to as the Drei-Länder-Berg. The Dachstein massif covers an area of around 20×30 km with dozens of peaks above 2,500 m, the highest of which are in the southern and south-western areas. Seen from the north, the Dachstein massif is dominated by the glaciers with the rocky summits rising beyond them. By contrast, to the south, the mountain drops almost vertically to the valley floor.
Cerro Mercedario is the highest peak of the Cordillera de la Ramada range and the eighth-highest mountain of the Andes. It is located 100 km to the north of Aconcagua, in the Argentine province of San Juan. It was first ascended in 1934 by Adam Karpiński and Wiktor Ostrowski, members of a Polish andinist expedition led by Konstanty Jodko-Narkiewicz. The Polish party erected a cairn on the summit.
The Großer Priel is, at 2,515 metres above the Adriatic (8,251 ft), the highest mountain of the Totes Gebirge range, located in the Traunviertel region of Upper Austria. It ranks among the ultra prominent peaks of the Alps. Part of the Northern Limestone Alps, its steep Dachstein cliffs form the northeastern rim of a large karst plateau and are visible from afar across the Alpine Foreland.
An ultra-prominent peak, or Ultra for short, is a mountain summit with a topographic prominence of 1,500 metres (4,900 ft) or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence.
Hochtor, at 2,369 m (7,772 ft), is the highest mountain in the Ennstaler Alps, part of the Northern Limestone Alps, in Styria, Austria.
The topographic isolation of a summit is the minimum distance to a point of equal elevation, representing a radius of dominance in which the peak is the highest point. It can be calculated for small hills and islands as well as for major mountain peaks, and can even be calculated for submarine summits.
Qiajivik Mountain is a mountain in Qikiqtaaluk, Nunavut, Canada. Located in northeastern Baffin Island, it is part of the Baffin Mountains. At 1,965 m (6,447 ft) Qiajivik is the highest mountain in northern Baffin Island and with a topographic prominence of 1,787 m (5,863 ft) it is one of Canada's 142 ultra prominent peaks.
Shedin Peak is the highest mountain in the Atna Range and in the Skeena Mountains of northern British Columbia, Canada, located 77 km (48 mi) north of Hazelton at the head of Rosenthal Creek. It has a prominence of 1,798 m (5,899 ft), created by the Bear-Driftwood Pass.
Cima Dodici is a mountain on the border of Vicenza in Veneto and Trentino in Trentino Alto Adige, northern Italy, south of the village of Borgo Valsugana. It has an elevation of 2,336 metres. and is the highest peak in Vicenza. At 1,874 m prominence, it is an ultra prominent peak. The key col is near the village of Pergine Valsugana.
Arcalod is a mountain of Savoie, France. It lies in the Bauges range of the French Prealps and has an elevation of 2,217 metres (7,274 ft) above sea level.
The Grimming is an isolated peak in the Dachstein Mountains of Austria and one of the few ultra-prominent mountains of the Alps.
The Birnhorn is an isolated mountain in the Leoganger Steinberge, Northern Limestone Alps, Austria.
The Kaltwasserkarspitze is a mountain in the Hinterautal-Vomper Chain and, at 2,733 m (AA) m, is the fourth highest peak in the Karwendel mountains in Austria after the Birkkarspitze, Middle and Eastern Ödkarspitze. The Kaltwasserkarspitze is the eastern neighbour of the Birkkarspitze, its rugged summit dropping in a steep rock face to the valley of Kleiner Ahornboden. A long arête heads south from the mountain, on which are the Sägezähne and the Großer Heißenkopf and which separates the Östliche Birkkar from the Raukarl.
The Maja e Çikës, at 2,044 metres (6,706 ft) above sea level, is the highest peak of the Ceraunian Mountains. The Ceraunians extends approximately 100 kilometres (62 mi) along the Albanian Riviera in a northwesterly direction from Sarandë to the Karaburun Peninsula. With a prominence of 1,563 metres (5,128 ft), Maja e Çikës is the 85th most prominent mountain peak in Europe.
