What defines a mountain? A mountain rises above its surroundings. At the same time, not every small elevation is considered a mountain. So what criteria decides what is and what isn’t a mountain? With the help of geography, a mountain can be described objectively. The most important feature of a mountain is its height above sea level. Mountaineers often strive to conquer certain thousand-metre markers. The topographic prominence measures the independence of a summit. Depending on its location, a mountain in the Alpine foothills that is only a few hundred metres high can seem more impressive than a sub peak with a height of over 4 000 metres in the Mont Blanc or Monte Rosa massif.
