Musala ; from Arabic through Ottoman Turkish: from Musalla, "near God" or "place for prayer" is the highest peak in the Rila Mountains, as well as in Bulgaria and the entire Balkan Peninsula, standing at 2,925.42 metres (9,597.8 ft).
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.
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak, and zenith are synonymous.
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 thus do not achieve enough topographic prominence.
This article comprises three sortable tables of major mountain peaks of Canada.
The most isolated major summits of Europe by topographic isolation are located in the European continent and its tectonic and geographic boundaries. This includes major mountain peaks of fold and fault-block mountains, and also volcanoes, located not only in the European Mainland, but also those located on lands and islands on the limits of Europe, like the North Atlantic Ocean islands of the Azores and Iceland, the Arctic Ocean islands of Jan Mayen, Svalbard archipelago and Novaya Zemlya archipelago, the Mediterranean island of Sicily, the Ural Mountains, and Mount Elbrus. The last mentioned is HP of the transboundary Caucasus Mountains and Greater Caucasus region, but as a geologically separate stratovolcano, it is entirely laying in Europe, 20 km (12 mi) north of the main ridge of the Greater Caucasus, considered as the one that is forming the limits of Europe. The definition excludes island clearly lying on the African Plate and outside the geographic limits of Europe, like the Canaries and Madeira. The active volcano of Mount Etna is somehow on, or just outside the boundaries of the Eurasian Plate, resting on the subduction boundary where the African tectonic plate is being pushed under the Eurasian plate, but geographically is part of Europe, and is also included in the Top 10 lists.
